GM Defense will supply battery-electric propulsion for NASA’s Artemis 2029 Pegasus Lunar Terrain Vehicle, designing the high-capacity battery for a 2028 moon rover mission. The battery enables over 9 mph driving for up to a year and can survive 14-day lunar nights at –334°F.
GM Defense has secured a subcontract under NASA’s Artemis program to supply battery-electric propulsion for the Pegasus Lunar Terrain Vehicle. The subsidiary will work alongside prime contractor Lunar Outpost and partners Goodyear, MDA Space and Leidos to integrate its propulsion system for the Eagle rover.
The high-capacity battery design targets speeds above 9 mph and continuous operation for up to one year on the lunar surface. It is engineered to withstand 14-day lunar nights at temperatures down to –334°F and focuses solely on propulsion after Lunar Outpost took over suspension and autonomous hardware roles.
The battery is slated for use on a 2028 moon rover mission and will support sustained operations beginning with the Artemis 2029 mission. Potential deployment could extend into 2030, reflecting GM Defense’s long-standing expertise in developing technology for extreme space environments.
