Professor Glotch’s research interests are currently focused on two broad subjects: (1) understanding the role of water in shaping the surface of Mars in terms of both mineralogy and geomorphology, and (2) comparing laboratory spectroscopic and remotely acquired spectroscopic data and the application of these methods for solving various problems in Earth, planetary, and space science.

Remote Sensing of Martian Mineralogy  
Professor Glotch uses several remote sensing instruments to determine the mineralogy of the Martian surface. The composition of a planet’s surface is an important indicator of past geological processes including primary formation of the crust and subsequent aqueous weathering. Below is a map of the mineral hematite (a-Fe2O3) in a region of Mars called Aram Chaos. Hematite is an important mineral because it often forms in the presence of liquid water. The map was created using data from the Mars Global Surveyor Thermal Emission Spectrometer (MGS-TES) and the Mars Odyssey Thermal Emission Imaging System (THEMIS). The large crater is about 300 km across and may have once been a lake.

Remote Sensing of Martian Mineralogy


Fundamental Mineral Spectroscopy  
Professor Glotch is currently working on a project to determine the fundamental optical properties (the real and imaginary indices of refraction) of rock-forming and weathering product minerals at infrared wavelengths. These data are used as inputs into radiative transfer models to investigate the composition and scattering properties of the Martian atmospheric and surface dust. This work will contribute to studies of Martian and terrestrial atmospheric processes, mineralogy of other planetary bodies, cosmic dust, and protoplanetary disks, and the basic physics of small particulate scattering processes.
