In the Spacecraft Assembly and Encapsulation Facility 2 (SAEF-2), workers prepare to remove the High Energy Neutron Detector (HEND), part of the Gamma Ray Spectrometer (GRS), from the 2001 Mars Odyssey Orbiter. The HEND was built by Russia’s Space Research Institute (IKI). The GRS will achieve global mapping of the elemental composition of the surface and determine the abundance of hydrogen in the shallow subsurface. The orbiter will carry two other science instruments THEMIS and the Mars Radiation Environment Experiment (MARIE). THEMIS will map the mineralogy and morphology of the Martian sur

The GRS will achieve global mapping of the elemental composition of the surface and determine the abundance of hydrogen in the shallow subsurface. The orbiter will carry two other science instruments THEMIS and the Mars Radiation Environment Experiment (MARIE). THEMIS will map the mineralogy and morphology of the Martian surface using a high-resolution camera and a thermal infrared imaging spectrometer. 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 April 7, 2001, aboard a Delta 7925 rocket from Launch Pad 17-A, Cape Canaveral Air Force Station
