TES Science Results

This page is a summary of TES science results. The most recent information about the TES instrument and the MGS spacecraft can be found on The Latest From TES! page. For a complete history of TES, read our TES News newsletters-- they date from August 1992 to January 1998.


  • The Top 25 TES Science Results!
  • A series of 13 TES results and lab spectroscopy research papers has been published in the April 25, 2000 issue of the Journal of Geophysical Research -- Planets. These papers cover topics as diverse as atmospheric temperatures, dynamics, and dust opacity, as well as surface compositions, thermal inertia, and south polar science. The references for these papers, as well as others relating to thermal emission spectroscopy and Mars geology can be found on the TES References page.
  • One of the TES instrument capabilities is that of measuring the broadband (0.3 - ~3.0 microns) visible and near-infrared reflectance, or albedo, of Mars. These measurements are given color values and plotted on rotating globes in these new animations.
  • New maps of basaltic and andesitic components on the Martian surface have been published by TES team members in the March 3, 2000 issue of the journal Science.

  • The journal Science published a series of papers detailing the early science results of the MGS instruments in the March 13, 1998 issue.
  • On December 9, 1997, TES Principal Investigator Dr. Phil Christensen presented recent science results at the American Geophysical Union Fall Meeting in San Francisco, CA.
  • At a press conference on November 10, 1997, TES data showing spectral evidence of water ice clouds and the shrinking of the south polar cap were presented. A profile of atmospheric temperatures over the Mars Pathfinder site and adjacent areas was also shown.
  • TES spectra display variations with surface temperature.
  • Images of surface temperature.
  • A color image of the surface temperatures at the south pole were the first TES data of Mars.
