Video: Orion launch replays

The United Launch Alliance Delta 4-Heavy rocket lifts off with NASA’s Orion ship on its inaugural space flight test at 7:05 a.m. EST Dec. 5 from Cape Canaveral Air Force Station’s Complex 37.

Orbital ATK has cinched $188 million in contracts to complete development of the Orion crew capsule’s needle-shaped launch abort system, resuming work stalled in the wake up a major shakeup of NASA’s human spaceflight program by the Obama administration in 2010.

Officials hailed an action-packed three-minute test flight Tuesday over Cape Canaveral that exercised the Orion spacecraft’s launch abort rocket, a key safety system on the capsule NASA is developing to carry astronauts back to the moon.
