The Orion spacecraft sits inside the Launch Abort System Facility at NASA’s Kennedy Space Center in Florida awaiting its rollout to the launch pad Monday night. The spacecraft will be moved to Space Launch Complex 37 at Cape Canaveral Air Force Station for its flight test, flying aboard a United Launch Alliance Delta 4-Heavy rocket.

Mike Sarafin, NASA’s lead Orion flight director, narrates animation depicting the Exploration Flight Test 1 from liftoff aboard a United Launch Alliance Delta 4-Heavy rocket to splashdown in the Pacific Ocean.

Boosted to an altitude of 3,604 miles by a Delta 4 rocket, NASA’s Orion deep space exploration vehicle fell back to Earth Friday in the program’s maiden voyage, slamming into the atmosphere at nearly 20,000 mph, enduring a hellish 4,000-degree re-entry and settling to a Pacific Ocean splashdown to wrap up a critical unmanned test flight.
