After spending more than nine months aboard the International Space Station (ISS), NASA astronauts Butch Wilmore and Sunita Williams are set to return to Earth. The National Aeronautics and Space Administration (NASA) announced that both astronauts will return on Tuesday, March 18, evening (GMT).

Butch Wilmore and Sunita Williams, along with another American astronaut and a Russian cosmonaut, will be transported back to Earth aboard a SpaceX Crew Dragon spacecraft, which arrived at the ISS early Sunday.

“NASA and SpaceX met on Sunday to assess weather and splashdown conditions off Florida’s coast for the return of the agency’s Crew-9 mission from the International Space Station. Mission managers are targeting an earlier Crew-9 return opportunity based on favorable conditions forecasted for the evening of Tuesday, March 18,” NASA said in a released statement.
