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.

A forecast of low ceilings, thick clouds and rainy weather Thursday has led NASA and Northrop Grumman officials to push back the launch of an Antares rocket and a space station-bound supply ship from Virginia’s Eastern Shore to Friday morning.

United Launch Alliance’s Atlas 5 rocket, modified for crewed launches, rolled out of the Vertical Integration Facility Wednesday for the 1,800-foot trek to pad 41 in preparation for liftoff with Boeing’s Starliner crew capsule on an unpiloted mission to the International Space Station.
