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

SpaceX’s 28th resupply mission to the International Space Station lifted off Monday from the Kennedy Space Center, carrying new solar arrays, fresh food, and experiments to sustain research and upgrade the power system on the orbiting laboratory.

Two astronauts worked outside the International Space Station Wednesday to reposition two spare solar array ammonia coolant pump assemblies, putting a failed unit, dubbed “Leaky,” into long-term storage and attaching another, known as “Frosty,” to an appendage of the lab’s robot arm.

SpaceX has delayed liftoff of its next cargo ship bound for the International Space Station until Friday, setting up a one-shot attempt to launch the commercial supply carrier from Cape Canaveral before a potential slip to late December due to high solar angles in orbit.
