TES, The Thermal Emission Spectrometer at Arizona State University (ASU), is one of five instruments carried on the Mars Global Surveyor spacecraft (MGS).
MGS was launched in November 1996 and made the last transmission to Earth in November 2006.
Their website presents data from the TES instrument at Mars, as well as an introduction to infrared spectroscopy and access to the Spectral Library at Arizona State University.
You will also find links to many other Mars-related websites, including their very active ASU-Mars K-12 outreach program.
