    Mars Odyssey arrived at Mars on 24 October 2001. The spacecraft was inserted into an 18.6 hour elliptical capture orbit. Aerobraking was initiated during ODY's 10th orbit. Aerobraking continued until 11 January, 2002, coinciding with ODY's 336th orbit. At that time the orbit was a 2-hour near polar orbit with 400 km radius. Mapping science began on January 30, 2002. The spacecraft carried the Mars Radiation Environment Experiment (MARIE), the Thermal Emission Imaging System (THEMIS), and the Gamma-Ray Spectrometer (GRS). These data are stored in the Geosciences Node node.

    Basic Mission Goals
    The primary science goals were to gather data to further clarify the life-supporting qualities of the Martian environment, to characterize the climate and geology of Mars and to study potential radiation hazards to possible future astronaut missions. Odyssey was also designed to provide a communications relay for future missions to Mars.
