Spectra of Mercury were obtained at the Infrared Telescope Facility on Mauna Kea, HI using SpeX. There is no indication of any absorption feature associated with FeO in Mercury’s regolith. There is a 5μ m excess in thermal flux similar to that observed from the Kuiper Airborne Observatory (KAO) using HIFOGS. Spectra from varying locations do exhibit different slopes and flux indicating different surface temperatures at different locations.
