This colorized image from the visible and infrared mapping spectrometer onboard NASA's Dawn spacecraft shows temperature variations at Tarpeia crater, near the south pole of the giant asteroid Vesta.
This map, made from data obtained by NASA's Dawn spacecraft, shows the distribution of pyroxene, an iron- and magnesium-rich mineral, in the southern hemisphere of the giant asteroid Vesta.
These images of Tarpeia crater, near the south pole of the giant asteroid Vesta, were obtained by the visible and infrared mapping spectrometer on NASA's Dawn spacecraft.
This map from NASA's Dawn mission indicates the presence of hydrated minerals on the giant asteroid Vesta about 30 degrees north latitude, in August 2011. At the time, it was winter in Vesta's northern hemisphere.
This colorized map from NASA's Dawn mission shows the distribution of minerals across the surface of the giant asteroid Vesta. It was made from spectra -- or data collected in different wavelengths of radiation.
