An anonymous reader quotes a report from Ars Technica: Preparations for the first human spaceflight to the Moon in more than 50 years took a big step forward this weekend with the rollout of the Artemis II rocket to its launch pad. The rocket reached a top speed of just 1 mph on the four-mile, 12-hour journey from the Vehicle Assembly Building to Launch Complex 39B at NASA's Kennedy Space Center in Florida. At the end of its nearly 10-day tour through cislunar space, the Orion capsule on top of the rocket will exceed 25,000 mph as it plunges into the atmosphere to bring its four-person crew back to Earth. "This is the start of a very long journey," said NASA Administrator Jared Isaacman. "We ended our last human exploration of the moon on Apollo 17." [...] "We really are ready to go," said Wiseman, the Artemis II commander, during Saturday's rollout to the launch pad. "We were in a sim [in Houston] for about 10 hours yesterday doing our final capstone entry and landing sim. We got in T-38s last night and we flew to the Cape to be here for this momentous occasion." The rollout began around sunrise Saturday, with NASA's Space Launch System rocket and Orion capsule riding a mobile launch platform and a diesel-powered crawler transporter along a throughway paved with crushed Alabama river rock. Employees, VIPs, and guests gathered along the crawlerway to watch the 11 million-pound stack inch toward the launch pad. The rollout concluded about an hour after sunset, when the crawler transporter's jacking system lowered the mobile launch platform onto pedestals at Pad 39B. The rollout keeps the Artemis II mission on track for liftoff as soon as next month, when NASA has a handful of launch opportunities on February 6, 7, 8, 10, and 11. The big milestone leading up to launch day will be a practice countdown or Wet Dress Rehearsal (WDR), currently slated for around February 2, when NASA's launch team will pump more than 750,000 gallons of super-cold liquid hydrogen and liquid oxygen into the rocket. NASA had trouble keeping the cryogenic fluids at the proper temperature, then encountered hydrogen leaks when the launch team first tried to fill the rocket for the unpiloted Artemis I mission in 2022. Engineers implemented the same fixes on Artemis II that they used to finally get over the hump with propellant loading on Artemis I. [...] If the launch does not happen in February, NASA has a slate of backup launch dates in early March.

Alle 18:42 Eastern Time di sabato 17 gennaio (le 00:42 di domenica mattina in Italia) il razzo Sls (Space Launch System) Artemis II della Nasa e la navicella spaziale Orion hanno raggiunto la piattaforma di lancio 39B dopo un viaggio di quasi 12 ore dal Vehicle Assembly Building (Vab) del Kennedy Space Center della Nasa, in Florida.

Poche ore prima, il crawler-transporter 2 della Nasa aveva iniziato il suo viaggio di poco meno di sei chilometri e mezzo con l’Sls e l’Orion integrati e impilati sulla sua sommità. Muovendosi a una velocità massima di soli 1,32 chilometri all’ora, il crawler ha trasportato il gigantesco razzo lunare e la navicella spaziale – complessivamente, oltre 98 metri d’altezza – lentamente ma inesorabilmente verso la piattaforma di lancio, facendo una pausa programmata per consentire ai team di riposizionare il braccio di accesso dell’equipaggio, un ponte che fornisce agli astronauti e all’equipaggio di chiusura l’accesso a Orion il giorno del lancio.

Nei prossimi giorni, ingegneri e tecnici prepareranno il razzo Artemis II per la prova generale, un test delle operazioni di rifornimento e delle procedure di conto alla rovescia. Entro il 2 febbraio il team caricherà il razzo con propellenti criogenici, avvierà il conto alla rovescia e si eserciterà a scaricare in sicurezza i propellenti dal razzo: tutte fasi essenziali prima della prima missione Artemis con equipaggio.

Potrebbero essere necessarie ulteriori prove generali per garantire che il veicolo sia completamente controllato e pronto per il volo. E, se necessario, dopo la prova generale la Nasa potrebbe riportare Sls e Orion al Vehicle Assembly Building per ulteriori lavori prima del lancio.

A bordo del primo volo umano di Artemis II ci saranno gli astronauti della Nasa Reid Wiseman, Victor Glover e Christina Koch e l’astronauta della Csa (Canadian Space Agency) Jeremy Hansen. In un viaggio di circa dieci giorni raggiungeranno la Luna, le orbiteranno intorno e poi faranno rientro verso la Terra. Si tratta di un passo avanti importante per le nuove missioni con equipaggio sulla superficie lunare, le prime della Nasa dopo il programma Apollo e che prevedono di portare una presenza costante sulla Luna.

 

«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).

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.

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.

• Conducted live flight testing with aircraft performing simulated wildland fire response using NASA’s new portable airspace management system known as Advanced Capabilities for Emergency Response Operations (ACERO) project. 
• Used NASA’s Transonic Dynamics Tunnel in Virginia to test the performance of rotors designed for NASA’s Dragonfly rotorcraft, which will explore Saturn’s moon, Titan. 
• Performed wind tunnel tests to see how icing could affect longer, thinner wings on future airliners and to evaluate a tiltwing design likely to see wide usage in advanced air mobility vehicles. 
• Tested NASA-designed ultralight aerogel antennas that could be embedded into aircraft skin for more aerodynamic, reliable, satellite communications. 
• Worked to advance the airborne transportation of people and goods, including a collaboration with the Department of War to advance capabilities for long-distance cargo drones; a partnership to test a tool for remotely piloted urban air transportation; flight tests with partners exploring large-scale drone cargo flights; and work with ResilienX to enhance preflight planning for safer future skies. 
• Performed research to help with the integration of air taxis and similar future aircraft, such as producing real-world data to help understand their flight dynamics; dropping a full-scale fuselage model to test its materials upon impact; collecting to evaluate strategies for urban airspace integration; investigating passenger comfort; and testing 5G-based aviation network technology to boost air taxi connectivity. Evaluated a system that would help prevent collisions between air taxis and other future aircraft in urban environments.  
• Made advances to unsteady pressure sensitive paint wind tunnel technology, allowing it to measure air pressure on miniature aircraft and rocket models 10,000 times faster with 1,000 times higher resolution. 
• Collected data on mixed reality systems that allow users to interact with physical flight simulators while wearing virtual reality headsets.  
• Developed the GlennICE tool for U.S. researchers and aircraft developers to integrate icing-related considerations into aircraft design. 
• Supported research for safer and smoother airline and airport operations, including; developing a preflight rerouting tool to actively curb commercial airline delays and save fuel; demonstrating a unique air traffic management concept for safer aircraft operate at higher altitudes; and hosting technology testing to make runway taxiing safer and more efficient.
• Adapted technology that can measure temperature and strain on high-speed air vehicles for hypersonic flights at speeds greater than Mach 5. 
• Provided funding for 14 university teams to build innovative new compact emergency response aircraft; issued new awards for university teams to participate in real-world aviation challenges, including the program’s first to a community college. NASA also named winners in the 2025 Gateways to Blue Skies competition, as well as selected new student teams for the University Leadership Initiative.
