NASA’s Exploration Flight Test 1, or EFT-1, will mark the first-ever test flight of the agency’s Orion spacecraft for deep-space exploration. The unmanned test flight, scheduled for Dec. 4, 2014, will send an unmanned Orion space capsule on a 4.5-hour spaceflight to simulate the re-entry of a mission to the moon. NASA scheduled the Orion capsule’s first test flight for Dec. 4, 2014. The uncrewed spacecraft will travel to a height of 3,600 miles (5,800 km) and orbit
Earth twice during a 4.5 hour mission.
