English: This video shows NASA's Perseverance Mars rover using its auto-navigation, or AutoNav, technology to drive 548 feet (167 meters) on Sept. 12, 2021, the 200th Martian day, or sol, of the mission. AutoNav allows the rover to autonomously re-plan its route around rocks or other obstacles on its way to a pre-established destination. The video was taken by the rover's navigation cameras; they are capable of color, but black-and-white images are better for navigation. The video has been sped up by roughly 200 times with roughly 30 seconds between frames.
In total, the rover drove 574 feet (175 meters). The first 26 feet (8 meters) were based on commands sent up earlier by rover drivers, allowing Perseverance to build a 3D map of the terrain under and around it. This map allows the AutoNav function to assess the safety of available paths at the rover's location; engineers call this "crawling on to the map." Once AutoNav takes over, the rover autonomously chooses a path to reach the intended destination, continually imaging around itself to maintain a 98-foot-by-98-foot (30-meter-by-30-meter) map centered on the rover. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust). Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis. The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet. JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance rover. |
