Only two of the original four members of SpaceX Crew-9’s mission to the International Space Station arrived to Kennedy Space Center on Saturday, making room on their future ride home next year for the pair of NASA astronauts left behind by Boeing’s Starliner.

SpaceX's Crew-9 mission to the International Space Station on Sept. 26 will be a rescue mission of sorts, bringing up empty seats for two NASA astronauts currently in space without a ride home.

Crew-9's SpaceX Falcon 9 rocket is scheduled to lift off at 2:05 p.m. EDT Thursday from Launch Complex 40 at Cape Canaveral Space Force Station.

Elon Musk’s firm will be tasked with completing a mission Boeing’s Starliner spacecraft could not: returning two NASA astronauts back to Earth.
