It’s one thing to watch a spouse blast off on a rocketship, especially when the spacecraft is making its first flight with people on board. But it’s altogether another matter when the anxious spouse is an astronaut as well.

Three space station crew members — two short timers completing a 10-day flight and a veteran cosmonaut who has logged a world record 879 days aloft over five missions — undocked from the International Space Station and returned to Earth Friday, landing safely on the steppe of Kazakhstan to close out a problem-free flight.

A Falcon 9 rocket is being readied for a space station resupply mission at Kennedy Space Center’s launch pad 39A . The rocket is scheduled to launch at 10:01 a.m. EST (1501 GMT) on Saturday, weather permitting. Watch live coverage.
