Seeing Chen Jue say this, Wang Zhihai and the three of them also secretly breathed a sigh of relief, took some nutritional products and handed them over, and said a few hard words, and then chatted while floating in the space station, and informed Chen Zhi of some intelligence information about the space station and lunar exploration.

You must know that in addition to the necessary physical fitness, the level of professional knowledge of each of them can be called a doctorate in addition to the necessary physical fitness.

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

Chen Jue's previous studies in the base were mainly related to human body structure, as well as physics, radiation energy, electromagnetism, quantum mechanics and other knowledge, and he was indeed a little lacking in astronomy, and he gained 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 far side of the moon, which is more complicated and difficult than the situation of the Eagle Kingdom landing on the moon in the sixties and seventies of the last century.

Because the Moon does not rotate like other moons orbiting outside the planets, its rotation is very special, and its orbital period coincides with a high degree of one month, with only one fixed side facing the Earth.

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

The only thing is that the moon is always facing the Earth, which makes it extremely difficult for humans to observe or land on the far side of the moon.

The distance from the Earth to the Moon is about 384,403.9 kilometers in a straight line, but if you want to go around the far side of the Moon, then this distance will be greatly extended.

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

In addition to the need to deploy phased relay communication satellites in advance to avoid the communication signal being blocked by the moon itself, the fuel and endurance of the lunar spacecraft will become harsh.

This is also why, since the six manned landings on the moon in the sixties and seventies of the last century, the Eagle Country has only reached the front side of the moon, and has never attacked the far side of the moon.

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

This hypothesis is that the original Moon was not what it is now, but rotated at a normal speed like the moons of other planets.

However, after another unfamiliar celestial body collided with the initial moon, it caused the moon's rotation and brake, forming a very coincidental two-sided moon.

There is a lot of evidence to support this hypothesis, the first of which is that the front side of the Moon is flat and the far side of the Moon is pitted.

After that, there is the lunar soil obtained by lunar exploration, and the composition of lunar soil collected from the front side of the moon is completely different from the lunar soil collected from the back side.

It's like two plasticines colliding together, except for a large amount of debris that meteorites are produced when they collide, falling into the earth or splashing into space, the remaining main parts are fused together and become the current moon.

In addition, there are several other pieces of evidence to support the Great Collision hypothesis, which is that ancient meteorites of the same composition as the lunar soil on the far side of the Moon have been collected from Earth.

This celestial collision that occurred countless years ago caused the moon to rotate and brake, narrowing the distance between the Earth and the Moon, and some of the debris that fell off from that strange celestial body also hit the Earth, slowing down the Earth's self-rotation, which further caused the Earth and the Moon to form a speed of 3.8 centimeters per year and gradually move away.

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 congenital meteorites, as well as the moon-related content that appeared in myths and legends from ancient times to the present...... Is all this really a coincidence? ”

After talking with the three of them for a long time, after learning that Chen Jue would take a lunar spacecraft to sit on the far side of the moon in a few days, Wang Zhihai, Liu Yaming, and Ye Guangming all showed a little envy.

Human beings' yearning for the moon landing is already hidden in their bones, and countless people have fantasized about the moon since ancient times.

Especially in the mythical stories of the flower planters, from Chang'e running to the moon to Wu Gang cutting Gui, to the Jade Rabbit pounding medicine, etc., this is the romance buried in the genes of the flower planters.

Anyone who has made it to the astronaut dreams of landing on the moon one day and leaving his footprints on the moon like Armstrong.

Just like ordinary people play games, read novels, and like to collect achievements and badges, for the flower planting family, the moon landing is a historical achievement that will go down through the ages.

It's a pity that Chen Jue's moon landing this time was kept secret throughout the whole process, although the ground monitoring hall will record the video data, but this information will not be released to the public until a certain time.

Looking at the envious eyes of the three of them, Chen Jue smiled: "I am secretly landing on the moon in secret, the situation is different, and the first moon lander to be publicized to the outside world in the future will still be handed over to the three of you to realize." ”

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

After sitting and chatting with the three astronauts for a long time, several of them started to heat up the space food.

For the flower-growing family who were born as foodies, even the space food sent to space is varied, with more than 120 varieties.

Of course, it is not eaten indiscriminately, and it must be eaten according to science from the first day of stationing on the space station, and it needs to be nutritionally reasonable.

However, Chen Jie's physique is special, and he can use the state of [Golden Toad Swallowing Qi] to accelerate gastrointestinal peristalsis, and after sitting and eating some aerospace food, he felt that his body's consumption was intensifying in the fight against too fast radiation, so he ate the latest version of the human nutrition special supply from the base that he brought up.

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

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

In the special environment of space, Chen Jue practiced extremely diligently, because he could see the proficiency of the [Red Dust Golden Body Skill] on the attribute panel beating all the time.

In addition, Chen Jie's speed of increasing free attribute points is also accelerating, and it is almost the limit to be able to brush 0.20 a day, but after going to space, it has actually reached the level of 0.30 per day.

In addition, due to the influence of space radiation, his lifespan is being consumed at an accelerated pace, which also stimulates his desire to practice to combat negative space radiation.

In the next two days, Chen Jue spent a leisurely time in the space station, in addition to going out of the capsule twice to further strengthen the adaptation to the space environment, and taking a few more glances at the magnificent and mellow earth, Chen Jue always thought that it would be good if he could take a photo and send it to a circle of friends, and casually edit a title of "Thank you for the invitation, just got off the rocket, and you are on the space station", which can definitely deceive a large wave of likes.

It is even possible to blow up the circle of friends and become popular 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.

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

The moon landing spacecraft launched from the base successfully docked with the space station, Chen Jue stopped this leisurely space station life, and together with the three astronauts, all the first batch of supplies were moved into the moon landing spacecraft, and Chen Du changed into the special heavy spacesuit and got into the moon landing spacecraft.

And Wang Zhihai, Liu Yaming, and Ye Guangming were facing each other, saluting Chen Jie: "Comrade Chen Jie! Take care!"

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

"I wish you all a safe return home soon!" Chen Juechong smiled and nodded, waved his hand, everyone has become good friends after a few days of getting along, what to say and what to talk about is almost the same, and it is not bad for this moment of sensational goodbye.

Chen Jue stretched out his hand to close the hatch of the lunar spacecraft, set up a locking procedure, and then under the remote control of the ground monitoring hall, the lunar spacecraft separated from the space station and began to go straight to the moon more than 380,000 kilometers away.
