After Chang'e-6 entered the orbit around the moon, except for the release of Pakistan's CubeSat and a set of photos, why was there no news?
Indeed, this has surprised many people, what is this doing?
In fact, Chang'e-6 is waiting for an "opportunity", which is also the key to the mainland's implementation of the Chang'e-6 sampling mission.
Chang'e-6 arrives on the moon in 5 days! Flying around the moon all the time
That's right, after the mainland launched Chang'e-6, it took a short time to enter the orbit around the moon - that is, to reach the moon, only 5 days, which actually shows that the time period for sample return and entry into the atmosphere is only about 5 days.
The total mission will be carried out for 53 days, in fact, it will be in the orbit around the moon and sampling and other regional activities, which is also the most critical mission stage of the mainland to carry out Chang'e-6.
Including the international payloads I mentioned, four of the national payloads, at least three of which are not much progress, and of course, it is possible that some small tasks are being carried out, but it is not specified.
Let me briefly explain the four international payloads, which are the four international payloads that the Chang'e-6 was finally carried by the mainland through the solicitation and selection of two batches of international payload carrying project proposals.
These include the French radon gas detector to carry out in-situ measurement of radon isotopes on the lunar surface, the ESA lunar surface anion analyzer to detect negative ions on the lunar surface and study the interaction between plasma and the lunar surface, the Pakistani CubeSat to carry out in-orbit imaging missions, and the Italian laser angle mirror, as an absolute control point for positioning on the far side of the moon, which can carry out joint ranging and positioning research with other lunar exploration missions.
So, judging by the known and definite mission, it is the results of the Pakistani CubeSat, which has been partially successful, photos have been taken, and there will be subsequent tests such as lunar experiment technology, which has not yet been clearly stated.
Therefore, there is indeed not much news about Chang'e-6, and everyone is looking forward to all the mission nodes being executed as soon as possible, but no news is good news.
Because in the entire 20-day or so orbit around the moon, the continent still has a lot of tasks to do, and it is still waiting for an "opportunity" to think about landing on the surface of the moon.
Chang'e-6 is going to land on the far side of the moon, what time is it waiting for?
As we all know, sampling on the far side of the moon is completely different from the front side, and the Chang'e-6 landing area chosen by the mainland is also located in the south pole of the far side of the moon - the Aitken Basin, this area is also challenging, it is an impact crater area of the moon, and it is also considered to be the oldest area on the moon.
And the mainland challenges this region because it feels that its scientific research value is higher. It is expected that mankind will have a greater understanding of the moon, at least the history of the moon's formation, evolution, etc.
Of course, in fact, the most critical point, from my personal point of view, may be more looking forward to the exploration of lunar resources, because there are too many rare resources on the moon, if we can grasp its main distribution through lunar sampling, then the future mainland to establish a lunar base, the establishment of a lunar habitation, etc., have a certain reference.
So, the far side of the moon is not what NASA Administrator said, the far side of the moon is permanently dark (wrong statement), I don't know what China is going to do, and the United States does not plan to go.
When China collected samples from the far side of the moon and achieved a breakthrough, NASA administrator knew how "comedy" his statement was.
Therefore, looking forward to the complete success of China's Chang'e-6 mission, what time are you waiting for?
First, because Chang'e-6 adopts a retrograde lunar orbit, its flight direction is opposite to the rotation direction of the moon, which requires the orbiter to be better stabilized in the orbit around the moon, and to avoid changing the installation position of the probe's solar wings, sensors and other devices, which must be adjusted.
Second, the far side of the moon is not as flat as the front side of the moon, and the selection of landing areas and precise landing are one of the difficulties of the mission.
In the process of flying around the moon, E-6 needs to adjust to the ideal landing area through a variety of technical means during the landing process on the moon.
Third, it is necessary to explore the structure points of the lunar sampling area in advance, because the superficial structure of the moon under the lander is not clear, so it is necessary to wait until the Chang'e-6 probe arrives on the moon and the specific situation can be known with the help of the probe.
Therefore, these three key points need to be prepared in advance in the orbit of the continent around the moon.
You haven't seen more news about Chang'e-6, and it may be that you are preparing for these.
Of course, there are also issues such as the commissioning of the continental Queqiao-2 relay satellite, which are all done in the orbit around the moon, you can think about it, in fact, there are still many tasks, and it is not as simple as everyone thinks, which is why it takes longer to sample the lunar front than the continental Chang'e-5 lunar front.
Now you understand, right? In fact, it is waiting for the "opportunity" for the end of the adjustment, and if this time is not grasped well, the difficulty coefficient of the Chang'e-6 mission will be increased by another level.
In fact, this also reminds me of one thing, that is, one of the factors why no country has gone to the far side of the moon for so many years.
Because the far side of the moon is really difficult, what is the core problem?
That's right, humans have taken 10 lunar samples, but all of them are on the front side of the moon, and the missions on the far side of the moon are all from China.
Chang'e-4 was on the far side of the moon, but no samples were taken.
The fact that Chang'e-6 went to the far side of the moon to conduct lunar sampling shows that China is carrying out difficult missions to advance the mainland's space technology.
Of course, in fact, in addition to the difficulties seen on the surface, there is a core point - there is no relay star, only China has a relay star in the world, and the United States itself also planned to go to the far side of the moon to carry out a mission, but there is no relay star, and it also applied to China to use it.
At that time, the mainland agreed to the U.S. application to use it, but when Chang'e-6 was on mission, NASA Administrator said he didn't plan to go. This indicates that it may not be used in the future.
Of course, in addition to the United States, other space-faring countries have also applied for it, and the mainland has also agreed.
Then, at least in terms of phased time, if other countries are still seen performing missions on the far side of the moon, then China's relay satellite participation may be indispensable, and here I will give you a few more words.
Of course, in the future, China's relay satellite will also build a "deep space network" system, after the launch of Queqiao-3, the signal transmission of "Earth-Moon Jinhuo" will be realized, and it will be a different situation at that time, which is more worth looking forward to, which also shows that China's Queqiao constellation construction is already on the way.
Therefore, the development momentum of China's aerospace industry is very strong, and the state that everyone has seen in recent years will get better and better. Of course, the most anticipated thing is to hope that China will complete the manned mission to the moon as soon as possible, which is also the first time for China, and this is the general situation.
