Scott I have kept up with Mars atmosphere,and it is a mixture of 95%
carbon dioxide Nitrogen 2.7% Argon1,6% and.0.7% ? Its pressure is 1%
of Earth's atmospheric pressure. Water molecules are broken down to
their two elements by the Sun's unblocked radiation,and hydrogen is lost
to space. This is a fact and the reason water can't exist on Mars
surface. This is why the rovers can't find one molecule of water This
is why it might be under ground??? This is why it might be under the
frosty Co2 at the north pole??? The process the Sun's radiation for
breaking water apart is called Photsynthesis.it is why Mars has no ice
on its surface,and why my disagreeing fits. TreBert
