Medusae Fossae-elysium Region, Mars: Depression in the Hend/odyssey Map of Mars Epithermal Neutrons


Introduction. The first data from the Gamma Ray Spectrometer (GRS) onboard Mars Odyssey spacecraft showed that the low neutron fluxes characterize both subpolar regions of Mars [1-3]. The low neutron fluxes mean the presence of hydrogen-rich soils and have been i nterpreted as an indication on abundant water ice in these areas. The equatorial region of Mars… (More)
