""Engineers at [Jet Propulsion Laboratory] meticulously plan each day of the rover's activities on Mars,""
""But once the rover starts driving, it's on its own and sometimes has to react to unexpected obstacles in the terrain.""
""More than 90 percent of Perseverance's journey has relied on autonomous driving, making it possible to quickly collect a diverse range of samples,""
The Perseverance rover traversed 1,350.7 feet (about a quarter mile) over 4 hours and 24 minutes during a single Martian sol on June 19, 2025, marking the longest single-sol distance for any Mars explorer. Human scientists choose the rover's destinations while the rover's navigation software autonomously charts its course and reacts to unexpected terrain obstacles. Enhanced Autonomous Navigation (ENav) can scan up to 50 feet ahead to identify hazards and plan around them. More than 90 percent of Perseverance's travels have relied on autonomous driving, and navigation cameras captured images every 16 feet then every 3.3 feet, with virtual frames reconstructed from the rover's data.
