Video: Soyuz launches three-person international crew

Bidding their crewmates farewell, a Russian cosmonaut and two NASA astronauts boarded their Soyuz ferry craft, undocked from the International Space Station and fell back to Earth Tuesday, landing safely on the snowy steppe of Kazakhstan to close out a 168-day mission.

SpaceX’s second Falcon Heavy rocket lifted off Thursday with the Arabsat 6A communications satellite. The world’s most powerful operational launcher lifted off from pad 39A at NASA’s Kennedy Space Center in Florida at 6:35 p.m. EDT (2235 GMT), and its three first stage boosters landed less than 10 minutes later — two back at Cape Canaveral and one on a drone ship at sea.

China launched its second space mission in less than 24 hours Tuesday, sending a Beidou navigation satellite toward an orbital perch around 22,000 miles above Earth.
