Live coverage: International Space Station crew lands in Kazakhstan

SpaceX’s Dragon supply ship reached the International Space Station on Wednesday, with astronaut Jeff Williams grappling the unpiloted spacecraft with the research lab’s robotic arm at 6:56 a.m. EDT (1056 GMT) after an automated rendezvous.

The United Launch Alliance Atlas 5 rocket was transferred from its assembly building to the pad at Cape Canaveral’s Complex 41 today for Friday’s launch of NASA’s Tracking and Data Relay Satellite-M that directly supports the International Space Station and various science missions.

Final preparations began this weekend at NASA’s Stennis Space Center in Mississippi to load super-cold liquid hydrogen and liquid oxygen into the massive core stage of the Space Launch System heavy-lift rocket for the first time as soon as Monday.
