Any good article about space exploration starts with "when I was a kid...". So, when I was a kid, my older brother was working on his college thesis. He cooperated with NASA on designing various devices for use in space, the basic premise being that few of the things we take for granted here on Earth would work in a zero-gravity environment. Everything needed for use in space needs to be redesigned.
Recently Goodyear and NASA announced a collaboration in developing a special non-pneumatic tire to be used by vehicles on the Moon, and potentially, on Mars, in support of a 2004 presidential mandate to further exploration on the celestial bodies. This isn't the first time Goodyear has collaborated with NASA to develop special moon-tires, having spent over ten years developing a piano-wire-mesh tire for the Apollo Lunar Roving Vehicle in the 1960s. However, the new Chariot vehicle (pictured above) is expected to support ten times more weight and travel 100 times longer than the Apollo, so Goodyear's Akron Technical Center and NASA's Glenn Research Center are developing a stronger version by testing and re-testing the Apollo's wheel and tire set-up to determine where they break down. Better here than out there, because as big a pain as it is to change a tire down here, imagine mounting a spare in space.
The researchers expect to demonstrate the Chariot, with its special tires, a year from now at the Johnson Space Center in Texas, after which, they say, the findings could be applied towards the development of new tires for use here on Earth.
