NASA Administrator speaks about Orion test flight

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.

A four-man crew led by a former NASA astronaut intends to blast off early next year aboard a SpaceX Crew Dragon capsule for a flight to the International Space Station, the first such purely commercial, non-government flight to orbit in space history, officials said Tuesday.

Watch the Atlas 5 rocket and OSIRIS-REx asteroid sample return spacecraft pre-launch news conference and the mission science briefing held on Launch-minus 2 days at the Kennedy Space Center.
