As NASA's Artemis missions approach, astronauts returning to the Moon will be equipped with a human-rated Lunar Terrain Vehicle (LTV) to enhance their exploration of the lunar surface. The unpressurized rover will play a key role in enabling diverse scientific research and discoveries.

At NASA's Johnson Space Center in Houston, engineers are developing a prototype for the rover, known as the Ground Test Unit (GTU). This prototype will help test and evaluate various rover concepts, laying the groundwork for the Lunar Terrain Vehicle that will be deployed starting with Artemis V.

In April 2024, NASA selected Intuitive Machines, Lunar Outpost, and Venturi Astrolab through the Lunar Terrain Vehicle Services (LTVS) contract to supply rover technologies for future Artemis missions. While the GTU will not travel to the Moon, it is crucial for the development of subsequent prototypes, allowing both NASA and the contracted companies to refine their designs. The GTU will serve as an engineering testbed to examine aspects such as crew compartment design, rover maintenance, and the integration of scientific payloads.

"The Ground Test Unit will help NASA teams on the ground, test and understand all aspects of rover operations on the lunar surface ahead of Artemis missions," explained Jeff Somers, engineering lead for the Ground Test Unit. "The GTU allows NASA to be a smart buyer, so we are able to test and evaluate rover operations while we work with the LTVS contractors and their hardware."

The LTVS contractors' requirements align with the GTU's capabilities. Like the GTU, the LTV must support up to two astronauts, be remotely operable, and offer a variety of control modes such as self-leveling and supervised autonomy. The presence of a NASA prototype here on Earth allows teams to gain practical experience in developing rover technologies.

NASA's progress builds on the agency's previous successes with lunar vehicles, including the Apollo Lunar Roving Vehicle from the 1970s. As testing continues, these Earth-bound prototypes will help ensure that astronauts can safely and productively work on the Moon - and eventually on Mars. By testing these technologies early, NASA mitigates risks before actual lunar missions begin.

Human surface mobility is essential for expanding exploration on the lunar surface, enabling missions to conduct more extensive research and enhancing the value of their scientific contributions. Through Artemis, NASA plans to send a diverse group of astronauts to explore the Moon, laying the groundwork for future crewed missions to Mars.
