Chang 'e IV and Yutu II were successfully awakened. What are their important tasks on the moon?

What we need to know is that Chang 'e IV is a carrier, carrying the lunar rover Yutu II. The main task of Chang 'e IV is to send Yutu II to the moon, and then let Yutu II start working. Here, I want to explain why Yutu II woke up successfully, because Yutu II was actually dormant after being sent to the moon, so why did Yutu II, as a lunar rover, sleep? In fact, this has a lot to do with the environment of the moon. You know, the weather on the moon is very different from that on the earth. It is divided into day and night.

If it is during the day, the surface temperature of the moon is likely to reach about 200 degrees below zero. At this time, the lunar rover can't work normally at all, which is likely to damage the internal structure of the lunar rover. Yutu II will sleep for a while, and wait for a suitable opportunity to wake Yutu II, so that our lunar rover can work normally on the moon.

In fact, sending a lunar rover to explore the moon is not a patent of our country. Other countries also have their own lunar rover on the moon. The main task of the lunar rover is to detect the surface of the moon, its structure, the temperature and air changes of the moon, and collect some soil samples and some other gases of the moon for our study if possible. Some people may ask, then why should we detect these data to observe the moon? What help or significance does this have for human beings on our planet? In fact, observing the structure of the moon, its air and detecting its matter are still of great help to us. There are some materials on the moon that are not available on the earth. We can make some special materials for our science and technology based on these materials, and we can also infer the landforms and some approximate data of planets similar to the moon based on observing the air quality and meteorology of the moon.

In a word, after the successful awakening of Yutu II, its mission on the moon is very important, which helps us to know more about the moon and the whole universe. These detectors can be said to be our human eyes and our human brains, which let us know more about what the world outside the earth is like.
