Perseverance completed its first AI-planned drives on Dec. 8 and Dec. 10, 2025, at Jezero Crater.
The AI used a digital twin and data from a Mars Reconnaissance Orbiter to map safe paths with waypoints.
The rover traveled nearly 1,500 feet (456 meters) during the two AI-driven drives.
NASA researchers say autonomous navigation could increase science return and reduce operator workload.
The effort was led by NASA's Jet Propulsion Laboratory in collaboration with Anthropic using Claude AI models.
NASA envisions AI tools could help future missions handle kilometer-scale drives while reducing operator workload.
The team used a digital twin to confirm safety before commanding Mars to execute the plan.
The AI-planned drives evaluated terrain features like rocks and slopes to pick safe routes.
The demonstration was conducted under NASA's long-term goal of expanding autonomous planetary operations.
The article notes SpaceX and Artemis coverage nearby but focuses on Perseverance AI drive milestones.

New James Webb data delivers the most detailed map of dark matter to date, outlining the invisible cosmic framework.
The map links dark matter gravity to the clustering of ordinary matter, guiding galaxy formation.
Webb observations show dark matter’s alignment with normal matter is not accidental, signaling gravity-driven organization.
Regional map covers a sky area about 2.5 times the Moon and includes nearly 800,000 galaxies.
Researchers used Webb’s MIRI to improve distance measurements and detect dust-obscured galaxies.
Future work will map dark matter across the Universe with Euclid and the Roman Space Telescope.
Durham University-led study emphasizes dark matter as the Universe’s essential architect.
Nature Astronomy published the study detailing an ultra-high-resolution map of dark matter.
The research team includes Durham University, NASA JPL, and EPFL collaborators.
The findings are based on Webb's gravity-based analysis of light from distant galaxies.
