The Compact Reconnaissance Imaging Spectrometer for Mars, aboard NASA's Mars Reconnaissance Orbiter, can image the planet in up to 544 wavelengths of reflected sunlight. For this image, Livonia, N.Y., students highlighted the spectra that indicate the presence of igneous minerals, which are formed by cooled magma. Reddish areas indicate olivine and blue-to- greenish areas indicate pyroxene. The students are participating in high school students NASA's Mars Exploration Science Data Teams project.
