The rock must be fairly distant from the lander because its image is only about 10 by 20 pixels. They look like lichens. All very interesting. It's clear we should go back for another look. One interesting speculation that I had about this -- if there is life on Mars, it's quite possible it came from Earth. Since material from Mars is believed to have traveled to the earth and landed in Antarctica (by being blasted from Mars by a meteor impact and eventually intersecting the earth's orbit), the reverse is also possible. I wonder if the spores of ancient microorganisms would be capable of surviving the voyage (suitably encased or shielded by rock)..
