What is the world of Mars, 270 million kilometers away from us, like? You may be curious, how is it different from the Earth world? Do you have green mountains and water, flowers, birds, insects and fish, and cloud and rain movements? When you see the photos sent back by Tianwen No. 1 and Zhu Rong, you will be disappointed.
Now, there are three rovers on the surface of Mars on missions, Curiosity of the United States, Perseverance of the United States and Zhu Rong of China, Curiosity driving inside the Gehry impact crater, Perseverance driving inside Jezero Crater, and Zhu Rong driving in the southern part of the Utopian Plains, each on its own mission.
Zhu Rong sent back a selfie
Recently, the Chinese Zhurong sent back a selfie after driving 1784 meters on the Martian utopian plain, and the selfie attracted the attention of the Chinese people, as before, showing a corner of the sun panel platform, but compared with the selfie taken on May 19, 2021, the difference is not generally large.
May 19, 2021 is the 5th Mars Day when the Zhurong rover landed on the Martian Utopia Plain, taking pictures has become the most important mission at this stage, Zhurong Tianwen-1 landing platform for mutual photography, Zhurong nearby terrain to take pictures, Zhurong also did not forget to take selfies on its own solar panels.
The selfie photo of the 5th Martian Day shows a black solar panel, but now the selfie shows that the solar panel is covered with a layer of yellow sand, the solar panel is not afraid of the sun and rain, the most feared is the sand, which means that the power generation efficiency of ZhuRong is gradually declining.
The current selfie also shows that there is a white satellite signal receiver behind the solar panel, shaped like a pot, and it also receives a lot of yellow dust, and the bumps of the Zhu Rong Mars rover make all this yellow dust pile up at the bottom of the satellite signal receiver.
Don't worry, right now, The power supply of ZhuRong is normal, meeting the needs of all equipment and instruments, and the satellite signal receiver is also working properly. Even if the yellow dust on Zhu Rong's body is piled up very thickly, we should not worry, mainland astronauts are not vegetarians, and have long considered these problems.
Zhu Rong solar wing and satellite signal receiver have been specially designed, the solar wing can be swung to remove a part of the sand, can also be blown away by the natural wind, blow off a part of the sand, satellite signal receiver can also be flipped to pour out the yellow sand at the bottom, but there is no need to do this at present.
Tianwen-1 sent back a batch of mars photos
At the same time, Tianwen 1, which orbits Mars, also sent back a batch of Mars photos, showing the extraordinary Martian world at a top-down angle, with a maximum resolution of 0.5 meters.
There is a black-and-white photograph that clearly shows all of Zhurong's movements over the past 10 months, showing the Tianwen-1 landing platform, parachute and heat shield, and the Zhurong rover, as well as multiple white strips and craters, which are moving sand dunes.
Two other color photos show that Mars is erupting in a terrible local dust storm, yellow sand rolling, the surface of Mars is completely covered with dust, for a solar-powered Mars rover, how terrifying it is, when opportunity was silent in a sudden sandstorm.
These pictures of Mars are thought-provoking
Although Mars has a large number of mountains, even more majestic than Mount Everest on the Himalayas, the mountains of Mars are bare, with no green vegetation, no purple flowers, no chirping sparrows, and no croaking frogs.
The Martian world is barren, with no liquid water, no life, no air, and no rainfall. Although there have been rivers and large lakes in the past, there is now only a sea of sand with no end in sight, and dust storms that often sweep half of Mars.
The photos from Zhu Rong and Tianwen 1 make people wonder: Why did humans have to colonize a planet with such a harsh environment? Oxygen, food, water, housing are all problems, do all these daily necessities have to be transported from the earth? If that's the case, even taking a breath of air is an extreme luxury.
At the same time, these Mars photos also tell us that the alien world is not as beautiful as we think, the most beautiful world is in front of our eyes - the earth, we must cherish the earth, do not let it become as desolate as Mars.
At last
The Martian world is a big disappointment, not suitable for human habitation, but this does not mean that there is no scientific exploration value, China's Zhu Rong has traveled 1784 meters on Mars, and now continues to drive south, while exploring, while taking pictures, I believe that it will send back wonderful Mars photos again, let us understand the appearance of Mars in more detail.
