The USS Anchorage is in position off the coast of California, ready to retrieve Orion when it splashes down around 11:30 am ET.
"All of its systems are performing to perfection," NASA says. Orion passed through Van Allen radiation belt with no impact to its on board electronics.
Orion will travel from 20,000 mph to a speed of just 20mph at the time of splashdown in the Pacific, which is expected around 11:30 ET.
Here's some crazy perspective: Orion's altitude is the distance from the Florida Keys to Bangor Maine, ROUND TRIP!
Orion is now flying free. Just 57 minutes until splashdown. NASA is expecting a near "bulls eye" landing.
The farther you go, the faster you get, the hotter it is during re-entry. For this unmanned test, Orion will experience temperatures twice as hot as molten lava.
How do you slow down a capsule hurtling back to Earth at 20,000 mph? Along with some maneuvers, 11 parachutes help do the trick.
Next milestone: A 10-second firing of Orion's thrusters. This will help make sure the capsule is oriented in the best possible way for re-entry. Orion is currently flying at 1,643 statute miles over the Pacific Ocean.
Orion is now 400 miles above the Earth. It won't be long until splashdown!
Orion is going through a brief loss of telemetry, which NASA anticipated. The capsule is at the point right now where it will be reaching its peak heating.
Orion is traveling at a velocity of 84 percent of the speed of a spacecraft returning from the moon.
Connection is re-established, blackout over. Just seven more minutes until splashdown.
Just 15,000 feet until splashdown.
The main shoot is out and we can now see Orion coasting down toward the Pacific Ocean. What a moment.
The conditions couldn't be more perfect for Orion's splashdown. One thousand feet left for "America's new spacecraft."
Splashdown confirmed! 11:29 am ET. Orion is stable and upright. Next step: Recovery.
What's next? The USS Anchorage will now recover Orion from the Pacific Ocean. NASA and engineers at Lockheed Martin will analyze the data from Orion's maiden voyage. It's another step closer to a manned mission to Mars.
Two of the three main parachutes have been recovered.
What a day! Thanks for following along with us. Check back soon to ABCNews.com for a full photo recap on Orion's picture perfect journey.
