Oh, that Mars! How many interesting things have been said about him. We watched many films about Martians, we heard stories about how they were going to conquer him, they even sang him in songs. Indeed, there is no such planet whose name could become a household name as much as it happened with Mars. Mankind is very actively exploring this planet and is considering the possibility of its settlement almost in the very near future. You just need to figure out how to make the surface terraform and change the atmosphere. The entire study so far leads only to data collection and various discoveries, among which are an explanation of the processes taking place. During these studies, scientists get beautiful photographs with unusual phenomena, most of which they can already explain. Believe me, these photos have something to look at!

Does Mars Look Like Earth
We are used to the fact that Mars has already become for ussome kind of family. It even seems to us that it looks like the Earth. In some ways this is true, but there are many differences. For example, it is much smaller and more rocky. Its atmosphere is 96 percent carbon dioxide, which appears as a result of seismic activity. The pressure at the surface of Mars is about 170 times lower than at the surface of the Earth, or equal to Earth, but at an altitude of about 35 kilometers.
Farther away from us, what does ourWe have long been accustomed to the planet. For example, sunset or solar eclipse. At this point, it becomes most clear that Mars is very different from Earth.
Is there water on Mars
About liquid water definitely answerit’s impossible, and scientists either find it somewhere below the surface, sometimes they say "but, not ... we were mistaken." But there is definitely ice on the surface, however, its exact composition is not completely known.
It is located in the Korolev crater, not far from the northern polar ice cap of Mars. The crater is 81.4 kilometers wide and is filled with water ice all year round.
When local air moves over the crater, itit cools and falls down, as a result of which a layer of cold air is directly above the ice inside the crater. Gases do not differ in good heat conductivity at all and this cold layer perfectly covers the ice mass from warmer streams that pass higher. So ice is reliably protected from melting by the edge of the crater.
Where can people live on Mars?
The ice layer has a thickness of 1.8 kilometers anddiameter up to 60 kilometers, and its volume is about 2200 cubic kilometers. This is a little compared with, say, Antarctica, but it is much more than can be expected from such an arid planet as Mars.
Solar eclipse not Mars
The inhabitants of our planet are very lucky. The ratio of the distances and sizes of the Earth, the Moon and the Sun is such that our satellite and our star in the sky look approximately the same. As a result, when the moon passes between the Earth and the Sun, it closes it very beautifully, leaving only a bright crown in a circle. If it were less, we would not get such an effect. Actually, this is what is happening on Mars.
Once upon a time, when lava often flowed alongMartian surface, the landscape was covered with sand dunes. Lava flowed around these dunes and took such a form. Over time, the sand was blown away, but the lava remained in its frozen state.

Meteorite fall on mars
If you compare with our planet, then Mars cancall it a real crater exhibition. They were formed due to the insufficient density of the atmosphere of the Red Planet, which almost does not protect the surface from such an effect. The crater in the photo formed somewhere from September 2016 to February 2019.
During a strike on the surface of the planeta hole with a diameter of about 15-16 meters was formed. For such an impact, the meteorite should have a size of about 1.5 meters. On our planet, you should not even think about this, since such a meteorite will burn without a trace in the Earth’s atmosphere long before reaching its surface.
Sunset on mars
In photographs, we often see that the sky on Mars looks brown. This is true, but as soon as the sun begins to hide behind the horizon, everything changes immediately and the sky turns blue.
This phenomenon is associated with particles in the atmosphere. On Earth, smaller particles of gas in the atmosphere scatter blue light well. In the afternoon, this makes the sky seem blue to us. When the Sun sets, the rays must travel a greater distance through the atmosphere due to the fact that the rays do not reach our eyes at the shortest distance. Because of this, the blue spectrum is screened out quite strongly and mostly red comes to us. Therefore, the sky seems orange to us.
On Mara, on the contrary, there are a lot of small particles in the “air” that scatter red light very well, but at sunset they weed out it even more and mostly blue light reaches the surface.

How the surface of Mars is changing
If you look at the famous canyons of Mars, it becomes clear that everything is not so simple with this planet and it is not so monophonic as it seems. Such details look fantastic.
Weathered canyons on the surface of Redthe planets are approximately 250 kilometers long and are constantly changing, but they are doing it so slowly that we don’t have enough life to see any serious changes.
The canyons give an idea of how the surface of Mars was formed, and of which rock layers formed at different stages. This is literally a photograph of a past planet.
Teardrop-shaped formations on Mars
It once rained on Mars. As some scholars say, this used to be commonplace. Now they are not, but there are drops. Giant drops found in the crater of Copernicus.
In fact, of course to real drops theyhave little relationship. These are simply droplet-shaped dunes, which consist of a mineral called olivine, as well as magnesium silicate and iron. These substances can be found in igneous rocks and the mantle of the Earth.
However, there is not much olivine on the Earth’s surface, because it quickly erodes. This happens especially quickly when, under the influence of moisture, it turns into clay.
Due to the fact that the surface of Mars is very dry, olivine dunes can stay on the surface for a very long time and hardly change.

Of course, there are other interesting things on Mars,which can always be discussed in our Telegram chat. That is why the planet attracts millions of researchers, but so far it is not so accessible to us. In the immediate plans of mankind to make research colonies on Mars. And then we can talk about knowing him a little better. So far there are more questions than answers, but today you learned a little more.
