Photos: NASA tests moon building

NASA will begin testing a two-room, inflatable building that will be a model for its planned base on the moon. It is the first generation of a building that eventually will be bustling with activities when astronauts are visiting but will be durable enough to last long periods of inactivity.

NASA plans to build a moon base that will serve as a visitor center, laboratory and stepping stone to Mars.
