Orion Flight Test 1 was the first un-crewed test flight of the Orion Multi-Purpose Crew Vehicle. It launched on December 5, 2014, at 7:05 am EST atop a Delta IV Heavy from Cape Canaveral.
The mission was a three-hour, two-orbit test of Orion. It featured a high apogee on the second orbit and a high-energy reentry at around 20,000 miles per hour. This is essentially a reenactment of the Apollo 4 mission of 1967, which validated the Apollo flight control system and heat shield.
