HUNTSVILLE, Ala. - NASA is updating its annual "moonbuggy" race in Huntsville.

NASA has staged the Great Moonbuggy Race for the last two decades. Student teams from all over the country and some foreign countries build rigs to race around a simulated lunar surface.

The race is being revamped, and next year it will become the "NASA Human Exploration Rover Challenge."

Students will again build vehicles, but the course will be a simulated field of asteroid debris with small boulders, a dry stream bed, pebbles and erosion ruts.

NASA says the new version of the race looks ahead to the next generation of spaceflight and the scientists needed to get people into deep space.

The challenge will be held in April at the U.S. Space and Rocket Center in Huntsville.
