Mars Odyssey Epithermal Neutron Data overlayed on MGS/MOLA Topography Data (Flat, Smoothed)
|
Mars Odyssey's Gamma-ray spectrometer (GRS) instrument has detected large
amounts of Hydrogen on Mars, particularly near the south pole. This is an
indication that water ice exists in the upper meter of these areas of the
Martian surface. The epithermal neutron data ranges from 0 to about 12 counts per second.
The blue areas indicate high concentrations of Hydrogen (low epithermal neutron counts).
A series of animations was generated to support a
Space Science Update (SSU) on the topic. These animations were match-rendered
with unsmoothed, smoothed, and viking true-color data.

*Please note: the SVS does not fulfill requests for copies of the tapes in our library. On some of our animation pages, there is a direct link to a video distribution service from which tapes, handled by the Public Affairs Office (PAO)/Goddard TV, including some of our animations may be ordered. General information on this service can be found here. |
