Thanks, Yuppie and Sita! I have a friend who kept telling me, "Sooner or later, the universe will give you a break!" It looks like the universe decided I had earned a really big break!
No worries, Mike. The Constellation program is not classified so folks working on it can talk about their work fairly freely. Propriety is a greater concern than proprietary. I've been looking for information on it on the public web and it seems to be pretty sparse; but then, the program is just getting started. Heck, NASA awarded the contract to build the Ares I upper stage just this week.
As for the EVA project, I do know that the requirements are not fully defined. The scenario for EVA changes depending on the mission. Orion will be used to transport crew to and from the ISS as well as to the moon. The EVA scenarios are different. If it's going to the ISS, Orion doesn't really need EVA capability because it can the space station's resources. Going to the moon is rather a different issue.
It must be time to dust off this old plaque!
