NASA's stranded astronauts are set to come back as SpaceX sends a new crew to replace them.
Reading
New astronauts went to the space station. They will replace two astronauts who were stuck there. The stuck astronauts, Butch Wilmore and Suni Williams, need them to arrive before they can leave.
NASA wants the crews to overlap. This way, Wilmore and Williams can teach the new crew about the station. Then, Wilmore and Williams will return to Earth, landing off the Florida coast.
Wilmore and Williams were supposed to be gone for a week. But, problems with their spacecraft delayed their return. NASA and Boeing investigated the problems for many months.
NASA decided it was not safe for the spacecraft to return with them. So, they were moved to a different flight. Their return was delayed again because the new spacecraft needed repairs.
Wilmore and Williams supported NASA's decisions during their extended stay. They helped keep the space station running. They fixed things, did experiments, and even went on a spacewalk together.
