Perseverance rover hightails it to Martian delta NASAJPL
This delta is one of the best locations on Mars for the rover to look for signs of past microscopic life. Using a drill on the end of its robotic arm and a complex sample collection system in its belly, Perseverance is collecting rock cores for return to Earth—the first part of the Mars Sample Return campaign.
But first, Perseverance needs to get there. The rover will do this by relying on its self-driving AutoNav system, which has already set impressive distance records. While all of NASA's Mars rovers have had self-driving abilities, Perseverance has the most advanced one yet. Some drives require more human input than others. AutoNav is useful for drives over flat terrain with simple potential hazards—for instance, large rocks and slopes—that are easy for the rover to detect and work around.AutoNav reflects an evolution of self-driving tools previously developed for NASA's Spirit, Opportunity, and Curiosity rovers. What's different for AutoNav is"thinking while driving"—allowing Perseverance to take and process images while on the move.
