Water found in Mars north polar regions
============================================================
Posted: Sat, Oct 12 7:20 AM ET (1120 GMT)
Planetary scientists have confirmed that the north polar
regions of Mars have similar deposits of water ice as
previously seen in the south. Scientists announced at a
planetary science conference this week that the neutron
spectrometer on the Mars Odyssey spacecraft has picked up
similar concentrations of hydrogen in the north as was seen
in the south early this year. The hydrogen concentrations
are high enough that scientists believe that it could only
exist in the form of water ice within a couple meters of the
surface. While Mars Odyssey has been in orbit around Mars
for nearly a year now, observations of the north polar
regions was prevented by the presence of a large seasonal
dry ice cap during the northern winter.
