Perseverance passes Opportunity to set Mars driving record of 45.22 km, mostly on autopilot
NASA's Perseverance rover reached a total of 45.22 kilometres (28.10 miles) driven on Mars on Oct 11, edging past the 45.16 km that Opportunity covered before a dust storm ended its mission in 2019, JPL robotic operations deputy team chief Mark Maimone told IEEE Spectrum in an interview published Oct 13. Perseverance drives itself about 90% of the time with its AutoNav system, which uses a second FPGA-based processor for faster image processing and runs at up to 120 metres per hour, compared with roughly 5% autonomous driving for Opportunity and Curiosity. Maimone said Anthropic's Claude drafted a starting route for one drive of about 400 metres from orbital images, which human planners checked and adjusted, and that engineers are now working on better onboard localisation and autonomous science targeting. It is the first Mars rover story in MEKAWIRE's database.
