Photograph of tan rock with two diagonal veins of lighter rock on either side. In the tan rock are several small, irregular spots of sand-colored rock ringed with dark bluish-greenish rock. These spots’ chemical composition was studied and found to contain minerals that, given Mars’s expected environment billions of years ago, could have been produced by microbes.
