Abstract
An accurate thermal correction applied to Moon Mineralogy Mapper (M 3 ) visible/near-infrared (VNIR) spectroscopy data is necessary for proper interpretation of lunar surface hydration (i.e., OH − /H 2 O) signatures. We compare thermal correction techniques applied to both global and targeted M 3 image data cubes to assess correction effects on M 3 3 μ m region observations, with implications for interpreting the presence of hydrated materials on the lunar surface. We present M 3 VNIR spectra collected at five different lunar highlands study sites, acquired from separately prepared images with different thermal corrections applied. The recently applied thermal correction by K. Wohlfarth et al. reveals VNIR spectral signatures consistent with the presence of hydration at all study region sites. The observed hydration signatures are different and generally weaker or absent in M 3 Level 2 global and targeted reflectance data currently available on the Planetary Data System.
