(Bloomberg) — NASA selected Elon Musk’s SpaceX to bring home the US astronauts who were forced to extend their stay at the International Space Station because of major technical issues with Boeing Co.’s capsule.

Boeing’s spacecraft will return without people on board, the US space agency said during a Saturday news conference announcing its decision.

The contingency plan means that NASA astronauts Barry “Butch” Wilmore and Sunita “Suni” Williams will hitch a ride home on SpaceX’s rival Crew Dragon capsule during a mission slated to launch in late September. That would put them back on US soil in February, when that capsule is slated to return and months later than originally planned.
