Just over a day after blasting off, a SpaceX crew capsule arrived at the International Space Station on Sunday, delivering the replacements for NASA’s two stuck astronauts.
The four newcomers — representing the U.S., Japan and Russia — will spend the next few days learning the station’s ins and outs from Butch Wilmore and Suni Williams. Then the two will strap into their own SpaceX capsule later this week to close out an unexpected extended mission that began last June.
