Michelin Develops Lunar Wheel for NASA Moon Rover Vehicles
GREENVILLE, S.C., Nov. 13 /PRNewswire/ -- Michelin has developed a new
lunar wheel for the next generation of NASA moon rover vehicles. The
structurally supported tire and wheel assembly, made of breakthrough composite
materials, was jointly developed at Michelin's European and North American
research centers. This unique innovation will help Michelin meet NASA's
mobility challenges for manned and un-manned moon missions planned for the
coming decade.

"Michelin has partnered with NASA for more than 20 years to provide tires
for the space shuttle, and now we are taking our involvement a step further in
support of the next generation of space exploration," said David Stafford,
chief operating officer of Michelin Americas Research Company. "This project
demonstrates Michelin's ability to engineer advanced technology that meets the
mobility needs of the world's most demanding customers, including NASA."
Based on the award-winning MICHELIN TWEEL(R) assembly, the MICHELIN Lunar
Wheel maintains flexibility and constant ground contact pressure that enables
moon rovers to traverse loose soil and lunar craters. The MICHELIN Lunar Wheel
has a low mass yet maintains a high load capacity that is 3.3 times more
efficient than the original Apollo Lunar Rover wheels. The wheel structure,
developed by Michelin, employs Michelin-patented composite materials. Its
textile tread, developed in conjunction with Clemson University and Milliken &
Company, enables moon rovers to maintain traction at very low temperatures.
"This new technology not only applies to lunar missions, but may also be
directly leveraged into other mobility applications requiring light-weight and
low rolling resistance," said Stafford. "It's an exciting advance for mobility
in space and here on Earth."
Funded in part by a grant from NASA's Innovative Partnership Program, the
MICHELIN Lunar Wheel will be featured on the Scarab Rover, a lunar robot
designed by Carnegie Mellon University, in cooperation with NASA's Exploration
Technology Development Program for its In-Situ Resource Utilization project.
Equipped with a drill designed to cut through layers of lunar soil, the Scarab
Rover is capable of operating in continual darkness and extremely cold
temperatures with little power. Michelin has also developed a lunar wheel for
the ATHLETE Rover, a six-limbed lunar rover capable of transporting cargo over
any terrain to aid NASA in the assembly of the lunar outpost.
"Michelin's team of scientists and engineers worked closely with our
design team to create a solution that addresses the unique challenges of lunar
exploration," said Jaret B. Matthews, NASA's principal investigator for the
development of the MICHELIN Lunar Wheel. "The MICHELIN Lunar Wheel
successfully exceeds our initial design targets."
The MICHELIN Lunar Wheel will undergo field-testing on the Scarab Rover in
Hawaii from Oct. 31 through Nov. 13, 2008 as part of a NASA Lunar Analogs
testing and evaluation event. The terrain, rock distribution and soil
materials ofHawaii's Big Island provide high-quality simulation of the lunar
polar region.
Dedicated to the improvement of sustainable mobility, Michelin designs,
manufactures and sells tires for every type of vehicle, including airplanes,
automobiles, bicycles, earthmovers, farm equipment, heavy-duty trucks,
motorcycles and the space shuttle. The company also publishes travel guides,
hotel and restaurant guides, maps and road atlases. Headquartered in
Greenville, S.C., Michelin North America ( www.michelin-us.com ) employs more
than 22,300 and operates 19 major manufacturing plants in 17 locations.
