After Chang'e-6 entered the orbit around the moon and separated from Pakistan's "CubeSat", it sent back a photo of the moon and the sun, which instantly made many people "uncomfortable", because this photo should not be the same.
Some netizens said, "It won't be just these three photos", some netizens said, "Is it so cost-effective", and some netizens said, "The pictures are too mushy, it's difficult to connect with high-tech" and so on.
Anyway, it's for the photos taken this time, which is a bit incredible. At the same time, when taking photos, many netizens were also saying, why have you been circumnavigating the moon and how long will it take to land on the far side of the moon? Let's take a look at it step by step.
Bacube photo blurry? What's with?
Indeed, this photo is really not good, it is blurry, this is the truth, at least in the eyes of the public, this photo is really not good, it is difficult for people to distinguish the level, whether it is good or not, everyone knows according to the actual photo comparison.
CubeSats so bad? Indeed, this CubeSat is very special, strictly speaking, it does not belong to Pakistan independently developed, it is researched together with the mainland, this is China's first lunar exploration satellite under 10 kilograms, made in Shanghai, "Pakistan Railway" use.
The SJTU Siyuan-2 lunar exploration satellite, developed by a team of teachers and students from the School of Aeronautics and Astronautics of Shanghai Jiao Tong University, is a "friendship star" belonging to China and Pakistan, and is named ICUBE-Q as an international cooperation payload.
Therefore, it is a joint project, however, although this satellite is a small satellite of less than 10 kilograms, which is the smallest "nanosatellite", and the weight of the whole satellite is only 6.5 kilograms, but its function is still good, in addition to everyone being able to see and take pictures.
It can also carry out the verification of new technologies such as intelligent processing of in-orbit image data, space test of stainless magnesium alloy electric control box shell, nanosatellite-level deep space moon-to-ground communication, etc., and fully explore the low-cost deep space exploration mode based on micro-nano satellites.
So, the strength is still quite good, then I wonder, so powerful, why are the photos so bad and blurry? From a personal point of view, there are two main points:
First, this satellite is too small and fully functional, but when it comes to each part, the space station it occupies must be limited, you say that the weight of the whole satellite is only 6.5 kilograms, how much ultra-clear camera do you want to carry? Unlikely.
Therefore, it is unlikely that the camera is very strong, and the fact is that this satellite is equipped with two 1 280 × 720 pixel cameras, and it is completely normal to shoot such an effect.
Second, the angle from which the photo is taken may have an effect, because it is an optical camera, which happens to be photographed together with the opposite sun and the moon. So, when you see a spot of light in the photo, it's a reaction of the camera.
So, these two factors may be the factors that cause the photos to be less clear, at least that's what I personally think, just take a look.
And for the entire cooperative CubeSat, in fact, the function is still good, and some data may be released in the future, and the design life of the entire satellite is also 3 months, you can look forward to it, this is the general situation.
Why is Chang'e-6 still orbiting the moon, and how long will it take to land on the far side of the moon?
Indeed, since the mainland announced that Chang'e-6 had entered orbit around the moon, it has announced the release of CubeSats and the taking of photos, but there is not much news about Chang'e-6. So why is Chang'e-6 still orbiting the moon, and how long will it take to land on the far side of the moon? I'll just explain this to me.
After Chang'e-6 enters the orbit around the moon, it does not mean that it will land directly on the surface of the moon, in the process of circum-moon, there are more tasks to perform, so it is unlikely to land on the far side of the moon so quickly, in the circumlunar stage, Chang'e-6 will take about 20 days to adjust its position to prepare for the moon landing.
In this 20-day or so, in addition to the CubeSat missions that have already been carried out, there will be many orbit changes to finally enter the orbit of 200X200 kilometers before entering the landing stage.
At the same time, in addition to the orbit change, it is also necessary to carry out the test of the Queqiao-2 relay satellite, because this time the continent is on the far side of the moon to sample and return, without which the mission cannot be completed.
Therefore, before the mission, to connect the relay satellite, Chang'e-6 will conduct many tests, and after ensuring that nothing goes wrong, it will carry out separation, landing, etc., which will take time to complete.
This is also why the entire Chang'e-6 mission on the mainland will be carried out in 53 days, which is completely incomparable compared to the 20-day time of Chang'e-5. This also shows that in fact, the Chang'e-6 mission is not so simple, so how long will it take to land on the far side of the moon?
According to the approximate time node, you can see that it is expected that the upper assembly will be separated from the orbital return assembly on June 1, and the upper assembly will land on the moon on June 2.
Of course, after the sample returns, the mission will continue, and it is expected that it will be completely returned to the ground in late June, and the way home will be about 5 days of flight, re-entering the atmosphere, and returning to the landing site of Siziwangqi.
So, in fact, going to the lunar orbit and coming back from the lunar orbit, this time node is not long, mainly because there are more tasks in the process, which is the general situation.
If successful, Chang'e-6 will make history
That's right, for the Chang'e-6 mission, I personally believe that there is no problem, after all, China's success rate of lunar exploration is incomparable with other countries in the world.
But only if all the tasks are successfully completed, then it will also be announced.
And once the mission is successful and successfully concluded, it will not only create the history of China, but also create the history of the world, because this is the first time that human beings have taken samples on the far side of the moon, and humans have collected 10 lunar samples before, all of which were carried out on the front side of the moon.
Therefore, we are very much looking forward to the return of Chang'e-6 in late June to bring the first samples of the far side of the moon to mankind.
Previously, the director of NASA said that he did not know what China was doing on the far side of the moon, and he said the wrong thing - saying that the far side of the moon was dark and the United States did not plan to go.
When the time comes, after waiting for China to get it back, a research breakthrough has been made, and it is not like Chang'e-5, which is "cheeky" to apply for samples.
This time, China is a unique sample of the far side of the moon, and the research value is definitely higher, which will be able to pinnacle the new understanding of the moon by human beings, because the samples on the far side of the moon are more ancient, and they can let everyone know what the moon's past was like, and this is the general situation.
