2001 Mars Odyssey
Home Participate


2001 Mars Odyssey has contributed numerous science results. It has mapped the amount and distribution of chemical elements and minerals that make up the martian surface. Maps of hydrogen distribution led scientists to discover vast amounts of water ice in the polar regions burried just beneath the surface. Odyssey has also recorded the radiation environment in low Mars orbit to determine the radiation-related risk to any future human explorers who may one day go to Mars.

Mission Contribution to Mars Exploration Program Science Goals The Mars Odyssey orbiter is part of a series of expeditions to the red planet that help meet the four main science goals of the Mars Exploration Program:

Goal 1 image

Goal 2 image

Goal 3 image

Goal 4 image
Determine whether life ever arose on Mars

Characterize the climate of Mars
Characterize the geology of Mars
Prepare for human exploration


Discoveries are enabled by Odyssey’s science instruments:

Thermal Emission Imaging System (THEMIS)

Gamma Ray Spectrometer (GRS)

Mars Radiation Environment Experiment (MARIE)

Mission Objectives 2001 Mars Odyssey intends to meet these goals by accomplishing five specific objectives.
