2001 Mars Odyssey - Scientific Instruments

Scientific Instruments

The three primary instruments Odyssey uses are the:

  • Thermal Emission Imaging System (THEMIS).
  • Gamma Ray Spectrometer (GRS), includes the High Energy Neutron Detector (HEND), provided by Russia.
  • Mars Radiation Environment Experiment (MARIE).

On May 28, 2002 (sol 210), NASA reported that Odyssey's GRS had detected large amounts of hydrogen, a sign that there must be ice lying within a meter of the planet's surface. GRS is a collaboration between University of Arizona's Lunar and Planetary Lab., the Los Alamos National Laboratory, and Russia's Space Research Institute.

Famous quotes containing the words scientific and/or instruments:

    “What happened at Hiroshima was not only that a scientific breakthrough ... had occurred and that a great part of the population of a city had been burned to death, but that the problem of the relation of the triumphs of modern science to the human purposes of man had been explicitly defined.”
    —Archibald MacLeish (1892–1982)

    “Sound all the lofty instruments of war,
    And by that music let us all embrace,
    For, heaven to earth, some of us never shall
    A second time do such a courtesy.”
    —William Shakespeare (1564–1616)
