One of the
rocks examined by Sojourner, the small robot cart deployed on Mars in 1997.
Note the rounded texture of some parts of the rock and the small pits. These
suggest that the rock formed from smaller pebbles rounded by erosion from
flowing water. Heating later fused the pebbles into the rock we see. (Courtesy
