A mockup of NASA's next generation moon rover, the Space Exploration Vehicle (SEV), on display at the agency's Johnson Space Center in Houston. The SEV has since been converted into a wheel-less vehicle designed for visiting asteroids.

The bubble-fronted SEV rover version was optimized for wheeling around on the moon. The crew cabin part has lately been converted into a vehicle that can be attached to a sled for visiting asteroids.

This version of the SEV sled is in the very preliminary stages of development. Soon, engineers will experiment with it on an air hockey table-like floor that allows it to move without friction in two dimensions.
