Jay Leno explores how outer space has influenced car design, technology, culture, and our imagination. He and astrophysicist Neil DeGrasse Tyson head to Edwards Airforce Base to get an education in going fast - like, three times the speed of sound fast. Then he meets up with pop culture historian Charles Phoenix to discuss space's influence on design, drives the $2.5 billion Mars Rover, and challenges pal Tim Allen to a game of "Stump a Car Nerd," all to discover why space is so important to the automobiles of today.
