Chapter 220 219 The Coincidence of the Moon

Seeing what Chen Jue said, the three of Wang Zhihai also breathed a sigh of relief, took some nutritional supplements and handed them over, and even said a few words of hard work, and then chatted while floating in the space station. The intelligence information informed Chen Jue.

You must know that apart from the necessary physical fitness for astronauts who can be on the space station, each of them has a level of professional knowledge that can be called a doctoral level.

Whether it is general astronomy, mathematics, physical astrophysics, aerospace, communication and navigation, etc., he is extremely proficient.

What Chen Jue learned in the base before was mainly related to the structure of the human body, as well as knowledge of physics, radiant energy, electromagnetics, quantum mechanics, etc. He was indeed lacking in astronomy, so he learned a lot from talking with these three people.

You must know that the place where Chen Jue needs to land this time is not on the front side of the moon, but on the back side of the moon, which is more complicated and difficult than Eagle Country's moon landing in the 70s and [-]s.

Because the moon does not rotate like other satellites that orbit outside the planet. Its rotation is very special, and its revolution period is highly coincident with one month, with only one fixed side facing the earth.

Stars, planets, and other non-artificial satellites such as the sun and the earth that we are familiar with basically have time and angle differences between revolution and rotation, so we can observe their different sides.

Only the moon is different. It always faces the earth with one side, which makes it extremely difficult for humans to observe or land on the back of the moon.

The perigee straight-line distance from the earth to the moon is about 384403.9 kilometers, but if you want to go around the back of the moon, this distance will be greatly lengthened.

Just like us ordinary people walking, it is always the easiest to walk a two-point straight line, but once you take a long way around, the situation is different.

In addition to the need to arrange staged relay communication satellites in advance to avoid communication signals being blocked by the moon itself, the fuel and endurance of the lunar landing spacecraft will become more demanding.

This is why, since the Eagle Kingdom in the 70s and 6s, the six manned landings on the moon have only reached the front of the moon, but never attacked the back of the moon.

As for why the moon always faces the earth, Ye Guangming, who is good at theoretical knowledge, described to Chen Jue that there are several conjectures in the scientific community, and the most mainstream and recognized one is the big collision hypothesis at the beginning of the moon's birth.

This hypothesis holds that the earliest moon was not what it is now, but had a normal speed of rotation like the satellites of other planets.

However, after another strange celestial body collided with the early moon, it caused the rotation of the moon to brake, forming a very coincidental duality of the moon.

There are many evidences to support this hypothesis. The first is that the front of the moon is flat, while the back of the moon is uneven.

Then there is the lunar soil obtained by lunar exploration. The composition of the lunar soil collected from the front of the moon is completely different from that collected from the back.

It's like two plasticines collided together. Except that a large number of debris meteorites fell into the earth or splashed into space during the collision, the remaining main parts fused together and became the current moon.

In addition, there are several other evidences to prove this big collision hypothesis, that is, ancient meteorites with the same composition as the lunar soil on the back of the moon were collected from the earth.

This time, the collision of celestial bodies that happened countless years ago caused the rotation of the moon to brake, shortening the distance between the earth and the moon. It is gradually moving away from the moon at a rate of 3.8 centimeters per year.

After listening to Ye Guangming's description of the origin, birth, and conjecture of the moon, Chen Jue's mind came up with those meteorites that fell on the earth, including the congenital Qi, and the content related to the moon that appeared in myths and legends from ancient times to the present. , thinking sparks flew, and thought: "The front is always facing the earth... The moon in ancient times was closer to the earth... Is all this really a coincidence?"

……

After chatting with the three of them for a long time, Wang Zhihai, Liu Yaming, and Ye Guangming all showed a bit of envy when they learned that Chen Jue would take a lunar landing spacecraft on the back of the moon in a few days.

Human yearning for landing on the moon has always been hidden in the bones. Countless people have fantasized about the moon since ancient times.

Especially in the fairy tales of the flower growers, from Chang'e flying to the moon to Wu Gang cutting the osmanthus, to the jade rabbit smashing medicine, etc., this is the romance buried in the genes of the flower growers.

Any successful astronaut will dream of landing on the moon one day and leaving his footprints on the moon like Armstrong.

Just like ordinary people like to play games, read novels, and like to collect achievements and badges, for flower planters, landing on the moon is a historical achievement that will last forever.

It's a pity that Chen Jue kept the whole process of landing on the moon secret. Although the ground monitoring hall will record video data, this information will not be released until a certain time.

Looking at the envious eyes of the three, Chen Jue smiled: "I am going to the moon in secret, the situation is different, the first moon landing that will be publicized in the future will still be handed over to you three to realize it. "

Hearing this, the three of them also nodded thoughtfully, obviously expecting it in their hearts.

……

After sitting and chatting with the three astronauts for a long time, they heated up the space food.

For the flower growers who are foodies, even the aerospace food sent to space is varied, with more than 120 varieties.

Of course, it’s not about eating indiscriminately. From the first day of stationing in the space station, you must eat according to science, and you need a reasonable mix of nutrition.

However, Chen Jue has a special physique, and he can use the state of [Golden Toad Swallow Qi] to speed up gastrointestinal peristalsis. After eating some aerospace food while sitting, he felt that his body was being exhausted in the fight against too fast radiation, so he ate some more The latest version of human nutrition specially provided by the base brought up.

After eating, several people began to rest separately, while Chen Jue floated in the cabin and started his daily practice.

Cultivation lies in practice, and practice lies in diligence, just like sailing against the current, if you don't advance, you will retreat.

In the special environment of space, Chen Jue was extraordinarily diligent in practicing Kungfu, because he could see the proficiency of [Red Dust Golden Body Kung Fu] beating on the attribute panel all the time.

In addition, Chen Jue's growth rate of free attribute points is also accelerating. Usually, 0.20 a day is almost the limit. After going to space, it actually reached 0.30 a day.

In addition, due to the influence of space radiation, his lifespan is being consumed at an accelerated rate, which also stimulates his desire to practice, so that he can practice against negative space radiation.

……

For the next two days, Chen Jue spent leisurely time in the space station. In addition to going out of the cabin twice to further strengthen his adaptation to the space environment, and seeing the magnificent and round earth a few more times, Chen Jue always thought that if he could take pictures Just post it on Moments, and just edit a title with "Thank you for the invitation, I just got off the rocket, and I'm in the space station", which will definitely get a lot of likes.

It is even possible to blow up the circle of friends and get on the Internet.

It's a pity that my mobile phone has been placed in the dormitory of the base, and I can only turn it on when I go back.

During the two days, Chen Jue also learned a lot of relevant knowledge from the three astronauts, and he waited until noon on the third day.

The lunar spacecraft launched from the base successfully docked with the space station, and Chen Jue stopped his leisurely life on the space station. Together with the three astronauts, they moved all the first batch of materials into the lunar spacecraft, and Chen Jue put on He took off the special heavy spacesuit and got into the lunar spacecraft.

But Wang Zhihai, Liu Yaming, and Ye Guangming were at the meeting point, and saluted Chen Jue: "Comrade Chen Jue! Take care!"

"I wish you a smooth journey and a safe return soon!"

"I also wish you all return home safely as soon as possible!" Chen Jue nodded to the three of them with a smile, and waved his hands. After a few days of getting along, we all became good friends. It's short of a sensational farewell.

Chen Jue reached out to close the hatch of the lunar landing spacecraft and set the locking procedure. Then, under the remote control of the ground monitoring hall, the lunar landing spacecraft separated from the space station and began to head straight for the moon more than 38 kilometers away.

　The first one is delivered!I went out to do errands during the day, and I delayed the update, so I will make it up at night~ Stay up all night to add more updates.Modified some content and polished it up
