Tian Wen-1 sent back an image of Mars. What does Mars look like?

Although there are eight planets in the solar system, the situation of each planet is very different. For example, the temperatures of Mercury and Venus are very high, while the temperatures of gas planets such as Jupiter and Saturn are very low. In contrast, the Earth and Mars are in the livable zone of the solar system, so the temperature is relatively mild. Because there are many similarities between Mars and Earth, before we explored Mars, humans even thought that Mars might have an ecosystem similar to Earth. However, as the probe sent photos of Mars back to Earth, we saw the desolate appearance of Mars, and the dream of finding an alien civilization on Mars was shattered.

Although Mars is extremely desolate, it does not affect our enthusiasm for exploring Mars. Because the current research shows that Mars is still a terrestrial planet with water, if we humans land on Mars in the future and immigrate to Mars, developing these water and ice substances on the surface of Mars can meet the needs of our immigration to Mars. Before, we saw many photos of Mars. Previous photos of Mars mainly came from NASA, ESA and other space agencies, but the next situation is about to change. Because our Mars probe is about to reach Mars.

I believe that aerospace enthusiasts and astronomy enthusiasts have been paying attention to the latest situation of Tian Wen-1. Since the launch of Tian Wen 1 on July 23, 2020, it has been flying in space for more than six months, and it is getting closer and closer to Mars. Now the distance between Tianwen-1 probe and the earth has reached 65.438+0.84 million kilometers, and the flight mileage has reached 465 million kilometers, while the distance from Mars is only 65.438+0.65438+0 million kilometers.

According to the news report on February 5, 2002/kloc-0, Tian Wen-1 took the first photo of Mars when it was about 2.2 million kilometers away from Mars. This is the first time that our national probe has taken photos of Mars. I believe everyone has been looking forward to seeing the photos of Mars sent back by Tian Wen-1 probe as soon as possible. Now it has finally sent back photos of Mars.

In the first photo of Mars taken by Tianwen 1, we can see the surface of Mars, including Daglia Plain, Chersi Plain, Meridian Plateau, XiaParelli Pit and the longest canyon in assisi? Symbolic landforms, such as Mariner's Valley, are clearly visible. Because Tian Wen 1 has not yet entered the orbit around Mars, it is still far away from Mars when taking pictures, so we can't see too many details on the surface of Mars for the time being. However, Tian Wen 1 has now sent back the first photo of Mars, which also indicates that Tian Wen 1 will soon reach the destination of Mars.

This is not the first time that Tian Wen 1 has sent back photos of the depths of the universe. Shortly after its launch, Tianwen-1 probe looked back at the home of the earth in the depth of the universe about 654.38+0.2 million kilometers away from the earth, and used its optical navigation sensor to image the earth and the moon and take photos of the earth and the moon.

At that time, the Tianwen-1 probe was far away from the earth, so we couldn't see too many details of the earth and the moon in the photos taken back. These photos appeared in front of us, just like what we saw in the night sky? Crescent moon? . This is because the earth and the moon reflect sunlight. At that time, the side of the earth and the moon facing away from the sun was bright, and the side facing away from the sun was dark.

Tian Wen 1 is expected to arrive on Mars on New Year's Eve. In other words, Tian Wen-1 probe has entered the countdown to Mars, with only a few days left. On the same day, the Chang 'e-1 probe will fly around Mars for a period of time, and then in May this year, it will choose the opportunity to implement a soft landing, send the rover to the surface of Mars, and complete the three steps of orbiting Mars, landing on Mars and patrolling Mars at one time. When our rover is driving on the surface of Mars, we will also see the details of the surface of Mars photographed by the rover at close range, which is very worth looking forward to.
