10 NASA space technologies that may never see the cosmos

NASA has robots, rockets, inflatable homes and lots of other advanced technology that may never lift off.

Lunar Electric Rover: This sophisticated moonbuggie is a pressurized vehicle about the size of a pickup truck -- with 12 wheels and can carry two astronauts for up to 14 days with sleeping and sanitary facilities, NASA claims. It is designed to require little or no maintenance, be able to travel thousands of miles climbing over rocks and up 40 degree slopes during its 10-year life exploring the harsh surface of the moon.
