Video: Soyuz MS-01 leaves the space station for landing

The Dragon supply ship set for liftoff from Florida next month was the last of SpaceX’s first-generation cargo capsules off the production line, meaning future logistics deliveries to the International Space Station will fly on recycled spacecraft until a new Dragon variant is ready.

Crew Dragon astronauts Douglas Hurley and Robert Behnken thanked their space station crewmates for a productive two-month visit, readied their SpaceX capsule for departure and stood by for a final “go” from flight controllers to undock Saturday night, setting up a Gulf of Mexico splashdown Sunday afternoon.

Pettit will fly to the orbiting outpost alongside Russian cosmonauts Alexey Ovchinin and Ivan Vagner on the Soyuz MS-26 mission. Liftoff from the Baikonur Cosmodrome is set for 12:23 p.m. EDT (1623 UTC).
