The NASA RFP is actually a nice primer on AR, if you are not quite ready to deliver on the project. You got to wonder why every AR man and his dog isn’t going after this because this has got to be best ad for your technology that could ever be created. Heck, you don’t even have to make it to the moon, it’s been a while since anyone went up there, just build a prototype for NASA and say, we’re saving it for Mars.
