Preliminary results of imaging spectroscopy of the Humorum Basin region of the moonImaging spectroscopy of the lunar surface was carried out using a CCD spectrograph employed as an imaging spectrometer at the University of Hawaii 2.24-m telescope at Mauna Kea Observatory. A portion of the Humorum multiringed impact basin was observed, yielding an imaging spectroscopic dataset consisting of approximately 400,000 spectra covering the wavelength region 0.7-0.98 microns at a spectral resolution of 200 (lambda/Delta-lambda). Results of this analysis included (1) identifying craters and other explosures of highland material within the bounds of Mare Humorum, (2) identifying craters in the highlands adjacents to Mare Humorum that excavate buried mare basalt, and (3) identifying two spectral units in the highlands that likely represent compositional units. The region is shown to be extremely diverse spectrally and demonstrates the ability of imaging spectroscopy to enable a qualitative improvement in the ability to identify and map compositional units.
