PIXL Image of Salts in Bellegarde
NASA's Perseverance Mars rover used its PIXL (Planetary Instrument for X-ray Lithochemistry) instrument to analyze the "Bellegarde" abrasion target – created when the rover scraped away surface area of the rock named "Rochette" – revealing salt minerals (the yellow color in the image). Salt crystals could have trapped bubbles of ancient water that, after the samples are returned to Earth, scientists could use to learn more about the environment these salts formed in.
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.
JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.
