Distance is 80 meters! Yutu 2 found a mysterious object, like a small house, which took three months to arrive.

Yutu II made another great discovery on the moon, which is a bit unusual this time! Judging from the photos taken, an object that looks like a "hut" appeared on the skyline about 80 meters away from the patrol, and it took the shape of a cube, which was more regular than ordinary rocks, and there seemed to be a "door" in the middle of the "hut".

Once the photos were released, they immediately aroused great interest. What is this? Could it be an artificial object? Is it really the "site" of Guanghan Palace?

According to the ancient legend in China, there is a Guanghan Palace on the moon, where Chang 'e, Jade Rabbit and WU GANG who cut laurel trees live. However, later people invented the astronomical telescope and made a detailed observation of the moon. People found that the moon is not a beautiful place, but a desolate place. There is no air here, but there are deserts made of moon soil and moon rocks everywhere, and there is no breath of life. 1969, the United States carried out the Apollo program, and man landed on the moon for the first time, which also confirmed that it was a barren land.

So it is surprising to find such a regular cubic object on this desolate planet. Let's analyze what this small house-like object is. The easiest answer to think of should be the mountain peak. Is this the correct explanation?

Yutu -2 and Chang 'e -4 landed together in the Von Kamen crater on the back of the moon. This crater is the oldest crater in the solar system at present, with an age of 3.6 billion years and a bottom diameter of 140 km. Except for the central peak and a few secondary craters, the terrain inside is relatively flat, which is the main landing area of Chang 'e IV.

In order to ensure a smooth soft landing, there are few obstacles in the landing area. So there should be no particularly abrupt peaks in this area. Since it is unlikely to be a mountain peak, could it be a rock in the distance? Generally speaking, ordinary rocks naturally formed on the moon are of course irregular and have ever-changing shapes.

Yutu No.2 had previously been imaged as a stone shaped like a pyramid. Although the shape of this stone is relatively regular, it can be seen at a glance that it is naturally formed, but if you carefully observe the cabin-like object in front, you will find that it is too "regular". Especially like a cube, the top is very flat and the lines on both sides are almost upright. If it is not on the moon, if it is man-made, someone will really believe it.

There is a dark area in the middle of this object, especially like a "door". The "doorposts" on both sides of the door are relatively symmetrical and complete, and it feels a bit like a "stargate", which is very different from ordinary stones you usually see. It's hard to stir up a thousand waves with one stone. Then there is another possibility: could this thing be a spaceship launched by other countries before? For example, the "hard landing" in India before.

But this possibility can easily be ruled out. Because of the soft landing on the back of the moon, China is the only one, and there is no second one in the world. In the Von Kamen Crater, a place that no other spacecraft has ever reached, there can be no other things made by human beings, so this possibility can also be ruled out. So is there another possibility: the camera on Yutu 2 is out of order, and the object in the photo is not real, just an illusion?

It's hard to make sense. Yutu II is equipped with six cameras, including two holographic cameras on the mast, two navigation cameras on the front panel and two obstacle avoidance cameras. This photo should have been taken by a navigation camera or panorama camera. The masterpieces of these cameras have been shown before, and their performance and state are good without any faults. The mysterious "house" is small, but it is more than one pixel, so it can't be noise.

In other areas of the photo, the scene on the surface of the moon and the shape of the skyline are natural. If the imaging problem happens in this area of the skyline, it is too coincidental, so it doesn't make sense. Since so many hypotheses are impossible, will this mysterious object be an alien spacecraft as many sci-fi fans expect? This brain hole is a bit big, and the possibility is even more slim. As for the statement of "Guanghan Palace", it is only a beautiful imagination, and of course it is even more impossible.

What the hell is that? The only way to answer this question is to look ahead. All the truth will come out. After all, 80 meters is still a little far. The camera on Yutu II is not a telescope, so it is not very real. Some netizens can't wait for Yutu to drive there now to find out, but it's urgent. It is estimated that it will take two to three months, that is, about three months.

Speaking of this, some netizens were unconvinced: when Apollo landed on the moon, Americans carried the fastest speed of the lunar rover 17 km, and walked 80 meters in a short time. Why did Yutu wait for 3 months? But the actual situation is that Yutu-2 has been working on the back of the moon for 36 months, 1000 days, but the total driving distance should be between 700 and 800 meters, with an average of less than 1 meter a day. The straight-line distance is shorter and slower than that of snails. Why?

This is because Yutu II is an unmanned lunar rover working on the back of the moon. Although it is also equipped with nuclear batteries, it mainly relies on solar energy for power supply, and the power generated by battery panels is also supplied to other instruments, so the power of the power system is not large, and the design speed is not high, only 200 meters per hour, which is already very slow. But even at a speed of 200 meters per hour, the distance of 80 meters will take less than half an hour. Why wait three months?

That's because the primary task of Yutu -2 is scientific research, not racing. At each step, it needs to use its own instruments to conduct a detailed survey of the lunar surface, including infrared imaging, lunar radar, solar wind detection, and also needs to use a robotic arm to analyze the composition of the lunar surface material. The task is quite heavy, and I won't change my original plan for a suddenly discovered object.

In addition, Yutu -2 is small in size. Although it is located in a relatively flat terrain, there are still many terrain obstacles to be overcome on the road ahead, such as stones and impact pits, which often require detours. Because it is an unmanned lunar rover, you should be careful at every step. Once trapped in the pit, it is difficult to climb out on your own. Moreover, it can only move in the moonlit night, and it will sleep in the moonlit night, which greatly increases the time to reach the target.

The lunar rover on the Apollo spacecraft in the United States is a disposable vehicle, which can be thrown away in a short time. Because there are astronauts driving, even if the lunar rover is stuck in the car, the astronauts can drag it out with one hand, so it is naturally unnecessary to be so cautious when driving.

Therefore, if you want to know what the mysterious "hut" is, you have to wait for Yutu II to move over little by little. Three months is also a conservative estimate, and the actual time may be longer. Wait patiently!
