NASA has conducted field tests with an advanced rover prototype, named ERNEST (Exploration Rover for Navigating Extreme Sloped Terrain), in the Colorado Desert, near Plaster City, California. Developed at the Jet Propulsion Laboratory (JPL), this four-wheeled vehicle is designed with enhanced mobility and robotic autonomy capabilities, and its primary objective is to serve as a testbed for autonomy software to be used in future space missions.

During the tests, conducted in March 2026, ERNEST demonstrated its ability to operate in complex and extreme terrains, simulating conditions that might be encountered on other planetary bodies. The focus of these tests is not only on the mechanical robustness of the rover but also on evaluating navigation algorithms and autonomous decision-making that allow the vehicle to operate with minimal human intervention in remote and challenging environments.
