The northern hemisphere of Mars has entered its autumn season with a spectacular display of high-resolution images sent back by the Sky Man 1 mission

The probe took a high-resolution image of the zhurong patrol area, showing the vehicle’s track.”Ravaged by date” is China’s first successful landing on Mars rover, and start making all tasks, as of March 24, 2022, 306 “ravaged by date” have been working for Mars, for 1784 meters, returned during many precious Mars films and Mars, Mars in China study provides a large amount of data to support and help.The “Zhurong” rover has been wandering around Mars alone. Although it is “lonely”, it enjoys it. From time to time, it sends back some “selfies” of itself.Dust covering the surface of the Zhurong will also have an impact on the body, with its power generation efficiency being the most affected. However, the zhurong is in good condition and its power generation efficiency is normal.Moreover, scientists have taken into account the dusty conditions on Mars when designing zhurong, so they have taken various effective measures to prevent the efficiency of power generation from declining.The environment on Mars is very different from that on Earth, and Mars doesn’t have many of the things that happen on Earth, but dust storms are an exception.There are also frequent dust storms on Mars, and after each one, it’s a test for rovers.The Mars rover Opportunity, for example, lost contact because it was in the middle of a dust storm.It’s autumn in the northern hemisphere of Mars, when dust storms are common.On January 22, 2022, a spectacular image was captured of a localized dust storm on Mars, obscuring the surface with a thick layer of yellow sand.The two important conditions for the formation of sandstorms are wind and sand.Dust storms are normal on Earth, where there is both wind and dust. But how does the thin atmosphere of Mars, with its extremely low density, one hundredth of earth’s, create a terrible dust storm?The mechanism of earth’s wind is relatively simple.As the air rises, a low pressure is formed in the region where the air is sinking. The air moves from high pressure to low pressure in the region where the air is sinking. Wind forms.Although the Martian air is very dense, it lacks an atmosphere to hold on to the sun’s heat.As a result, half of the planet illuminated by the sun is very hot, while the other half of the planet facing away from the sun is very cold. The huge temperature difference causes the atmosphere on Mars to move very violently. Plus, Mars has only sand dunes, and no trees or tall buildings, so even though the air is thin, it can blow very strong winds.Not to mention dust, which is what Mars has in abundance.On top of that, The gravity on Mars is half that on Earth, which means that with the same wind, the dust has much less work to overcome gravity than on Earth, so it only takes a little breeze to lift the dust, which is why we often see dust weather on Mars.In the absence of trees and buildings, dust storms can be several notches more powerful, sometimes reaching heights of more than 20 kilometers, a level that is not seen from earth at all.Dust storms on Mars are not unusual, but the difficulty is that dust storms are a major challenge for Mars research.A small rover caught in a dust storm could be blown up and smashed to pieces within seconds.Frequent dust storms can also affect rovers’ components. Even a speck of dust can cause damage to delicate instruments like rovers, which can mean years of work lost.So in building the rover, scientists have taken all possible conditions into account to maximize the rover’s life.NASA released new images of Mars
