. Perseverance Discovers a Doughnut-Shaped Rock. NASA's Perseverance Mars rover captured this doughnut-shaped rock in Jezero Crater from about 328 feet (100 meters) away using its Remote Microscopic Imager (RMI), part of the SuperCam instrument, on June 22, 2023, the 832nd Martian day, or sol, of the mission. Oddly shaped rocks aren't uncommon, either on Earth or Mars; they're often formed over eons as winds sandblast rock faces. This particular rock may have formed after a smaller rock (or multiple rocks) eroded near its center. That left behind a cavity that was later enlarged by the wind. Figure A shows the same rock in its broader context, when it was first spotted by the rover's Mastcam-Z instrument from about 1,312 feet (400 meters away) on April 15, 2023, the 765th Martian day, or sol, of the mission. SuperCam is led by Los Alamos National Laboratory in New Mexico, where the instrument's body unit was developed. That part of the instrument includes several spectrometers as well

The hole that NASA's Curiosity Mars rover drilled into target rock 'John Klein' provided a view into the interior of the rock, as well as obtaining a sample of powdered material from the rock.
