A Research Drone in Front of Mars Hill

This is one of three research drones that NASA’s Jet Propulsion Laboratory in Southern California used in September 2025 to test navigation software that could be used by future rotorcraft on Mars. The drone is sitting in front of a location within Death Valley National Park called Mars Hill, which is littered with rubbly volcanic rocks and has been used by NASA’s Mars researchers since the 1970s, during preparations for the Viking lander missions. The work was among 25 projects funded by NASA’s Mars Exploration Program this past year to push the limits of future technologies. Sand dunes confused the navigation algorithm of the Ingenuity Mars helicopter during several of its last flights, including its 72nd and final flight on the Red Planet in January 2024. The navigation software in development would help future rotorcraft to track the surface of especially bland, featureless terrain similar to the barren sand dunes seen in parts of Death Valley and to land safely in cluttered environments like Mars Hill.
