NASA’s stuck astronauts welcome their newly arrived replacements to the space station

A SpaceX capsule has arrived at the International Space Station, delivering the replacements for NASA’s two stuck astronauts. The new crew pulled up Sunday, just 29 hours after blasting off. The four newcomers will spend the next few days learning the station’s ins and outs from Butch Wilmore and Suni Williams. Then it will be time for those two to end their nine-month stay and head home. They expected to be gone just a week when they launched on Boeing’s first astronaut flight last June. The Starliner capsule had so many problems that NASA insisted it come back empty. Wilmore and Williams will come back via SpaceX.
