Time passed quickly, and Zhou Yu, Feng Hai and others observed the preparations of other units and understood the situation of the main units clearly.

The time came to 6:55 p.m., and the Alxa Space Launch Center was about to begin transporting the standard module of the space station through mass projectors.

Feng Hai looked at Zhou Yu and said nervously: "Next, it all depends on the performance of your Xinghuo Technology, the standard module of the space station is successfully assembled according to the program, and our mission is 80% successful."

Zhou Yu patted Feng Hai's shoulder confidently, and said confidently: "Don't worry, we have been preparing for this moment for a long time. Considering every detail, I am confident that no matter what the situation, we can get it right the first time. ”

Lu Jinming's figure appeared on the screen of the space command center.

He took a flying car from Yanjing to the Alxa Space Launch Center, and immediately began to arrange the launch mission of the space station.

Xinghuo Space has rehearsed the launch mission many times, and the engineers are steadily operating every step of the process, and their demeanor is very relaxed.

Lu Jinming reported: "We have completed the preparation, have not found any problems, and requested to start launching the standard module of the space station."

Zhou Yu nodded at him and said, "Permission to launch the standard module of the space station, and report any problems at any time."

With the issuance of Zhou Yu's order, the launch mission of the standard module of the space station officially entered the state of counting.

The relevant units of the space station plan can learn about the situation of the Alxa Space Launch Center through the system of the space command center.

Lu Jinming saw that the time had come to 7:00 in the evening, and he immediately gave instructions to the engineer.

"Mass projector ignition."

"The mass projector was successfully ignited, and the standard module of the Nong-1 space station began to be launched."

"The cargo box was successfully pulled by the moon's gravity, and the standard module of the Nong-1 space station flew to the designated orbit."

"The cargo box flight attitude is normal, and the telemetry signal tracking is normal."

……

"The standard compartment cargo box of the Gong-3 space station was ignited and launched."

"The gravitational capture of the moon failed, and the cargo box began to land in the desert."

"The parachute has been successfully opened, and a search team has been dispatched."

"The project has been postponed in order, and the standard module of the Yan-1 space station is ready to be launched."

Zhou Yu stared at the mass projector cargo boxes that were constantly flying into the universe, some of which failed to launch and could only be pulled back to the Alxa Space Launch Center by car.

After overhauling them, they were re-fired again.

The standard module of the space station is very expensive, and even if the country has huge financial resources, it can only make one for each type of space station standard module.

Xinghuo Technology can only use various methods to ensure the safety of the standard module of the space station when the cargo box is not pulled by the gravitational pull of the moon.

The space station is composed of a total of 24 standard modules, which are four types of standard cabins: living module, agricultural module, industrial module and scientific research module.

Among them, there are five living cabins, three agricultural cabins, five industrial cabins, and eleven scientific research cabins.

At the Alxa Space Launch Center, when inspecting the standard modules of the nine space stations that failed to launch for the first time, the standard modules of the space station that were launched first have come to the established orbit.

The orbital altitude of the space station is 430 km in low-Earth orbit.

It is very close to the ground compared to communication satellites, which is why the mass projector cargo box can be reached quickly.

Feng Hai stared nervously at the picture transmitted back by the cargo box.

"I wish the assembly of the standard module of the space station all the best.

Launch the standard module of the space station into the designated orbit. I understand the capabilities of mass projectors, which can be done easily.

In the whole process of building a space station, the most difficult thing is to assemble the standard module of the space station, and the more you go to the back, the more difficult it is to assemble. ”

The standard module of the space station is in low-Earth orbit, which is operating at a speed of 7.2 kilometers per second.

The standard cabin is moving at extremely high speeds, and the kinetic energy it carries is enormous.

Once the two standard cabins did not fit together during the first docking process, they were perfectly assembled in a short time.

The standard modules of these two space stations will be damaged directly due to the high-speed impact.

Zhou Yu saw Feng Hai's worried eyes, and he comforted: "The standard cabin of the space station, this is the equipment designed and produced by our Xinghuo Technology and many domestic scientific research units.

We have made perfect preparations for the assembly of the standard module of the space station, which can ensure that the assembly is successful every time. ”

Feng Hai calmed down when he heard Zhou Yu's introduction, and watched the movements of the mass projector cargo box.

After the mass projector cargo box reaches the designated orbit, it begins to release the standard module of the space station.

The mass projector cargo box is still connected to the standard module of the space station with metal ropes to direct the movement of the standard module of the space station.

The standard module of this space station adjusts its position in low-earth orbit.

Other space station standard modules have come to the vicinity of this space station's standard module.

Xinghuo Aerospace has already calculated the orbital position of the standard module of each space station.

The mass projector cargo box of the later launch will directly send the standard module of the new space station to the vicinity of the standard module of the space station that was launched in advance.

Five living modules form the main structure of the space station, and the standard module of the Sheng-1 space station and the standard module of the Sheng-2 space station begin to dock.

The docking of the two space station standard modules is done by a computer inside the cargo box of the mass projector.

By calculating the attitude of the standard modules of the two space stations, the docking part of the two standard modules of the space station is kept relatively stationary while the docking site is stable.

In response to the docking problem of the standard module of the space station, Xinghuo Technology has developed a completely passive mechanical structure.

Through a passive light sensor, the docking of the two space station standard modules has an error of less than 10 microns.

At the moment of docking, the mechanical structure responsible for docking immediately locked, allowing the two space station standard modules to complete the docking work.

Zhou Yu saw that the space station was like building blocks, splicing the standard modules one by one to the space station that was gradually taking shape according to the established procedures.

Only by docking all the standard modules of the space station can a space station that meets the requirements be formed.

The construction of the space station is in an advanced stage, and it is becoming more and more difficult to maintain a standard posture due to the influence of the space station's own structure.

The standard module of the space station installed in the later stage not only has to find its own docking position, but also adjusts its attitude at all times to prevent collision with other standard modules.

After two days and two nights of docking, all the standard modules of the space station were docked and officially established as a space station.

Feng Hai saw that the space station was officially formed, and he breathed a sigh of relief and said: "The construction of the space station has finally been completed, and the biggest difficulty in the space station plan has passed."

Zhou Yu also smiled and said: "This success has accumulated enough experience for us, and I believe it will be easier in the future."

But now is not the time to relax, and we do not yet know if the standard module of the space station can be successfully launched.

It is very difficult to install the standard module of the space station, but it will be even more difficult to replace the standard module of the space station. ”

Feng Hai excitedly pressed the button in the control center.

"Activate the standard module of the space station, and the space station performs a self-test."
