A Crew Dragon spacecraft splashed down off the California coast Jan. 15, bringing back four people from the space station more than a month early.

After a health issue, four astronauts are set to leave the International Space Station early, with a pre-dawn Pacific splashdown planned for Thursday, Jan. 15.

The SpaceX Dragon spacecraft is set to splash down off Southern California following a rare medical evacuation from orbit.

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,

The four astronauts of the SpaceX Crew-11 mission undocked from the International Space Station at 5:20 p.m. EST on Wednesday.

Instead of remaining at the International Space Station (ISS) for the full duration of their mission, the four crew members are coming home a month early due to a medical issue with one of the astronauts.

SpaceX is set to launch its third mission of the year from the Space Coast on Monday afternoon while preparing for the early return later this week of Crew-11 from the International Space Station.

The departure of the Crew-11 mission has effectively left the Expedition 74 team a little thin on personnel, with only cosmonauts Sergey Kud-Sverchkov, Sergey Mikaev, and NASA's Chris Williams onboard the orbital outpost.
