Crew-11 mission from the International Space Station. Crew Dragon Endeavour and its crew of four — comprised of two NASA astronauts, one Japanese astronaut, and one Russian cosmonaut — are scheduled to splashdown in the Pacific Ocean a few hours later at 12:40 AM PST (08:40 UTC) on Thursday,

A medical issue prompted the first-ever emergency return from the International Space Station, which was put into Earth's orbit in 1998.

After more than five months in space, four astronauts on a mission known as Crew-11 are about to cut their mission short and return to Earth.

SpaceX’s Crew-11 is returning from the International Space Station (ISS) early due to a medical concern with one of its astronauts. It’s the first recorded case in which NASA has decided to bring home a crew member ahead of time due to a health issue.

All four Crew 11 fliers looked healthy and in good spirits on a space-to-ground television broadcast of the change of command ceremony with no indication of which astronaut may have experienced the undisclosed medical issue that triggered Crew 11's early departure.
