NASA sure loves vehicles , and the agency is mighty proud of its latest effort, the Chariot lunar truck. Designed from start to finish in just a year, the Chariot features 12 wheels driven by two electric motors through a two-speed transmission, allowing it to perform in a "bulldozer" mode with up to 4000 pounds of force or cruise at up to fifteen miles an hour. The modular design also means that the steel alloy frame can be fitted with several different crew / payload combinations, including a small pressurized cabin and a sample collector. There's no telling when the Chariot might be deployed, of course, but we're not going to be convinced until we see it stop a plane or drive through a swinging girder obstacle course.[Thanks, xenocide]
