First Mineral Map of a Mars Landscape was produced by the Mini-TES instrument on the Opportunity Rover, directed by ASU geologist Philip Christensen. The colors indicate relative quantities of the important mineral hematite — the red areas are high in hematite, the blue and green areas are low. Interesting to scientists, the bounce marks left by the lander's balloons are blue or green, indicating that the balloons pushed the hematite into the underlying dust. Christensen's image is the first on-site mineral map ever made on Mars, and gives mission scientists critical information they need to study the site.
