Google's Lunar XPRIZE offers a $30 million prize for the first team to get a rover to the moon, cover 500 meters of it, and broadcast high-definition video back to Earth as it goes. The aim is to challenge engineers and scientists around the world into develop low-cost (robotic) ways of exploring space. Part-Time Scientists have already picked up two "milestone" prizes during the development of its rover -- but the clout of Audi is more than likely to help it reach the moon. Audi's concept design studio in Munich is apparently already revising the design of the rover to ensure "ideal lightweight construction conditions." In this competition, there's no points for style.
