Perseverance Expels Rock Fragments

A portion of a cored-rock sample is ejected from the rotary percussive drill on NASA's Perseverance Mars rover. The imagery was collected by the rover's Mastcam-Z instrument on Jan. 15, 2022, the 322nd Martian day, or sol, of the mission, during an experiment that oriented the drill and sample tube (unseen here) around 9 degrees below horizontal and then rotated and extended the drill's spindle. The Mastcam-Z investigation is led and operated by Arizona State University in Tempe, working in collaboration with Malin Space Science Systems in San Diego, California, on the design, fabrication, testing, and operation of the cameras, and in collaboration with the Neils Bohr Institute of the University of Copenhagen on the design, fabrication, and testing of the calibration targets. 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.
