IEEE Spectrum reports in a Q&A that the Perseverance rover has set a new distance record for Mars rovers.
On 11 October, Perseverance completed a drive that brought its total distance on Mars to 28.10 miles (45.22 kilometers). The record is enabled in large part by its ability to drive with much more autonomy.
