Mars Rover Peseverance Has Picked up a Hitchhiking Rock

Four months ago, NASA's Mars rover Perseverance picked up a "pet rock," tucked inside its left front wheel, that's been riding along ever since. Space.com reports:So far, its ridden across 5.3 miles (8.5 kilometers) with the Perseverance rover as it drives across its Jezero Crater home on Mars. Perseverance has carried the rock north across its landing site, named for the famed late science fiction author Octavia E. Butler, and then west across a region called "Kodiak," the remains of a former delta at Jezero. The rover is currently in the midst of what NASA calls its Delta Front Campaign and may have drilled into its first sedimentary Mars rock, Ravanis wrote. "Perseverance's pet rock is now a long way from home," Ravanis wrote. "It's possible that the rock may fall out at some point along our future ascent of the crater rim. If it does so, it will land amongst rocks that we expect to be very different from itself." If that happens, a future Martian geologist might be a bit confused to find the rock so out of place, Ravanis added.
