In the Spacecraft Assembly and Encapsulation Facility 2 (SAEF 2), workers check the Thermal Emission Imaging System (THEMIS) before attaching to the 2001 Mars Odyssey Orbiter (background). THEMIS will map the mineralogy and morphology of the Martian surface using a high-resolution camera and a thermal infrared imaging spectrometer. The orbiter will carry three science instruments THEMIS, the Gamma Ray Spectrometer (GRS), and the Mars Radiation Environment Experiment (MARIE). The GRS will achieve global mapping of the elemental composition of the surface and determine the abundance of hydrogen
In the Spacecraft Assembly and Encapsulation Facility 2 (SAEF 2), workers check the Thermal Emission Imaging System (THEMIS) before attaching to the 2001 Mars Odyssey Orbiter (background). THEMIS will map the mineralogy and morphology of the Martian surface using a high-resolution camera and a thermal infrared imaging spectrometer. The orbiter will carry three science instruments THEMIS, the Gamma Ray Spectrometer (GRS), and the Mars Radiation Environment Experiment (MARIE). The GRS will achieve global mapping of the elemental composition of the surface and determine the abundance of hydrogen in the shallow subsurface. The MARIE will characterize aspects of the near-space radiation environment with regards to the radiation-related risk to human explorers. The Mars Odyssey Orbiter is scheduled for launch on April 7, 2001, aboard a Delta 7925 rocket from Launch Pad 17-A, Cape Canaveral Air Force Station
