Michelin Equips NASA’s new Lunar Rover Vehicle

Michelin Lunar Wheel

Michelin is supplying a specially designed wheel for NASA’s next generation of moon rover vehicles. Featuring highly specialised materials, this engineering breakthrough will enable the lunar vehicles to maintain their mobility in extreme conditions over harsh terrain.

Made of patented composite materials, the structurally supported tyre/wheel assembly was jointly developed by Michelin’s European and North American research centres. As a result of this exclusive development, Michelin will help meet NASA’s mobility needs for manned and unmanned missions to the moon over the next decade.

Based on the Michelin Tweel®, the Michelin Lunar Wheel maintains flexibility and constant ground pressure, allowing the vehicle to move through loose soil and craters. In addition, it combines low weight and high load-carrying capacity, making it 3.3 times more efficient than the original Apollo Lunar Rover wheels. Its textile tread, developed in partnership with Clemson University and Milliken & Company, enables the rover to maintain traction at very low temperatures.

The Michelin Lunar Wheel underwent testing in Hawaii from October 31 to November 13, 2008 as part of NASA’s lunar analogue testing and evaluation program. The terrain, rock distribution and soil composition of Hawaii’s Big Island provide a high-quality simulation of the lunar polar region.

The Michelin Lunar Wheel made its debut at the 56th US presidential inaugural celebration. Astronauts aboard NASA’s latest Small Pressurized Lunar Rover prototype at the swearing-in ceremony for Obama rolled down Pennsylvania Avenue on Michelin’s non-pneumatic tyre/wheel technology.

Long-time partners, Michelin has been supplying space shuttle tires to NASA for more than 20 years.
