NASA (and I) started work on Orion in early 2004. Those early design activities for the Vision for Space Exploration, and then Constellation, from 2004 to 2006, were a great deal of fun to work on, and I still have a lot of good memories of them.
Over ten years later, Orion is set to fly on a test flight in December 2014. NASA has a site up where you can print your own boarding pass, so your name can fly on the test flight.
