How Similar is Water On Mars To Water On Earth?
New evidence suggesting the existence of water flowing on Mars indicates the possibility for life to exist on the Red Planet.
NASA’s Mars Reconnaissance Orbiter have taken images and videos of dark, finger-like features running down a number of Martian slopes in the middle latitudes of the Planet’s southern hemisphere. The lines become more visible in the warm season, suggesting that they could have been created by the flow of certain volatile chemicals which boils at low temperatures.
These flows then dry up in colder seasons. The strongest candidates are water and carbon dioxide, according to a study by planetary geologists at the University of Arizona.
Atmospheric pressure on Mars (or Earth) is much too low to have liquid CO2. What are they talking about?
I’m pretty sure too that H2O is H2O, whether it is on Mars or Earth.
