This wonderful Mastcam-Z image, in addition to showing us a clear view of the rover’s front left wheel, shows rocks peppered with holes. Geologist Kathryn Stack Morgan, deputy project scientist for the Mars 2020 mission, said similar holes are seen in volcanic rocks, but also sedimentary rocks. The team is keen to find out, as the result will be interesting regardless.
