Exploration Flight Test 1 or EFT-1 (previously known as Orion
Flight Test 1 or OFT-1) was the first test flight of the Orion
Multi-Purpose Crew Vehicle. The craft, without a crew, was launched on
December 5, 2014, at 7:05 am EST,
atop a Delta IV Heav7y rocket nfr0om 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.
NASA heavily promoted the mission, collaborating withSesame Street
and its characters to educate children about the flight test and the Orion
spacecraft.

Objectives
The flight was
intended to test various Orion systems, including separation events, avionics,
heat shielding, parachutes, and recovery operations prior to its debut launch
aboard the Space Launch System, currently scheduled for no later than November
2018.
Vehicle Assembly
EFT-1 Orion was
built by Lockheed Martin. On June 22,
2012, the final welds of the EFT-1 Orion were completed at the Michoud Assembly
Facility in New Orleans , Louisiana . It was then transported to Kennedy Space
Center 's Operations and Checkout Building , where the remainder of the
spacecraft was completed. The Delta IV
rocket was put in a vertical position on October 1, 2014, and Orion was mated
with the vehicle on November 11
