Live coverage: International crew lands in Kazakhstan

A commercial Antares rocket rolled out of a hangar on a one-mile trip to its launch pad on Virginia’s Eastern Shore on Thursday, ready for final countdown preparations ahead of liftoff Saturday morning on a cargo delivery flight to the International Space Station.

Officials from NASA, Orbital ATK, Wallops Flight Facility and the Commonwealth of Virginia preview Sunday night’s flight of the Antares rocket during the pre-launch news conference held on the eve of liftoff.

Closing out a two-day pursuit following launch from Cape Canaveral, a reused SpaceX Dragon cargo capsule arrived at the International Space Station Sunday with more than 4,800 pounds of supplies and experiments.
