The NASA Human Exploration Rover Challenge, prior to 2014 referred to as the Great Moonbuggy Race, is an annual competition for high school and college students to design, build, and race human-powered, collapsible vehicles over simulated lunar terrain. NASA sponsors the competition, first held in 1994, and, since 1996, the U.S. Space & Rocket Center hosts.
Students created vehicles dubbed "moonbuggies" to face challenges similar to those engineers at NASA's Marshall Space Flight Center addressed in preparation for Apollo 15. On that mission, on July 31, 1971, the first Lunar Roving Vehicle extended the range of astronauts on the moon to allow for further exploration than was otherwise possible. Two other rovers were sent to the moon on subsequent missions.
With the 2014 changes in the contest, the motivation changed to mimicking design challenges faced by engineers designing rovers for future exploration missions to a variety of celestial bodies.
The first race, in 1994, was held on July 16, the 25th anniversary of the Apollo 11 launch. It featured six college teams who competed on the same course as had been used to test the lunar rovers previously. The University of New Hampshire finished first, in 18 minutes 55 seconds for the 1.4-mile (2.3 km) course with twelve obstacles. The prize was a trip for six team members to see a Space Shuttle launch. Other teams from the University of Puerto Rico at Humacao, Texas A & M University, the University of Alabama in Huntsville, Georgia Institute of Technology and Indiana University/Purdue University at Indianapolis participated.
Subsequent races have been held in April. In 1996, the competition was moved to a .75-mile (1.21 km) course at the U.S. Space & Rocket Center; high school teams also began competing.
