South Pole Neutron View |
| Original Caption Released with Image |
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. NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C. The neutron spectrometer was supplied by the Los Alamos National Laboratory,Los Alamos, N.M., and is one of the instruments in the gamma ray spectrometer instrument suite, which was supplied by the University of Arizona, Tucson. Lockheed Martin Astronautics, Denver, is the prime contractor for the project, and developed and built the orbiter. Seehttp://grs.lpl.arizona.edu [ http://grs.lpl.arizona.edu ] for more information. Odyssey mission operations are conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena. |

Global Neutron View |
| Original Caption Released with Image |
Observations by NASA's 2001 Mars Odyssey show a global view of Mars in intermediate-energy, or epithermal, neutrons. Soil enriched in hydrogen is indicated by the deep blue colors on the map, which show a low intensity of epithermal neutrons. The view shown here is a map of measurements made during the first week of mapping by NASA's 2001 Mars Odyssey spacecraft in February 2002 using the neutron spectrometer instrument. The central meridian in this projection is zero degrees longitude. NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C. The neutron spectrometer was supplied by the Los Alamos National Laboratory,Los Alamos, N.M., and is one of the instruments in the gamma ray spectrometer instrument suite, which was supplied by the University of Arizona, Tucson.

Global Map, High-Energy Neutrons |
| Original Caption Released with Image |
A high content of hydrogen in Mars' southern polar region is apparent in this global map of high-energy neutrons measured by the high-energy neutron detector on NASA's 2001 Mars Odyssey spacecraft. The neutrons were measured by the medium detector (in counts per second)during the first week of mapping, in February 2002. Space background neutrons have been subtracted. The pixels are 10 degrees by 10 degrees. NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C. The high-energy neutron detector was supplied by the Russian Aviation and Space Agency and is one of the instruments in the gamma ray spectrometer instrument suite, which was supplied by the University of Arizona, Tucson. Lockheed Martin Astronautics, Denver, is the prime contractor for the project, and developed and built the orbiter. Seehttp://grs.lpl.arizona.edu [ http://grs.lpl.arizona.edu ]for more information.

Southern Hemisphere Neutron Map |
| Original Caption Released with Image |
Observations from NASA's 2001 Mars Odyssey produced this high-energy neutron detector map of martian neutrons in the southern hemisphere. The blue region around the south pole indicates a high content of hydrogen in the upper 2 to 3 meters (7 to 10 feet) of the surface. The neutrons were measured by the medium detector (in counts per second)during the first week of mapping, in February 2002. The space background neutrons have been subtracted. The pixels are 10 by 10 degrees. NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C.
