NASA’s Perseverance rover spots a pair of funky Mars rocks shaped like a shark fin and a crab claw due to erosion.
. The Jezero Crater is even home to an ancient river delta. Water is an excellent sculptor of rocks, but the planet’s winds also carve up the local geology. “The abrasion process can form flutes, pits, and grooves in rocks, leading us to see peculiar illusions in their shapes and shadows,”Perseverance captured the rocky view with one of its mast-mounted cameras. These cameras are located on the “head” of the car-sized rolling machine and are equipped with powerful zoom lenses.
Scientists have yet to find proof of life—present or past—on Mars. But they’re looking. One of Perseverance’s big tasks is to seek out evidence of ancient microbial life on the red planet. It’s not equipped to make a definitive discovery on its own, so it’s collecting rock samples and stashing them in tubes on the Martian surface. NASA hopes to retrieve some of the rover’s rock collection via the ambitiousmission and bring those precious tubes to Earth for closer study.
Today, Mars is inhospitable. Perseverance is built to withstand rough conditions, from dust storms to rugged terrain to frigid temperatures. One thing it won’t have to worry about, though, is shark attacks. As far as we know, sharks are a distinctly Earth animal.
