Live coverage: Three-man crew closes out 173-day space mission

Two U.S. astronauts flanked a veteran Russian cosmonaut Thursday for a ride back to Earth from the International Space Station. The trio undocked from the station in their Soyuz spacecraft at 0757 GMT (3:57 a.m. EDT), beginning a return flight that culminated in a parachute-assisted landing on the steppe of Kazakhstan at 1145 GMT (7:45 a.m. EDT).

Rocket Lab scrubbed a planned launch from New Zealand Wednesday with 10 small Earth observation satellites for customers in the United States and Japan. Officials have not confirmed a new target launch date for the Electron rocket.

Taking a lesson from a launch mishap last June, SpaceX wrote coded commands for future Dragon cargo capsules to deploy their parachutes for an emergency landing in the event of rocket failures, starting with Friday’s resupply flight to the International Space Station.
