Perseverance Coring Bit

This image shows the back of Coring Bit 2 in the bit carousel of NASA's Perseverance Mars rover. A wavy, stringlike piece of foreign object debris (FOD) can be seen on the left side of the bit (the lower center of image). Coring Bit 2 was recently used to sample the sedimentary rock at "Wildcat Ridge." The image was obtained by the WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) camera on Aug. 17, 2022, the 531st Martian day, or sol, of the mission. Located in the turret at the end of the rover's robotic arm, WATSON can document the structure and texture within a natural (intact), drilled, or abraded target, and its data can be used to derive depth measurements. The camera is a subsystem of the SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) instrument. NASA's Jet Propulsion Laboratory built and manages operations of Perseverance and Ingenuity for the agency. Caltech in Pasadena, California, manages JPL for NASA. WATSON was built by Malin Space Science Systems (MSSS) in San Diego and is operated jointly by MSSS and JPL. 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/PIA25327
