Mercury: First Spectra from 8 to 25 Microns Using MIRSISpectral measurements from 8 to 25 microns of Mercury's surface were taken using MIRSI (Mid-InfraRed Spectrometer and Imager) mounted on the NASA Infrared Telescope Facility (IRTF) on Mauna Kea, Hawaii [1]. Few spectral observations of Mercury have been made between 8 and 14 m and these are the first to be made between 17 and 25 m. The goal for these observations is to measure the emission from Mercury in the Restrahllen Bands in the 8 to 25 micron region in an effort to identify spectral features that may give clues to Mercury s composition. These observations will be compared to previous observations [2] [3] [4], and future observations made with instrumentation on Messenger at other spectral regions [5]. Spectra from the Moon were also obtained with the same instrumentation and telescope during the same observing periods.
