Defence Tech links to this Boeing press release showing artist renditions of Boeing proposals for the Crewwed Exploration Vehicle.
A few thought from a laygeek. It is neat that Boeings going whole hog with inflatable space structures. I wonder about the "Lunar Space Station"....will it orbit the moon or be at a Lagrange point?
There is very little info here except the pictures and of course the obligatory speech about how Boeing is the greatest most wunderfullest company around. Still, it is really neat to see proposals so quick. :)
