A rover (or sometimes planetary rover) is a space exploration vehicle designed to move across the surface of a planet or other celestial body. Some rovers have been designed to transport members of a human spaceflight crew; others have been partially or fully autonomous robots.
To meet these needs, NASA has developed prototypes of two new rovers. One is an unpressurized lunar truck or chariot. The other is called variously the lunar electric rover (LER) or the small pressurized rover (SPR). While the original LRV was like a dune buggy, the SPR is more like an extended minivan that can traverse the moon. Recently, the SPR traversed Pennsylvania Avenue as a participant in President Obama's inaugural parade.
