NASA’s Perseverance rover has set a new driving record for vehicles operating beyond Earth. The six-wheeled robot has travelled 45.2 kilometres across Mars since landing in 2021. NASA announced the milestone on Tuesday, marking another achievement in its exploration of the Red Planet.
The car-sized rover has now surpassed the previous record held by NASA’s Opportunity rover. Opportunity covered approximately 45 kilometres during its mission from 2004 to 2018. Perseverance reached the milestone while exploring ancient Martian terrain for signs of conditions that could have supported microbial life.

Perseverance has focused its scientific work on Jezero Crater, located in Mars’s northern hemisphere. Scientists believe water once flooded the region and formed a lake billions of years ago. The rover reached its latest milestone while travelling towards an area known as Idubi, beyond the crater’s western rim.
NASA project manager Steven Lee said the rover’s equipment and scientific instruments remained in excellent condition. He added that recent assessments indicated its systems could continue operating well into the 2030s. NASA has also extended the mission to explore the crater rim until approximately the end of 2028.
The rover’s autonomous navigation system, called AutoNav, has played a major role in its driving success. According to Lee, about 90 per cent of its journeys occur without direct human intervention. The system creates three-dimensional maps from images and selects safe routes towards its destinations.

Perseverance has also investigated rocks that may preserve evidence of ancient microbial life. Scientists identified a potential biosignature in reddish rock formed between 3.2 billion and 3.8 billion years ago. Researchers are examining the finding to understand whether it could indicate past biological activity.
NASA originally planned for Perseverance to travel about 20 kilometres during its mission. Engineers are now testing its mobility systems for journeys of 100 kilometres or more. Its plutonium-powered energy system continues performing as expected, providing power for further exploration of Mars.
