What IS TES?

TES is both an instrument and a technique. The Thermal Emission Spectrometer is a scientific instrument that first flew aboard the Mars Observer spacecraft. Following the loss of that spacecraft, TES was rebuilt and launched along with five of the original seven Mars Observer instruments aboard the new Mars Global Surveyor spacecraft. The purpose of TES is to measure the thermal infrared energy (heat) emitted from Mars. This technique, called thermal emission spectroscopy, can tell us much about the geology and atmosphere of Mars. TES data will provide the first detailed look at the composition of Mars. Follow the links to find out how this is done.
