Today marks the second anniversary of Exploration Flight Test 1 or EFT-1 (previously known as Orion Flight Test 1 or OFT-1) which was the first test flight 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 Air 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 20,000 miles per hour (32,000 km/h; 8,900 m/s). This mission design corresponds to the Apollo 4 mission of 1967, which validated the Apollo flight control system and heat shield at re-entry conditions planned for the return from lunar missions.

The four and a half hour flight took the Orion spacecraft on two orbits of #Earth. Peak altitude was approximately 5,800 kilometers (3,600 mi). The high altitude allowed the #spacecraft to reach reentry speeds of up to 20,000 mph (32,000 km/h; 8,900 m/s), which exposed the #heatshield to temperatures up to around 4,000 °F (2,200 °C).
