The multinational crew of NASA’s SpaceX Crew-12 mission is preparing for their highly anticipated return to Earth following an extensive period aboard the International Space Station. Comprising NASA astronauts Jessica Meir and Jack Hathaway, ESA (European Space Agency) astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev, the team will share insights into their mission and upcoming journey home during a live news conference from orbit on Wednesday, September 16, at 2:45 p.m. EDT.

Since their launch on February 13, 2026, the Crew-12 members have been integral to Expeditions 74 and 75, contributing to hundreds of scientific investigations. These critical experiments aim to advance human exploration beyond low Earth orbit and yield significant benefits for life on our planet. Key research areas included studying pneumonia-causing bacteria to enhance cardiovascular treatments, developing on-demand intravenous fluid generation systems for future long-duration space missions, and analyzing how physical characteristics influence blood flow in the unique environment of space.

The crew’s departure from the orbital outpost is scheduled to occur after the arrival of Crew-13 and a brief handover period, ensuring continuous human presence and operations. Mission control teams will meticulously monitor weather conditions at the designated splashdown sites off the coast of California to ensure a safe return. The International Space Station, a beacon of international collaboration for over a quarter-century, continues to be vital for pushing the boundaries of scientific knowledge, overcoming challenges inherent in human spaceflight, and laying the groundwork for ambitious future endeavors like the Artemis program’s return to the Moon and eventual missions to Mars.
