On October 11, NASA's Perseverance rover completed a drive that brought its total distance on Mars to 28.10 miles (45.22 km), a new record for Mars rovers. IEEE Spectrum says this was enabled largely by Perseverance's ability to drive with much more autonomy than earlier rovers.
Its autonomy software has been upgraded steadily over five years. Spectrum spoke with NASA JPL's Mark Maimone, who designed the self-driving software.
