South Pole Neutron View
October 7, 2009
NASA's 2001 Mars Odyssey spacecraft provided this view of the south pole of Mars in intermediate-energy, or epithermal, neutrons. Soil enriched in hydrogen is indicated by the deep blue colors on the map, where a low intensity of epithermal neutrons is found. The view shown here of the south pole of Mars comes from measurements made during the first week of Mars Odyssey's mapping, in February 2002, using the neutron spectrometer instrument.
