This was one of the first images of the sulfate-rich outcrops on the Meridiani Plains of Mars to show a broken spherule, or “blueberry” (below center). The spherules do not deflect the crosswise layers of finer sediments, indicating that the spherules and sediments were not deposited at the same time. The image shows a 3-centimeter (1.2-inch) square section of the rock Robert E in Eagle Crater.
