Within the first few days of the 2001 Mars Odyssey spacecraft's science mapping mission, project scientists have detected the likely presence of significant quantities of water ice in the red planet's southern hemisphere. The presence of the ice is indicated by high quantities of hydrogen detected by Odyssey's GRS (Gamma Ray Spectrometer) instrument, which was designed to search for 20 different chemical elements on the Martian surface.
