This animation of NASA’s Perseverance was created with the Caspian visualization tool using data acquired during an 807-foot (246-meter) drive on the rim of Jezero Crater made by the rover on Dec. 10, 2025, the 1,709th Martian day, or sol, of the mission. The mission’s “drivers,” or rover planners, use the information to understand the Perseverance’s autonomous decision-making process during its drive by showing why it chose one specific path over other options.
This was one of two drives, the first being on Dec. 8, in which generative artificial intelligence provided the route planning. The AI analyzed high-resolution orbital imagery from the HiRISE (High Resolution Imaging Science Experiment) camera aboard NASA’s Mars Reconnaissance Orbiter and terrain-slope data from digital elevation models to identify critical terrain features — bedrock, outcrops, hazardous boulder fields, sand ripples, and the like. From that analysis, it generated a continuous path complete with waypoints, fixed locations where the rover takes up a new set of instructions.
The pale blue lines depict the track the rover’s wheels take. The black lines snaking out in front of the rover depict the different path options the rover is considering moment to moment. The white terrain Perseverance drives onto in the animation is a height map generated using data the rover collected during the drive. The pale blue circle that appears in front of the rover near the end of the animation is a waypoint.
NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech, built and manages operations of the Perseverance rover.
