help Mars Odyssey FAQ
How did Mars Odyssey find evidence of buried water ice?
Its Gamma Ray Spectrometer suite mapped hydrogen in the Martian near-surface. Large hydrogen concentrations, especially at high latitudes, were interpreted as water ice mixed into or buried beneath the soil.
What is the THEMIS instrument on Mars Odyssey used for?
THEMIS images Mars in visible and thermal-infrared wavelengths. Researchers use its temperature and mineral data to study landforms, surface composition, and candidate landing sites.
Does Mars Odyssey communicate with surface rovers?
Yes, Odyssey has served as a communications relay for NASA landers and rovers as well as conducting its own science. It relayed data during missions including Spirit, Opportunity, Phoenix, and Curiosity.
What longevity record does Mars Odyssey hold?
The orbiter entered Mars orbit in October 2001 and became the longest continually active mission orbiting a planet other than Earth. Its operating life has exceeded those of earlier Mars orbiters by many years.
