An interesting article, written without hype, labeling unknowns as unknown, and admitting when a hypothesis is naught more than speculation. All acceptable, imo.
Yes, there is H20 on Mars, and there is actually ICE - but far more dry ice than H20 ice. *w*
It is damned cold there, and NO magnetic 'shield' as on earth. That implies that Mars does not have a liquid/molten core, as earth does. (Rotation and flows of molten material in earth's core produces our magnetosphere, and it's reversals. BIG EFFECTS on Our atmosphere, especially at the magnetic poles where the sphere 'dives' back down to earth leaving a huge gaping hole where solar and cosmic radiation more easily reach the earth's surface. The seasonal ozone hole is one result, coupled with the earth's tilt and orbit.'
Anywhooz, found the science in the article interesting.
Maybe some of ya'll might also.

Mars' atmosphere is over 100 times thinner than Earth's.
According to ESA, Mars' atmosphere is composed of 95.32% carbon dioxide, 2.7% nitrogen, 1.6% argon and 0.13% oxygen. The atmospheric pressure at the surface is 6.35 mbar which is over 100 times less Earth's. Humans therefore cannot breathe Martian air.
So much for the BS about CO2 'causing global warming' ... LOL
Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good ...
