Abstract

Updated radiometric calibration and systematic processing procedures for Galileo solid-state imaging data from the first (1990) Earth-Moon encounter are presented. These procedures were applied to a whole-disk imaging sequence of the Moon centered near Mare Orientale, Called Lunmap 14 (L14). Recalibrated spectra indicate that mare ponds of the limb show moderately deep 1-μm absorptions, and thus mafic mineral contents, comparable to those of other nearside basalts. Mafic mineral contents of Schiller-Schickard cryptomaria are higher than previously thought and are similar to some low-Ti nearside basalts. Many of the recalibrated spectra from South Pole/Aitken are similar to those of Schiller-Schickard cryptomaria, suggesting that many of these soils represent a mixed mare/highland lithology. -from Authors
