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

The first 34 satellites manufactured on a new commercial spacecraft assembly line just outside the gates of the Kennedy Space Center in Florida are scheduled for liftoff on a Soyuz rocket Thursday halfway around the world in Kazakhstan, kicking off a sequence of up to 20 launches from three countries to deploy nearly 650 satellites for OneWeb’s global Internet network.

The four-member crew will now fly onboard Dragon Endurance instead of SpaceX’s fifth Crew Dragon spacecraft as originally intended. Launch has moved up to Wednesday, March 12, “pending mission readiness and completion of the agency’s certification of flight readiness process.”

These photos show the stacking of Japan’s eighth H-2B rocket inside an assembly building at the Tanegashima Space Center over the past few weeks, followed by rollout of the 186-foot-tall vehicle to its launch pad Tuesday.
