PIXL Instrument on NASA's Perseverance Studies 'Ouzel Falls'

Before collecting a rock sample at a spot nicknamed "Otis Peak," NASA's Perseverance Mars rover employed an abrasion tool to wear down the rock surface and then used the Planetary Instrument for X-ray Lithochemistry, or PIXL, to study the rock's internal chemistry. This image of the abrasion patch, dubbed "Ouzel Falls," was taken in May 2023 by WATSON (Wide Angle Topographic Sensor for Operations and eNgineering), a camera that is part of an instrument called Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals, or SHERLOC, on the end of the rover's robotic arm. Data from PIXL is laid over the image. Colored squares show different areas where PIXL's X-ray beam scanned the rock's surface. The instrument's data found the rock was rich in phosphate, a material found in the DNA and cell membranes of all known life, and which also serves as a way to store and transfer energy within living things. The Ouzel Falls scan areas contain a rich diversity of other mineral grains, including igneous minerals transported as sand and pebbles, such as olivine and spinel, and minerals crystallized from water, such as carbonates, clays, and sulfates. Each of these record unique aspects of the magmatic, climatic, and paleoenvironmental history of the ancient lake within Jezero Crater and the surrounding region. This diversity will make the Otis Peak sample a treasure trove for scientists on Earth who may study it in the future. 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/PIA26206
