2001 Mars Odyssey: GRS
Instrument Suite (GRS/NS/HEND)
The GRS instrument
suite includes the Gamma Ray Spectrometer (GRS), Neutron
Spectrometer (NS), and High Energy Neutron Detector
(HEND). GRS data sets are produced by the GRS Science
Team at the University of Arizona (UA). They are
archived by the Geosciences Node.
