Newly developing stars shrouded in thick dust get their first baby pictures in these images from NASA’s Hubble Space Telescope. Hubble took these infant star snapshots in an effort to learn how massive stars form.
Protostars are shrouded in thick dust that blocks light, but Hubble can detect the near-infrared emission that shines through holes formed by the protostar’s jets of gas and dust. The radiating energy can provide information about these “outflow cavities,” like their structure, radiation fields, and dust content. Researchers look for connections between the properties of these young stars – like outflows, environment, mass, brightness – and their evolutionary stage to test massive star formation theories.
These images were taken as part of the SOFIA Massive (SOMA) Star Formation Survey, which investigates how stars form, especially massive stars with more than eight times the mass of our Sun.

The high-mass star-forming region Cepheus A hosts a collection of baby stars, including one large and luminous protostar, which accounts for about half of the region’s brightness. While much of the region is shrouded in opaque dust, light from hidden stars breaks through outflow cavities to illuminate and energize areas of gas and dust, creating pink and white nebulae. The pink area is an HII region, where the intense ultraviolet radiation of the nearby stars has converted the surrounding clouds of gas into glowing, ionized hydrogen. Cepheus A lies about 2,400 light-years away in the constellation Cepheus.

Shrouded in gas and dust, the massive protostar IRAS 20126+4104 lies within a high-mass star-forming region about 5,300 light-years away in the constellation Cygnus. This actively forming star is a B-type protostar, characterized by its high luminosity, bluish-white color, and very high temperature. The bright region of ionized hydrogen at the center of the image is energized by jets emerging from the poles of the protostar, which ground-based observatories previously observed.

For the 15th consecutive year, NASA received an unmodified, or “clean,” opinion from an external auditor on its fiscal year 2025 financial statements.
The rating is the best possible audit opinion, certifying that NASA’s financial statements conform with Generally Accepted Accounting Principles for federal agencies and accurately present the agency’s financial position.
“NASA has delivered a complete and reliable report of our fiscal operations, critical to our success for the Golden Age of exploration and innovation,” said NASA Administrator Jared Isaacman. “NASA’s mission drives innovation in space exploration, scientific discovery, and aeronautics, pushing the boundaries of what’s possible. Our fiscal year 2025 budget fuels economic growth, drives the growing space economy, and keeps America first amidst increasing global competition.”
The 2025 Agency Financial Report provides key financial and performance information and demonstrates the agency’s commitment to transparency in the use of American taxpayers’ dollars. In addition, the 2025 report presents progress during the past year, and spotlights the array of NASA missions, objectives, and workforce advanced with these financial resources.
“This achievement reflects our team’s diligent stewardship of NASA’s resources, including our commitment to responsibly managing taxpayers’ dollars entrusted to the agency,” said Sidney Schmidt, NASA’s acting chief financial officer. “Their unwavering dedication to sound financial management and robust internal controls ensures we uphold public trust. Congratulations and thank you to everyone involved for your commendable efforts and hard work.”
In fiscal year 2025, NASA marked significant progress toward the Artemis II test flight. Targeted to launch no earlier than Friday, Feb. 6, the Artemis II mission will send four astronauts around the Moon and back to test the systems and hardware which will return humanity to the lunar surface. NASA and its partners landed two robotic science missions on the Moon, welcomed seven new signatory countries to the Artemis Accords, and advanced medical and technological experiments for long-duration space missions like hand-held X-ray equipment and navigation capabilities.
NASA also led a variety of science discoveries, including launching a joint satellite mission with India to regularly monitor Earth’s land and ice-covered surfaces, as well as identifying and tracking the third interstellar object in our solar system; achieved 25 continuous years of human presence aboard the International Space Station; and, for the first time, flew a test flight of the agency’s X-59 supersonic plane that will help revolutionize air travel.
NASA is weeks away from sending astronauts farther than any crew has traveled before, with the agency’s second mission in its Artemis campaign. The Artemis II Press Kit now is available with information on the mission, astronauts, and other resources for media.
“Artemis II will be a momentous step forward for human spaceflight. This historic mission will send humans farther from Earth than ever before and deliver the insights needed for us to return to the Moon — all with America at the helm,” said NASA Administrator Jared Isaacman. “Artemis II represents progress toward establishing a lasting lunar presence and sending Americans to Mars. I could not be more impressed by our NASA team and the Artemis II crew, and wish them well. Boldly forward.”
Under the Artemis campaign, NASA is returning humans to the Moon for economic benefits, scientific discovery, and to prepare for crewed missions to Mars.

Through a drone flight test at NASA’s Ames Research Center in California’s Silicon Valley, researchers tested a blockchain-based system for protecting flight data. The system aims to keep air traffic management safe from disruption and protect data transferred between aircraft and ground stations from being intercepted or manipulated.
For aviation and airspace operations to remain safe, users need to be able to trust that data is reliable and transparent. While current systems have been able to protect flight data systems, cyberthreats continue to evolve, requiring new approaches. NASA researchers found the blockchain-based system can safely transmit and store information in real time.
Blockchain operates like a decentralized database — it does not rely on a single computer or centralized system. Instead, it shares information across a vast network, recording and verifying every change to a dataset. The system ensures the data stays safe, accurate, and trustworthy.
Previous cybersecurity research focused on implementing a layered security architecture — using multiple physical and digital security measures to control system access. For this test, researchers took a different approach using blockchain to address potential threats.
Using drones allowed the team to show that the blockchain framework could yield benefits across several priority areas in aviation development, including autonomous air traffic management, urban air mobility, and high-altitude aircraft.

This NASA research explored how blockchain can secure digital transactions between multiple systems and operators. The team used an open-source blockchain framework that allows trusted users real-time sharing and storage of critical data like aircraft operator registration information, flight plans, and telemetry. This framework restricts access to this data to trusted parties and approved users only.
To further examine system resilience, the team introduced a set of cybersecurity tests designed to assess, improve, and reinforce security during operations in airspace environments. During an August flight at Ames, the team demonstrated these capabilities using an Alta-X drone with a custom-built software and hardware package that included a computer, radio, GPS system, and battery.
The test simulated an environment with a drone flying in real-world conditions, complete with a separate ground control station and the blockchain and security infrastructure. The underlying blockchain framework and cybersecurity protocols can be extended to support high-altitude operations at 60,000 feet and higher and Urban Air Mobility operations, paving the way for a more secure, scalable, and trusted ecosystem.
NASA researchers will continue to look at the data gathered during the test and apply what they’ve learned to future work. The testing will ultimately benefit U.S. aviation stakeholders looking for new tools to improve operations.
Through its Air Traffic Management and Safety project, NASA performed research to transform air traffic management systems to safely accommodate the growing demand of new air vehicles. The project falls under NASA’s Airspace Operations and Safety Program, a part the agency’s Aeronautics Research Mission Directorate that works to enable safe, efficient aviation transportation operations that benefit the flying public and industry.

Il telescopio Astri-1 ha catturato il suo primo segnale gamma di origine extragalattica. Nella notte del 15 gennaio 2026, tra le 01:00 e le 03:40 ora italiane, il telescopio Cherenkov – uno dei nove che costituiscono il mini-array Astri, la struttura osservativa dedicata all’astronomia gamma da Terra situata a Tenerife, nelle Isole Canarie – ha puntato gli occhi verso il blazarMarkarian 421, registrando un incremento del flusso di raggi gamma proveniente dalla sorgente.

Markarian 421 è una delle sorgenti più luminose del cielo nella banda dei raggi gamma. È anche una delle più vicine, motivo per cui è una fra le più studiate dalla comunità scientifica che si occupa di astrofisica delle alte e altissime energie. Situata nella costellazione dell’Orsa Maggiorea circa 400 milioni di anni luce dalla Terra, fa parte di una sottoclasse di nuclei galattici attivi che gli addetti ai lavori chiamano blazar: galassie che ospitano al centro un buco nero supermassiccio che alimenta potenti getti relativistici orientati lungo la nostra linea di vista. Questa particolare configurazione rende le sorgenti estremamente luminose e variabili alle alte e altissime energie, trasformandole in laboratori naturali per lo studio dei processi fisici più estremi dell’universo.
Il segnale rivelato da Astri-1 è associato all’emissione di un flare – un’improvvisa e intensa emissione di energia – da parte del buco nero ed è coerente con l’elevato stato di attività della sorgente segnalato nelle stesse ore da altri osservatori per raggi gamma, tra cui Lhaaso (ATel #17535), Veritas (ATel #17594) e i due telescopi Cherenkov di piccola taglia dell’osservatorio Ondřejov (ATel #17597). Il flusso di raggi gamma rilevato è risultato pari a circa 2,3 volte quello della Nebulosa del Granchio, sorgente di riferimento del cielo gamma, che il telescopio ha già osservato in passato.
«Attivati da un ATel di Veritas, che indicava che Markarian 421 fosse in flare, Astri-1 ha iniziato una campagna osservativa la notte tra il 14 e il 15 gennaio», racconta a Media Inaf Fabio Pintore, ricercatore all’Inaf Iasf di Palermo e componente del gruppo che si è occupato dell’analisi preliminare dei dati. «I tre osservatori al sito – Silvia Crestan, Camilla Quartiroli e Alan Sunny – hanno profuso un grande impegno per consentire di accumulare fino a due ore e mezza di dati della sorgente in condizioni di visibilità ottimali. Dati che, con grande efficienza del sistema di processamento e archiviazione, sono stati trasferiti nel data center di Roma alla fine della notte osservativa».
«In questi casi», continua il ricercatore, «la velocità è cruciale e tutto il sistema Astri – dall’acquisizione fino all’analisi dei dati, ottimizzato grazie a un grande sforzo collettivo della comunità Astri – ha funzionato alla perfezione. I dati sono stati immediatamente presi in carico da Saverio Lombardi e dal gruppo che si occupa della riduzione dei dati e dell’analisi scientifica preliminare, che sul finire della mattinata aveva già ottenuto primi risultati. Astri-1 ha confermato che la sorgente era ancora in flare. Il suo flusso, infatti, era più del doppio, in un range di energia di riferimento che abbiamo scelto essere compreso tra 0.8 e 5 TeV (dove TeV, teraelettronvolt, è l’unità d’energia tipica della luce gamma di altissima energia), di quello della Crab Nebula, una sorgente molto brillante nel cielo gamma. Questo risultato mostra le eccellenti potenzialità sia dei singoli telescopi che dell’array Astri, prospettando un futuro ricco di soddisfazioni che ripaga dei tanti sforzi compiuti da tutti i gruppi di lavoro coinvolti nella progettazione hardware, software e nell’analisi dati».
L’analisi preliminare dei dati indica che il segnale è estremamente “solido” dal punto di vista scientifico: il livello di significatività statistica è infatti di 11 sigma, un valore che esclude che la rivelazione sia dovuta al caso o a rumori di fondo.
«Siamo felici che il telescopio Astri-1 abbia osservato la sua prima sorgente extragalattica», commenta Giovanni Pareschi, astrofisico dell’Inaf di Brera e principal investigator del progetto. «Si tratta di un risultato scientifico sicuramente di grande rilievo nel campo dell’astronomia gamma con telescopi Cherenkov, ottenuto da un gruppo per larga maggioranza italiano, con uno strumento interamente sviluppato da Inaf. Il singolo telescopio Astri-1, con cui è stata effettuata l’osservazione, ha una sensibilità di un fattore quasi tre superiore a quella di telescopi analoghi usati in passato, grazie al grande campo di vista e alla costante risoluzione angolare. Non vediamo l’ora di lavorare in stereoscopia con gli altri telescopi dell’Astri Mini- Array, cosa che avverrà già a partire dalla tarda primavera del 2026».
Plato, la missione dell’Agenzia spaziale europea destinata a scoprire esopianeti simili alla Terra, ha superato con successo una prima serie di test necessari per garantire che sia idoneo al lancio. In particolare, per verificare le sue capacità di resistere agli scossoni e alle intense vibrazioni che sperimenterà durante il lancio, posticipato ufficialmente al 2027, il veicolo spaziale è stato sottoposto ai test di vibrazione.
Plato è arrivata a Estec, nei Paesi Bassi, all’inizio di settembre 2025, e dopo il completamento dell’assemblaggio dello schermo solare e dei pannelli fotovoltaici il payload era pronto per la fase dei test ambientali. I test di vibrazione si sono svolti in tre fasi distinte. Nel corso della prima fase il veicolo spaziale è stato montato su un quad shaker e scosso energicamente rispetto all’asse Z (su e giù, come possiamo vedere nel video qui sotto, pubblicato ieri dall’Esa). Nelle altre due fasi è stato sottoposto allo stesso test tramite uno shaker “laterale”, e scosso lateralmente avanti e indietro in due direzioni perpendicolari (assi X e Y). Ogni prova è durata circa un minuto, durante il quale la frequenza delle oscillazioni è stata gradualmente aumentata da 5 a 100 oscillazioni al secondo (hertz). A frequenze più elevate non siamo più in grado di percepire il movimento, ma soltanto il rombo interno del veicolo spaziale causato dalle rapide vibrazioni. Il suono si intensifica in questo caso “a ondate”, quando vengono raggiunte le frequenze di risonanza.
Ricordiamo che i primi due minuti di un volo spaziale sono i più critici, poiché in questa fase il payload deve sopportare le vibrazioni estreme del lancio. Sottoponendo in anticipo il veicolo a questi stress, gli ingegneri si assicurano che nessun componente hardware venga danneggiato durante il lancio a causa di questo stress.
Dopo i test di vibrazione, il payload è stato collocato all’interno della camera di test acustici e bombardato da un suono ad altissima intensità, paragonabile a quello che sperimenterà durante il decollo. Anche questo test è andato come previsto. A breve la sonda verrà spostata nel Large Space Simulator – la più grande camera a vuoto d’Europa, sempre a Estec – per verificare che possa resistere alle temperature estreme e al vuoto dello spazio.
Entro la fine dell’anno Plato dovrà essere pronta al lancio, pianificato da Ariane Space per gennaio 2027.
Out of This World Discoveries: Space Station Research in 2025
As Earth completed its orbit around the Sun to close out 2025, the International Space Station circled our planet more than 5,800 times. Serving as humanity’s unique laboratory in space, the station has hosted thousands of experiments and technology demonstrations, advancing science in ways that cannot be replicated on Earth.
In 2025 alone, more than 750 experiments supported exploration missions, improved life on Earth, and opened commercial opportunities in low Earth orbit. The space station continues to drive innovation by enabling human exploration of the Moon and Mars, transforming medical research, deepening our understanding of the universe, and fostering a growing commercial economy.
Read through just a handful of 2025’s innovative research achievements from the orbiting laboratory.
25 Years of humans researching in orbit

On Nov. 2, 2025, humanity reached a milestone of cosmic proportions: 25 years of continuous human presence aboard the International Space Station. Since the first crew arrived on Nov. 2, 2000, NASA and its partners from around the world have conducted more than 4,000 research investigations and technology demonstrations. More than 290 people from 26 countries have visited the space station, where continuous human presence enables research that surpasses the capabilities of satellites and autonomous platforms. The space station’s unique microgravity environment, paired with crew operations, continues to unlock discoveries and push the boundaries of humanity’s curiosity and innovation.

Research aboard the International Space Station helped inform the development of a newly FDA-approved injectable medication used to treat several types of early-stage cancers. The research yielded early insights into the structure and size of particles needed to develop the medication through protein crystal growth experiments. This new delivery method promises to lower costs and significantly reduce treatment time for patients and healthcare providers, while maintaining drug efficiency. Microgravity research can produce higher-quality, medically relevant crystals than Earth-based labs, enabling these types of medical advances. These developments showcase how space station research can drive innovation, improve lives, and foster commercial opportunities.

Eight medical implants designed to support nerve regeneration were successfully 3D printed aboard the International Space Station for preclinical trials on Earth. When nerve damage occurs, these types of implants are designed to improve blood flow and enable targeted drug delivery. Printing in microgravity can prevent particle settling, resulting in more uniform and stable structures. In-space manufacturing is helping to advance medical treatments and other technologies while also enabling astronauts to print devices and tools on demand during future missions.

A solar coronagraph aboard the International Space Station captured its first unique images detailing the Sun’s outer atmosphere while measuring solar wind temperature and speed. The instrument blocks the Sun’s bright light to reveal its faint outer atmosphere, or corona, where solar wind originates. Earlier experiments focused on the corona’s density, but this new device enables the study of what heats and accelerates the solar wind, offering a more complete picture of how energy moves through the Sun’s atmosphere. These observations help researchers understand how solar activity affects Earth and space-based technology, such as satellites, communications networks, and power systems.
NASA astronaut Butch Wilmore works outside the International Space Station on Jan. 30, 2025, during a five-hour and 26-minute spacewalk.
NASA
NASA astronaut Butch Wilmore collected microbiological samples during a spacewalk outside the International Space Station. Samples were taken near the life support system vents to see if the orbital complex releases microorganisms. This experiment helps researchers examine if and how these microorganisms survive and reproduce in the harsh space environment, as well as how they may behave at destinations such as the Moon and Mars. After returning to Earth, the samples underwent DNA extraction and sequencing. Another round of collections is planned for future spacewalks. The data could help determine whether changes are needed on crewed spacecraft and spacesuits to reduce biocontamination during missions to explore destinations where life may exist now or in the past.

Eight medical implants designed to support nerve regeneration were successfully 3D printed aboard the International Space Station for preclinical trials on Earth. When nerve damage occurs, these types of implants are designed to improve blood flow and enable targeted drug delivery. Printing in microgravity can prevent particle settling, resulting in more uniform and stable structures. In-space manufacturing is helping to advance medical treatments and other technologies while also enabling astronauts to print devices and tools on demand during future missions.

A solar coronagraph aboard the International Space Station captured its first unique images detailing the Sun’s outer atmosphere while measuring solar wind temperature and speed. The instrument blocks the Sun’s bright light to reveal its faint outer atmosphere, or corona, where solar wind originates. Earlier experiments focused on the corona’s density, but this new device enables the study of what heats and accelerates the solar wind, offering a more complete picture of how energy moves through the Sun’s atmosphere. These observations help researchers understand how solar activity affects Earth and space-based technology, such as satellites, communications networks, and power systems.

NASA astronaut Butch Wilmore collected microbiological samples during a spacewalk outside the International Space Station. Samples were taken near the life support system vents to see if the orbital complex releases microorganisms. This experiment helps researchers examine if and how these microorganisms survive and reproduce in the harsh space environment, as well as how they may behave at destinations such as the Moon and Mars. After returning to Earth, the samples underwent DNA extraction and sequencing. Another round of collections is planned for future spacewalks. The data could help determine whether changes are needed on crewed spacecraft and spacesuits to reduce biocontamination during missions to explore destinations where life may exist now or in the past.

NASA’s Crawler-transporter 2 moves toward the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Friday, Jan. 9, 2026. The crawler will transport NASA’s SLS (Space Launch System) rocket with the Orion spacecraft to Launch Complex 39B ahead of the Artemis II launch which will journey Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialist Christina Koch from NASA, and Mission Specialist Jeremy Hansen from the CSA (Canadian Space Agency), around the Moon and back to Earth no later than April 2026.
The crawler-transporters have carried the load of taking rockets and spacecraft to the launch pad for more than 50 years at NASA’s Kennedy Space Center in Florida. Each the size of a baseball infield and powered by locomotive and large electrical power generator engines, the crawler-transporters stand ready to keep up the work for the next generation of launch vehicles to lift astronauts into space; Crawler-transporter 2 in particular is integral to the Artemis missions.

While this eerie NASA Hubble Space Telescope image may look ghostly, it’s actually full of new life. Lupus 3 is a star-forming cloud about 500 light-years away in the constellation Scorpius.
White wisps of gas swirl throughout the region, and in the lower-left corner resides a dark dust cloud. Bright T Tauri stars shine at the left, bottom right, and upper center, while other young stellar objects dot the image.
T Tauri stars are actively forming stars in a specific stage of formation. In this stage, the enveloping gas and dust dissipates from radiation and stellar winds, or outflows of particles from the emerging star. T Tauri stars are typically less than 10 million years old and vary in brightness both randomly and periodically due to the environment and nature of a forming star. The random variations may be due to instabilities in the accretion disk of dust and gas around the star, material from that disk falling onto the star and being consumed, and flares on the star’s surface. The more regular, periodic changes may be caused by giant sunspots rotating in and out of view.
T Tauri stars are in the process of contracting under the force of gravity as they become main sequence stars which fuse hydrogen to helium in their cores. Studying these stars can help astronomers better understand the star formation process.

Il telescopio spaziale James Webb della Nasa continua a battere primati, rivelando il più grande flusso di gas surriscaldato finora conosciuto nell’universo, espulso da una galassia chiamata VV 340a. La scoperta, realizzata da un team dell’Università della California a Irvine, è stata pubblicata la scorsa settimana sulla rivista Science.
Si tratta di una galassia che erutta gas da entrambi i lati sotto forma di due nebulose allungate, un fenomeno prodotto dall’attività di un buco nero supermassiccio situato nel suo nucleo. Analizzando i dati del telescopio Webb, il team ha scoperto che ciascuna nebulosa si estende per almeno tre kiloparsec (un parsec equivale a circa 30mila miliardi di chilometri). Nella maggior parte delle galassie, questo tipo di gas altamente energetico resta confinato entro poche decine di parsec dal buco nero centrale. In VV 340a, invece, raggiunge distanze superiori di almeno un fattore 30.

Le osservazioni nelle onde radio condotte con il Karl G. Jansky Very Large Array, vicino a San Agustin, nel New Mexico (Usa), hanno rilevato la presenza di una coppia di getti di plasma su larga scala che emergono dai due lati della galassia. Gli astronomi sanno che tali getti, capaci di energizzare gas surriscaldato ed espellere materiale dalla galassia, si formano quando temperature estreme e intensi campi magnetici accompagnano il gas che precipita nel buco nero supermassiccio attivo. Una volta espulsi, i getti disegnano una struttura elicoidale, segno di un fenomeno noto come “precessione del getto” che descrive il cambiamento del suo orientamento nel tempo, in modo simile all’oscillazione di una trottola in rotazione.
Il team suggerisce che, propagandosi verso l’esterno, i getti si accoppino con il materiale della galassia ospite, spingendolo lontano dal nucleo ed eccitandolo fino a stati altamente energetici. L’energia coinvolta è enorme, equivalente all’esplosione di dieci miliardi di miliardi di bombe all’idrogeno ogni secondo. In questo processo si forma il cosiddetto gas a linee coronali, un plasma caldo e altamente ionizzato che è quasi sempre associato alle regioni interne dei buchi neri supermassicci attivi e che solo raramente viene osservato al di fuori delle galassie.
Le osservazioni effettuate dalle Hawaii con il telescopio Keck II hanno inoltre permesso di individuare una quantità ancora maggiore di gas, che si estende fino a 15 kiloparsec (50mila anni luce) dal buco nero. Secondo gli autori, questo gas più freddo rappresenta una sorta di “documento fossile” della storia dell’interazione tra i getti e la galassia, residuo di precedenti episodi di espulsione di materiale dal nucleo.
La combinazione dei dati raccolti da diversi strumenti – tra cui, appunto, il telescopio spaziale Webb e il Keck II – ha così consentito di studiare la struttura di gas coronale più estesa e coerente mai osservata finora. Le stime indicano che VV 340a sta perdendo una quantità di gas sufficiente a formare ogni anno circa 19 stelle come il Sole, un processo che limita in modo significativo la formazione stellare nella galassia, riscaldando e rimuovendo il materiale necessario alla nascita di nuove stelle.
Il prossimo passo per i ricercatori sarà quello di studiare altre galassie simili, per verificare se fenomeni analoghi siano comuni e per comprendere meglio come galassie come la Via Lattea potrebbero evolversi nel tempo.
At about 800 kilometers (500 miles) east of New Zealand’s South Island, the sparsely populated Chatham Islands are rugged, remote, and often inconspicuous. In January 2026, however, a ring of bright green and blue swirls in the ocean put a natural spotlight on the far-flung specks of land.
A bloom of phytoplankton—tiny photosynthetic organisms that become visible to satellites when their numbers explode—encircled the Chatham Islands in austral summer. Surface currents and eddies carried the floating organisms into intricate wisps and swirls. The VIIRS (Visible Infrared Imaging Radiometer Suite) on the NOAA-20 satellite captured this image of the display on January 10, 2026.
The Chatham Islands sit on the Chatham Rise, an underwater plateau that extends eastward from the South Island of New Zealand. The top of the rise is relatively shallow and separates areas of deeper water to the north and south. These seafloor contours make blooms common along the Chatham Rise, where cold, nutrient-rich currents from the Antarctic and warm, nutrient-poor water from the subtropics converge. The well-mixed water, coupled with long daylight hours, can boost phytoplankton populations.
With phytoplankton at the base of the food web, the waters around the Chatham Islands support productive fisheries, with valuable species such as pāua, rock lobster, and blue cod. The region is also home to an array of marine mammals, including five seal species and 25 whale and dolphin species. Amid this abundance, however, the islands are a hotspot for whale and dolphin strandings, in which hundreds of animals are sometimes beached.

NASA’s SpaceX Crew-11 Wraps Up Space Station Science
NASA’s SpaceX Crew-11 mission with agency astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov returned to Earth after a long-duration mission aboard the International Space Station.
During their stay, Cardman, Fincke, and Yui contributed more than 850 hours of research to help prepare humanity for the return to the Moon and future missions to Mars, while improving life back on Earth.
Here’s a glimpse into the science completed during the Crew-11 mission:
Bolstering bone resilience
NASA astronaut Zena Cardman works with bone stem cells aboard the International Space Station to improve our understanding of how bone loss occurs during spaceflight. Studying bone cell activity in microgravity could help researchers learn how to control bone loss to protect astronauts’ bone density during future long-duration space missions and inform treatments for diseases like osteoporosis on Earth.
JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui photographs the Earth from the International Space Station’s cupola. For more than 40 years, astronauts have used hand-held cameras to capture millions of images documenting Earth’s geographic features, weather patterns, urban growth, changes to its surface, and the impacts of natural disasters such as hurricanes and floods.
Astronauts also use the cupola and other viewports aboard the space station to gaze into the cosmos without Earth’s atmospheric interference. Just as viewing Earth from 250 miles above provides a new perspective on our home planet, looking out into the stars from the orbiting laboratory offers a clearer view of our universe.
Space catch
NASA astronaut Mike Fincke poses aboard the International Space Station with a new device designed to test an inflatable capture bag’s ability to open, close, and stay airtight in microgravity. This technology could be used to remove space debris from orbit, protecting future spacecraft and crew members. It also may enable trapping samples during exploration missions and support the capture and mining of small asteroids.
NASA astronaut Mike Fincke wears a temperature-monitoring headband that tracks how the human body regulates its core temperature during spaceflight. Adjusting to living and working aboard the International Space Station can influence human temperature regulation. This headband provides an easy, non-invasive way to collect temperature data while astronauts conduct their daily activities. The sensor is also being tested on Earth and may help prevent hyperthermia in people working in high-temperature environments.
JAXA’s (Japan Aerospace Exploration Agency) new cargo resupply spacecraft, HTV-X1, is shown after being captured by the International Space Station’s Canadarm2 robotic arm during the Crew-11 mission. The spacecraft launched from Tanegashima Space Center on Oct. 26, 2025, delivering approximately 12,800 pounds of science, supplies, and hardware to the orbital complex. New cargo spacecraft expand the station’s capability to support more research and receive critical supplies.
Making nutrients on demand

Two retired U.S. Air Force F-15 jets have joined the flight research fleet at NASA’s Armstrong Flight Research Center in Edwards, California, transitioning from military service to a new role enabling breakthrough advancements in aerospace.
The F-15s will support supersonic flight research for NASA’s Flight Demonstrations and Capabilities project, including testing for the Quesst mission’s X-59 quiet supersonic research aircraft. One of the aircraft will return to the air as an active NASA research aircraft. The second will be used for parts to support long-term fleet sustainment.
“These two aircraft will enable successful data collection and chase plane capabilities for the X-59 through the life of the Low Boom Flight Demonstrator project” said Troy Asher, director for flight operations at NASA Armstrong. “They will also enable us to resume operations with various external partners, including the Department of War and commercial aviation companies.”
The aircraft came from the Oregon Air National Guard’s 173rd Fighter Wing at Kingsley Field. After completing their final flights with the Air Force, the two aircraft arrived at NASA Armstrong Dec. 22, 2025.
“NASA has been flying F-15s since some of the earliest models came out in the early 1970s,” Asher said. “Dozens of scientific experiments have been flown over the decades on NASA’s F-15s and have made a significant contribution to aeronautics and high-speed flight research.”
The F-15s allow NASA to operate in high-speed, high-altitude flight-testing environments. The aircraft can carry experimental hardware externally – under its wings or slung under the center – and can be modified to support flight research.
Now that these aircraft have joined NASA’s fleet, the team at Armstrong can modify their software, systems, and flight controls to suit mission needs. The F-15’s ground clearance allows researchers to install instruments and experiments that would not fit beneath many other aircraft.
NASA has already been operating two F-15s modified so their pilots can operate safely at up to 60,000 feet, the top of the flight envelop for the X-59, which will cruise at 55,000 feet. The new F-15 that will fly for NASA will receive the same modification, allowing for operations at altitudes most standard aircraft cannot reach. The combination of capability, capacity, and adaptability makes the F-15s uniquely suited for flight research at NASA Armstrong.
“The priority is for them to successfully support the X-59 through completion of that mission,” Asher said. “And over the longer term, these aircraft will help position NASA to continue supporting advanced aeronautics research and partnerships.”

Two retired U.S. Air Force F-15 jets have joined the flight research fleet at NASA’s Armstrong Flight Research Center in Edwards, California, transitioning from military service to a new role enabling breakthrough advancements in aerospace.
The F-15s will support supersonic flight research for NASA’s Flight Demonstrations and Capabilities project, including testing for the Quesst mission’s X-59 quiet supersonic research aircraft. One of the aircraft will return to the air as an active NASA research aircraft. The second will be used for parts to support long-term fleet sustainment.
“These two aircraft will enable successful data collection and chase plane capabilities for the X-59 through the life of the Low Boom Flight Demonstrator project” said Troy Asher, director for flight operations at NASA Armstrong. “They will also enable us to resume operations with various external partners, including the Department of War and commercial aviation companies.”
The aircraft came from the Oregon Air National Guard’s 173rd Fighter Wing at Kingsley Field. After completing their final flights with the Air Force, the two aircraft arrived at NASA Armstrong Dec. 22, 2025.
“NASA has been flying F-15s since some of the earliest models came out in the early 1970s,” Asher said. “Dozens of scientific experiments have been flown over the decades on NASA’s F-15s and have made a significant contribution to aeronautics and high-speed flight research.”
The F-15s allow NASA to operate in high-speed, high-altitude flight-testing environments. The aircraft can carry experimental hardware externally – under its wings or slung under the center – and can be modified to support flight research.
Now that these aircraft have joined NASA’s fleet, the team at Armstrong can modify their software, systems, and flight controls to suit mission needs. The F-15’s ground clearance allows researchers to install instruments and experiments that would not fit beneath many other aircraft.
NASA has already been operating two F-15s modified so their pilots can operate safely at up to 60,000 feet, the top of the flight envelop for the X-59, which will cruise at 55,000 feet. The new F-15 that will fly for NASA will receive the same modification, allowing for operations at altitudes most standard aircraft cannot reach. The combination of capability, capacity, and adaptability makes the F-15s uniquely suited for flight research at NASA Armstrong.
“The priority is for them to successfully support the X-59 through completion of that mission,” Asher said. “And over the longer term, these aircraft will help position NASA to continue supporting advanced aeronautics research and partnerships.”
«Alle 3:41 del mattino, ora della costa orientale [le 9:41 ora italiana di oggi, ndr], la navicella Dragon Endeavor di SpaceX è ammarata con successo al largo della costa della California in condizioni meteorologiche ottimali. Questa missione ha riportato a casa sani e salvi i membri dell’equipaggio della Crew-11. Gli astronauti della Nasa Zena Cardman e Michael Fincke, l’astronauta della Jaxa Kimiya Yui e il cosmonauta della Roscosmos Oleg Platonov sono tutti in buona salute e di ottimo umore. Tutti i membri dell’equipaggio sono attualmente sottoposti alla consueta valutazione medica post-ammaraggio. Il membro dell’equipaggio che destava preoccupazione sta bene. Condivideremo aggiornamenti sul loro stato di salute non appena sarà opportuno farlo».

Comincia così la conferenza stampa tenuta questa mattina alla Nasa riguardo il rientro anticipato della Crew-11 dalla Stazione spaziale internazionale (Iss), dovuto a un problema medico di uno dei quattro membri dell’equipaggio. A parlare è l’amministratore dell’agenzia Jared Isaacman, che sottolinea come la Nasa fosse pronta a questa evenienza nonostante fosse la prima volta nella storia e come abbia saputo gestirla al meglio.
La permanenza della Crew-11 alla Iss è durata circa cinque mesi (167 giorni), durante i quali gli astronauti hanno dedicato oltre 850 ore a esperimenti e studi scientifici, tra cui ricerche sulla perdita ossea in microgravità e lo stoccaggio a lungo termine di fluidi criogenici nello spazio. Esperimenti che – sottolinea l’amministratore – avrebbero applicazioni dirette in campo medico e industriale e che hanno migliorato la nostra comprensione dei voli spaziali di lunga durata. I quattro astronauti si trovano ora in una clinica nella periferia di San Diego, in California, dove trascorreranno la notte per poi fare ritorno a Houston venerdì.

Il prossimo mese vedrà due appuntamenti importanti per la Nasa e, più in generale, per il volo umano. Il 6 febbraio si apre la finestra di lancio di Artemis II, la missione che porterà quattro astronauti in orbita attorno alla Luna per la prima volta dopo le missioni Apollo. Si tratta del primo volo con equipaggio del razzo Space Launch System (Sls) e della navicella spaziale Orion. In questi giorni la Nasa sta preparando il trasferimento del veicolo completamente assemblato alla piattaforma di lancio 39B del Kennedy Space Center in Florida, che avverrà non prima di sabato 17 gennaio 2026. A seguire, il 15 febbraio si apre la finestra di lancio della Crew-12 per la Stazione spaziale internazionale, che vedrà fra i membri dell’equipaggio l’astronauta francese Sophie Adenot dell’Agenzia spaziale europea (Esa).

Come Davide contro il gigante Golia. Ma in questa storia cosmica il ruolo di Davide spetta a Marte, che pur essendo grande la metà della Terra e con una massa pari a circa un decimo, esercita un’azione sorprendente sul clima del nostro pianeta e persino sulle ere glaciali. Piccolo, lontano, apparentemente irrilevante. E invece capace di lasciare un segno profondo.
Confronto tra le dimensioni della Terra e di Marte. Crediti: Earth: Nasa/Apollo 17 Crew; Mars: Esa/Mps/Upd/Lam/Iaa/Rssd/Inta/Upm/Dasp/Ida
A mostrare tale fenomeno è uno studio, guidato dall’Università della California a Riverside e pubblicato il mese scorso sulla rivista Publications of the Astronomical Society of the Pacific, nel quale gli autori hanno affrontato alcuni dubbi su recenti ricerche che collegano gli antichi modelli climatici della Terra alle spinte gravitazionali di Marte. Queste ricerche suggeriscono che alcuni dei cicli climatici testimoniati dagli strati sedimentari presenti sul fondo dell’oceano siano influenzati dal Pianeta rosso, nonostante la sua distanza dalla Terra e le sue dimensioni relativamente contenute.
«Sapevo che Marte ha un certo effetto sulla Terra, ma credevo fosse minimo», dice Stephen Kane, professore di astrofisica planetaria all’Uc Riverside. «Pensavo che la sua influenza gravitazionale fosse troppo piccola per essere facilmente osservabile nella storia geologica della Terra, ma ho comunque voluto pro0vare a verificare le mie ipotesi».
Per farlo, Kane ha realizzato sofisticate simulazioni al computer del Sistema solare, analizzando l’evoluzione a lungo termine dell’orbita terrestre e della sua inclinazione. Il punto chiave è risultato essere nei cicli di Milankovitch, lenti cambiamenti dell’orbita e dell’asse terrestre che regolano come e quanta luce solare raggiunge il nostro pianeta su scale di decine o centinaia di migliaia di anni. Agendo come “cronometri” per le ere glaciali e i periodi interglaciali, questi cicli sono fondamentali per spiegare l’alternanza tra climi freddi e caldi su scale temporali di migliaia di anni.
Nei suoi 4,5 miliardi di anni di storia, la Terra ha attraversato almeno cinque grandi ere glaciali – l’ultima è iniziata circa 2,6 milioni di anni fa. Tra i cicli di Milankovitch, viene tradizionalmente ritenuto importante quello di circa 430mila anni dominato dall’influenza gravitazionale di Venere e Giove, che modifica l’eccentricità dell’orbita terrestre rendendola più o meno ellittica. In questo lasso di tempo, la traiettoria della Terra attorno al Sole oscilla gradualmente da una forma quasi circolare a una più allungata, per poi tornare indietro. Un cambiamento che incide sulla quantità di energia solare che raggiunge il pianeta e che può influenzare l’avanzata o il ritiro delle calotte glaciali.
Nelle simulazioni di Kane, questo ciclo rimane invariato anche eliminando il Pianeta rosso. Ma qui arriva la sorpresa: senza Marte scompaiono completamente altri due cicli cruciali – uno di circa 100mila anni e uno di circa 2,3–2,4 milioni di anni – ben visibili nei sedimenti oceanici e legati alle grandi transizioni climatiche. «Quando si rimuove Marte, quei cicli svaniscono», dice Kane. «E se si aumenta la massa di Marte diventano sempre più brevi, perché Marte ha un effetto maggiore».

Questi cicli fanno sì che Marte contribuisca in modo diretto a modulare tre aspetti: la forma circolare o allungata dell’orbita terrestre (la sua eccentricità, appunto), il momento in cui la Terra si avvicina maggiormente al Sole e l’inclinazione del suo asse di rotazione (la sua inclinazione). Tutti parametri che incidono sulla distribuzione dell’energia solare sul nostro pianeta, e quindi sull’avanzata o il ritiro delle calotte glaciali.
Un risultato inatteso del nuovo studio riguarda proprio l’inclinazione terrestre. Attualmente la Terra è inclinata di circa 23,5 gradi, angolo che cambia leggermente nel tempo. Un Marte più massiccio rallenterebbe la velocità con cui questa inclinazione varia, esercitando un effetto stabilizzante sul clima.
«Più un pianeta è vicino al Sole, più è dominato dalla sua gravità. Orbitando più lontano dal Sole rispetto al nostro pianeta, Marte ha un effetto gravitazionale sulla Terra maggiore di quello che avrebbe se fosse più vicino. Incide, insomma, ben oltre le attese, considerando le sue dimensioni», spiega Kane.
Paradossalmente, un pianeta piccolo ma lontano dal Sole “pesa” dunque più di quanto ci si aspetterebbe nel delicato equilibrio del Sistema solare interno. E le implicazioni vanno oltre la Terra. Lo studio suggerisce che anche pianeti relativamente piccoli, posti nelle regioni esterne di altri sistemi planetari, potrebbero influenzare il clima e la stabilità di mondi potenzialmente abitabili.
«Senza Marte, l’orbita terrestre sarebbe priva di importanti cicli climatici», conclude Kane. «Come sarebbero gli esseri umani e gli altri animali se il Pianeta rosso non esistesse?»
Un nuovo studio dell’Istituto nazionale di astrofisica (Inaf) fornisce la mappa più dettagliata mai realizzata della distribuzione e della composizione delle argille sulla superficie di Marte, offrendo nuove chiavi di lettura sull’evoluzione geologica del pianeta, sul ruolo dell’acqua nel suo passato e sulla sua potenziale abitabilità.
Il lavoro, pubblicato sulla rivista Journal of Geophysical Research: Planets, si basa su quasi 1500 osservazioni condotte su scala globale e acquisite dallo spettrometro Crism (Compact Reconnaissance Imaging Spectrometer for Mars) a bordo del Mars Reconnaissance Orbiter della Nasa. Grazie a questa analisi è stato possibile estrarre e interpretare le firme spettrali nell’infrarosso delle argille presenti sulla superficie marziana.

La linea gialla delimita la grande dicotomia della crosta marziana, che segna la zona di transizione dagli antichi altopiani alle pianure più giovani. La linea rossa tratteggiata circonda l’area dominata dall’Olympus Mons e dal Tharsis Rise. Le stelle rosa e verdi indicano le posizioni dei lander e dei rover passati, presenti e futuri. I riquadri bianchi segnalano le aree ingrandite mostrate nelle Fig. 2–3. Crediti: J. Brossier/Inaf (Brossier et al. 2026)
Le argille marziane rappresentano una traccia diretta dell’acqua che un tempo ha modellato il quarto pianeta del Sistema solare e i luoghi in cui la vita avrebbe potuto svilupparsi. Alcune regioni del Pianeta rosso sono infatti considerate ambienti privilegiati per la possibile conservazione di biofirme; per questo motivo, la loro distribuzione e la composizione mineralogica costituiscono elementi chiave sia per la ricostruzione degli antichi ambienti acquosi di Marte sia per la selezione dei siti di atterraggio delle future missioni di esplorazione.

Brossier/Inaf (Brossier et al. 2026)
«Abbiamo realizzato una mappa globale, messa a disposizione della comunità “marziana” internazionale, che mostra la distribuzione dei principali minerali idratati presenti su Marte, tra cui argille, solfati, cloriti e carbonati», spiega Jeremy Brossier, ricercatore dell’Inaf e primo autore dell’articolo. «Il nuovo studio fornisce inoltre una caratterizzazione dettagliata dei minerali argillosi, dalle fasi ricche di ferro (nontroniti) a quelle ricche di magnesio (saponiti), includendo anche composizioni intermedie come vermiculiti e ferrosaponiti. Questa ampia diversità mineralogica riflette una storia geochimica lunga e complessa del pianeta, legata a diverse condizioni di formazione e alterazione in presenza di acqua».
Per ottenere questi risultati, il team ha sviluppato nuovi metodi per ridurre il cosiddetto “rumore” nei dati spettrali, migliorando in modo significativo le capacità di identificare e distinguere le firme delle argille e di altri minerali. È stato inoltre implementato un approccio innovativo per estrarre dettagli dagli spettri, consentendo di separare con maggiore precisione i segnali associati alle argille ricche di ferro da quelle ricche di magnesio.

In questa regione si trova il cratere Jezero, attualmente esplorato dal rover Perseverance della Nasa, operativo su Marte dal 2021. Crediti: J. Brossier/Inaf (Brossier et al. 2026)
I risultati mostrano variazioni spaziali significative nella mineralogia argillosa di Marte: le nontroniti, ricche di ferro, dominano nella regione di Mawrth Vallis, mentre le saponiti, ricche di magnesio, sono concentrate soprattutto nelle aree di Nili Fossae e di Libya Monter. Oxia Planum, il sito di atterraggio del rover europeo Rosalind Franklin della missione ExoMars dell’Agenzia spaziale europea (Esa), ospita invece argille di composizione più intermedia, tra cui vermiculiti e ferrosaponiti. Queste caratteristiche rendono Oxia Planum un’area particolarmente promettente per lo studio degli antichi ambienti acquosi e per la ricerca di possibili biofirme.
Proprio per questo, «lo studio si inserisce direttamente nel contesto della missione ExoMars, che prevede l’esplorazione del suolo marziano a partire dal 2030. In questo scenario, l’Inaf svolge un ruolo di primo piano nello sviluppo dello strumento Ma_Miss (Mars Multispectral Imager for Subsurface Studies), uno spettrometro progettato per analizzare rocce e suoli del sottosuolo marziano e ricostruirne la storia geologica e ambientale», conclude il ricercatore.

NASA’s SpaceX Crew-11 mission safely splashed down early Thursday morning in the Pacific Ocean off the coast of San Diego, concluding a more than five-month mission aboard the International Space Station.
NASA astronauts Zena Cardman and Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, and Roscosmos cosmonaut Oleg Platonov returned to Earth at 12:41 a.m. PST. Teams aboard SpaceX recovery vessels retrieved the spacecraft and its crew shortly after landing.
“I couldn’t be prouder of our astronauts and the teams on the ground at NASA, SpaceX, and across our international partnerships,” said NASA Administrator Jared Isaacman. “Their professionalism and focus kept the mission on track, even with an adjusted timeline. Crew-11 completed more than 140 science experiments that advance human exploration. Missions like Crew-11 demonstrate the capability inherent in America’s space program—our ability to bring astronauts home as needed, launch new crews quickly, and continue pushing forward on human spaceflight as we prepare for our historic Artemis II mission, from low Earth orbit to the Moon and ultimately Mars.”
Crew-11 returned home about a month earlier than planned because of a medical concern teams are monitoring with one of the crew members, who remains stable. Due to medical privacy, it is not appropriate for NASA to share more details about the crew member. Prior to return, NASA previously coordinated for all four crew members to be transported to a local hospital for additional evaluation, taking advantage of medical resources on Earth to provide the best care possible.
Following the planned overnight hospital stay, the crew members will return to NASA’s Johnson Space Center in Houston and undergo standard postflight reconditioning and evaluations.
The Crew-11 mission lifted off at 11:43 a.m. EDT on Aug.1, 2025, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. About 15 hours later, the crew’s SpaceX Dragon spacecraft docked to the orbital outpost at 1:27 a.m. CDT on Aug. 2.
During their 167-day mission, the four crew members traveled nearly 71 million miles and completed more than 2,670 orbits around Earth. The Crew-11 mission was Fincke’s fourth spaceflight, Yui’s second, and the first for Cardman and Platonov. Fincke has logged 549 days in space, ranking him fourth among all NASA astronauts for cumulative days in space.
Along the way, Crew-11 logged hundreds of hours of research, maintenance, and technology demonstrations. The crew members also celebrated the 25th anniversary of continuous human presence aboard the orbiting laboratory on Nov. 2, 2025. Research conducted aboard the space station advances scientific knowledge and demonstrates new technologies that enable us to prepare for human exploration of the Moon and Mars.

La prima cosa da sapere sui buchi neri è che si chiamano così perché qualunque cosa – materia o luce – attraversi il loro orizzonte degli eventi non può più uscire. La seconda cosa è che non tutto ciò che viene attirato da un buco nero incorre in questo destino. Prima di attraversare il punto di non ritorno definitivo – l’orizzonte degli eventi, appunto –, nei buchi neri in accrescimento il materiale in arrivo forma un disco che ruota attorno al buco nero. Da questo disco di accrescimento, occasionalmente e in determinate circostanze, quantità di materiale sorprendentemente grandi vengono nuovamente espulse nello spazio. Avviene sotto forma di venti a raggi X, oppure di getti relativistici di plasma. E la congiunzione non è un caso: secondo un nuovo studio pubblicato su Nature Astronomyuna modalità esclude l’altra.

Si tratterebbe della prima chiara prova osservativache questi due tipi di emissioni sono mutuamente esclusivi. Quando uno è attivo, l’altro scompare. Ma vediamoli meglio. I getti relativistici sono fasci di plasma stretti e concentrati che fuoriescono dai poli del buco nero a una velocità prossima a quella della luce, alimentati dai campi magnetici e dalla rotazione del buco nero. I venti di raggi X, invece, sono flussi più ampi e lenti di gas altamente ionizzato espulso dalla superficie del disco di accrescimento dalla radiazione e dalla pressione magnetica.
Nello studio, gli scienziati si sono concentrati su un sistema binario chiamato 4U 1630−472, formato da un buco nero con una massa circa dieci volte superiore a quella del Sole e da una stella compagna, dalla quale “ruba” materiale che riempie il suo disco di accrescimento e viene regolarmente espulso come vento o getto. Il sistema è stato monitorato per tre anni grazie alle osservazioni del telescopio a raggi X Nicer della Nasa, a bordo della Stazione Spaziale Internazionale, e del radiotelescopio MeerKat in Sudafrica. In questo periodo, il buco nero non ha mai prodotto contemporaneamente venti forti e getti potenti: quando il buco nero emette un getto di plasma ad alta velocità, il vento di raggi X si placa, e quando il vento riprende, il getto svanisce.
«In sistemi come 4U 1630-47, che accrescono materia a tassi compatibili con il regime standard di disco sottile, riteniamo che l’apparente mutua esclusività tra venti di disco e getti relativistici possa rappresentare un comportamento generale, piuttosto che una peculiarità di una singola sorgente», dice a Media InafFrancesco Carotenuto, ricercatore postdoc all’Inaf di Roma e coautore dello studio. «I nostri risultati suggeriscono che le diverse modalità di espulsione del materiale non co-esistano simultaneamente, ma tendano piuttosto ad alternarsi nel tempo, in diverse fasi di attività (chiamate outbursts) del sistema. Al contrario di molti altri sistemi noti, 4U 1630-47 ha mostrato varie fasi di outburst negli ultimi anni, che abbiamo seguito nella loro evoluzione con dense campagne osservative nella banda radio e nei raggi X».
Non un caso isolato, dunque, questo buco nero, ma l’espressione di una “regola” generale. E c’è di più: mentre i due meccanismi si alternano, la quantità di materiale in arrivo rimane pressocché costante, un po’ come se il buco nero fosse in grado di autoregolarsi. Getti e vento, infatti, trasportano quantità comparabili di massa ed energia, suggerendo che, mentre la forma del flusso in uscita cambia, la velocità totale del flusso rimane invariata.
«Una possibile spiegazione fisica è che la forma dominante dell’outflow sia regolata da cambiamenti nella configurazione del campo magnetico associato al plasma del disco di accrescimento, in particolare nelle regioni più interne del disco e nella sua interazione con il buco nero», spiega Carotenuto. «I risultati di simulazioni numeriche suggeriscono infatti che differenti configurazioni del campo magnetico possano dare origine in modo naturale a meccanismi di “lancio” o “espulsione” diversi. Le transizioni tra queste configurazioni potrebbero quindi permettere alla sorgente di passare da uno stato dominato da venti a uno dominato da getti, senza richiedere cambiamenti drastici nel tasso globale di accrescimento».
In breve, i buchi neri non si limitano a consumare materia, ma la gestiscono, decidendo se espellerla nello spazio sotto forma di getto concentrato o spazzarla via con venti violenti. L’equilibrio tra venti e getti svolge un ruolo fondamentale nel regolare la crescita dei buchi neri, e influenza anche la formazione delle stelle nelle regioni vicine e l’evoluzione delle galassie. Questo meccanismo, infatti, potrebbe non riguardare solo i buchi neri di massa stellare come quello del sistema studiato, ma anche i buchi neri supermassicci al centro delle galassie. L’unica condizione irrinunciabile è che si tratti di un buco nero in accrescimento.
«Il disco di accrescimento è infatti un elemento fondamentale per la produzione sia dei venti sia dei getti, e senza un disco questi meccanismi non possono operare», specifica Carotenuto. «I sistemi binari a raggi X, in cui un buco nero di massa stellare (di circa 10 masse solari) accresce materia da una stella compagna, sono particolarmente importanti perché evolvono su scale temporali relativamente brevi (nell’ordine di settimane o mesi). Questo ci permette di osservare direttamente i cambiamenti nei meccanismi di espulsione del materiale nel corso del tempo. È possibile che comportamenti simili avvengano anche attorno a buchi neri supermassicci nei nuclei galattici attivi, ma in quel caso le transizioni avverrebbero su tempi molto più lunghi, rendendole molto più difficili da osservare direttamente».

È scomparso lo scorso 12 gennaio 2026 a Firenze, all’età di 99 anni, Mario Rigutti, figura di riferimento dell’astrofisica italiana e protagonista del rinnovamento dell’Osservatorio astronomico di Capodimonte.
Mario Rigutti, 29 giugno 1979. Crediti: Inaf Capodimonte
Nato a Trieste nel 1926, Rigutti attraversò da giovanissimo gli anni difficili della guerra, mantenendo però intatta la passione per l’astronomia che lo avrebbe accompagnato per tutta la vita. Dopo gli studi tra Trieste e Firenze, si formò all’Osservatorio di Arcetri sotto la guida di Giorgio Abetti e Guglielmo Righini, distinguendosi per le sue ricerche sulla fotosfera solare e sulle bande molecolari del cianogeno. Negli anni Sessanta del secolo scorso, il suo percorso scientifico si aprì alla dimensione internazionale: prima al Dominion Observatory di Ottawa in Canada, poi all’Università di Berkeley in California dove entrò in contatto con alcuni dei protagonisti della fisica e dell’astrofisica solare del tempo. Fu protagonista di numerose spedizioni per l’osservazione di eclissi totali di Sole, contribuendo in modo decisivo alla conoscenza della corona solare. Fu in Canada (1963), in Grecia (1966), in Brasile (1966) e in Mauritania (1973). Da quest’ultima spedizione trasse ispirazione per il volume La scomaprsa del Sole (Gianinni 2014), un racconto di viaggio e di culture nuove e di scienza.
Nel 1969 approdò a Napoli come professore ordinario di astronomia all’Università Federico II e direttore degli osservatori di Capodimonte e di Teramo. A Napoli, la sua guida, durata fino al 1992, segnò una stagione di profonda trasformazione scientifica, culturale e infrastrutturale.
«A lui si deve una profonda trasformazione scientifica e infrastrutturale dell’istituto» commenta l’attuale direttore dell’Osservatorio di Capodimonte, Pietro Schipani «l’introduzione dell’indirizzo astrofisico all’Università di Napoli, la modernizzazione della strumentazione, la creazione del planetario didattico, dell’Auditorium e, nel 1991, del museo dell’Osservatorio. Anche gli attuali astronomi di Capodimonte devono qualcosa al prof. Rigutti».
Nella sua attività di ricerca, Mario Rigutti si è occupato degli strati esterni del Sole – fotosfera, cromosfera e corona – e dei fenomeni legati all’attività solare, come brillamenti e protuberanze. Tra il 1968 e il 1972 è stato membro della European Solar Research Organization e fino al 1973 chairman del Gruppo di lavoro per le eclissi totali di Sole dell’Unione astronomica internazionale. Autore di oltre 150 pubblicazioni scientifiche e instancabile divulgatore, Rigutti seppe parlare al grande pubblico con chiarezza e passione. Il suo libro Cento miliardi di stelle rimane un punto di riferimento per generazioni di lettori. Negli ultimi anni si dedicò anche alla narrativa e alla poesia, ottenendo numerosi riconoscimenti. Nel 2019 il Minor Planet Center gli ha dedicato il pianetino (33823) Mariorigutti, un tributo alla sua lunga vita spesa a osservare e raccontare l’universo.

Accanto alla scienza, coltivava l’arte del disegno a matita e un profondo amore per la musica classica che considerava una forma di armonia affine a quella del cosmo. Socio di numerose società scientifiche, Rigutti è stato presidente dell’Accademia di scienze fisiche e matematiche di Napoli nel 1991 e della Società astronomica italiana dal 1977 al 1981. È stato inoltre tra i fondatori e direttore del Giornale di astronomia, contribuendo in modo decisivo alla crescita della cultura astronomica nel nostro Paese. La comunità astronomica italiana perde un protagonista appassionato e generoso, un uomo capace di unire rigore scientifico, visione culturale e un profondo impegno civile nella diffusione del sapere.
Da dicembre 2021, quando il James Webb Space Telescope (Jwst) ha visto la prima luce a circa 1,5 milioni di chilometri dalla Terra, i ricercatori di tutto il mondo si interrogano sugli enigmatici puntini rossi che spiccano tra le galassie nelle immagini catturate dal telescopio. I cosiddetti little red dots (piccoli punti rossi) erano visibili quando l’universo aveva “solo” alcune centinaia di milioni di anni; circa un miliardo di anni dopo, però, sembrano essere scomparsi. Che cosa erano, dunque?
“I piccoli puntini rossi sono giovani buchi neri, cento volte meno massicci di quanto si pensasse in precedenza, avvolti in un bozzolo di gas, che stanno consumando per crescere. Questo processo genera un calore enorme, che traspare attraverso il bozzolo. Questa radiazione attraverso il bozzolo è ciò che conferisce ai piccoli puntini rossi il loro caratteristico colore rosso”, spiega Darach Watson. Crediti: Darach Watson/Jwst
Si è pensato fossero galassie massicce, abbastanza potenti da essere rilevate da Jwst 13 miliardi di anni dopo. Ma è molto strano che galassie così evolute fossero già presenti così presto nella storia cosmica. Ora, dopo due anni di analisi continua delle immagini con i piccoli punti rossi, i ricercatori del Cosmic Dawn Centre del Niels-Bohr Institute hanno trovato la spiegazione nel fenomeno più potente del nostro universo: i buchi neri.
«I piccoli punti rossi sono giovani buchi neri, cento volte meno massicci di quanto si credesse in precedenza, avvolti in un bozzolo di gas, che stanno consumando per ingrandirsi. Questo processo genera un calore enorme, che traspare attraverso il bozzolo. Questa radiazione attraverso il bozzolo è ciò che conferisce ai piccoli punti rossi il loro caratteristico colore rosso», afferma Darach Watson, ricercatore al Cosmic Dawn Center di Copenhagen e coautore dell’articolo che rivela la natura di questi oggetti, pubblicato oggi su Nature. «Sono molto meno massicci di quanto si credesse in precedenza, quindi non abbiamo bisogno di invocare tipologie di eventi completamente nuovi per spiegarli».
Attualmente sono noti centinaia di piccoli punti rossi. Sebbene siano tra i buchi neri più piccoli mai scoperti, hanno comunque una massa fino a 10 milioni di volte quella del Sole e un diametro di 10 milioni di chilometri.
I buchi neri inghiottono tutto ciò che si trova nelle loro vicinanze e crescono mentre lo divorano. Ma poiché l’orizzonte degli eventi dei buchi neri non è molto vasto, il gas in caduta si riscalda a temperature così elevate da brillare intensamente e rilasciare più energia di qualsiasi altro processo a noi noto. Questa intensa radiazione fa sì che gran parte della materia che il buco nero consuma venga espulsa.
La copertina dell’ultimo numero di Nature è dedicata a questa scoperta. Crediti: Darach Watson/Jwst
«Quando il gas cade verso un buco nero, si muove a spirale verso la superficie del buco nero, formando una sorta di disco o imbuto. Finisce per muoversi così velocemente e viene compresso così intensamente da generare temperature di milioni di gradi e illuminarsi intensamente. Ma solo una piccolissima quantità di gas viene inghiottita dal buco nero. La maggior parte viene espulsa dai poli durante la rotazione del buco nero. Ecco perché chiamiamo i buchi neri mangiatori disordinati», spiega Watson.
La nuova scoperta getta luce sulle fasi iniziali dell’evoluzione dei buchi neri e contribuisce a spiegare come, appena 700 milioni di anni dopo il Big Bang, potessero già esistere buchi neri supermassicci con masse fino a un miliardo di volte quella del Sole. «Abbiamo catturato i giovani buchi neri nel mezzo della loro rapida crescita, in una fase che non avevamo mai osservato prima. Il denso bozzolo di gas che li circonda fornisce il carburante di cui hanno bisogno per crescere molto rapidamente», conclude Watson.
«L’articolo propone un interessante scenario fisico per spiegare le proprietà osservative della nuova, inaspettata popolazione di nuclei galattici attivi distanti scoperta da Jwst, inclusi i little red dots, e sembrerebbe confermare che questa nuova popolazione tracci le prime, rapidissime fasi di accrescimento dei buchi neri supermassicci», commenta a Media InafRoberto Gilli, astrofisico di Inaf Bologna, non direttamente coinvolto nello studio ma esperto conoscitore dell’argomento. «Sarà ora interessante verificare se tali oggetti sono presenti e abbondanti anche nell’universo vicino per capire con un maggior dettaglio quali sono i meccanismi che portano alla formazione dei buchi neri supermassicci, uno dei principali misteri dell’astrofisica extragalattica».

Dopo più di mezzo secolo l’agenzia spaziale statunitense NASA sembra esser pronta a rimettere i propri astronauti sulla rotta della Luna. Lo farà in più passaggi, perché la sicurezza dell’equipaggio resta prioritario. Si parte con Artemis 2, che porterà quattro astronauti a compiere un...
L’hanno beccata grazie all’emissione dell’idrogeno neutro, Cloud-9, nube di gas situata dalle parti della galassia a spirale M94, che ci racconta una storia antica, vecchia quanto l’universo stesso. La videro per la prima volta nel 2023 alcuni astronomi cinesi, questa palla di gas grossa quanto un milione di soli, tenuta insieme da una massa di materia oscura cinquemila volte più massiccia. Una nube piccola e compatta, diversa da quelle che si notano nei dintorni della Via Lattea, e che in questi giorni sta facendo parlare di sé. Si è scoperto infatti che mai nessuna stella si accese là dentro, cosa che rende a buon diritto Cloud-9 la prima galassia mancata mai scoperta.
La notizia è uscita la scorsa settimana in una lettera a The Astrophysical Journal Letters e l’ha firmata, assieme ad altri ricercatori, Gagandeep Anand dello Space Telescope Science Institute di Baltimora, nel Maryland (Usa). Cloud-9 è quello che in gergo viene chiamato un Relhic (“Reionization-Limited H I Cloud”, dove la dicitura “H I” sta per l’idrogeno neutro), un relitto giunto a noi intonso dall’infanzia dell’universo, alone di gas e materia oscura privo di stelle, previsto dai modelli ma che mai si era riusciti a scovare. Fino a ora.
La nube di idrogeno neutro Cloud-9 (in magenta) osservata dal Very Large Array. Il cerchio delimita la regione che corrisponde al picco dell’emissione radio e su cui si è concentrata la ricerca delle stelle, effettuata col telescopio Hubble. Nessuna stella è stata rivelata, il che implica che Cloud-9 sia la prima galassia mancata mai vista. Crediti: Nasa, Esa. G. Anand, A. Benitez-Llambay; Elaborazione dell’immagine: J. DePasquale (Stsci)
«Questa è la storia di una galassia fallita», dice Alejandro Benitez-Llambay, dell’Università di Milano-Bicocca, co-scopritore del Relhic. «Nella scienza, di solito impariamo di più dai fallimenti che dai successi. In questo caso, non vedere stelle è ciò che dimostra la correttezza della teoria. Ci dice che abbiamo trovato nell’universo locale un “mattone” primordiale di una galassia che non si è ancora formata».
Come si diceva, Cloud-9 era stata avvistata per la prima volta nel 2023 dal radiotelescopio cinese Fast (“Five-hundred-meter Aperture Spherical Telescope“) ed è stata successivamente riosservata con il Green Bank Telescope e il Very Large Array, entrambi negli Stati Uniti. Larga 4900 anni luce, la “nuvola numero nove” non deve il suo nome a una felice espressione idiomatica (“to be on cloud nine” è l’equivalente inglese del nostro “essere al settimo cielo”), ma al fatto di essere stata, ben più prosaicamente, la nona nube identificata nei pressi di M94, a quattordici milioni di anni luce dal nostro pianeta.
Puntando su di essa il telescopio spaziale Hubble, gli astronomi si sono accorti che di stelle, dentro la nube, proprio non c’è traccia. Appurando dunque che Cloud-9 è una galassia mancata, dotata di una massa di materia oscura insufficiente affinché il gas potesse collassare e formare stelle. Erano anni che si cercava un oggetto fatto così, ma tutte le ricerche condotte sinora erano state infruttuose.
«Prima di usare Hubble, si sarebbe potuto sostenere che questa fosse una debole galassia nana che non potevamo vedere con i telescopi da terra. Semplicemente non erano abbastanza sensibili da riuscire a vedere le stelle», sostiene Anand. «Ma con l’Advanced Camera for Surveys di Hubble, siamo in grado di poter dire che lì non c’è nulla».

I Relhic sono oggetti previsti dal modello cosmologico attuale. Averne trovato uno fornisce dunque un’importante conferma alle sue predizioni. Essendo oggetti che giungono a noi direttamente dagli albori della storia cosmica, inintaccati dalla formazione stellare, essi costituiscono dei luoghi privilegiati per studiare i mattoni da cui si formano le galassie.
«Questa nube è una finestra sull’universo oscuro», commenta Andrew Fox, coautore dello studio. «Sappiamo dalla teoria che la maggior parte della massa dell’universo dovrebbe essere costituita da materia oscura, ma è difficile rilevarla perché non emette luce. Cloud-9 ci offre un raro sguardo su una nube dominata dalla materia oscura».
Ce ne potrebbero essere altre di galassie mancate dalle nostre parti. Il difficile è beccarle. Se troppo piccoli, gli aloni di materia oscura non sono in grado di trattenere il gas che ha consentito di rilevare Cloud-9, rimanendo dunque invisibili. Inoltre, oggetti come Cloud-9 vengono spesso “messi in ombra” dalle galassie brillanti che si trovano nei paraggi. Soprattutto, possono avere vita dura, in quanto l’idrogeno può venire loro strappato via mentre si muovono nel mezzo intergalattico.
In futuro è possibile che Cloud-9 diventi infine una galassia, a patto che acquisisca una massa sufficiente. Se questo non dovesse accadere, è probabile che continui a rimanere un Relhic, relitto alla deriva nell’eterna, accelerata, diaspora delle galassie.

Sono fra le particelle più evasive che esistano. Uno, il neutrino, è praticamente inafferrabile, capace di attraversare l’intero Sole quasi alla velocità della luce. E per l’altra, la materia oscura, il praticamente lo possiamo anche togliere, visto che almeno fino a oggi non siamo mai riusciti a intercettarla. In termini fisici si dice che non interagiscono, o interagiscono pochissimo – solo attraverso l’interazione debole, nel caso dei neutrini. Ebbene, alla faccia di questa loro capacità d’eludere senza rivali, e in contraddizione con quanto previsto dal modello cosmologico Lambda-Cdm, un nuovo studio guidato da Lei Zu del Centro polacco per la ricerca nucleare (Ncbj) di Varsavia e dall’Università di Sheffield suggerisce che queste due Houdini della fisica particellare possano invece interagire fra loro.

«I nostri risultati affrontano un enigma di lunga data nella cosmologia. Le misurazioni dell’universo primordiale», ricorda una delle autrici dello studio pubblicato il 2 gennaio su Nature Astronomy, l’astrofisica romana Eleonora Di Valentino, oggi all’Università di Sheffield, «prevedono che le strutture cosmiche debbano essersi sviluppate più rapidamente nel tempo rispetto a quanto osserviamo oggi. Tuttavia, le osservazioni dell’universo moderno indicano che la materia è leggermente meno concentrata del previsto, evidenziando una lieve discrepanza tra le misurazioni del periodo iniziale e quelle del periodo successivo».
I dati relativi all’universo primordiale utilizzati nello studio sono principalmente quelli raccolti da terra con Act, l’Atacama Cosmology Telescope, e dallo spazio con il satellite Planck dell’Agenzia apaziale europea – entrambi progettati proprio per studiare la Cmb (radiazione cosmica di fondo a microonde), vale a dire il debole bagliore residuo del Big Bang. Quanto all’universo più moderno, le osservazioni sono invece quelle della Dark Energy Survey – ottenute con lo strumento Decam montato sul telescopio Victor M. Blanco, in Cile – e della Sloan Digital Sky Survey.
È mettendo a confronto questi due insiemi di dati, provenienti da epoche diverse, che è emersa la lieve discrepanza alla quale fa riferimento Di Valentino – prima autrice, vale qui la pena ricordare, di una recente rassegna di oltre quattrocento pagine interamente dedicata alle tensioni cosmologiche. Una discrepanza nota fra gli addetti ai lavori come tensione S8, dal nome di un parametro cosmologico – il parametro S8, appunto – che quantifica l’ampiezza delle fluttuazioni della materia sulla scala degli 8 Mpc, dunque una sorta di misura della disomogeneità dell’universo. Ciò che gli autori del nuovo studio hanno trovato è che neutrini e materia oscura sembrerebbero interagire: un comportamento che potrebbe risolvere la tensione S8.
«Se questa interazione tra materia oscura e neutrini fosse confermata, si tratterebbe di una scoperta fondamentale», conclude William Giarè, coautore dello studio, oggi all’Università delle Hawaii. «Non solo getterebbe nuova luce su una persistente discrepanza tra diverse sonde cosmologiche, ma fornirebbe anche ai fisici delle particelle una direzione concreta, indicando quali proprietà cercare negli esperimenti di laboratorio per aiutare finalmente a svelare la vera natura della materia oscura».
Ai non c’è più. La scimpanzé, diventata celebre per le sue eccezionali capacità cognitive, è morta in Giappone all'età di 49 anni e causa dell'insufficienza di diversi organi legata all'età avanzata. A darne notizia è stato il personale del Centro per le origini evolutive dell'Università...
Una delle scoperte più sorprendenti dell’astronomia è che la maggior parte delle stelle simili al Sole ospita un pianeta di dimensioni comprese tra la Terra e Nettuno all’interno di un’orbita paragonabile a quella di Mercurio. Queste super-terre e sub-nettuniani sono i pianeti più comuni della nostra galassia, ma la loro formazione è rimasta avvolta nel mistero. Ora, un team internazionale di astronomi ha individuato l’anello mancante: il momento in cui pianeti neonati di un sistema planetario lontano si stanno lentamente trasformando in questi oggetti celesti così numerosi.

«La cosa più entusiasmante è che stiamo assistendo a un’anteprima di quello che diventerà un sistema planetario del tutto normale», dice John Livingston, autore principale dello studio del Centro di astrobiologia di Tokyo, in Giappone. «I quattro pianeti che abbiamo studiato probabilmente si contrarranno in super-terre e sub-nettuniani, i tipi di pianeti più comuni nella nostra galassia, di cui non abbiamo mai avuto un’immagine così chiara negli anni della loro formazione».
Lo studio si è concentrato su V1298 Tau, una stella di circa 20 milioni di anni – un battito di ciglia in termini cosmici rispetto al Sole, che ha 4,5 miliardi di anni. In orbita attorno a questa giovane stella ci sono quattro pianeti giganti, tutti di dimensioni tra Nettuno e Giove, intrappolati in una fase fugace e turbolenta della loro vita, in rapida evoluzione. Questo sistema sembra essere un antenato diretto dei sistemi planetari compatti presenti in tutta la galassia.
Per un decennio, il team ha utilizzato diversi telescopi terrestri e spaziali per misurare con precisione il momento in cui ogni pianeta passava davanti alla stella. Cronometrando questi transiti, gli astronomi hanno scoperto che le orbite dei pianeti non erano perfettamente regolari. La loro configurazione orbitale e la gravità fanno sì che si attraggono a vicenda, accelerando o rallentando leggermente. Queste piccole variazioni temporali, chiamate Transit-Timing Variations (Ttv), hanno consentito al team di misurare con precisione, per la prima volta, le masse dei pianeti.
I risultati sono stati notevoli. I pianeti, nonostante abbiano un raggio da 5 a 10 volte quello terrestre, hanno masse pari a sole 5-15 volte quelle del nostro pianeta. Hanno, cioè, una densità bassissima: sono più simili a zucchero filato di dimensioni planetarie che a mondi rocciosi.
Questo “gonfiore” contribuisce a risolvere un enigma di lunga data nella formazione planetaria. Un pianeta che si forma e si raffredda semplicemente nel corso del tempo sarebbe infatti molto più compatto. L’analisi del team rivela, invece, che questi pianeti devono aver subito una trasformazione radicale nelle prime fasi della loro evoluzione, perdendo rapidamente gran parte delle atmosfere primordiali e raffreddandosi drasticamente con la scomparsa del disco di gas attorno alla loro giovane stella. «Ma sono ancora in evoluzione. Nei prossimi miliardi di anni continueranno a perdere la loro atmosfera e a ridursi significativamente, trasformandosi nei mondi compatti che vediamo in tutta la galassia», aggiunge James Owen, coautore dell’Imperial College di Londra, che ha guidato la modellazione teorica.
«Mi viene in mente il famoso fossile di Lucy, uno dei nostri antenati, un ominide vissuto tre milioni di anni fa, che fu uno dei principali “anelli mancanti” tra scimmie antropomorfe e umani», aggiunge Erik Petigura, coautore dell’Ucla. «V1298Tau è un collegamento fondamentale tra le nebulose che formano le stelle e i pianeti che vediamo in tutto il cielo e i sistemi planetari maturi che abbiamo ormai scoperto a migliaia».
Il sistema V1298 Tau funge oggi da laboratorio per comprendere le origini dei pianeti più abbondanti della Via Lattea, offrendo agli scienziati uno sguardo senza precedenti sulla vita turbolenta e trasformativa dei mondi giovani. Lo studio di sistemi come V1298 Tau potrebbe inoltre aiutare a spiegare perché nel Sistema solare manchino le super-terre e i sub-nettuniani, così comuni altrove nella galassia.

For more than 25 years, humans have lived and worked continuously aboard the International Space Station, conducting research that is transforming life on Earth and shaping the future of exploration. From growing food and sequencing DNA to studying disease and simulating Mars missions, every experiment aboard the orbiting laboratory expands our understanding of how humans can thrive beyond Earth while advancing science and technology that benefit people around the world.
Unlocking new cancer therapies from space
NASA astronaut Christina Koch works on MicroQuin’s protein crystallization research aboard the International Space Station.
NASA
The space station gives scientists a laboratory unlike any on Earth. In microgravity, cells grow in three dimensions, proteins form higher-quality crystals, and biological systems reveal details hidden by gravity. These conditions open new ways to study disease and develop treatments.
Astronauts and researchers have used the orbiting laboratory to observe how cancer cells grow, test drug delivery methods, and examine protein structures linked to diseases such as Parkinson’s and Alzheimer’s. One example is the Angiex Cancer Therapy study, which tested a drug designed to target blood vessels that feed tumors. In microgravity, endothelial cells survive longer and behave more like they do in the human body, giving researchers a clearer view of how the therapy works and whether it is safe before human trials.
Protein crystal growth (PCG) is another major area of cancer-related study. The NanoRacks-PCG Therapeutic Discovery and On-Orbit Crystals investigations have advanced research on leukemia, breast cancer, and skin cancers. Protein crystals grown in microgravity produce larger, better-organized structures that allow scientists to determine fine structural details that guide the design of targeted treatments.
Studies in orbit have also provided insights about cardiovascular health, bone disorders, and how the immune system changes in space—knowledge that informs medicine on Earth and prepares astronauts for long missions in deep space.
By turning space into a research lab, scientists are advancing therapies that benefit people on Earth and laying the foundation for ensuring crew health on future journeys to the Moon and Mars.
Farming for the future
NASA astronauts Jessica Watkins and Bob Hines work on the eXposed Root On-Orbit Test System (XROOTS) space botany investigation, which used the station’s Veggie facility to test soilless hydroponic and aeroponic methods to grow plants. The space agricultural study could enable production of crops on a larger scale to sustain crews on future space explorations farther away from Earth.
NASA
Feeding astronauts on long-duration missions requires more than packaged meals. It demands sustainable systems that can grow fresh food in space. The Vegetable Production System, known as Veggie, is a garden on the space station designed to test how plants grow in microgravity while adding fresh produce to the crew’s diet and improving well-being in orbit.
To date, Veggie has produced three types of lettuce, Chinese cabbage, mizuna mustard, red Russian kale, and even zinnia flowers. Astronauts have eaten space-grown lettuce, mustard greens, radishes, and chili peppers using Veggie and the Advanced Plant Habitat, a larger, more controlled growth chamber that allows scientists to study crops in greater detail.
These plant experiments pave the way for future lunar and Martian greenhouses by showing how microgravity affects plant development, water and nutrient delivery, and microbial interactions. They also provide immediate benefits for Earth, advancing controlled-environment agriculture and vertical farming techniques that help make food production more efficient and resilient in challenging environments.
First year-long twin study
Mark and Scott Kelly, both former NASA astronauts, are photographed as part of NASA’s Twins Study.
NASA
Understanding how the human body changes in space is critical for planning long-duration missions. NASA’s Twins Study offered an unprecedented opportunity to investigate nature vs. nurture in orbit and on Earth. NASA astronaut Scott Kelly spent nearly a year aboard the space station while his identical twin, retired astronaut Mark Kelly, remained on Earth.
By comparing the twins before, during, and after the mission, researchers examined changes at the genomic, physiological, and behavioral levels in one integrated study. The results showed most changes in Scott’s body returned to baseline after his return, but some persisted—such as shifts in gene expression, telomere length, and immune system responses.
The study provided the most comprehensive molecular view to date of how a human body adapts to spaceflight. Its findings may guide NASA’s Human Research Program for years to come, informing countermeasures for radiation, microgravity, and isolation. The research may have implications for health on Earth as well—from understanding aging and disease to exploring treatments for stress-related disorders and traumatic brain injury.
The Twins Study demonstrated the resilience of the human body in space and continues to shape the medical playbook for the Artemis campaign to the Moon and future journeys to Mars.
Simulating deep space

The space station, which is itself an analog for deep space, complements Earth-based analog research simulating the spaceflight environment. Space station observations, findings, and challenges, inform the research questions and countermeasures scientists explore on Earth.
Such work is currently underway through CHAPEA (Crew Health and Performance Exploration Analog), a mission in which volunteers live and work inside a 1,700-square-foot, 3D-printed Mars habitat for about a year. The first CHAPEA crew completed 378 days in isolation in 2024, testing strategies for maintaining health, growing food, and sustaining morale under delayed communication.
NASA recently launched CHAPEA 2, with a four-person crew who began their 378-day simulated Mars mission at Johnson on October 19, 2025. Building on lessons from the first mission and decades of space station research, they will test new technologies and behavioral countermeasures that will help future explorers thrive during long-duration missions, preparing Artemis astronauts for the journey to the Moon and laying the foundation for the first human expeditions to Mars.
Keeping crews healthy in low Earth orbit

NASA
Staying healthy is a top priority for all NASA astronauts, but it is particularly important while living and working aboard the orbiting laboratory.
Crews often spend extended periods of time aboard the orbiting laboratory, with the average mission lasting about six months or more. During these long-duration missions, without the continuous load of Earth’s gravity, there are many changes to the human body. Proper nutrition and exercise are some of the ways these effects may be mitigated.
NASA has a team of medical physicians, psychologists, nutritionists, exercise scientists, and other specialized medical personnel who collaborate to ensure astronauts’ health and fitness on the station. These teams are led by a NASA flight surgeon, who regularly monitors each crew member’s health during a mission and individualizes diet and fitness routines to prioritize health and safety while in space.
Crew members are also part of the ongoing health and performance research being conducted to advance understanding of long-term spaceflight’s effects on the human body. That knowledge is applied to any crewed mission and will help prepare humanity to travel farther than ever before, including the Moon and Mars.
Sequencing the future
NASA astronaut Kate Rubins checks a sample for air bubbles prior to loading it in the biomolecule sequencer. When Rubins’ expedition began, zero base pairs of DNA had been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth base of DNA aboard the orbiting laboratory.
In 2016, NASA astronaut Kate Rubins made history aboard the orbital outpost as the first person to sequence DNA in space. Using a handheld device called the MinION, she analyzed DNA samples in microgravity, proving that genetic sequencing could be performed in low Earth orbit for the first time.
Her work advanced in-flight molecular diagnostics, long-duration cell culture, and molecular biology techniques such as liquid handling in microgravity.
The ability to sequence DNA aboard the orbiting laboratory allows astronauts and scientists to identify microbes in real time, monitor crew health, and study how living organisms adapt to spaceflight. The same technology now supports medical diagnostics and disease detection in remote or extreme environments on Earth.
This research continues through the Genes in Space program, where students design DNA experiments that fly aboard NASA missions. Each investigation builds on Rubins’ milestone, paving the way for future explorers to diagnose illness, monitor environmental health, and search for signs of life beyond Earth.

Si è diffusa nelle ultime ore l’ipotesi che a generare il luminoso fragore registrato nel barese la sera del 10 gennaio 2026 possa essere stato un bolide. I dati tuttavia sembrerebbero escludere tale possibilità. Le camere all-sky della rete Prisma, che da ormai dieci anni si occupa proprio di osservare i cieli italiani in cerca di meteore brillanti per ricavare l’area di caduta al suolo di eventuali frammenti meteoritici, la sera in questione non hanno avvistato alcun bolide.
«Le nostre camere di Castellana Grotte e Lecce, le più vicine alla zona», dice infatti Dario Barghini, ricercatore dell’Inaf di Torino ed esperto scienziato della rete Prisma, «non hanno registrato alcun bolide nell’orario indicato, ovvero dopo le ore 18:00. Difficilmente un evento del genere passerebbe inosservato».
Il bolide dell’11 gennaio 2026 ripreso dalla camera Prisma Itcp01 di Napoli. Crediti: Prisma/Inaf
Vi potreste invece esser persi il bolide che la notte seguente, domenica 11 gennaio, è stato registrato, alle ore 21:09 Ut circa (le 22:09 ora locale), da cinque camere in cinque diverse regioni: Amelia, Napoli, Roma, San Sepolcro e Teramo. «La triangolazione ha permesso di determinare la traiettoria dell’oggetto che», prosegue Barghini, «diretto verso nord-ovest, ha attraversato il cielo a metà strada tra le isole di Ponza e Ventotene e la costa della nostra penisola, tra Gaeta e Terracina. Dopo aver impattato l’atmosfera a 90 km di altezza con una velocità di circa 27 km/s, si è estinto dopo circa due secondi e mezzo a una quota di poco superiore ai 40 km, avendo quindi subìto una significativa decelerazione, chiaramente evidente dai dati».
L’orbita dell’oggetto era molto eccentrica: al perielio raggiungeva i paraggi del pianeta Mercurio, mentre all’afelio oltrepassava le parti più esterne della fascia degli asteroidi, spingendosi in direzione dell’orbita di Giove.
«Rimane importante», conclude Barghini, «che eventi come quello del 10 gennaio, anche se poi si risolvono in falsi allarmi, siano segnalati da chi ne è testimone perché sono comunque utili informazioni per noi ricercatori. Sul nostro sito è infatti presente un form di segnalazione bolidi».
Gas e polveri che fluiscono dalle stelle possono, nelle giuste condizioni, scontrarsi con l’ambiente circostante e creare un’onda d’urto. Un team di astronomi ha ora sfruttato il Vlt (Very Large Telescope) dell’Eso (Osservatorio europeo australe) per riprendere una splendida onda d’urto che circonda una stella morta. Ciò che hanno visto li ha lasciati perplessi: secondo tutti i meccanismi noti, la piccola stella morta Rxj 0528+2838 non dovrebbe avere attorno a sé una struttura di questo tipo. Questa scoperta, tanto enigmatica quanto sorprendente, mette alla prova la nostra comprensione di come le stelle morte interagiscono con l’ambiente circostante.

«Abbiamo trovato qualcosa di mai visto prima e, cosa ancora più importante, del tutto inaspettato», dice Simone Scaringi, professore associato presso la Durham University (Regno Unito) e coautore principale dello studio – firmato tra gli altri anche dalle astronome dell’Istituto nazionale di astrofisica Domitilla de Martino e Sara Motta – pubblicato oggi su Nature Astronomy. «Le nostre osservazioni rivelano un potente efflusso che, secondo le nostre attuali conoscenze, non dovrebbe esserci», aggiunge Krystian Ilkiewicz, ricercatore post-dottorato presso il Centro astronomico Nicolaus Copernicus di Varsavia (Polonia) e co-responsabile dello studio. Efflusso (outflow in inglese) è il termine usato dagli astronomi per descrivere il materiale espulso dagli oggetti celesti.
La stella Rxj 0528+2838 si trova a 730 anni luce di distanza da noi e, come il Sole e altre stelle, ruota intorno al centro della nostra galassia. Durante questo moto, interagisce con il gas che permea lo spazio tra le stelle, creando un tipo di onda d’urto particolare (la cosiddetta onda di prua, o bow shockin inglese), «un arco curvo di materia, simile all’onda che si forma davanti a una nave», spiega Noel Castro Segura, ricercatore presso l’Università di Warwick (Regno Unito) e collaboratore di questo studio. Queste onde di prua sono create di solito dalla materia che fuoriesce dalla stella centrale, ma nel caso di Rxj 0528+2838 nessuno dei meccanismi noti può spiegare completamente le osservazioni.
Rxj 0528+2838 è una nana bianca, il nucleo residuo di una stella di piccola massa morente, e ha una compagna simile al Sole che le orbita intorno. In questi sistemi binari, la materia della stella compagna viene trasferita alla nana bianca, attraverso la formazione di un disco. Il disco alimenta la stella morta, ma parte della materia viene espulsa nello spazio, creando potenti efflussi. Ma Rxj 0528+2838 non mostra segni della presenza di un disco, rendendo un mistero l’origine dell£efflusso e della nebulosa che ne risulta intorno alla stella.
«Scoprire che un sistema apparentemente tranquillo e privo di disco potesse generare una nebulosa così spettacolare è stata una sorpresa, uno di quei rari momenti wow», assicura Scaringi.
Il gruppo di lavoro ha individuato per la prima volta una strana nebulosità intorno a Rxj 0528+2838 nelle immagini del telescopio Isaac Newton, in Spagna. Notandone la forma insolita, l’hanno osservata più in dettaglio con lo strumento Muse installato sul Vlt dell’Eso. «Le osservazioni con lo strumento Muse dell’Eso ci hanno permesso di mappare in dettaglio l’onda d’urto e di analizzarne la composizione. Questo è stato fondamentale per confermare che la struttura provenga effettivamente dal sistema binario e non da una nebulosa o una nube interstellare non correlata», spiega Ilkiewicz.
La forma e le dimensioni dell’onda d’urto implicano che la nana bianca stia emettendo un potente efflusso da almeno mille anni. Gli scienziati non sanno esattamente come una stella morta e senza disco possa alimentare un efflusso così duraturo, ma hanno un’ipotesi.
È noto che questa nana bianca ospita un forte campo magnetico, come confermato dai dati Muse. Il campo incanala il materiale sottratto alla stella compagna direttamente sulla nana bianca, senza formare il disco intorno ad essa. «La nostra scoperta mostra che, anche senza disco, questi sistemi possono generare potenti efflussi, rivelando un meccanismo che ancora non comprendiamo. Questa scoperta sfida l’idea corrente di come la materia si muove e interagisce in questi sistemi binari estremi», aggiunge Ilkiewicz.
I risultati suggeriscono una fonte di energia nascosta, probabilmente il forte campo magnetico, ma questo “motore misterioso”, come lo definisce Scaringi, deve ancora essere studiato. I dati mostrano che la forza dell’attuale campo magnetico è sufficiente solo per alimentare un’onda d’urto della durata di poche centinaia di anni, quindi spiega solo in parte ciò che gli astronomi stanno osservando.
Per comprendere meglio la natura di questi efflussi senza disco, è necessario studiare molti altri sistemi binari. Il futuro Extremely Large Telescope (Elt) dell’Eso aiuterà gli astronomi «a mappare un numero maggiore di questi sistemi, ma anche alcuni più deboli, in dettaglio e a rivelarne di simili, contribuendo in ultima analisi a comprendere la misteriosa fonte di energia che rimane oggi inspiegata», prevede Scaringi.

NASA
NASA and its partners have supported humans continuously living and working in space since November 2000. A truly global endeavor, the International Space Station has been visited by more than 290 people from 26 countries and a variety of international and commercial spacecraft. The unique microgravity laboratory has hosted more than 4,000 experiments from over 5,000 researchers from 110 countries. The space station also is facilitating the growth of a commercial market in low Earth orbit for research, technology development, and crew and cargo transportation.
After a quarter of century of human presence in orbit, the station remains a symbol of international cooperation and a proving ground for humanity’s next giant leaps to the Moon and, eventually, Mars.
September’s full Moon, the Harvest Moon, is photographed from the space station, placed in between exterior station hardware.
NASA
The microgravity environments aboard the space station unlocks discoveries that benefit life on Earth and prepare humans for deep space missions. NASA’s Human Research Program (HRP) works to understand the changes astronauts face aboard the orbital outpost and to develop interventions to keep crews healthy before, during, and after flight.
Astronauts aboard the station exercise for roughly two hours a day to protect bone density, muscle strength, and the cardiovascular system, but the longer they are in microgravity, the harder it can be for the brain and body to readapt to gravity’s pull. After months in orbit, returning astronauts often describe Earth as heavy, loud, and strangely still. Some reacclimate within days, while other astronauts take longer to fully recover.
Through HRP-led studies, scientists track these changes and test solutions—from improved exercise regimens to medical monitoring and nutritional strategies. The results inspire new medical technologies, while teaching scientists how the human body adapts to long-duration spaceflights—knowledge that helps keep astronauts healthy on future missions.

The space station continues to be a critical platform for sharpening skills, technology, and understanding that will prepare humanity to return to the Moon with NASA’s Artemis campaign and journey on to Mars and beyond.
Since space presents an entirely new physical environment with a distinct set of challenges, the orbiting laboratory is uniquely positioned to support research and preparations not possible on Earth. That includes:
Mastering techniques for basic tasks like drinking water, sleeping, exercising, and handling various materials.
Developing solutions to microgravity-induced changes to and challenges for the human body.
Testing reliable technologies and self-sustaining ecosystems necessary for deep space travel, from life support systems to in-orbit agriculture and 3D printing of materials.
Refining techniques and procedures for data and imagery collection and analysis.
Read more about how the space station has enabled significant strides in our journey farther into the final frontier.
The first decade of the space station was the decade of construction. The second decade moved from initial studies to fully using the orbiting laboratory. Now we are in the decade of results.
With nearly 25 years of experiments conducted aboard the station, more breakthroughs are materializing than ever before. These scientific discoveries and technological advancements are benefiting humanity on the ground, contributing to the growing low Earth orbit economy, and helping to prepare for future exploration of the Moon and Mars.
Innovations include:
Advances in X-ray technologies, developed to create a space station telescope, are helping unravel the mysteries of our universe while improving medical devices on Earth.
Temperature-change data that has been employed in efforts to reduce heat absorbed by city surfaces, reduce fire risk, and help farmers efficiently water their fields.
Demonstrations of robotic technologies with the potential to relieve repetitive movement and other workplace-related stressors.
Development of a small ultrasound unit for crew health monitoring that has since been adapted to provide diagnostic care in remote areas on Earth.

NASA
NASA opens the International Space Station for scientists and researchers, inviting them to use the benefits of microgravity for commercial and public research, technology demonstrations, and more. Today, a portion of the crew’s time aboard station is devoted to private industry, including medical research that addresses complex health challenges on Earth and prepares astronauts for future deep space missions.
In collaboration with scientists at Merck, protein crystal growth research on the space station yielded early insights regarding the structure and size of particles best suited for the development of a new formulation of the company’s cancer medicine pembrolizumab for subcutaneous injection. This new route of delivery was approved by the U.S. Food and Drug Administration in September and offers a time-saving alternative to intravenous infusion for certain patients. These research efforts aboard the space station were supported by the ISS National Laboratory.
Originally, the treatment was delivered during an in-office visit via infusion therapy into the patient’s veins, a process that could take up to two hours. Initial delivery improvements reduced infusion times to less than 30 minutes every three weeks. The newly approved subcutaneous injectable form takes about one minute every three weeks, promising to improve quality of life for patients by reducing cost and significantly reducing treatment time for patients and healthcare providers.
UV imaging of a ground control sample (left) and spaceflight sample (right) from Merck’s research shows the much more uniform size and distribution of crystals grown in microgravity. These results helped researchers to refine ground-based production of uniform crystalline suspensions required for an injectable version of the company’s cancer medicine, pembrolizumab.
Merck
Since 2014, Merck has flown crystal growth experiments to the space station to better understand how crystals form, including the monoclonal antibody used in this cancer treatment. Monoclonal antibodies are lab-made proteins that help the body fight diseases. This research focused on producing crystalline suspensions that dissolve easily in liquid, making it possible to deliver the medication by injection. In microgravity, the absence of gravity’s physical forces allows scientists to grow larger, more uniform, and higher-quality crystals than those grown in ground-based labs, advancing medication development and structural modeling.
Research aboard the space station has provided valuable insights into how gravity influences crystallization, helping to improve drug formulations. The work of NASA and its partners aboard the space station improves lives on Earth, grows a commercial economy in low Earth orbit, and prepares for human exploration of the Moon and Mars.

Preparations for Next Moonwalk Simulations Underway (and Underwater)

The airliner you board in the future could look a lot different from today’s, with longer, thinner wings that provide a smoother ride while saving fuel.
Those wings would be a revolutionary design for commercial aircraft, but like any breakthrough technology, they come with their own development challenges – which experts from NASA and Boeing are now working to solve.
When creating lift, longer, thinner wings can reduce drag, making them efficient. However, they can become very flexible in flight.
Through their Integrated Adaptive Wing Technology Maturation collaboration, NASA and Boeing recently completed wind tunnel tests of a “higher aspect ratio wing model” looking for ways to get the efficiency gains without the potential issues these kinds of wings can experience.
“When you have a very flexible wing, you’re getting into greater motions,” said Jennifer Pinkerton, a NASA aerospace engineer at NASA Langley Research Center in Hampton, Virginia. “Things like gust loads and maneuver loads can cause even more of an excitation than with a smaller aspect ratio wing. Higher aspect ratio wings also tend to be more fuel efficient, so we’re trying to take advantage of that while simultaneously controlling the aeroelastic response.”
Take a minute to watch this video about the testing NASA and Boeing are doing on longer, narrower aircraft wings.
Without the right engineering, long, thin wings could potentially bend or experience a condition known as wing flutter, causing aircraft to vibrate and shake in gusting winds.
“Flutter is a very violent interaction,” Pinkerton said. “When the flow over a wing interacts with the aircraft structure and the natural frequencies of the wing are excited, wing oscillations are amplified and can grow exponentially, leading to potentially catastrophic failure. Part of the testing we do is to characterize aeroelastic instabilities like flutter for aircraft concepts so that in actual flight, those instabilities can be safely avoided.”
To help demonstrate and understand this, researchers from NASA and Boeing sought to soften the impacts of wind gusts on the aircraft, lessen the wing loads from aircraft turns and movements, and suppress wing flutter.
Reducing or controlling those factors can have a significant impact on an aircraft’s performance, fuel efficiency, and passenger comfort.
Testing for this in a controlled environment is impossible with a full-sized commercial airliner, as no wind tunnel could accommodate one.
However, NASA Langley’s Transonic Dynamics Tunnel, which has been contributing to the design of U.S. commercial transports, military aircraft, launch vehicles, and spacecraft for over 60 years, features a test section 16 feet high by 16 feet wide, big enough for large-scale models.
To shrink a full-size plane down to scale, NASA and Boeing worked with NextGen Aeronautics, which designed and fabricated a complex model resembling an aircraft divided down the middle, with one 13-foot wing.
Mounted to the wall of the wind tunnel, the model was outfitted with 10 control surfaces – moveable panels – along the wing’s rear edge. Researchers adjusted those control surfaces to control airflow and reduce the forces that were causing the wing to vibrate.
Instruments and sensors mounted inside the model measured the forces acting on the model, as well as the vehicle’s responses.

The model wing represented a leap in sophistication from a smaller one developed during a previous NASA-Boeing collaboration called the Subsonic Ultra Green Aircraft Research (SUGAR).
“The SUGAR model had two active control surfaces,” said Patrick S. Heaney, principal investigator at NASA for the Integrated Adaptive Wing Technology Maturation collaboration. “And now on this particular model we have ten. We’re increasing the complexity as well as expanding what our control objectives are.”
A first set of tests, conducted in 2024, gave experts baseline readings that they compared to NASA computational simulations, allowing them to refine their models. A second set of tests in 2025 used the additional control surfaces in new configurations.
The most visible benefits of these new capabilities appeared during testing to alleviate the forces from gusting winds, when researchers saw the wing’s shaking greatly reduced.
With testing completed, NASA and Boeing experts are analyzing data and preparing to share their results with the aviation community. Airlines and original equipment manufacturers can learn and benefit from the lessons learned, deciding which to apply to the next generation of aircraft.
“Initial data analyses have shown that controllers developed by NASA and Boeing and used during the test demonstrated large performance improvements,” Heaney said. “We’re excited to continue analyzing the data and sharing results in the months to come.”
NASA’s Advanced Air Transport Technology project works to advance aircraft design and technology under the agency’s Advanced Air Vehicles program, which studies, evaluates, and develops technologies and capabilities for new aircraft systems. The project and program fall within NASA’s Aeronautics Research Mission Directorate.
What can we do to help aircraft wings perform better in flight, creating a smoother, more fuel efficient, and safer experience for travelers? This is a quest...
Editor’s Note: This article was updated on Friday, Dec. 19, 2025, to clarify the research done by ATM-X and ACERO.
NASA’s Ames Research Center in California’s Silicon Valley continued to make strides in research, technology, engineering, science, and innovation this past year. Join us as we take a look back at some of the highlights from 2025.
From Supercomputers to Wind Tunnels: NASA’s Road to Artemis II
This video shows two simulations of the SLS (Space Launch System) rocket using NASA’s Launch Ascent and Vehicle Aerodynamics solver. For the Artemis II test flight, a pair of six-foot-long strakes will be added to the core stage of SLS that will smooth vibrations induced by airflow during ascent. The top simulation is without strakes while the bottom shows the airflow with strakes. The green and yellow colors on the rocket’s surface show how the airflow scrapes against the rocket’s skin. The white and gray areas show changes in air density between the boosters and core stage, with the brightest regions marking shock waves. The strakes reduce vibrations and improves the safety of the integrated vehicle.
NASA/NAS/Gerrit-Daniel Stich, Michael Barad, Timothy Sandstrom, Derek Dalle
By combining the technologies of the NASA Advanced Supercomputing facility and Unitary Plan Wind Tunnel at NASA Ames, researchers were able to simulate and model an adjustment to the Space Launch System (SLS) rocket that could improve airflow and stability to the vehicle during the launch of Artemis II. The collaborative effort between researchers is the next step on NASA’s journey to send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.
New Discoveries in Early Solar System Samples
A microscopic particle of asteroid Bennu, brought to Earth by NASA’s OSIRIS-REx mission, is manipulated under a transmission electron microscope. In order to move the fragment for further analysis, researchers first reinforced it with thin strips of platinum (the “L” shape on the particle’s surface) then welded a tungsten microneedle to it. The asteroid fragment measures 30 micrometers (about one-one thousandth of an inch) across.
NASA
Researchers at NASA Ames discovered a never-before-seen “gum-like” material in pristine asteroid samples delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft. The surprising substance was likely formed in the early days of the solar system, as Bennu’s young parent asteroid warmed. Such complex molecules could have provided some of the chemical precursors that helped trigger life on Earth, and finding them in the pristine samples from Bennu is important for scientists studying how life began and whether it exists beyond our planet.

Curiosity Mars Rover Uncovers Subsurface Clues to the Planet’s Evolution
NASA’s Curiosity Mars rover sees its tracks receding into the distance at a site nicknamed “Ubajara” on April 30, 2023. This site is where Curiosity made the discovery of siderite, a mineral that may help explain the fate of the planet’s thicker ancient atmosphere.
NASA/JPL-Caltech/MSSS
NASA’s Curiosity Mars rover helped shed new light on what happened to the planet’s ancient atmosphere. Researchers have long believed that Mars once had a thick, carbon dioxide-rich atmosphere and liquid water on the planet’s surface. That carbon dioxide and water should have reacted with Martian rocks to create carbonate minerals, but previous investigations haven’t found expected amounts of carbonate on the planet’s surface. Curiosity used onboard instruments to study powdered Martian rock samples from the subsurface of the planet, finding the presence of siderite, an iron carbonate mineral, within the sulfate-rich rocky layers of Mount Sharp in Mars’ Gale Crater.
Managing Satellite Traffic in Orbit
The Starling swarm’s extended mission tested advanced autonomous maneuvering capabilities.

Managed at NASA Ames, the Starling mission, in collaboration with SpaceX’s Starlink constellation, successfully demonstrated autonomous coordination between spacecraft to improve space traffic management in low Earth orbit. The extended mission, called Starling 1.5, tested how satellite swarms can share maneuver responsibilities and respond more quickly to avoid collisions without relying on time-consuming ground-based communication. This approach aims to streamline space traffic coordination as orbital congestion increases, enabling faster, safer, and more efficient satellite operations.
Proven True: A Companion Star to Betelgeuse

Data: NASA/JPL/NOIRlab. Visualization: NOIRLAB.
Researchers validated a century-old hypothesis that there’s an orbiting companion star to Betelgeuse, the 10th brightest star in our night sky. Steve Howell, a senior research scientist at Ames, used both the ground-based Gemini North telescope in Hawai’i and a special, high-resolution camera built by NASA to directly observe the close companion to Betelgeuse. This discovery may explain why other similar red supergiant stars undergo periodic changes in their brightness on the scale of many years.

NASA
New studies aboard the International Space Station are advancing the detection of antibiotic-resistant bacteria, thus improving the health safety not only of astronauts but patients back on Earth. Future astronauts visiting the Moon or Mars will need to rely on a pre-determined supply of antibiotics in case of illness, and ensuring those antibiotics remain effective is an important safety measure for future missions. Infections caused by antibiotic-resistant bacteria can be difficult or impossible to treat, making antibiotic resistance a leading cause of death worldwide and a global health concern.
Happy Third Anniversary to BioSentinel Deep Space Mission!
NASA’s BioSentinel – a shoebox-sized CubeSat – is travelling far from Earth. But that also means it’s closer than ever to being the first long-duration biology experiment in deep space.

With a second Trump Administration at the helm in 2025, NASA marked significant progress toward the Artemis II test flight early next year, which is the first crewed mission around the Moon in more than 50 years, as well as built upon its momentum toward a human return to the lunar surface in preparation to send the first astronauts — Americans — to Mars.
As part of the agency’s Golden Age of innovation and exploration, NASA and its partners landed two robotic science missions on the Moon; garnered more signatories for the Artemis Accords with 59 nations now agreeing to safe, transparent, and responsible lunar exploration; as well as advanced a variety of medical and technological experiments for long-duration space missions like hand-held X-ray equipment and navigation capabilities.
NASA also led a variety of science discoveries, including launching a joint satellite mission with India to regularly monitor Earth’s land and ice-covered surfaces, as well as identifying and tracking the third interstellar object in our solar system; achieved 25 continuous years of human presence aboard the International Space Station; and, for the first time, flew a test flight of the agency’s X-59 supersonic plane that will help revolutionize air travel.
Sean Duffy, named by President Trump, is serving as the acting administrator while NASA awaits confirmation of Jared Isaacman to lead the agency. Isaacman’s nomination hearing took place in early December, and his nomination was passed out of committee with bipartisan support. The full Senate will consider Isaacman’s nomination soon. President Trump also nominated Matt Anderson to serve as deputy administrator, and Greg Autry to serve as chief financial officer, both of whom are awaiting confirmation hearings. NASA named Amit Kshatriya to associate administrator, the agency’s highest-ranking civil servant position.
Key accomplishments by NASA in 2025 include:
Astronauts exploring Moon, Mars is on horizon
Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build upon our foundation for the first crewed mission to Mars. The Artemis II test flight is the first flight with crew under NASA’s Artemis campaign and is slated to launch in early 2026. The mission will help confirm systems and hardware for future lunar missions, including Artemis III’s astronaut lunar landing.
NASA also introduced 10 new astronaut candidates in September, selected from more than 8,000 applicants. The class is undertaking nearly two years of training for future missions to low Earth orbit, the Moon, and Mars.
Progress to send the first crews around the Moon and on the lunar surface under Artemis includes:
NASA completed stacking of its Space Launch System rocket and Orion spacecraft for Artemis II. Teams integrated elements manufactured across the country at NASA’s Kennedy Space Center in Florida, including the rocket’s boosters and core stage, as well as Orion’s stage adapter and launch abort system, to name a few.
Ahead of America’s 250th birthday next year, the SLS rocket’s twin-pair of solid rocket boosters showcases the America 250 emblem.
The Artemis II crew participated in more than 30 mission simulations alongside teams on the ground, ensuring the crew and launch, flight, and recovery teams are prepared for any situation that may arise during the test flight. Soon, crew will don their survival suits and get strapped into Orion during a countdown demonstration test, serving as a dress rehearsal for launch day.
The agency worked with the Department of War to conduct a week-long underway recovery test in preparation to safely collect the Artemis II astronauts after they splashdown following their mission.
To support later missions, teams conducted a booster firing test for future rocket generations, verified new RS-25 engines, test-fired a new hybrid rocket motor to help engineering teams better understand the physics of rocket exhaust and lunar landers, as well using various mockups to test landing capabilities in various lighting conditions. Teams also conducted human-in-the-loop testing in Japan with JAXA (Japan Aerospace Exploration Agency) with a rover mockup from their agency.
NASA also continued work with Axiom Space, to develop and test the company’s spacesuit, including completing a test run at the Neutral Buoyancy Laboratory at NASA Johnson ahead of using the suit for Artemis training. The spacesuit will be worn by Artemis astronauts during the Artemis III mission to the lunar South Pole.
On the Moon, future crew will use a lunar terrain vehicle, or LTV, to travel away from their landing zone. NASA previously awarded three companies feasibility studies for developing LTV, followed by a request for proposals earlier this year. The agency is expected to make an award soon to develop, deliver, and demonstrate LTV on the lunar surface later this decade. The agency also selected two science instruments that will be included on the LTV to study the Moon’s surface composition and scout for potential resources.
For operations around the Moon, NASA and its partners continued to develop Gateway to support missions between lunar orbit and the Moon’s surface. Construction and production of the first two elements, a power and propulsion system and habitation element, each progressed, as did development and testing of potential science and technology demonstrations operated from Gateway. International partners also continued work that may contribute technology to support those elements, as well as additional habitation capabilities and an airlock.
This past year, NASA’s Lunar Surface Innovation Consortium team collaborated with over 3,900 members from academia, industry, and government on key lunar surface capabilities. Members from across the U.S. and 71 countries participated in two biannual meetings, three lunar surface workshops, and monthly topic meetings, resulting in 10 studies, four reports, and nine conference presentations.
Building on previous missions and planning for the future, NASA will conduct more science and technology demonstrations on and around the Moon than ever before. Work toward effort included:
Selected a suite of science studies for the Artemis II mission, including studies that focus on astronauts’ health.
Launched two CLPS (Commercial Lunar Payload Services) flights with NASA as a key customer, including Firefly’s Blue Ghost Mission One, which landed on the Moon March 2, and Intuitive Machines’ Nova C lunar lander, which touched down on March 6.
Experiments and tech demos aboard these flights included an electrodynamic dust shield, lunar navigation system, high-performance computing, collection of more than 9,000 first-of-a-kind images of the lunar lander’s engine plumes, and more.
For future CLPS flights, NASA awarded Blue Origin a task order with an option to deliver the agency’s VIPER (Volatiles Investigating Polar Exploration Rover) to the lunar South Pole in late 2027, as well as awarded Firefly another flight, slated for 2030.
Teams studied regolith (lunar dirt and rocks) in a simulated lunar gravity environment and tested how solid materials catch fire in space.
The agency’s 55-pound CubeSat in lunar orbit, CAPSTONE, exceeded 1,000 days in space, serving as a testbed for autonomous navigation and in-space communications.

Technological and scientific steps toward humanity’s next giant leap on the Red Planet include:
Launched a pair of spacecraft, known as ESCAPADE, on a mission to Mars, arriving in September 2027, to study how its magnetic environment is impacted by the Sun. This data will better inform our understanding of space weather, which is important to help minimize the effects of radiation for future missions with crew.
NASA announced Steve Sinacore, from the agency’s Glenn Research Center in Cleveland, to lead the nation’s fission surface power efforts.
Selected participants for a second yearlong ground-based simulation of a human mission to Mars, which began in October, as well as tested a new deep space inflatable habitat concept.
Completed the agency’s Deep Space Optical Communications experiment, which exceeded all of its technical goals after two years. This type of laser communications has the potential to support high-bandwidth connections for long duration crewed missions in deep space.
NASA completed its fourth Entry Descent and Landing technology test in three months, accelerating innovation to achieve precision landings on Mars’ thin atmosphere and rugged terrain.
Through the Artemis Accords, seven new nations have joined the United States, led by NASA and the U.S. Department of State, in a voluntary commitment to the safe, transparent, and responsible exploration of the Moon, Mars, and beyond. With nearly 60 signatories, more countries are expected to sign in the coming months and years.
A NASA delegation participated in the 76th International Astronautical Congress in Sydney, Australia. During the congress, NASA co-chaired the Artemis Accords Principals’ Meeting, bringing together dozens of nations furthering discussions on their implementation.
Finally, NASA engaged the public to join its missions to the Moon and Mars through a variety of activities. The agency sought names from people around the world to fly their name on a SD card aboard Orion during the Artemis II mission. NASA also sponsored a global challenge to design the spacecraft’s zero gravity indicator, announcing 25 finalists this year for the mascot design. Artemis II crew members are expected to announce a winner soon.
NASA’s gold standard science benefits humanity
In addition to conducting science at the Moon and Mars to further human exploration in the solar system, the agency continues its quest in the search for life, and its scientific work defends the planet from asteroids, advances wildfire monitoring from its satellites, studies the Sun, and more.
Garnering significant interest this year, NASA has coordinated a solar system-wide observation campaign to follow comet 3I/ATLAS, the third known interstellar object to pass through our solar system. To date, 12 NASA spacecraft and space-based telescopes have captured and processed imagery of the comet since its discovery in the summer.
Astrobiology
A Perseverance sample found on Mars potentially contain biosignatures, a substance or structure that might have a biological origin but requires additional data and studying before any conclusions can be reached about the absence or presence of life.
Samples from asteroid Bennu revealed sugars, amino acids, and other life-building molecules.
Planetary Defense
In defense of Earth and protecting humanity, NASA has continued to monitor a near-Earth object that triggered potential impact notifications.
Scientists have worked to calculate more precise impact models, noting the asteroid, which poses no significant threat to Earth, has only a 0.0004% chance of hitting our planet. An international satellite determined NASA’s DART (Double Asteroid Redirect Test) released 35.5 million pounds of dust and rock from the mission’s impact in 2022.

25 years of continuous presence in low Earth orbit
In 2025, the International Space Station celebrated 25 years of continuous human presence, a milestone achievement underscoring its role as a beacon of global cooperation in space. The orbital laboratory supported thousands of hours of groundbreaking research in microgravity in 2025, advancing commercial space development and preparing for future human exploration of the Moon and Mars.
For the first time, all eight docking ports were occupied by visiting spacecraft to close out the year, demonstrating the strength of NASA’s commercial and international partnerships. Twenty-five people from six countries lived and worked aboard the station this year. In all, 12 spacecraft visited the space station in 2025, including seven cargo missions delivering more than 50,000 pounds of science, tools, and critical supplies to the orbital complex.
Research aboard the International Space Station continues to benefit life on Earth and support deep space exploration.
Several studies with Crew-10 and Crew 11 aimed at understanding how the human body adapts to spaceflight, including a new study to assess astronauts’ performance, decision making, and piloting capabilities during simulated lunar landings.
In September, the U.S. Food and Drug Administration approved an early-stage cancer treatment, supported by research aboard the space station, that could reduce costs and shorten treatment times for patients.
Scientists also published findings in peer-reviewed journals on topics such as astronaut piloting performance after long missions, the use of biologically derived materials to shield against space radiation, robotic telesurgery in space, and how spaceflight affects stem cells, all advancing our understanding of human physiology in space and on Earth.
Researchers 3D-printed medical implants with potential to support nerve repair; advanced work toward large-scale, in-space semiconductor manufacturing; and researched the production of medical components with increased stability and biocompatibility that could improve medication delivery.
Additional notable space operations accomplishments included:

Pioneering aviation research
This year saw a major triumph for NASA’s aviation researchers, as its X-59 one-of-a-kind quiet supersonic aircraft made its historic first flight Oct 28. NASA test pilot Nils Larson flew the X-59 for 67 minutes up to an altitude of about 12,000 feet and an approximate top speed of 230 mph, precisely as planned. The flight capped off a year of engine testing including afterburner testing, taxi testing, and simulated flights from the ground — all to make sure first flight went safely and smoothly. The X-59 team will now focus on preparing for a series of flight tests where the aircraft will operate at higher altitudes and supersonic speeds. This flight test phase will ensure the X-59 meets performance and safety expectations. NASA’s Quesst mission also began testing the technologies that they will use to measure the X-59’s unique shock waves and study its acoustics during future mission phases.
Researchers also made other major strides to further aviation technologies that will benefit the public and first responders, including live flight testing of a new portable airspace management system with the potential to greatly improve air traffic awareness during wildland fire operations.

The Calabash Nebula, pictured here — which has the technical name OH 231.8+04.2 — is a spectacular example of the death of a low-mass star like the Sun. This image taken by the NASA/ESA Hubble Space Telescope shows the star going through a rapid transformation from a red giant to a planetary nebula, during which it blows its outer layers of gas and dust out into the surrounding space. The recently ejected material is spat out in opposite directions with immense speed — the gas shown in yellow is moving close to a million kilometres an hour. Astronomers rarely capture a star in this phase of its evolution because it occurs within the blink of an eye — in astronomical terms. Over the next thousand years the nebula is expected to evolve into a fully fledged planetary nebula. The nebula is also known as the Rotten Egg Nebula because it contains a lot of sulphur, an element that, when combined with other elements, smells like a rotten egg — but luckily, it resides over 5000 light-years away in the constellation of Puppis (The Poop deck).

Picture this: You’re just about done with a transoceanic flight, and the tracker in your seat-back screen shows you approaching your destination airport. And then … you notice your plane is moving away. Pretty far away. You approach again and again, only to realize you’re on a long, circling loop that can last an hour or more before you land.
If this sounds familiar, there’s a good chance the delay was caused by issues with trajectory prediction. Your plane changed its course, perhaps altering its altitude or path to avoid weather or turbulence, and as a result its predicted arrival time was thrown off.
“Often, if there’s a change in your trajectory – you’re arriving slightly early, you’re arriving slightly late – you can get stuck in this really long, rotational holding pattern,” said Shivanjli Sharma, NASA’s Air Traffic Management–eXploration (ATM-X) project manager at the agency’s Ames Research Center in California’s Silicon Valley.
This inconvenience to travelers is also an economic and efficiency challenge for the aviation sector, which is why NASA has worked for years to study the issue, and recently teamed with Boeing to conduct real-time tests of an advanced system that shares trajectory data between an aircraft and its support systems.
Boeing began flying a United Airlines 737 for about two weeks in October, testing a data communication system designed to improve information flow between the flight deck, air traffic control, and airline operations centers. The work involved several domestic flights based in Houston, as well as a flight over the Atlantic to Edinburgh, Scotland.
This partnership has allowed NASA to further its commitment to transformational aviation research.

The testing was Boeing’s most recent with its ecoDemonstrator Explorer program, through which the company works with public and private partners to accelerate aviation innovations. This year’s ecoDemonstrator flight partners included NASA, the Federal Aviation Administration, United Airlines, several aerospace companies, as well as academic and government researchers.
NASA’s work in the testing involved the development of an oceanic trajectory prediction service – a system for sharing and updating trajectory information, even over a long, transoceanic flight that involves crossing over from U.S. air traffic systems into those of another country. The collaboration allowed NASA to get a more accurate look at what’s required to reduce gaps in data sharing.
“At what rate do you need these updates in an oceanic environment?” Sharma said. “What information do you need from the aircraft? Having the most accurate trajectory information will allow aircraft to move more efficiently around the globe.”
Boeing and the ecoDemonstrator collaborators plan to use the flight data to move the data communication system toward operational service. The work has allowed NASA to continue its work to improve trajectory prediction, and through its connection with partners, put its research into practical use as quickly as possible.
“This partnership has allowed NASA to further its commitment to transformational aviation research,” Sharma said. “Bringing our expertise in trajectory prediction together with the contributions of so many innovative partners contributes to global aviation efficiency that will yield real benefits for travelers and industry.”
NASA ATM-X’s part in the collaboration falls under the agency’s Airspace Operations and Safety Program, which works to enable safe, efficient aviation transportation operations that benefit the flying public and industry. The work is supported through NASA’s Aeronautics Research Mission Directorate.

NASA is helping shape the future of urban air travel with a new simulation that will manage how electric air taxis and drones can successfully operate within busy areas.
The demonstration, held at NASA’s Ames Research Center in California’s Silicon Valley earlier this year, focused on a system called the Strategic Deconfliction Simulation, which helps coordinate flight plans before takeoff, reducing the risk of conflicts in busy urban environments
At the event, researchers demonstrated NASA’s Situational Viewer and Demand-Capacity Balancing Monitor, which visualizes air traffic and adjusts flight plans in real time. The simulation demonstrated traffic scenarios involving drone operations throughout the Dallas-Fort Worth area, testing how preplanned flights could improve congestion and manage the demand and capacity of the airspace – ensuring that all aircraft can operate smoothly even in crowded conditions.
Working with industry partners is critical to NASA’s efforts to develop and refine technologies needed for future air mobility. During the simulation, the company, ANRA Technologies, demonstrated its fleet and vertiport management systems, which are designed to support the coordination of multiple aircraft and ground operations.
“Simulating these complex environments supports broader efforts to ensure safe integration of drones and other advanced vehicles into the US airspace,” said Hanbong Lee, engineer at NASA Ames. “By showcasing these capabilities, we’re delivering critical data and lessons learned to support efforts at NASA and industry.”
This demonstration is another step toward the NASA team’s plan to hold a technical capability level simulation in 2026. This upcoming simulation would help shape the development of services aimed at managing aircraft flying in urban areas.
The simulation was created through a NASA team from its Air Mobility Pathfinders project, part of the agency’s continuing work to find solutions for safely integrating innovative new aircraft such as air taxis into U.S. cities and the national airspace. By developing advanced evaluations and simulations, the project supports safe, scalable, and publicly trusted air travel in urban areas, paving the way for a future where air taxis and drones are a safe and reliable part of everyday life.

Called AVIRIS-5, it’s the latest in a long line of sensors pioneered by NASA JPL to survey Earth, the Moon, and other worlds.
Cradled in the nose of a high-altitude research airplane, a new NASA sensor has taken to the skies to help geoscientists map rocks hosting lithium and other critical minerals on Earth’s surface some 60,000 feet below. In collaboration with the U.S. Geological Survey (USGS), the flights are part of the largest airborne campaign of its kind in the country’s history.
But that’s just one of many tasks that are on the horizon for AVIRIS-5, short for Airborne Visible/Infrared Imaging Spectrometer-5, which has a lot in common with sensors used to explore other planets.
NASA’s AVIRIS flies aboard a research plane in this animation, detecting minerals on the ground such as hectorite — a lithium-bearing clay — by the unique patterns of light that they reflect. The different wavelengths, measured in nanometers, look like colorful squiggles in the box on the right. Credit: NASA’s Conceptual Image Lab
About the size of a microwave oven, AVIRIS-5 detects the spectral “fingerprints” of minerals and other compounds in reflected sunlight. Like its cousins flying in space, the sensor takes advantage of the fact that all kinds of molecules, from rare earth elements to flower pigments, have unique chemical structures that absorb and reflect different wavelengths of light.
The technology was pioneered at NASA’s Jet Propulsion Laboratory in Southern California in the late 1970s. Over the decades, imaging spectrometers have visited every major rocky body in the solar system from Mercury to Pluto. They’ve traced Martian crust in full spectral detail, revealed lakes on Titan, and tracked mineral-rich dust across the Sahara and other deserts. One is en route to Europa, an ocean moon of Jupiter, to search for the chemical ingredients needed to support life.
Image cubes illustrate the volume of data returned by JPL imaging spectrometers. The front panel shows roads and fields around Tulare, California, as seen by AVIRIS-5 during a checkout flight earlier this year. The side panels depict the spectral fingerprint captured for every point in the image.

Another imaging spectrometer, NASA’s Moon Mineralogy Mapper, was the first to discover water on the lunar surface in 2009. “That dataset continues to drive our investigations as we look for in situ resources on the Moon” as part of NASA’s Artemis campaign, said Robert Green, a senior research scientist at NASA JPL who’s contributed to multiple spectroscopy missions across the solar system.
Prisms, black silicon
While imaging spectrometers vary depending on their mission, they have certain hardware in common — including mirrors, detector arrays, and electron-beam gratings — designed to capture light shimmering off a surface and then separate it into its constituent colors, like a prism.
Light-trapping black silicon is one of the darkest materials ever fabricated. The technology is standard for JPL’s ultraprecise imaging spectrometers.
NASA/JPL-Caltech
Many of the best-in-class imaging spectrometers flying today were made possible by components invented at NASA JPL’s Microdevices Laboratory. Instrument-makers there combine breakthroughs in physics, chemistry, and material science with the classical properties of light discovered by physicist Isaac Newton in the 17th century. Newton’s prism experiments revealed that visible light is composed of a rainbow of colors.
Today, NASA JPL engineers work with advanced materials such as black silicon — one of the darkest substances ever manufactured — to push performance. Under a powerful microscope, black silicon looks like a forest of spiky needles. Etched by lasers or chemicals, the nanoscale structures prevent stray light from interfering with the sample by trapping it in their spikes.
Treasure hunting
The optical techniques used at the Microdevices Laboratory have advanced continuously since the first AVIRIS instrument took flight in 1986. Four generations of these sensors have now hit the skies, analyzing erupting volcanoes, diseased crops, ground zero debris in New York City, and wildfires in Alabama, among many other deployments. The latest model, AVIRIS-5, features spatial resolution that’s twice as fine as that of its predecessor and can resolve areas ranging from less than a foot (30 centimeters) to about 30 feet (10 meters).
So far this year, it has logged more than 200 hours of high-altitude flights over Nevada, California, and other Western states as part of a project called GEMx (Geological Earth Mapping Experiment). The flights are conducted using NASA’s ER-2 aircraft, operated out of the agency’s Armstrong Flight Research Center in Edwards, California. The effort is the airborne component of a larger USGS initiative, called Earth Mapping Resources Initiative (Earth MRI), to modernize mapping of the nation’s surface and subsurface.
The NASA and USGS team has, since 2023, gathered data over more than 366,000 square miles (950,000 square kilometers) of the American West, where dry, treeless expanses are well suited to mineral spectroscopy.
An exciting early finding is a lithium-bearing clay called hectorite, identified in the tailings of an abandoned mine in California, among other locations. Lithium is one of about 50 minerals at risk of supply chain disruption that USGS has deemed critical to national security and the economy.
Helping communities capture new value from old and abandoned prospects is one of the long-term aspirations of GEMx, said Dana Chadwick, an Earth system scientist at NASA JPL. So is identifying sources of acid mine drainage, which can occur when waste rocks weather and leach into the environment.
“The breadth of different questions you can take on with this technology is really exciting, from land management to snowpack water resources to wildfire risk,” Chadwick said. “Critical minerals are just the beginning for AVIRIS-5.”
More about GEMx
The GEMx research project is expected to last four years and is funded by the USGS Earth MRI, through investments from the Bipartisan Infrastructure Law. The initiative will capitalize on both the technology developed by NASA for spectroscopic imaging, as well as the expertise in analyzing the datasets and extracting critical mineral information from them.

NASA’s X-59 quiet supersonic research aircraft lifts off for its first flight Tuesday, Oct. 28, 2025, from U.S. Air Force Plant 42 in Palmdale, California. The aircraft’s first flight marks the start of flight testing for NASA’s Quesst mission, the result of years of design, integration, and ground testing and begins a new chapter in NASA’s aeronautics research legacy.
NASA’s X-59 quiet supersonic research aircraft took off for its historic first flight on Oct. 28, 2025, at 11:14 a.m. EDT from Lockheed Martin Skunk Works in Palmdale, California. The one-of-a-kind aircraft flew for 67 minutes before landing and taxiing to NASA’s Armstrong Flight Research Center in Edwards, California.
NASA test pilot Nils Larson flew the X-59 up to an altitude of about 12,000 feet and an approximate top speed of 230 mph, precisely as planned. The plane’s landing gear remained down during the entire flight, a common practice for experimental aircraft flying for the first time.
Now that the X-59’s first flight is in the books, the team is focused on preparing for a series of test flights where the aircraft will operate at higher altitudes and supersonic speeds. This test flight phase of NASA’s Quesst mission will ensure the X-59 meets performance and safety expectations.
Through the Quesst mission, NASA aims to usher in a new age of quiet supersonic flight, achieved through the unique design and technology of the X-59 in future supersonic transport aircraft.

The Sun blew out a coronal mass ejection along with part of a solar filament over a three-hour period on Feb. 24, 2015. While some of the strands fell back into the Sun, a substantial part raced into space in a bright cloud of particles (as observed by the NASA-ESA Solar and Heliospheric Observatory spacecraft). Because this occurred way over near the edge of the Sun, it was unlikely to have any effect on Earth.
NASA's James Webb Space Telescope captured newborn stars forming in clouds of dust and gas (colored golden and orange in this image) in a star-forming region called Pismis 24.
