According to CCTV, in order to make the rover better cope with the environment and climate on Mars, the astronauts also set up a test ground to simulate the Martian environment on the ground.


The test site, which simulates the Martian environment, is mainly used to test the control system of the rover after it arrives on Mars. How to go, where to go and whether to go or not, we all have to pass this test field to achieve the purpose of a test.

In the process of moving, the Mars rover relies on these two big eyes. These two big eyes are navigation terrain cameras, which can see further and come from the main planning route.


There are two big eyes under it. These two big eyes are obstacle avoidance cameras. Although they don't see far away, they can see at a wider angle. It will send a command to the rover in case of emergency, and the rover will stop automatically.

In the actual driving process, the two obstacle avoidance cameras in the front and the two obstacle avoidance cameras in the back, as well as the two big eyes, will work with each other to cooperate with the Mars rover.

In the course of the rover's travel, it relies on these six wheels. These six wheels can make a positive or negative 90 degree turn, so the rover can move horizontally like a crab.


If it falls into a pit, another way for it to move is to wriggle, crawling slowly like a worm. The two front wheels will lift up and become the shape of a hand. The rear wheels will keep still and slowly climb out of the pit.

Because Mars is much farther from the sun than the earth is from the sun, the solar illumination on Mars is only about 40% of that on earth. In order to meet the energy requirements of the Mars rover working on Mars, the solar panels are particularly large.

Its solar panels are much larger than the previous Yutu and yutu-2, which are composed of four solar panels. The four solar panels are designed in the shape of a butterfly. On the one hand, it is easy to store, on the other hand, the butterfly is more beautiful, also reflects a romantic science students.


It is worth mentioning that tianwen-1 Mars rover has a high degree of self-control, and it works normally in sunny weather. When encountering dust weather, the rover enters the minimum working mode. When encountering severe dust weather, Mars rover will automatically power off and sleep to protect its instruments from bad weather damage. At the same time, it will wake up automatically when the weather gets better.

It is reported that in May 2021, the rover will land on Mars, when it will shine.
