Rover Challenge (You can still call it Moonbuggy Race if you want)

What used to be the Great Moonbuggy Race is now the NASA Human Exploration Rover Challenge. It’s still two days of high school and college teams racing across an obstacle course, and more than 80 teams of students from around the world are here to take part. Watch the action on UStream or NASA TV. Coverage begins at 8:15AM Eastern time/7:15AM Central time.
Is it still “catching air” if you’re supposed to be on the Moon?
