Exploration Flight Test-1
Exploration Flight Test-1 or EFT-1 (previously known as Orion Flight Test 1 or OFT-1) was the first test flight of the crew module portion of the Orion Multi-Purpose Crew Vehicle. Without a crew, it was launched on December 5, 2014, at 12:05 UTC (7:05 am EST), by a Delta IV Heavy rocket from Space Launch Complex 37B at Cape Canaveral Space Force Station.

The mission was a four-hour, two-orbit test of the Orion crew module featuring a high apogee on the second orbit and concluding with a high-energy reentry at around 8.9 kilometers per second (20,000 mph). This mission design corresponds to the Apollo 2/3 missions of 1966, which validated the Apollo flight control system and heat shield at re-entry conditions planned for the return from lunar missions.
NASA heavily promoted the mission, collaborating with Sesame Street and its characters to educate children about the flight test and the Orion spacecraft.
