Video: SpaceX Dragon departs space station

Russia’s next Progress cargo freighter rolled out to its launch pad in Kazakhstan on Tuesday in a final move before blasting off Thursday at the tip of a Soyuz rocket to resupply and refuel the International Space Station.

SpaceX conducted a final Launch Readiness Review on Monday ahead of the scheduled liftoff Wednesday of NASA astronauts Doug Hurley and Bob Behnken on a test flight of the Crew Dragon spacecraft to the International Space Station. Launch remains set for 4:33:33 p.m. EDT (2033:33 GMT) Wednesday, weather permitting.

The mission will see the debut of several upgrades to the launch vehicle, including redesigned engines. Liftoff from Pad 2 at Starbase, Texas, is scheduled during a window that opens at 5:30 p.m. CDT (6:30 p.m. EDT / 2230 UTC).
