What Happened
On December 8 and 10, 2025, NASA's Perseverance rover received commands written not by a human, but by an AI πΈ
Anthropic's Claude planned a ~400-meter route through a rocky Martian terrain. The rover drove it successfully.
Why It's Hard
A signal from Earth to Mars takes ~20 minutes. No micromanagement β you plan a route, send it, and hope everything goes right.
Until now, JPL engineers manually placed waypoints using satellite imagery and rover camera photos. One mistake and the rover gets stuck forever β like Spirit did in 2009.
How Claude Did It
Context β JPL engineers fed the model years of accumulated driving data and expertise
Vision β Claude analyzed overhead orbital images of the Martian surface
Code β the model wrote commands in Rover Markup Language, a custom XML-based language for Mars rovers
Iteration β Claude critiqued and refined its own waypoints, assembling the route in 10-meter segments
The route was then run through simulation: 500,000+ variables β rover position, slopes, hazards. Engineers made minimal tweaks β and sent the plan to Mars.
The Result
Planning time cut in half β more drives, more science, more discoveries
400 meters is one lap around a track. But it's the first lap an AI ever planned on another planet.
What's Next
Artemis β humans back on the Moon, a base at the south pole
Deep space β autonomous probes where signal delay stretches to hours and energy is precious
Oceans under ice β Europa, Titanβ¦ worlds where a probe must decide on its own, with no help from Earth
One Fact
The same Claude that helps people write emails, build apps, and analyze finances β is now helping humanity explore other worlds.
From inbox to Mars. One model.
