The rise of nanometers

May 28th.

After a voyage that lasted 113 days, the Zhurong-class spacecraft 001 successfully reached the low-Earth orbit of Venus.

After some adjustments, the spacecraft stabilized on an 800-kilometer orbit. Cheng Lin, Wang Yunhai, and Qin Tianci were busy.

As soon as they arrived in the orbit of Venus, a strong solar storm gave the group a warning. Fortunately, the spacecraft had taken into account cosmic disasters such as solar storms, and no abnormal conditions occurred.

"Captain, everything is normal on the spacecraft!" Wang Yunhaihui reported.

Cheng Min nodded: "Okay." Then he turned around and said, "Tianci, report our situation to the Blue Star Remote Control Center."

"Understood!" Qin Tianci edited the email and sent it back to the Blue Star Ground Remote Control Center.

Half an hour later, the communication system popped up a reply from Blue Star Remote Control Center:

[Congratulations on your successful arrival at Venus, becoming the first pioneers to reach the orbit of Venus in human history. I also wish you success in your future work and good health - Venus Exploration Bureau of the Ministry of Aerospace]

In the next period of time, Cheng Lin and the others first built a 2,000-ton Taibai space station with a volume of 18,200 cubic meters according to the previous plan.

Some supplies and fuel were also transferred to the Taibai Space Station.

Although they are all modular in design, everyone still worked hard for more than two weeks to complete this task.

Finally, there are the remaining 2,000 tons of supplies, which are also the four aerospace modules prepared before. The weight of a single aerospace module is 400 tons, a total of 1,600 tons, and then 400 tons of fuel.

The floating modules are stored on both sides of the spacecraft.

Cheng Lin looked at the orange-red planet outside the window. This planet called "hell" will be where they will take the first step for mankind.

"emission!"

At the command, the engine of one of the floating modules spit out light red flames, and the tail flame became somewhat blurred against the background color of Venus' atmosphere.

The floating module has not been fully deployed at this time, and its size does not look too big.

Wang Yunhai, who is responsible for monitoring the speed and altitude of the floating module, always pays attention to various data.

The first part of the journey was very smooth, but as the floating module entered the 120-kilometer altitude area of ​​Venus, the density of the atmosphere here began to become denser.

And strong winds with wind speeds of 100 meters per second are the norm here.

The auxiliary engine of the floating module constantly adjusts the direction of the nozzle to offset the interference caused by strong winds. In the altitude area of ​​​​Venus, which is 80 to 120 kilometers above sea level, it is not suitable to deploy the floating module.

After several minutes of wrestling, aerospace module 0001 finally successfully reached an altitude of 60 kilometers.

"Start deploying the vacuum chamber."

"receive."

The radio wave brought instructions, and the system of the floating module automatically started and began to unfold the vacuum chamber shell.

At the same time, the auxiliary engine of the aerospace module began to activate reverse thrust to slow down the descent of the aerospace module.

After waiting for the floating module to expand 20% of the vacuum chamber, the altitude of the floating module has dropped to an altitude of 45 kilometers.

At this time, the expanded 20% vacuum chamber begins to evacuate the gas in the vacuum chamber. The vacuum chamber generates buoyancy, allowing the floating module to float in the air.

Since the total weight of the current floating module is only 467 tons (67 tons is reserved fuel), the vacuum chamber does not need to be fully expanded.

After all, the maximum load-bearing capacity of a single floating module is about 9,000 tons, which is not that much load-bearing. If all the vacuum chambers are deployed, the result will be excessive buoyancy and it will float directly to an altitude of 60 to 70 kilometers.

Doing this not only wastes buoyancy, but also wastes the fuel of the floating module.

With the first floating module successfully suspended at an altitude of 47 kilometers in the atmosphere of Venus, Cheng Lin and others pursued the victory and launched the remaining three floating modules into the atmosphere of Venus one after another.

Then start assembling it, with the first module as the center and the other three modules spliced ​​on the three sides.

The planar shape of the floating module is a regular hexagon, which is just enough to form a relatively stable whole.

the other side.

A Pioneer-class spacecraft that arrived at Venus one and a half months earlier than the Zhurong-class spacecraft 001 carried a 420-ton carbon powder energy storage generator set.

Next, Cheng Lin and others need to operate the striker-class spacecraft to place the carbon powder energy storage generator module into the floating city.

These functional modules are designed in advance and can be directly connected like building blocks.

Over at Blue Star, the Zhurong-class spacecraft No. 002 also set off from Blue Star's low-Earth orbit a month ago and will arrive in the orbit of Venus in 127 days to join Cheng Lin's team.

However, the Zhurong-class spacecraft No. 002 is an unmanned spacecraft, and the materials on it are only 3,300 tons.

The reason why the weight of materials transported by the same spacecraft is different is mainly because the distance between Venus and Blue Star is expanding little by little.

This is also a very normal thing in interstellar navigation between planets.

After all, the Venus Opposition takes several years, and in order to develop Venus as quickly as possible, the Federation naturally cannot launch a spacecraft every few years.

When launching a spacecraft during a non-big impact period, fuel consumption will naturally need to be greatly increased. This is a reality that must be faced.

Fortunately, this time, Zhurong-class No. 002 carried wind turbine modules, N30 fuel manufacturing modules, and a vacuum airship transport ship.

As long as Venus's N30 fuel can be mass-produced, when the spacecraft goes to Venus, the fuel it needs to carry can be reduced by about 40%.

The fuel reserve is reduced, and the payload of the spacecraft will naturally increase.

This is the initial strategic goal of the Venus development plan formulated by the Ministry of Aerospace, to achieve fuel replenishment on Venus.

In this way, the transportation capacity of the transport ship is increased in disguise, and then the industrial scale of the floating city is gradually expanded, so that the floating city can mass-produce raw materials on a large scale and realize the local manufacturing of floating modules.

As long as this strategic arrangement is completed, the development of Venus will become easier and easier as we go further.

Two days later, the carbon powder energy storage power generation module was successfully assembled in the floating city. The next task of Cheng Lin's team was to clean up the abandoned spacecraft in the orbit of Venus while waiting for the arrival of Zhurong 002.

That's right, it's cleaning up abandoned spacecraft.

In the orbit of Venus, there are abandoned spacecraft from Lao Maozi, NASA, and the Federation. Most of these spacecraft are probes and artificial satellites.

If these things are not cleaned up, they will become hidden dangers sooner or later.

As time goes by, these wastes will gradually disintegrate into small fragments, making the danger even greater.

The Federation's foundation on Venus is currently relatively weak. If the unmanned spacecraft is damaged, it can still afford it.

But if a manned spacecraft or a large transport ship is damaged, the loss will be huge, and even casualties may occur.

At present, the Federation has maintained zero casualties in the development process of the aerospace field. This kind of risk can be avoided in advance. There is no need to wait until it happens and then make up for it.

The three of them, Cheng Lin, divided the work and worked together. He remotely operated the Pioneer spacecraft to clean up abandoned spacecraft in the orbit of Venus.

Wang Yunhai is responsible for monitoring the floating city, while Qin Tianci is responsible for maintaining contact with the Blue Star Remote Control Center.

The waiting time is boring and long.

Life in space is not as thrilling as described in science fiction movies. Under the constraints of many rigid regulations, it is impossible for astronauts to operate in violation of regulations.
