The rise of nanometers

After some orbital maneuvers, the Chang 12 launch vehicle completed the separation of the core first stage.

At this time, the core first-stage rocket uses the remaining fuel to readjust its flight trajectory and prepares to return to the Mongolian spacecraft landing site on the ground from a low-Earth orbit of 400 kilometers.

The second and third stages of the core continue to maneuver towards a higher orbit.

After exhausting the fuel in the second stage of the core, the spacecraft finally arrived at a low-Earth orbit of 452 kilometers and completed orbit adjustment. This is the target orbit of this mission.

The ground command center of Dongfeng Space City.

"Report, it has arrived at the predetermined orbit."

"Start unfolding the capsule and pay attention to the orbital flight direction."

"Received, Experimental Cabin No. 1 begins to unfold..."

In the low-Earth orbit 452 kilometers away from the Blue Star surface, the remaining core three stages are the equipment for this space mission.

The fairing of the spacecraft has separated from the core three stage together with the core two stage.

The entire spacecraft consists of six space capsules, namely: core module, transportation and control module, No. 1 experimental module, No. 2 experimental module, No. 3 docking module, and No. 4 resource module.

Among them, the core cabin has the largest volume and weight, with a volume of 70 cubic meters and a weight of 23.5 tons. It stores 5.4 tons of N20 fuel and has an internal movable space volume of 32 cubic meters.

The core module is used as the power core, emergency escape module, astronaut lounge and restaurant of the space station.

The traffic and control module, as the space module that communicates with the core module, experimental module, docking module and resource module, has a volume of 25 cubic meters, a weight of 7.5 tons, and an internal activity space of 11 cubic meters.

In addition to its transportation function, this space capsule also has communications, computers and space station master control, as well as three battery systems. The weight of these three battery systems reaches 1.85 tons.

The remaining Experimental Module No. 1, Experimental Module No. 2, Docking Module No. 3, and Resource Module No. 4 have a total weight of 22.3 tons, including four special solar panels.

When the solar panels installed on the docking module and resource module are fully deployed, in the open outer space, there is no sunlight weakened by the atmosphere, shining on the solar panels, and the composite solar panels continuously generate electricity. Provide sufficient power for the battery system, radiation cooling system, and electrical equipment of the transportation cabin.

There are two experimental cabins, the No. 1 experimental cabin is the space biological experimental cabin, and the No. 2 experimental cabin is the space material experimental cabin.

The docking module, as the name suggests, is used for docking future spacecrafts and is equivalent to an extension of the transportation module.

The resource module stores 1.3 tons of supplies, which are the daily necessities of the astronauts. It also serves as a bathroom.

After trial operation of various equipment of the Tiangong Space Station, a burst of warm applause erupted from the ground command center of Dongfeng Space City.

"I declare that this launch mission has been successfully concluded."

The astronauts present, after cheering and congratulating each other, got back to their intense work.

The Tiangong Space Station was successfully put into orbit. Each space capsule and battery panel were deployed at the same time, and a preliminary trial operation was carried out. The next step was to transfer control of the space station to a specialized space station command center.

Several academicians from the Spaceport are already inside the space station command center.

Li Feng, the designer of Experimental Cabin No. 1, looked at the busy control center and asked anxiously: "Lao Wang, have you handed it over yet?"

"It's coming, it's coming." Although Academician Wang was also anxious, he had experienced many ups and downs in the past few decades, so he was not too happy.

Twenty minutes later, the person in charge of the space station control center trotted over and announced the good news to everyone happily: "The handover has been successfully completed. Now the control of the Tiangong Space Station is with our control center."

Li Feng was very excited, and his words were full of uncontrollable joy: "Okay, okay, let's do another test run immediately to see how each space capsule operates."

"clear."

The Tiangong Space Station is undergoing trial operation testing again.

On the other side, several heads of scientific research groups from the Academy of Sciences were also in the space station command center. When they saw that the Tiangong Space Station had stabilized, they immediately felt relieved and began to discuss arrangements for conducting experiments.

Although astronauts will have to wait until November this year to go to the space station, some of the biological experiments in Experimental Module 1 have actually been designed on the ground.

For example, the experimental planting box of the space plant planting experiment already has seeds inside. Under the set light, humidity and temperature, they will soon take root and sprout.

There are also space radiation experiments on plant seeds and space survival experiments on mice, all of which have breeding boxes and planting boxes set up in advance.

After discussing the experiments, the leaders of several space biological experiment projects began to communicate with the staff of the control center.

As the designer of the No. 1 experimental cabin, Li Feng participated in the remote experiment.

After a busy day, although the body is very tired, everyone's mood is excited and excited.

Putting down the trial operation report of Experimental Cabin No. 1 in his hand, Li Feng said with some pride:

"When the International Space Station rejected us, it thought it could stop us. Today we want to use actions to tell the world that even without them, we can still build the space station."

"The International Space Station will be decommissioned sooner or later, and I want to see the faces of those guys when the time comes."

"I heard that NASA has packaged some of its aerospace technology to a private company. It seems that they have realized that Lockheed Martin and General Electric are cheating."

"It's Elon Musk's Space Exploration Company. I heard it's doing well."

Hearing that they were talking about Elon Musk's Space Exploration Company, Academician Wang smiled and said: "We are also studying recyclable launch vehicles, but the cost performance is not high at the moment."

Li Feng suddenly thought of something: "The Americans have recently made a plan to return to the moon. What do you think?"

Academician Wang thought for a moment: "There are too many technologies required to colonize the moon. If there is no explosion of science and technology, there is not much hope for the lunar base to realize the possibility of permanent personnel before 2030."

Everyone also feels the same way. It is possible to send people to the moon with current technology, but the key is how the astronauts can survive on the moon for a long time after being sent there.

Low gravity and cosmic radiation in space are difficult problems for humans to completely solve in a short period of time.

On the International Space Station in low-Earth orbit, it is very troublesome to go back and forth. If it is permanently stationed on the moon, if there is no way for Blue Star to replenish it in time or replace the personnel, surviving on the moon for a long time is a difficult task for astronauts. Fighting for life.

Li Feng said with a smile: "If the Americans can't do it, maybe Xiuyuan's Suiren system can do it."

"Where is Xiuyuan?" Academician Wang was stunned, but did not refute. In their eyes, Huang Xiuyuan was indeed a miraculous existence.

Many of the current technologies of the Suiren system are difficult for ordinary people to develop in decades. Many technologies are enough to change an industry or even a country's strength.

"We can't always count on the Suiren Department. It's time for the various research institutes in the Aerospace Port to be reorganized." An old academician shook his head and said.

Academician Wang, Li Feng and others also agree with this idea.

The internal situation of the Aerospace Port does need to be further rectified to enhance internal vitality and competitiveness.

Fortunately, there is a catfish effect of the Suiren system, which has led to a talent shortage in various scientific research institutions in the country, which is conducive to the reform of scientific research institutions.
