Crew-12 Returns After Eight-Month ISS Mission

NASA and SpaceX brought Crew-12 home with a Pacific splashdown off Los Angeles, closing a 237-day mission that mixed science, station upkeep, and international crew rotation. The return also underscored how routine human spaceflight has become for SpaceX, even as the mission marked first flights for two crew members and a major milestone for Jessica Meir.

Crew-12’s Pacific Ocean splashdown marked the end of a long, tightly choreographed mission that blended exploration, science, and station operations. The four-person crew returned aboard a SpaceX Crew Dragon capsule after 237 days aboard the International Space Station, ending a mission that began with a February launch on a Falcon 9 rocket from Cape Canaveral. NASA and SpaceX brought the spacecraft down off the coast of Los Angeles after a controlled deorbit burn, reentry through extreme heat, and parachute-assisted descent to a gentle landing.

The mission’s significance extends beyond the safe return itself. Jessica Meir commanded the flight, with Jack Hathaway piloting and Sophie Adenot of the European Space Agency and Andrey Fedyaev of Roscosmos serving as mission specialists. NASA said the crew completed dozens of experiments during the eight-month stay, including studies of stem cells, crystal growth in space, and bone loss in microgravity. The team also performed four spacewalks. Meir completed four spacewalks totaling just over 27 hours to help maintain and upgrade the aging orbital outpost, while Adenot carried out three spacewalks. For Hathaway and Adenot, it was their first trip to space, while Fedyaev flew for the second time.

The return also highlighted the increasingly established role of SpaceX in human spaceflight. Crew-12 was SpaceX’s 20th human mission, reflecting how regular ISS crew transport has become. The capsule’s descent, from orbital speed to a water landing in about half an hour, showed the precision now required for routine returns from orbit. Recovery teams moved quickly to secure Dragon and prepare the astronauts to exit the spacecraft.

The broader operational picture is one of continuity and handoff. Crew-12 was relieved by Crew-13, which arrived last week to begin its own six-month rotation. Meir, now with 440 total days in space, ranks among NASA’s top 10 for cumulative time in orbit. Her comments before departure captured the human side of the mission: she looked forward to seeing nature again, feeling the breeze, and being reunited with her daughter, even as she acknowledged she would miss weightlessness and the view of Earth.
