Long ago the Red planet was very similar to the Blue: it flowed a river of liquid water, were frequent rains, and in the far North of the planet stretched a giant ocean. But suddenly something went wrong. Just a few thousand years all the water on Mars or evaporated, or went under the surface, leaving behind only rusty sand, impregnated by cosmic radiation. On the mystery of such a drastic transformation scientists are fighting for decades. What happened on Mars? And whether the planet could be similar to the Earth?
Did Mars liquid water?
Scientists have long known that the water was indeed abundant on ancient Mars. Despite this, the academic circle has never existed consensus about whether it is liquid water available at the surface of the planet, or it was largely presented in the form of ice.
Was the temperature on Mars is high enough to allow water to be in liquid state? A new comparison of the patterns of appearance of minerals on the red planet with the same minerals on Earth lends weight to the idea that early Mars could have several long periods, during which prevailing rains and heavy rains. When the warm and wet period ended, there came a kind of glacial periods, when all the water on the surface froze completely.
According to a new study, which was conducted by Professor of Geochemistry from Purdue University Briony Horgan, approximately 3 billion years ago Mars could experience peculiar and irregular temperature spikes on its surface.
Analysis of the Geology of Mars also supports this idea. Despite this, climate models show that because of the extremely small quantity of heat coming from the young Sun, liquid water couldn’t exist on the planet.
However there is a caveat.
Liquid water could be on the red planet, subject to the availability of a dense atmosphere or yet unexplored, any geological or chemical process, making the planet warmer.
The research team compared the data on the characteristics of the earth’s minerals with the properties of Martian rocks detected by CRISM spectrometer on NASA, which is currently orbiting the red planet. The spectrometer can remotely identify surface chemical where once there was water. In the experiment, it was found that Martian minerals were very similar to the minerals found on Earth. In addition, those and others were formed as a result of prolonged exposure to water, which once again confirms the theory that in the past Mars could really be a lot like modern Earth, with plenty of liquid water.
What could be rain on Mars?
If you imagine that on modern Mars, there is sufficient to ensure a cycle of the amount of liquid water, while on the red planet, we would be able to witness a very interesting phenomenon: the raindrops during heavy rains would be several times larger than the earth. A similar phenomenon we could see not only on Mars but also on other planets with low gravity.
Clouds in such areas would be formed at a considerably higherthan on the Ground that maybe would open your eyes a picture of the sort of unusual eye.
