This December, Orion left for a 60,000 mile journey through space, to land at sea to be carried 600 miles back to shore, and finally went on a 2,500-mile road trip home. Here's the whole journey from construction through the flight and back home, in pictures.

Orion is the new NASA prototype vehicle intended for human deep space exploration. After months of tracking construction, transportation, and assembly, we were in the final countdown of excitement preparing for the first uncrewed test flight.
Launch of the Orion spacecraft on the morning of Friday, December 5, 2014.
The test flight was intended to launch on Thursday, December 4th. It faced a one-day delay due to weather and frozen valves, then took off without a hitch on Friday morning. After a beautiful test flight, it splashed down in the Pacific Ocean, was recovered, shipped home, and is undergoing analysis to learn as much as possible about everything that happened.
For a truly extensive gallery on testing and assembling the Orion prototype, you're going to want to head to this excellent feature on Rocket STEM, but here's a quick visual summary:

The launch out of Cape Canaveral was supposed to off on Thursday, but was delayed by gusting winds and cranky gear. But it launched on Friday, and was just as spectacular as we hoped:

If you're feeling totally enamoured with our deep space prototype, you can print out a paper model to construct a mini-Orion for your desk. Do you have any favourite photos from the adventure that I missed?
