Lunokhod-1, Soviet Lunar Remote-Controlled Rover, delivered to our primary satellite in 1970, by the Soviet Luna-17 space craft.
Just think of it, this is a radio controlled car designed and built in the SIXTIES! Marvelous piece of soviet construction. So good, that the designers were pulled out of retirement to help with the Chernobyl nuclear accident, producing Lunokhod rover based remote bulldozers.
Forget Curiosity, and the forgotten Spirit and Opportunity rovers, this guy is best rover.
