NASA HighRise captured "Bear face" on Mars

A new image from Mars introduces a structure that looks like a "bear face".  If we zoom the image, we can see that the "Bear's nose" is the hill, and there is a "V" shaped scar. And there is a circle-shaped crack around that structure. Maybe there is some kind of gas bubble at that point. 

Carbon dioxide ice is unstable, and if the temperature in gas closure starts warming it turns to gas very soon. There is only a small temperature mirror, where liquid carbon dioxide exists. When that gas started to erupt. 

It formed the "bear's nose". Then the landscape fell. Circle-looking structure around the "bear's nose" formed when the landscape around that bubble fell. That means the Bear's face is a geological monument.

The sound of the devil's sandstorm was the first time recorded on Mars.

"Dust devils on Mars are small whirlwinds of dust that occur when the sun heats the surface of the planet, causing the air to rise and form a vortex. These dust devils can reach heights of up to several kilometers and have winds that can reach speeds of up to 60 km/h. Dust devils are common in many areas of Mars and can be found in both the northern and southern hemispheres". (ScitechDaily.com/Scientists Obtain First-Ever Sound Recording of Dust Devils on Mars)

The devil's sandstorms form in a weak gravitational field when the wind rises sand flowing over the planet's surface. The devil's sandstorms create very high-voltage electricity when small sand bites gall against each other. That thing can cause danger for probes. Another name for devil's sandstorms is the dust devil. 

There are different sizes of dust devils. Some of them are small tornadoes. Researching those things researchers can find. What is the dust devil's role in giant sandstorms that can cover almost the entire Mars planet? There is the possibility that the dust devils are acting like giant cylinders that put the atmosphere move between them. 

 Those giant sandstorms are covering almost half of planet Mars. The thing that makes those things dangerous is the friction of the dry sand. That thing forms static electricity. The duration of the sand devil determines how much static electricity it can create. If a long-term sand tornado hits the probe it can cause electric shock. But luckily the planet Mars' atmosphere is not very thick. 

But on Saturn's Titan moon, the devil's sandstorms are more dangerous. There the weak gravitation along with the thick atmosphere is making it possible that the sandstorms can exists longer. 

The devil's sandstorms are possible on Mars and Saturn's Titan where the atmosphere is thicker than on Mars. On Titan, the devil's sandstorms are more dangerous than on Mars. The reason for that is the higher gas pressure makes it possible that the speed of those sand bites can rise higher than on Mars. And those sandstorms are acting like abrasive blasts or large groups of fast-flying bullets. 

When we think about weak gravitation and life forms. We must realize one thing. The friction on the weak gravitation field is lower than in the strong gravitational field.

That means the speed of the gas is higher on those planets. And that thing causes friction where the gas can turn quite hot. There is also the possibility that devil's sandstorms are making that planet unable to host highly advanced civilizations because the sand tornados are causing so powerful electromagnetic phenomena. That electronics will jam on that planet.

Icy moons and lifeforms. 

Under the icy surface of icy moons is the ocean. But there are very high-speed flows in those oceans. 

The tidal forces are keeping those oceans in Europa and Enceladus. The planet's gravitation forms the flow of those icy moons' oceans. And that flow makes the friction and heat in oceans. 

The hypothetical lifeforms can use this temperature as an energy source. But those flows can also deny the forming of life forms. 

And if those flows in the deep oceans of the icy moons are high enough, that can destroy the complicated protein molecules that are necessary for life. Or those flows can make it impossible that cells can make chains. And those lifeforms are extremely primitive.

Was Mars alive or not in the past?

The image above) Mars that it looks today. You can see the dark Greenland-shaped area on the northern side of that planet. There is a possibility that this Greenland-shaped structure is the result of the asteroid impact. 

If that asteroid impacted the ancient Martian sea, that covered the entire northern area of that planet. That asteroid turned the water into overheated plasma. And that impact destroyed the primitive organisms that lived in that sea. 

That same or similar impact would also melt the entire mantle of that planet. And that thing could destroy all genetic material from the primitive prokaryotic bacteria that could live in that sea. 

The fact is that there was no oxygen in the young Mars' atmosphere. That means those hypothetical organisms did not exist for a long time. Maybe they had no time to release a remarkable mass of oxygen into that planet's atmosphere. The end of those organisms was meteorite impact. 

*******************************************************

But in some theories, there is a small possibility to find active bacteria on Mars. 

That those bacteria lurk under Mars's surface. The volcanic activity on Mars means that there is a possibility that deep under the core of the Red Planet could be active bacteria that can use volcanic temperature as an energy source. 

*******************************************************

Were there some bacteria on ancient Mars?

Maybe the samples that the Perseverance probe sends to Earth will solve that question. There is the possibility that Mars' atmosphere was not oxygen almost at all in the past. But there was some kind of sea. And then we must realize that in the history of Earth, the young Earth had no free oxygen in its atmosphere. The first cells and photosynthetic bacteria released oxygen into the atmosphere. 

And maybe similar things could happen on Mars. But then some kind of meteorite or comic impact destroyed that planet. There is the possibility that life on Mars was not very advanced. And in another model, those prokaryotic bacteria-level organisms didn't have time to create oxygen in the Martian atmosphere. And all that oxygen was in that ocean far away in the past.

The suspected lifeforms on Red Planet were not very highly advanced. They could be prokaryotes that lived in that ancient ocean. 

At this point, we must realize that Earth is not Mars. If some lifeforms lived on Mars. That doesn't mean they would not be higher level than some procaryotic bacteria. In some speculations, life on Mars has just begun. There is the possibility that the genomes of those extremely primitive organisms were in the form of RNA. 

And then the meteorite ended that story. Maybe that meteorite moved Mars to a new trajectory. In that theory, the lifeforms on that planet were like some kind of cyanobacteria. The end of that alien bacteria was some cosmic catastrophe. 

There is the possibility that a large asteroid impacted Mars' sea. That impact happened at interplanetary speed. 

And it just turned that ocean to plasma. And that plasma could destroy all genetic material on that planet. 

There is a possibility that even those samples that Perseverance brings on Earth would not give a straight answer to that question. Maybe, the heat of impact destroyed those hypothetical alien bacteria's  RNA and other genetic material when Mars lost its core.
