In the vast starry sky of the universe, the distance between the earth and the moon is simply insignificant.
But even this insignificant distance is still very far away for humans. Even the most advanced spacecraft will take several hours to complete it.
June 24, 2021, 3 pm.
On board the Houyi spacecraft, Li Haiyang, the captain of the moon landing team, woke up from his sleep. He had been training deliberately for a long time, so when the time came, his biological clock would automatically wake him up.
He looked at the time and saw that it was still 2 minutes away from the scheduled time. He did not disturb his teammates' sleep and looked forward.
In the field of vision, the moon is already very huge and can be seen clearly with the naked eye.
The moon is not represented by the moon palace in the mythology, and of course there is no Chang'e and the little white rabbit. Of course, Wu Gang, who cut down the osmanthus tree, is nowhere to be found.
On the contrary, the surface of the moon is very desolate, with craters of various sizes formed by meteorite impacts everywhere. Some craters are so huge that they have even formed huge basins, while some craters are very small.
Formed by the impact of meteorites.
Desolate, deserted, without any color, this is the original appearance of the moon.
Looking back at the direction of the earth, the earth has become very small at this time, just like a bright disk lying across the void. The blue light makes it look like a bright pearl, very dazzling.
, eye-catching.
"Buzz~buzz~"
At this time, there were sounds in the spacecraft, and the alarm clock was set to wake up the astronauts.
"Call Houyi from the ground~Houyi from the ground~Please answer if you hear it~"
Soon, the voice of the ground control command center liaison officer came from the headset worn by Li Haiyang.
"Houyi has received it~Houyi has received it~"
"Requesting instructions~"
Li Haiyang looked at his teammates around him. They had all woken up from their sleep and began to look energetically at the moon and back toward the earth.
"The spaceship will start to slow down in 5 minutes~ The spacecraft will start to slow down in 5 minutes~"
"Received~ The spacecraft will start to slow down in 5 minutes~"
Li Haiyang repeated what the other party said, and then everyone on the spacecraft became nervous.
Everyone knows that whether the spacecraft can be captured by the moon's gravity when it arrives at the moon is a very critical step, which is directly related to the success or failure of the manned moon landing plan.
Here at the ground control command center, scientists and engineers have also begun to get busy. Detailed information about the spacecraft is constantly updated, and supercomputers are constantly conducting simulations to ensure that it can smoothly decelerate to a speed that can be captured by the moon's gravity.
into lunar orbit.
Through the cameras installed inside and outside the spacecraft, the ground control command center can also clearly see everything inside and outside the spacecraft.
Everything went very smoothly~
The spacecraft and astronauts are in very good condition. As long as they can successfully enter the lunar orbit, the manned moon landing can basically be declared a success. After all, with the powerful capabilities of the anti-gravity spacecraft, it is impossible to land on the moon.
It's just a piece of cake.
Five minutes later, the deceleration engines on the two spacecraft began to decelerate. The deceleration engines also used fuel injection propulsion engines, but they were installed in the opposite direction.
As the deceleration engine started, a bright tail flame began to slowly lengthen and become brighter in front of the spacecraft, and the speed of the spacecraft also began to slowly and continuously decrease.
As it gets closer to the moon, the speed of the spacecraft becomes lower and lower.
Half an hour later, the moon was very close at hand. At this time, everything on the moon could be seen clearly even without any tools.
The air shown by the moon is very thin. Yes, there is still air in the moon, but it is not even one billionth of the air on the earth. The moon's gravity is too small to attract the air shown.
The air represented by the moon is so thin that it is no different from no air. Without the protection of the atmosphere, everything represented by the moon can be seen clearly in space.
It is precisely because there is no protection from the air that no matter how big or small a meteorite hits the moon, it can leave large and small impact craters on the moon.
The earth is very lucky. As a satellite of the earth, the moon is like a shield. It has withstood countless bullets from the stars and the universe for the earth. The bumpy surface of the moon is the best proof.
Without the moon, life on the earth might have been destroyed again and again by the impact of meteorites from outer space.
Of course, the earth's own thick atmosphere is also a protective umbrella. Small meteorites rub and burn with the atmosphere. When they actually fall to the earth, their mass will be much smaller. Many meteorites, as long as they are not particularly large, will not cause damage to the earth.
Too big a threat.
Under the dual protection of the moon and the atmosphere, the earth, the cradle of life, exists.
The spacecraft continued to decelerate, and by about 4 o'clock, the speed of the spacecraft had dropped to 2 kilometers per second, which was fast enough to be easily captured by the moon's gravity.
"Huh~"
Li Haiyang took a deep breath and looked at the huge moon outside.
At this time, the Earth Control Command Center has handed over the authority of the spacecraft to him. The distance between the earth and the moon is nearly 400,000 kilometers, and it takes 1.3 seconds for electromagnetic waves to propagate at the speed of light, and it takes 2.6 seconds to travel back and forth once.
This seemingly insignificant time difference may very well lead to fatal mistakes.
Therefore, the control of the spacecraft at this time is in the hands of the astronauts on the spacecraft. They need to make timely judgments based on their past training experience to successfully fly the spacecraft into the lunar orbit.
Li Haiyang carefully drove the spacecraft slowly towards the moon. Soon, the spacecraft was smoothly captured by the moon's gravity and began to enter the orbit around the moon, flying continuously around the moon.
Immediately afterwards, the 'Chang'e' spacecraft also entered the lunar orbit very smoothly, and also began to continuously orbit the lunar orbit.
"Hou Yi called the ground, Hou Yi called the ground, and successfully entered the lunar orbit~"
"Chang'e called the ground, Chang'e called the ground, and successfully entered the lunar orbit~"
When the news that the two spacecrafts successfully entered the lunar orbit was transmitted back to the ground control and command center, the entire ground control and command center couldn't help but cheer.
Qin Yi, who had been doing nothing all this time, couldn't help but stand up with everyone and started clapping continuously.
It entered the lunar orbit very smoothly, which basically means that there are no problems with this moon landing. The next step is to wait for time. When the time is up, the spacecraft will fly into the moon, and the descendants of Yan and Huang will set foot on this magical land.
It was around 4 o'clock when the spacecraft arrived in the lunar orbit, and the actual moon landing was at 6 o'clock. There were 2 hours of busy work in the middle.
Inside the Houyi spacecraft flying in lunar orbit, the nine astronauts began to get busy.
The orbit of the spacecraft was constantly adjusted. At the same time, the hatch of the spacecraft slowly opened, and satellites were continuously released one after another. A lunar global positioning system was soon established on the moon.
With large anti-gravity spacecraft, launching satellites is really no different from eating. It is simple and not difficult at all. Building a lunar positioning system is just a matter of launching dozens of satellites.
The establishment of the lunar global positioning system is also for the follow-up plan. These satellites can not only position, but also be used for communication. In the future, bases, mining bases, lunar factories, etc. on the moon will need to use this positioning and communication system.
Of course, communication satellites, resource exploration satellites, etc. have already been launched on the moon side, and there are even several unmanned spacecraft filled with supplies that have been launched in advance.
These spaceships are ordinary spaceships, not anti-gravity spaceships, and they are filled with various materials.
When the time comes, the two spacecrafts will unload the materials in the spacecraft to the moon, and then they can fly into space to transport these materials.
To build a permanent base, the materials required are still too large, and people will be stationed behind for a long time, so the materials should be prepared as much as possible.
Of course, this is only when you have an anti-gravity spacecraft. Without an anti-gravity spacecraft, everything must be carefully calculated, and it is simply impossible to have such a luxury of loading up spaceships one after another in advance.
The two spacecraft on the moon side are constantly busy.
Here on Earth, it’s time to get off work in China. On this day, almost all companies, units, etc. got off work half an hour early, leaving time for everyone to watch the live broadcast of the manned moon landing.
This is a great moment for the entire country, and it is also a great moment for the people of Yan and Huang. 1.4 billion people across the country, as well as overseas Chinese and compatriots of Chinese descent, are witnessing this great moment.
Companies and factories got off work early, and schools ended early. Even the senior high school students who were most pressed for time and were about to take the college entrance examination put down their pens and books at this time and sat in front of the TV, preparing to watch the manned moon landing.
Holy moment.
From the country's leaders to ordinary people, everyone stopped what they were doing.
Adults hold ignorant children and very patiently and proudly tell their children what the moon is and what manned landing on the moon means. When these children grow up, they will understand that the strength of this country and the national pride will be
Deep into the bone marrow and soul.
Overseas Chinese people gathered together, laid out fine wine, and waited for the moment to toast and celebrate.
