  30. R & D on Advanced Detectors ODYSSEY Orbiter MissionHEND: High Energy Neutron Detector. First Results:HEND has 4 signals of neutrons from sensors SD, MD, LD and SC/IN, and for each of them the map of orbital measurements is currently produced. The map of MD sensor is contributed by epithermal neutrons mainly left. This MD map is consistent with the map for epithermal neutrons from Neutron Spectrometer. Count rate over the South Pole is 5-10 times lower (blue region) – doubtless water presence. TJH: JINR 50th, 3/27/2006
