2001 Landing Site Thermal Inertia

CU Thermal Inertia Web Site

OCTOBER 1999: We have put together high-resolution thermal-inertia maps of the prospective 2001 landing sites. These maps represent our most up-to-date thermal inertia data derived from MGS Thermal Emission Spectrometer observations. These maps are being provided to the scientific community prior to publication in order to aid in landing site evaluation for the 2001 mission [which evolved into the MER 2003 missions].

The ground track maps show TES thermal-inertia ground tracks in an MGS inertial reference frame. Latitude and longitude grids are overlain to provide this spatial reference.

The ground tracks with basemaps are these same maps underlain with a USGS mosaic basemap. The ground tracks have been shifted to approximately align thermal inertia with surface geology in the USGS-frame basemap image. This shift is performed by aligning a number of visible geologic features with thermal inertia features. The correlation is not perfect and the alignment may be off by many kilometers. One should rely on the latitude-longitude grid provided for interpreting landing site conditions from thermal inertia. These maps are provided to give a basic geologic context. (The Hesperia map contains no realignment due to a lack of thermal-inertia reference points to work with.)
