Overview
- Perseverance, which hit the milestone on 11 October 2026, has driven 45.22 kilometers and now exceeds Opportunity's 45.16 kilometer total.
- NASA says more than 90 percent of that distance was traveled autonomously by the rover's AutoNav system, which uses onboard cameras to map terrain and steer around hazards.
- A February 2026 Mars Global Localization upgrade lets Perseverance self‑locate to roughly 25 centimeters by matching navigational camera views to orbital maps, enabling longer, more confident drives without frequent Earth commands.
- Mission managers started a first extension in October 2026 that runs roughly to the end of 2028 after mobility tests showed the rover's drive systems remain healthy, allowing planners to target distant sites such as Idubi for additional sampling.
- Operational limits remain: bright sun glare can blind the navigation cameras and force afternoon stops, so engineers are tuning software and procedures to increase usable driving hours.
