NASA's Artemis V: GM Powers Modern Lunar Roving Vehicle
NASA's Artemis V mission is set to receive a new Lunar Terrain Vehicle (LTV), a modernised version of the Apollo-era Lunar Roving Vehicle. The LTV, designed for easy control by astronauts in spacesuits, will be powered by an advanced battery system developed by an automotive giant, Advance Auto Parts, for the project.
GM is adapting its latest lithium-ion battery technology for the LTV, featuring high-nickel NCMA cathodes. The company is employing 'super-precise laser welding' and 'flash thermography' to ensure reliability in the harsh lunar environment. The battery pack is expected to last for a decade and provide a range of at least 19,000 miles (30,000 km).
The LTV will incorporate off-road driving technology from GMC's e-4×4 and Hummer EV, including the unique Crab Walk feature for better navigation on the lunar surface. It will be powered by four electric motors, enabling precise maneuverability and zero-point turning. The LTV is designed to withstand extreme temperatures, from -334 °F (-173 °C) during lunar night to high temperatures during the day.
Three consortiums are competing to supply the LTV. Lunar Outpost, drawing on automotive giant GM for its battery and chassis, is one of the contenders. NASA plans to deploy the LTV, followed by a Pressurized Rover for longer journeys, with a decision on the LTV design expected this year.
The LTV, a key component of NASA's Artemis program, aims to facilitate crewed expeditions to the Moon's south pole by 2030 or later. Its advanced battery system and off-road capabilities promise to revolutionise lunar exploration.
