In early August 2018, the design work of the floating module was initially completed, and a test version was prepared to be built on the Blue Star ground to verify the technology.

The location for building the floating module is chosen in the central Pacific Ocean, which has a vast sea surface and a relatively stable climate.

In Kiribati, near Bell Island, I found a deserted island as an experimental base.

After all, there are no densely populated areas in the central Pacific. Even if the floating module falls down during the experiment, it will not cause serious casualties.

The steady progress of the floating module project.

Preparations have also begun, such as carbon refining factories, carbon material processing plants, vacuum cavity shell manufacturing plants, solar panels, toner energy storage power plants, etc.

With the abundant carbon dioxide in Venus' atmosphere, the self-sufficiency of raw materials can be basically achieved.

Time flies by.

October 15th.

The Forward 003 spacecraft, which had sailed for 128 days, finally arrived at Venus's low-Earth orbit. After successfully entering orbit, it flew around Venus in an equatorial plane orbit about 750 kilometers from Venus' surface.

The Forward 003 spacecraft is an unmanned transport ship, carrying 480 tons of materials, mainly artificial satellites, small airship detectors, and ground detectors.

The Ministry of Aerospace is ready to launch various satellites this time and no longer ignores Venus as before.

Since Venus does not have a super protective magnetic field like Blue Star, artificial satellites arranged in Venus' orbit must be prepared to defend against solar wind.

After all, Venus does not have a super protective magnetic field, and it is relatively close to the solar system. It has suffered many and strong solar storms. Many artificial satellites have been killed by solar storms before.

The 12 communication satellites that have been arranged are implemented, including 4 Venus synchronous orbit communication satellites and 8 Venus' low-Earth orbit.

These satellite communication satellites, plus five communication satellites that have previously served on Venus, form a satellite communication network of Venus.

Next is Lagrangian point L1, located between Venus and the Sun, where two solar observation satellites will be arranged.

Then there are climate remote sensing satellites, geological remote sensing satellites, laser ranging satellites, etc.

After the arrangement of these satellites, the Ministry of Aerospace initially completed the construction of Venus satellite system.

At the Blue Star’s ground remote control center, the Venus Exploration Bureau is organizing a large number of staff to prepare to go deep into the Venus.

"Flying Whale One begins to launch."

As the staff pressed the confirm button, an electric wave was transmitted from the Blue Star ground remote control center to the Blue Star's low-Earth orbit communication satellite, followed by the communication satellite relay in the Blue Star's synchronous orbit and was transmitted to Venus.

The radio waves spanned tens of millions of kilometers and arrived at the Venus synchronous orbit communication satellite, and were finally received by the Forward 003 spacecraft.

A rocket ejected from one side of the forward 003 spacecraft, and the light red flame of N30 fuel pushed the rocket into the atmosphere of Venus.

15 minutes later, the Rocket braked near an altitude of 75 kilometers.

The middle of the rocket bounced open, the 16 vacuum cavity unfolded and the skeletons were fixed, and then some of the air inside the vacuum cavity was extracted.

As the vacuum cavity forms, buoyancy allows the rocket to float at an altitude of 75 kilometers, which is the lower part of the middle and middle atmosphere of Venus' atmosphere.

Although it is not a troposphere, the airflow here is very fast, reaching as fast as 100±10m/s per second, which is stronger than the 17th level wind on the Blue Star ground.

However, as the height of Flying Whale One gradually decreases, the wind speed gradually decreases. In fact, this is the characteristic of Venus' atmosphere. The lower the airflow movement speed will become slower and slower.

Near the surface of Venus, the average airflow movement speed is only 0.3 to 1m/s, which is much weaker than the surface of Blue Star.

However, the slow movement of the airflow does not mean that people and animals are harmless.

Because the gas concentration is very high, the high air pressure formed causes the air flow on the surface of Venus to have a fluid motion state similar to that of liquid.

Flying Whale One, the altitude drops to around 60 kilometers, and the wind speed drops further, and it remains at an average of about 50 to 60 meters per second, with occasional strong winds of 80 meters per second.

The temperature detector shows that the temperature at this time is minus 10 degrees Celsius, and the air pressure is 0.2357 standard atmospheric pressure.

According to this temperature and pressure, as well as the airflow and wind speed, it may not be suitable as a stable altitude for floating cities.

The temperature has nothing to do with it. The key is that the air pressure is too low. In terms of design standards for floating cities, the air pressure at this location needs to be maintained above 0.4 standard atmospheric pressure.

In addition, the airflow speed is too fast. After all, the level 17 wind of Blue Star is only 56.61 meters per second.

The 60-kilometer altitude area of ​​Venus' atmosphere has an average annual wind speed of 50 to 60 meters per second, which is equivalent to daily level 17 winds. It is a huge test for the posture control of floating cities.

Flying Whale One continued to descend.

After a while, we arrived near an altitude of 55 kilometers.

At this time, the data of the detection instrument shows that the temperature is 27 degrees Celsius, the air pressure is 0.5314 standard atmospheric pressure, the average wind speed is 40-50 meters per second, and the extreme wind speed is 75 meters per second.

The altitude continues to drop, reaching an area with an altitude of 50 kilometers.

At this time, the data of the detection instrument shows that the temperature is 75 degrees Celsius, the air pressure is 1.066 standard atmospheric pressure, the average wind speed is 30-40 meters per second, and the extreme wind speed is 60 meters per second.

Then there was an altitude of 45 kilometers, and the temperature here further increased to 110 degrees Celsius; the air pressure was 1.979 standard atmospheric pressure; the average wind speed was 20-30 meters per second, and the extreme wind speed was 50 meters per second.

Venus Exploration Bureau tens of millions of kilometers away.

After obtaining first-hand data, several researchers recalculated the appropriate height of the floating city.

One of the small researchers pointed to the simulated image and said, "If you consider the stability, I think the height of 45 to 50 kilometers is more suitable."

"Indeed, we can easily solve the high temperature of 75 to 110 degrees Celsius, and the air pressure between 1 and 1.9 means that the effective load-bearing of floating cities can be increased by about 2 to 3.8 times."

"In addition, the average wind speed is very high for altitudes over 50 kilometers, and there are some extreme winds, which require frequent posture control and consume a lot of fuel."

With the sorting of these data, the layout height of the floating city was decided to be adjusted to an altitude of 47 to 48 kilometers, with the upper limit of 55 kilometers and the lower limit of 40 kilometers.

Due to the change in position, the effective load bearing of a single floating module has been increased from the previous planned 2400 tons to 4800 to 8500 tons.

In fact, due to the increase in the air pressure zone and the very high concentration of atmospheric gas, the floating city is arranged at a height of 47 to 48 kilometers, just like it is in the sea.

The lower the atmosphere of Venus, the more viscous the gas becomes, no less viscous than in the sea.

If it weren't for solar power generation, it could actually be arranged more.

On the other side.

Many research institutes serving floating city projects are also racking their brains to cooperate with projects and developing equipment that is adapted to local conditions.

For example, the miniaturization of nuclear fusion by China National Nuclear Corporation has increased the load-bearing capacity of a single floating module, and the current smallest nuclear fusion generator set can be set in the floating module.

In addition to China National Nuclear Corporation, the Suiren Group's power generation equipment research and development company has also come up with its own power generation plan, which is even more suitable for floating cities in Venus than nuclear fusion generator sets.
