On their kite boards, Google founders Larry Page and Sergey Brin are adept at defying gravity. But they experienced an altogether different feeling of weightlessness at Space Camp in Hunstville, Ala. Here, they played with NASA-developed training equipment, which demonstrates how your body feels during a launch and what it's like to walk on the moon. Huntsville is, in fact, the birthplace of the space program and the Saturn V rocket. Brin and Page were required to learn complex crew and operational systems and prepare for a simulated shuttle mission. Over and over, they were placed in simulated (yet still very stressful) life-or-death situations. In one exercise, they were sent on an emergency shuttle "mission" to rescue a damaged satellite. There was even a mock press conference afterwards where Space Camp employees fired off questions.
