Watch NASAs next-generation moon rover crush an obstacle course

Today's Mars rovers typically drive at about 500 to 1,000 feet per hour — roughly the length of one to three football fields — and only for short stints at a time. NASA engineers say they could go so much longer and faster if they could only think more for themselves. A miniature prototype is already proving that point.
