I hear there's a strict helmet law on the moon.
Nasa experimented with the idea of using this mini bike on the moon instead of the Lunar Rover. This photo was taken aboard the "Vomit Comet". That's the nickname for the KC-135 aircraft that simulates zero gravity by flying in a roller coaster like manner. Somehow they were also able to simulate the 1/6 earth gravity of the moon. It appears he's jumping a small ramp.
Too bad this never progressed beyond the experimental stage. Imagine how cool it would have been to be the first bikers jamming on the moon.
