Four astronauts from NASA’s Crew-10 mission have completed their journey back to Earth after almost five months aboard the International Space Station.
The team—Anne McClain and Nichole Ayers from the United States, Takuya Onishi from Japan, and Kirill Peskov from Russia—undocked from the ISS on August 8, 2025, in a SpaceX Dragon capsule.
After an 18-hour trip through low Earth orbit, they splashed down safely in the Pacific Ocean off California’s coast at 15:33 UTC on August 9.
This mission served as NASA’s tenth commercial crew rotation, part of ongoing efforts to maintain continuous human presence in space.
Over their 146-day stay, the crew carried out more than 200 experiments, focusing on topics such as plant growth in microgravity and the way human cells behave without Earth’s gravity.
These studies are intended to improve conditions on Earth and help prepare for long-duration missions, including those targeting the Moon.
Crew-10 took over from Crew-9 after a unique situation earlier in the year.
Crew-9 astronauts Barry Wilmore and Sunita Williams were stranded aboard the ISS for nine months due to a propulsion fault with their Boeing Starliner capsule. A SpaceX Dragon later returned them safely to Earth.
NASA has since confirmed Wilmore’s retirement after 25 years of service.
Meanwhile, a new four-member team—Zena Cardman and Mike Fincke of the United States, Kimiya Yui from Japan, and Oleg Platonov from Russia—has begun a six-month stay on the ISS.
Their work will continue vital experiments and strengthen international partnerships as NASA advances plans for future Moon and deep-space missions.
