Homo sapiens

Bai Yulou and others are familiar with scientific research work.

At this time, in the industrial area of ​​​​Yungong Base, a "submarine" was undergoing final finishing work.

This is a specially built submarine, mainly to deal with the terrifying high temperature, high pressure, strong winds, and corrosive gases on the surface of Venus.

You must know that the air pressure on the surface of Venus can reach nearly a hundred times the standard Earth atmospheric pressure, the temperature remains at 400 to 500 degrees Celsius all year round, the wind speed is about 200 meters per second, and various corrosive gases are densely covered.

What is purgatory?

This is purgatory.

None of the small probes previously sent to the surface of Venus survived more than six months.

This time, the Yungong base plans to build a large submarine, which is 500 meters long and 60 meters in diameter. There are many vacuum carbon balls inside the submarine.

In order to withstand the extremely harsh environment on the surface of Venus, the submarine shell uses a composite ceramic layer and a high-temperature-resistant alloy layer, which can withstand temperatures of 5,500 degrees Celsius without melting. It can also withstand 500 standard atmospheric pressures and is also very corrosion-resistant.

In addition, a layer of gold-based thermoelectric material is added to the outer shell composite layer, which can continuously absorb the surrounding heat energy and continuously convert the thermal energy source into electrical energy.

Obviously this plan is adapted to local conditions and makes full use of the high temperature on the surface of Venus.

If the temperature of 400 to 500 degrees Celsius and the high-pressure air are not used, it will be a waste of resources.

After completing the final finishing work, five synchronized robots entered the cockpit and then completely sealed the hatch.

"Open the floodgates!"

"receive."

In the shipyard in the industrial area, the internal hatches were closed tightly, and then the door to the outside world slowly opened.

A large amount of carbon dioxide and other gases rushed into the dock of the shipyard, but since all the synchronized robots have been evacuated to safe areas, the remaining submarines do not have to worry.

Although synchronous robots do not need to breathe, the corrosive gases in Venus' atmosphere can still easily damage the robot's parts and sensors. The cost of these synchronous robots is not cheap, and unnecessary losses must be avoided as much as possible.

Inside the submarine cockpit.

Foucault, the controller behind the synchronized robot, as well as Ang Fujita, Huang Wei and others, immediately controlled the submarine to take off.

In fact, this is the same principle as an airship. At this time, the vacuum carbon ball of the submarine is still full of carbon dioxide. As the vacuum pump starts, the carbon dioxide concentration in the vacuum carbon ball gradually decreases, and the submarine floats little by little.

The propeller propelled the submarine out of the dock.

When the submarine flew out of the dock door and reached high altitude.

"Start inflating," Foucault ordered.

"Yes." Huang Wei nodded. He activated the carbon dioxide collector on the submarine shell and re-inhaled the carbon dioxide in the atmosphere into the vacuum carbon ball.

As the vacuum carbon balls are filled with carbon dioxide, the buoyancy of the submarine also decreases simultaneously. The decrease in buoyancy will naturally cause the submarine to descend.

In less than fifty minutes, the submarine dropped from an altitude of about 52 kilometers to an area less than 500 meters above the ground.

At this time, the violent winds on the surface of Venus and the terrifying atmospheric pressure made the submarine feel a lot of pressure. If it were not for the high-strength shell, such terrible pressure would be enough to crush ordinary detectors.

Red Purgatory.

Corrosive acid mist.

Extremely high pressure.

Hundred-meter strong wind.

A huge ship is fighting for passage here.

If there were intelligent creatures here, this scene would become a myth.

Unconsciously, the Homo sapiens company has reached a very powerful point, and various technologies are continuously expanding the living space of mankind.

Through a special observation periscope and a high-power searchlight, you can see the surface of Venus.

There are weathered landforms formed by magma rocks everywhere, which look a bit like the Yadan landform. The strong wind is mixed with fine stones and sand, which constantly beats the outer shell of the hull.

But this is not the goal.

Because this place has been explored once before, there is nothing worth studying.

Foucault looked at the holographic map, then adjusted his flight direction and flew towards the south pole of Venus.

The terrain on the surface of Venus is mainly flat land, with some basins and a large mountain range. On top of the mountain range is the highest peak in the solar system.

Over at the South Pole, several previously launched detectors malfunctioned and failed to reach the South Pole.

During the flight, the terrifying strong winds disturbed the submarine, forcing the submarine to use part of its power to correct its flight direction and avoid being deflected by the strong winds.

Fortunately, the surface of Venus is like a big furnace, and submarines can continuously obtain electrical energy through gold-based thermoelectric materials.

Looking at the flat surface, Foucault knew very well that it was not that the surface of Venus was born as an airport, but that it was ground into needles by the strong winds.

Those magma rock mountains formed by volcanic eruptions are difficult to resist the weathering and corrosion of strong winds and acid fog.

Suddenly the alarm system went off.

[alarm! There is a large-scale thermal reaction ahead of the monitoring, and a moderate volcanic eruption has occurred. Please avoid it in time...]

Foucault quickly adjusted his flight direction and bypassed the core area of ​​the volcanic eruption.

Magma activity on Venus is very frequent. Among the terrestrial planets in the solar system, the surface rock layers of Venus are the youngest.

This shows how frequent volcanic activity is on Venus.

Of course, there are pros and cons to volcanic activity.

On the one hand, volcanic activity will erupt a large amount of toxic and harmful gases and volcanic ash, and cause volcanic earthquakes.

On the other hand, volcanic eruptions will bring rare metals and heavy metals from the mantle to the surface, which can form rich mineral resources and also release a large amount of geothermal energy into the atmosphere.

Now the Yun Palace Base is preparing to mine Venus surface minerals to reduce its dependence on the Earth Headquarters.

According to data from the Venus Mineral Analysis Institute, there are currently 700 billion tons of pure iron, 5.3 billion tons of elemental copper, and a lot of gold, silver, rare earths, platinum, tungsten, etc. stored in the strata above 500 meters deep on the surface of Venus. .

Since the atmosphere is full of carbon dioxide, many of the metals in the magma erupted from volcanoes are in simple form, which is similar to the environment of the early Earth.

It’s just that Venus has not encountered the Great Oxidation Event caused by cyanobacteria, and coupled with hundreds of millions of years of continuous volcanic eruptions, the metals here have remained in a simple state for a long time.

This mineral is much better oxidized than the earth's metals and can be easily extracted.

Some of the precious metals and heavy metal materials used in the previous submarine construction process were transported bit by bit from the Earth, which is very detrimental to the development of Venus.

Therefore, the Yun Palace Base is very greedy for a lot of minerals on the surface of Venus.

Of course, there is nothing you can do if you are greedy.

After all, the surface of Venus is too harsh. It is obviously too difficult to build a metallurgical base on its surface. It is not that the technology does not allow it, but the cost is very high and the price/performance ratio is too low.

The Yungong Base is organizing manpower to study how to mine at low cost, so that the Yungong Base can get rid of its dependence on the earth for materials.

The submarine made twists and turns for two days and two nights amid strong winds and sandstorms, and finally arrived near the South Pole of Venus.

This is a relatively large basin. The submarine dropped some height and found that the wind speed here also dropped a lot.

The purpose of their coming here is to search for ancient geological relics and see if they can find out whether Venus was bombed by an asteroid or other changes.
