NASA unveils lunar rover

Two teams of one astronaut and one geologist each have been driving the rover through the Arizona desert, trying it out in two different configurations. One configuration leaves the crew members free to get on and off the rover whenever they like, but they must wear spacesuits at all times to protect them from the lunar environment. The second configuration called the Small Pressurized Rover, or SPR adds a module on top of the rover’s chassis that the crew can sit inside as they drive the vehicle, donning spacesuits whenever they want to get out. The battery powered rover can move at a speed of 10kmph, and cover 625 miles of ground on a single charge.
