Were the rains on Mars similar to Earth?

Once upon a time, the Red Planet was very similar toBlue: rivers of liquid water flowed on it, frequent rains, and in the very north of the planet a gigantic ocean stretched. But suddenly something went wrong. In just a few thousand years, all the water on Mars either evaporated or went under the surface, leaving behind only rusty sand saturated with cosmic radiation. Scientists have been fighting over the mystery of such a cardinal transformation for more than a dozen years. What happened on Mars? And could the planet really be like Earth?

Was there liquid water on Mars?

Scientists have long known that water really was inabundance on ancient Mars. Despite this, in the scientific community there was never a consensus about whether it was liquid water that was distributed on the surface of the planet, or whether it was largely represented in the form of ice.

Was the temperature on Mars high enoughto allow water to be in a liquid state? A new comparison of the regularities of the appearance of minerals on the Red Planet with similar minerals on Earth gives weight to the idea that the early Mars could have several long periods during which heavy rains and heavy rains prevailed. When the warm and rainy period ended, there were peculiar ice ages when all the water on the surface completely froze.

According to a new study that wasconducted by professor of geochemistry from Purdue Brioni Horgan University, about 3 billion years ago, Mars could experience peculiar and uneven temperature jumps on its surface.

Mars geology analysis also supports similaran idea. Despite this, climate models show that because of the extremely small amount of heat coming from the young Sun, liquid water simply could not exist on the planet.

However, there is one caveat.

Liquid water could well be on Krasnayaplanet, subject to the presence of a dense atmosphere or as yet unexplored any geological or chemical process that made the planet noticeably warmer.

Perhaps this is what ancient Mars looked like

The research team compared data oncharacteristics of terrestrial minerals with the properties of Martian stones, discovered using a NASA CRISM spectrometer, which is currently in orbit on the Red Planet. The spectrometer can remotely identify surface chemicals where water once existed. As a result of the experiment, it turned out that the Martian minerals found were very similar to the minerals found on Earth. In addition, both of them were formed as a result of prolonged exposure to water, which once again confirms the theory that in the past Mars could really be very similar to modern Earth, having a large amount of liquid water.

What could it be like rain on Mars?

Despite the fact that there is currently no liquid water on Mars, frost and even snow can fall on the planet’s surface.

If you imagine that on modern Marsif there is enough liquid water to ensure the cycle, then, being on the Red Planet, we would be able to witness a very interesting phenomenon: raindrops during rainstorms would be several times larger than the earth. We could see a similar phenomenon not only on Mars, but also on other planets with low gravity.

Clouds in such places would form at a much higher altitude than on Earth, which, perhaps, would make the picture that opens to your eye in some way unusual for the eye.

Well, perhaps, this is what humanity is striving for - to see what has not been seen and to find that which has not yet been discovered.
