The Orion spacecraft’s first mission, called Exploration Flight Test-1 (EFT-1), launched into space on Dec. 5, 2014. Orion launched on a Delta-IV Heavy booster, flying to an altitude of 3,600 miles above the Earth. The 4.5-hour uncrewed mission demonstrated Orion’s space-worthiness, tested the spacecraft’s heat shield during reentry into the Earth’s atmosphere, and proved the capsule’s recovery systems.
At 7:05 a.m. EST on Dec. 5, 2014, the three-core first stage of the Delta-IV Heavy rocket ignited, lifting the Orion spacecraft off from Launch Complex 37B at Cape Canaveral Air Force, now Space Force, Station (CCAFS) in Florida to begin the EFT-1 mission. Three minutes and fifty-eight seconds after liftoff, the two side boosters separated as the center core continued firing for another 93 seconds. The second stage ignited thirteen seconds after separation to begin the first of three planned burns. During the first burn, the Service Module’s protective fairing separated, followed by the Launch Abort System. Lasting about 11 and a half minutes, this first burn of the second stage placed the spacecraft into a preliminary 115-by-552-mile parking orbit. While completing one revolution around the Earth, controllers in Mission Control at NASA’s Johnson Space Center in Houston, led by Flight Director Michael L. Sarafin, verified the functioning of the spacecraft’s systems. The second stage ignited a second time, firing for 4 minutes and 42 seconds to raise Orion’s apogee or high point above the Earth to 3,600 miles. During the coast to apogee, Orion remained attached to the second stage and completed its first crossing through the inner Van Allen radiation belt.
Three hours and five minutes after launch, Orion reached its apogee and began its descent back toward Earth, separating from the second stage about 18 minutes later. The second stage conducted a one-minute disposal burn to ensure it didn’t interfere with the spacecraft’s trajectory. During the passage back through the Van Allen belt, Orion fired its thrusters for 10 seconds to adjust its course for reentry. At an altitude of 400,000 feet, the spacecraft encountered the first tendrils of the Earth’s atmosphere at a point called Entry Interface, traveling at 20,000 miles per hour (mph). A buildup of ionized gases caused by the reentry heating resulted in a communications blackout with Orion for about two and a half minutes. The spacecraft experienced maximum heating of about 4,000 degrees Fahrenheit, proving the worthiness of the heat shield. After release of Orion’s forward bay cover, two drogue parachutes deployed to slow and stabilize the spacecraft. Next followed deployment of the three main parachutes that slowed the spacecraft to 20 mph. Splashdown occurred 4 hours and 24 minutes after launch about 600 miles southwest of San Diego, California.

Standing by to recover the Orion capsule, U.S. Navy Divers assigned to Explosive Ordnance Disposal Mobile Unit 11 and Fleet Combat Camera Pacific and crew members from amphibious transport dock U.S.S. Anchorage (LPD-23) stepped into action, first placing a flotation collar around the spacecraft. After securing a tow line to the capsule, the sailors towed it aboard the amphibious well deck of Anchorage, which set sail for Naval Base San Diego arriving there on Dec 8. Engineers from NASA and Lockheed Martin conducted a preliminary inspection of the spacecraft during the cruise to San Diego and found that it survived its trip into space in excellent condition.
The Orion EFT-1 mission met all its objectives and received many accolades. “Today was a great day for America,” said Flight Director Sarafin from his console at Mission Control. “It is hard to have a better day than today,” said Mark S. Geyer, Orion program manager. “We’re already working on the next capsule,” said W. Michael “Mike” Hawes, Lockheed Martin’s Orion program manager, adding, “We’ll learn a tremendous amount from what we did today.” NASA Associate Administrator for Human Exploration and Operations William H. Gerstenmaier praised all personnel involved with the EFT-1 mission, “What a tremendous team effort.” NASA Administrator Charles F. Bolden summarized his thoughts about the mission, “Today’s flight test of Orion is a huge step for NASA and a really critical part of our work to pioneer deep space.”
After its arrival at Naval Base San Diego, workers placed the Orion capsule aboard a truck that delivered it to NASA’s Kennedy Space Center (KSC) in Florida on Dec. 18. After engineers conducted a thorough inspection of the spacecraft at KSC, workers trucked it to the Lockheed Martin facility in Littleton, Colorado, where it arrived on Sept. 1, 2015. Engineers completed final inspections and decontamination of the vehicle. The KSC Visitor Complex has the capsule on display.
Orion’s second flight, Artemis I, launched on NASA’s Space Launch System on Nov. 16, 2022. During this mission, Orion reached a maximum distance of 268,563 miles from Earth, traveling farther than any spacecraft built for humans. The first in a series of increasingly complex missions, Artemis I provided a foundation for human deep space exploration and demonstrated our commitment and capability to extend human existence to the Moon and beyond. The uncrewed Orion spacecraft spent 25.5 days in space, including 6 days in a retrograde orbit around the Moon, concluding with a splashdown in the Pacific Ocean on Dec. 11, exactly 50 years after the Apollo 17 Moon landing.
We are now preparing for the Artemis II mission, in which Orion will carry a crew on a 10-day journey around the Moon in April 2026. On April 3, 2023, NASA named the four-person crew for the Artemis II mission, the first flight to take humans beyond low Earth orbit since Apollo 17 in December 1972. The crew includes NASA astronauts G. Reid Wiseman as commander, Victor J. Glover as pilot, and Christina H. Koch as a mission specialist as well as Canadian Space Agency astronaut Jeremy R. Hansen as the other mission specialist. The four will take an Orion spacecraft on a 10-day journey around the Moon to human rate the spacecraft and SLS.
