2 Perseverance Sampling Locations in Jezero's Delta

This image shows two locations in Mars's Jezero Crater where NASA's Perseverance rover collected rock samples for possible return to Earth in the future: "Wildcat Ridge" (lower left) and "Skinner Ridge" (upper right). These two outcrops are within about 70 feet (20 meters) of each other. The rover cored two cylinders of rock the size of classroom chalk (about 0.5 inches, or 13 millimeters, in diameter and 2.4 inches, or 60 millimeters, long) from each location. The two sites are in the delta, a fan-shaped area where, billions of years ago, a river once flowed into a lake in Jezero Crater and deposited rocks and sediment. Scientists consider the sedimentary rocks preserved in the delta one of the best places on Mars to search for potential signs of ancient microbial life. The verification of ancient life on Mars carries an enormous burden of proof. A light-colored, circular patch of abraded rock can be seen in the lower-left corner of the image, next to areas where Perseverance used its drill to extract the rock-core samples. The abrasion patch to the right of one of the holes is about 2 inches (5 centimeters) in diameter. The samples taken from these areas were sealed inside ultra-clean sample tubes, which are currently stored inside Perseverance. The multiple images that make up this mosaic were acquired by Perseverance's Mastcam-Z instrument on Aug. 4, 2022, the 518st Martian day, or sol, of the rover's mission. The color bands of the image have been processed to improve visual contrast and accentuate color differences. 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/PIA24924
