On the afternoon of June 26th, the opening of the Chang'e-6 returner of the lunar exploration project was held, and let's take a look at what surprises the "Space Express Unpacked" brought us!

Previously, Chang'e-6 carried out two ways of collecting in the Aitken Basin at the south pole of the far side of the moon, the first is drilling, that is, drilling through drill bits, mainly to collect samples from the interior of the moon, and the second is surface adoption, which is to collect samples directly on the surface of the moon, so we can see that two different samples were taken out when unpacking.
There is also a cold knowledge, that is, the exploration of the far side of the moon is the first exploration carried out by human beings, and the previous Apollo moon landing program was also carried out on the front side of the moon, because of the tidal lock, so the back side of the moon has always been facing away from the earth, here to explain why, because the rotation period of the earth and the rotation period of the moon are the same, so the back of the moon will always be facing away from the earth, so the moon we see has always been the front of the moon, which is why the moon is always like that.
Some people will ask, will it be difficult to explore the far side of the moon? Of course, it is difficult, because we need to control the explorer by transmitting signals to control the explorer, but the signal on the far side of the moon will be shielded by the moon, so that the explorer cannot be operated, in order to make the explorer work on the back side of the moon, we must first launch a small satellite away from the moon, so that the signal transmitted from the surface of the earth can be reflected to the explorer on the far side of the moon through this small satellite.
The Chang'e-6 mission is quite powerful, and it is also the first time that humans have explored the far side of the moon, which is more valuable for research than the lunar samples brought back by Apollo before.
