SpaceX and NASA have planned to undock the Crew-9 Dragon spacecraft from the ISS

SpaceX and NASA are set to undock the Crew-9 Dragon spacecraft from the International Space Station (ISS) on Tuesday, March 18, 2025, at 1:05 a.m. ET, with a splashdown planned off Florida’s coast approximately 17 hours later at 5:57 p.m. ET.

The spacecraft, carrying NASA astronauts Nick Hague, Suni Williams, and Butch Wilmore, along with Roscosmos cosmonaut Aleksandr Gorbunov, launched on September 28, 2024, from Kennedy Space Center’s Launch Complex 39A aboard a Falcon 9 rocket.

Williams and Wilmore, originally flown to the ISS in June 2024 via Boeing’s Starliner, joined Crew-9 for their return after Starliner’s technical issues extended their mission from 8 days to over 9 months.

After undocking, Dragon will perform departure burns, orbit-lowering maneuvers, and trunk jettison before re-entering Earth’s atmosphere, with live webcasts starting at 12:50 a.m. ET for undocking and 4:57 p.m. ET for splashdown, available on X (@SpaceX), the X TV app, and NASA+.

During their stay, the crew completed over 900 hours of research, including experiments on microalgae oxygen production, solar wind studies, and hearing tests, contributing significantly to scientific advancements in space.
