The entire test flight only lasted four and a half hours. Most of that time was flight powered by the Delta IV Heavy and it's associated rockets. The Orion test capsule took 2 orbits around the earth before reaching it's peak orbit at 10:11 am (EST) and starting it's insanely fast return trip to Earth, which engineers estimate will take it to a top speed around 20,000 mph with a peak acceleration of 8.28x the force of gravity and reentry temperatures near 4,000 degrees Fahrenheit! Those are some big numbers and you can start to see why this test mission is so important if we want to eventually man these Orion capsules. Orion successfully splashed down into the Pacific Ocean at 11:29 am EST. You can see here a visual overview of the test mission:
