Hubble Reveals Potential Titanium Oxide Deposits at Aristarchus and Schroter's Valley Rille
This view of the lunar impact crater Aristarchus and adjacent features (Herodotus crater, Schroter's Valley rille) illustrates the ultraviolet and visible wavelength characteristics of this geologically diverse region of the Moon. The two inset images illustrate one preliminary approach for isolating differences due to such effects as composition, soil maturity, mixing, and impact ejecta emplacement. The colour composite in the lower right focuses on the 26-mile-diameter (42-kilometer-diameter) Aristarchus impact crater, and employs ultraviolet- to visible-color-ratio information to accentuate differences that are potentially diagnostic of ilmenite- (i.e, titanium oxide) bearing materials as well as pyroclastic glasses.
