Thermal Emission Imaging System

Thermal Emission Imaging System - Payload - 2001 Mars Odyssey Spacecraft

     The thermal emission imaging system is a onboard payload installed in the Mars spacecraft known as 2001 Mars Odyssey. It was capable of imaging the infrared and visible part of the electromagnetic spectrum. It is used to determine the surface temperature and mineral distribution on the surface of Martian body.It runs on 14 watts of power.

Manufactured and Management:

     The THEMIS was manufactured by Santa Barbara Remote Sensing . The control and management of this payload was undertaken by Mars Space Flight Facility at Arizona State University.

THEMIS and TES Comparison:

     The processced image of THEMIS is very clear as compared to the Thermal Emission Spectrometer. THEMIS detects the minerals and temperatures at nine different wavelengths. Eight of these wavelength range from 6 to 13 micrometers and the ninth one is about 14.9 micrometers.


     Thermal Emission Imaging System discovered variety of rocks and minerals. Some of them are:
  1. Low-Silica Basalts
  2. High Silica Dacite
  3. Olivine
  4. Ultramafic basalts
  5. Quartz
  6. Magmas
  7. Mantle
  8. Granitoid Rocks
