The final pair of solar arrays will complete the space station’s power system augmentation, boosting available electricity for research, operations, and the station’s safe, controlled deorbit. Astronauts will install the arrays during a series of spacewalks planned for later this fall.

Dragon also is delivering several new experiments, including hardware to manufacture artificial retinas in microgravity that could help restore vision for patients on Earth and 3D heart tissue models to advance large-scale drug testing on future space missions. Dragon also will carry materials to study how a new type of glass is formed in microgravity, and brain organoids that could uncover potential treatment targets for neurodegenerative diseases like Alzheimer’s, Parkinson’s, and multiple sclerosis.

These are just a sample of the hundreds of investigations conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Research and technology investigations taking place aboard the space station benefit people on Earth and lay the groundwork for other agency deep space missions. As part of NASA’s Artemis program, the agency will send astronauts to the Moon to prepare for future human exploration of Mars, inspiring the world through discovery in a new Golden Age of innovation and exploration.

The Dragon spacecraft is scheduled to remain at the space station until mid-November when it will depart and return to Earth with time-critical research and cargo, splashing down off the coast of California.

NASA experiments focused on human and plant health and drug-resistant organisms will travel to the International Space Station aboard SpaceX’s 35th Commercial Resupply Services mission for the agency from Cape Canaveral Space Force Station in Florida, advancing research that benefits life on Earth and future exploration.

This research supports astronaut health during long-duration missions through four investigations from the agency’s Biological and Physical Sciences division, including 3D models of the human brain, a crop disease study, a faster way to assess astronaut health, and an analysis of antibiotic-resistant bacteria aboard the space station.

Tiny brain models, big questions

A new precision health investigation helps address a key question: What happens to the human brain in space?

The experiment sends small, lab-grown models of the human brain to the orbiting laboratory for five weeks. Researchers compare tissue models that traveled to space with identical ones kept on Earth to determine how a short spaceflight affects the human brain at the cellular level.

The effort could deepen our understanding of how the human brain responds to stress and help lay the groundwork for methods that counter risks to brain health that astronauts may face on future missions to the Moon and beyond.

Disease-resistant crops for space

A space crops investigation tests whether crop diseases develop faster and more severely in microgravity.

The experiment compares molecular and structural changes between Earth-grown and space station-grown plants infected with a disease-causing fungus. The findings could guide plant breeding on Earth to produce disease-resistant crops and help minimize yield losses in future space agriculture systems.

Space crops provide nutrition, increase dietary variety, and offer psychological benefits for astronauts during extended missions. They also absorb carbon dioxide, produce oxygen, and recycle water, which will become increasingly important as human missions extend farther from Earth.

Analysis helps astronauts thrive

The spacecraft also carries the first test of a compact microplate reader that arrived aboard the space station earlier this year.

The Commercially Enabled Rapid Space Science initiative experiment tests the device’s ability to detect and measure certain biomarkers such as antibodies, antigens, and proteins.

Use of the plate reader would allow scientists to analyze samples aboard the space station and obtain data quickly, rather than wait for the samples to return to Earth for analysis.

Ultimately, the research aims to support the timely detection of infections and other health issues in astronauts while expanding science capabilities in remote exploration locations where resupply will be more difficult.

Tracking antibiotic-resistant bacteria

A precision health investigation returns for its fourth and final planned stay aboard the space station to study how antibiotic-resistant bacteria survive and evolve in microgravity.

As part of the investigation, astronauts repeatedly sample surfaces throughout the space station to monitor for drug-resistant organisms.

The work could help develop ways to protect astronauts against bacterial infections during long-duration missions. On Earth, the findings could provide insight into how superbugs develop from the overuse of antibiotics.

For more than 25 years, the International Space Station has supported research by scientists from more than 110 countries, enabling more than 4,000 experiments in microgravity. Research conducted aboard the station helps advance long-duration missions to the Moon as part of the Artemis program and to Mars, while also providing multiple benefits to humanity.

Science Highlights

In addition to cargo for the crew aboard the space station, Dragon will deliver several new science experiments, including:

With LambdaVision-1, NASA is testing how to manufacture artificial eye retinas in microgravity, building them one thin layer at a time. Reduced settling in microgravity may create more uniform, stable layers, potentially improving implants’ performance. These artificial retinas could help restore vision for patients with currently incurable retinal diseases on Earth.

NASA will use the Stellar Spheroids experiment to study how microgravity affects the growth and function of 3D human heart tissue models. Researchers will assess whether microgravity improves the formation of advanced vascular networks. Results could help researchers develop more realistic heart tissue models for disease research and support larger‑scale drug testing on future space missions.

Using non-traditional elements, ELF-Unconventional Glass 2 studies how glass forms in microgravity. Researchers will observe molten behavior in space, then return solid samples to Earth for detailed analysis. These unconventional glasses could offer higher strength, improved optical capabilities, and greater durability for spacecraft, habitats, and other exploration technologies.

The MINDS experiment studies brain organoids to better understand inflammation linked to neurodegenerative diseases. The investigation uses “organoid villages,” which combine cells from multiple people to better represent patient diversity. Results could help identify new treatment targets for diseases like Alzheimer’s, Parkinson’s, and multiple sclerosis.

Arrival and Return

NASA astronaut Anil Menon and CSA (Canadian Space Agency) astronaut Joshua Kutryk will monitor the Dragon spacecraft’s arrival. It will remain docked to the orbiting laboratory for about a month before splashing down in the Pacific Ocean, returning critical science and hardware to teams on Earth. 

Cargo Highlights

Launch 

International Space Station Roll-Out Solar Arrays (IROSA) – The final pair of IROSAs that will be installed on the space station, completing the augmentation of its power system to support critical operations, including its safe and controlled deorbit.

Collapsible Continency Urinal and supporting hardware – A demonstration and test unit supporting NASA’s Artemis III mission.  

Canadarm2 joint flight support equipment – A large foam clamshell will fly empty to return the failed robotic arm joint that was replaced during a June 30 spacewalk. After its return to Earth, teams will analyze the joint on the ground.

Additional equipment launching includes a toilet dose pump, a toilet pretreat quality sensor, and a robot micro-conical tool used for space station maintenance and utilization tasks with external replacement units and payloads.

Return

When Dragon returns in mid‑November, it will bring back the failed joint on the Canadarm2 for analysis and refurbishment, a spacesuit for ground refurbishment, a fluid- and pressure-control pump assembly from the urine processor, and a filtration unit for the water processor assembly.
