The crew undocked from the orbiting outpost at 5:20 p.m. ET Wednesday — about a month earlier than planned —and are scheduled to splash down on Earth early Thursday.

Four people from NASA's Crew-11 mission splashed down off San Diego, successfully completing five months aboard the International Space Station. The trip was cut short due to a medical issue.

The Artemis 2 rocket, NASA's second Space Launch System booster, is currently scheduled to head out to Launch Pad 39B at the Kennedy Space Center in Florida on Saturday, Jan. 17, at 7 a.m. EST (1200 GMT). It should take several hours for the towering 322-foot rocket to reach the launch pad.

New photos show off NASA's newly constructed Roman Space Telescope, which will soon help researchers unravel the mysteries of the cosmos. Experts have also revealed when the next-gen spacecraft is set to launch and begin collecting data.

NASA’s SpaceX Crew-11 mission returned safely to Earth after 167 days in orbit, completing hundreds of hours of research aboard the International Space Station.

The members of Crew-11 — two American, one Russian and one Japanese — splashed down after one became ill, prompting an early return.

"Awards like these are a critical component of our incubator program for future missions, which combines government leadership with commercial innovation to make what is impossible today rapidly implementable in the future," said Shawn Domagal-Goldman, director of NASA's Astrophysics Division in the statement.
