Video: Change of command aboard International Space Station

Three days after a trio of space station fliers returned to Earth, a Russian cosmonaut, a German flight engineer and a NASA physician-astronaut rocketed into orbit aboard another Soyuz spacecraft Wednesday, setting off after the lab complex in the first step of a two-day rendezvous.

An automated SpaceX supply ship parachuted into the Pacific Ocean on Saturday, bringing more than 3,800 pounds of cargo — including a NASA robot requiring repair — back to Earth after a month-long mission at the International Space Station.

The four members of the SpaceX Crew-11 flight were previously set to fly on different missions before they ended up as a quartet on the Dragon Endeavour spacecraft. Liftoff of the Falcon 9 rocket from pad 39A at NASA’s Kennedy Space Center is scheduled for no earlier than Friday, Aug. 1, at 11:43 a.m. EDT (1543 UTC).
