This graph shows two spectra of outcrop regions
near the Mars Exploration Rover Opportunity's landing site. The blue line
shows data for a region dubbed "Berry Bowl," which contains a handful of
the sphere-like grains dubbed "blueberries." The yellow line represents
an area called "Empty" next to Berry Bowl that is devoid of berries.
Berry Bowl's spectrum still shows typical outcrop characteristics, but
also exhibits an intense hematite signature, seen as a "magnetic
sextet." Hematite is an iron-bearing mineral often formed in water.
These spectra were taken by the rover's Moessbauer spectrometer on the
46th (Empty) and 48th (Berry Bowl) martian days, or sols, of its mission.
