Slide Show: Students Gear Up for NASA's Annual Moon Buggy Race

THE ORIGINAL (CIRCA 1971): The Great Moonbuggy Race at NASA's Marshall Space Flight Center challenges high school and college students to engineer a rover under some of the same restrictions the space agency faced when building the original in the 1960s. Moon buggy rovers must first fit into a cube with four-foot (1.2-meter) sides, roughly the same dimensions in which the original lunar rover needed to fit for travel to the moon.
