Perseverance Workspace at Skinner Ridge

NASA's Perseverance rover puts its robotic arm to work around a rocky outcrop called "Skinner Ridge" in Mars' Jezero Crater. Composed of multiple images, this mosaic shows layered sedimentary rocks in the face of a cliff in the delta, as well as one of the locations where the rover abraded a circular patch to analyze a rock's composition. The delta is an area where, billions of years ago, a river once flowed into a lake in Jezero Crater and deposited rocks and sediments in a fan shape. Scientists consider the delta one of the best places on Mars to search for potential signs of ancient microbial life. The verification of ancient life on the Red Planet carries an enormous burden of proof. The multiple images that compose this mosaic were acquired by Perseverance's Mastcam-Z instrument between June 30 and July 8, 2022 (PDT), the 484th and 492nd Martian days, or sols, of the rover's mission. The color bands of the image have been processed to improve visual contrast and accentuate color differences. In the days after this mosaic was taken, Perseverance also extracted two classroom chalk-size pieces of rock (cylinders about 0.5 inches, or 13 millimeters, in diameter and 2.4 inches, or 60 millimeters, long) from Skinner Ridge and sealed them in ultra-clean sample tubes. 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. https://photojournal.jpl.nasa.gov/catalog/PIA24925
