Anthropic’s Claude AI has done something groundbreaking: it helped plan a route for NASA’s Perseverance rover on Mars. Last month, Perseverance traveled about 400 meters using a path created by Claude, with the support of engineers at NASA’s Jet Propulsion Laboratory (JPL).
Navigating Mars is tricky. Rovers can easily get stuck, as shown by the Spirit rover incident in 2009. Engineers at JPL typically take time to plan routes using images from Mars’s surface and orbit. They send this information 140 million miles to the rover, which then follows the plan. Driving in real-time isn’t an option due to the vast distance.
Perseverance has an AutoNav system that allows it to make on-the-fly adjustments if obstacles come up. However, much of this planning is time-consuming. That’s why JPL let Claude take charge of route planning. Claude analyzed high-resolution images and terrain data, identifying key features like rocks and sand dunes. Using this info, it generated a detailed path with specific waypoints.
Claude created commands in Rover Markup Language (RML), which is based on XML. Although there were hiccups in Claude’s understanding of RML initially, once it had access to NASA’s data, it successfully generated the necessary commands. The human engineers carried out checks and made small adjustments, ensuring the rover took a safe path.
On two Martian days—December 8 and December 10, 2025—Perseverance followed the AI-generated routes. NASA’s images show that while the rover didn’t strictly follow the path, it was influenced by Claude’s planning, with adjustments made through its AutoNav system. This real-time adaptability highlights how far AI technology has come in space exploration.
Interestingly, NASA Administrator Jared Isaacman commented on the potential of AI in future missions. He noted that using autonomous technology can enhance efficiency and improve data collection as we explore farther into space.
According to JPL, Claude could halve the route planning time, although specific numbers weren’t provided. This advancement opens the door to smarter exploration on Mars and beyond.
In the rapidly changing landscape of space exploration, AI will play a significant role in how we navigate new worlds. As technology continues to improve, systems like Claude will likely reshape our understanding of space.”
