Homo sapiens.

After reporting the relevant situation.

Dr. Mikoyan, the head of the Space Division, came to the base on the back of the moon through a synchronous robot.

At this time inside the spaceship shipyard of the base.

A spacecraft designed for electromagnetic acceleration has completed its final checks.

This spacecraft is a variant of the Tinder class, called the Magnetic-class spacecraft, with a total weight of 7600 tons.

The base chief accompanied Mikoyan to the side of the spaceship.

"Minister, we have placed the test monkey and anthropomorphic body in the cockpit of the spaceship, ready for the first test at any time." The base chief said eagerly.

Mikoyan did not procrastinate, but let them prepare for the launch. At the same time, the staff in charge of recording quickly took pictures of this scene as a souvenir. This is one of the development history of Homo sapiens.

Moreover, Li Qingye is currently researching the technology of the six-claw civilization, and has no time to come and investigate, so Mi Gaoyang naturally wants to record this scene.

Soon the base chief was ordered to prepare for launch.

Under the drag of the tractor, the magnetic-class spaceship slowly moved towards a circular orbit not far away.

In addition to the tractor, there are various auxiliary and fixed equipment to ensure that the 7600-ton magnetic-class spacecraft reaches the circular orbit safely.

After half an hour of slow movement, the magnetic-level 0001 spacecraft was finally in place.

With the closure of the magnetic field binding layer on the side wall of the circular orbit, the launch finally entered the countdown.

"Start to speed up!" The base chief ordered very calmly.

"Received." As the commander pressed the accelerator switch.

The magnetic-class spaceship, which was still motionless just now, slowly moved forward.

The speed increased very slowly. Even with the magnetic levitation track, the speed of the spacecraft still did not soar.

This is electromagnetic acceleration. If it accelerates suddenly, the terrifying acceleration is enough to instantly kill many large carbon-based creatures on the spacecraft.

The 300-kilometer-long circular track, supported by the surging electric energy of the nuclear power plant, pushes the magnetic-class spacecraft to accelerate a little bit.

After going around in a circle.

The speed of the spacecraft has increased to about 1000 kilometers per hour.

Then it breaks through Mach [-], Mach [-]...

Until the 12th lap, the speed of the spacecraft has soared to an extremely terrifying 15 kilometers per second.

"Access to the No. 2 tower track."

"Access successful..."

In less than ten seconds, the magnetic-class spacecraft flew towards Jupiter along the high tower orbit, with a speed of 15.3 kilometers per second.

And because there is no barrier of the atmosphere, the speed of the magnetic-class spacecraft does not slow down but maintains inertia, flying in the direction of Jupiter.

But soon, the back of the magnetic-class spacecraft will spit out light yellow plasma. Obviously, the autopilot system of the spacecraft has activated the plasma thruster.

According to this speed, the speed of this spacecraft will soon be increased to 35 kilometers per second.

This is the first stage mark for human beings to enter the universe.

Chapter 615 Mining

Due to the very fast initial speed, the speed of the magnetic-level 001 spacecraft soon increased to 35 kilometers per second.

It will take about 250 to 380 days to go to Jupiter at this speed.

At present, Jupiter is about 7.6 million kilometers away from the earth. According to the moving direction of the two sides facing each other, it will arrive at Jupiter in about 277 days.

If it is a fire-class spacecraft that uses nuclear explosion propulsion, this time only takes 20 to 30 days.

It's a pity that nuclear explosion propulsion cannot be applied to magnetic-class spacecraft.

However, instead of going to Jupiter, the destination of the second magnetic-class spacecraft is Mars. With a limit speed of 35 kilometers per second, the spacecraft will take 25 to 83 days to arrive.

The third Magneto-class ship is headed for Venus.

All three test magnetic stages were launched.

And the synchronous robot on the spacecraft is checking the situation of those monkeys and anthropomorphic humans.

Judging from the current feedback information, the conditions of these experimental monkeys and anthropomorphic humans are not bad, and there are no accidents in some of the experimental bodies in the cryogenic chamber.

After all, when Homo sapiens established the Venus Cloud Palace base, it sent [-] employees to Venus. In terms of human cryogenic technology, Homo sapiens' technical level is not bad.

The purpose of testing the magnetic-class spacecraft this time is to eliminate some of the manned types of fire-class spacecraft. The speed of these spacecraft is too low to be conducive to development.

After all, at the Venus Cloud Palace base, many employees have already adapted to the gravity of Venus, and no major problems were found during the relevant physical examinations.

As the space colonization department that has just taken over Venus, it is natural to hope that more employees can be sent from Earth to Venus.

The speed of the old-fashioned manned spacecraft is obviously lower.

……

Venus.

Yungong Base.

This floating island floating above the atmosphere has now expanded to an area of ​​1.5 square kilometers.

As Wu Feng, who has just been in charge of the Space Expansion Department, he already has a preliminary understanding of the situation on Venus.

Due to the consideration of the existence of Venus' atmospheric ecosphere and underground ecosphere, the development of Venus in the future will focus on floating islands and a part of the surface area.

He is currently investigating a new project.

Inside the Yungong Shipyard.

Construction work has been completed on a huge hemispherical facility.

The hemispherical device in front of me has a radius of 500 meters.

"Minister, this is the integrated base module we designed and built." Designer Renault patted the outer wall of the hemisphere.

Wu Feng asked with some concern: "Designer Renault, can this thing withstand the high pressure, high temperature and corrosion on the surface of Venus?"

"Don't worry! Minister, we have used a high-temperature-resistant composite ceramic shell, plus an internal super-strong alloy layer, this thing can last at least 50 years on the surface of Venus."

Wu Feng looked at the hemisphere in front of him, thinking about the next arrangement in his heart.

This integrated base module is prepared for mining.

Its characteristic is that it can be hoisted by an airship and then placed in a desired position. After the mining is over, the mining base can be hoisted again and placed in a new mining point.

This is also no way.

If this method is not used, the minerals on the surface of Venus cannot be mined on a large scale.

As the person in charge of the Department of Cosmic Expansion, Wu Feng knew from the moment he took office that the bottleneck facing the Venus colony lies in the self-sufficiency of minerals.

The reason why bases such as Mars, the moon, and Callisto are built very quickly is that the local mineral resources can be self-sufficient, and there is no need to transport various raw materials from the earth.

To develop a planet, the premise is to achieve the self-sufficiency of the colony, so that it can develop steadily.

If the earth needs to transport basic materials all day long, it will not be a matter of opening up living space, but a heavy burden.

It was precisely because Wu Feng realized this that he cared so much about this integrated mining base.

Now Homo sapiens does not lack oxygen, carbon, sulfur, hydrogen and nitrogen on Venus, but lacks metal minerals. Although carbon materials can replace a large part of metal materials to a certain extent, some materials must use metal materials.

For example, cables, gold-based thermoelectric materials, and the skeleton of floating islands all use metal materials.

In recent years, the Earth Headquarters has sent a total of 47 tons of metal materials to the Venus colony, including 283 tons of gold and 1773 tons of silver.

This kind of reverse blood transfusion has made the company's management very entangled.

Now Wu Feng's first task is to solve the problem of mineral self-sufficiency in the Venus colony.

He ordered Renault: "Start the test!"

"OK."

This hemispherical mining base with a radius of 500 meters, under the control of the staff, slowly opened the hatch at the bottom, and then lowered it down little by little through the cables.

After half an hour.

The mining base was placed on the surface below the Cloud Palace base.

Then there is a huge engineering airship, which connects cables to the mining base. As the gas in the vacuum sphere inside the airship is pumped out, the buoyancy of the airship climbs rapidly.

This airship with a total volume of 50 billion cubic meters has a total buoyancy of more than 200 million tons on the surface of Venus.

The interior of the mining base is empty, with a total weight of only 36 tons. The airship lifted the mining base easily.

Soon the mining base was hoisted onto a pyrite mine.

According to geological exploration data, this pyrite is not only exposed on the surface, but also has an average mineral grade of about 38% to 44%, and the total reserves are about 8.5 million tons.

In addition, the pyrite also contains a part of nickel and copper.

Complete with the mining base being placed.

More than a dozen players on Earth are arranged to work here through synchronous robots.

Of course, in addition to the players on Earth, the Yungong base also sent several employees to manage the mining base through synchronous robots.

The bottom of the mining base quickly protruded the drill bit, and after drilling a mine with a radius of 5 meters, casings were used to ensure that the mine could be separated from the dense atmosphere on the surface.

Miner Li Le turned on the mining equipment, and the pyrite in the mine was crushed and sucked into the mining base.

In the heat insulation layer of the mining base, a thermal cycle pipeline is being arranged to generate electricity using the temperature of 400-500 degrees Celsius on the surface of Venus.

A steady stream of electricity directly separates crude steel, crude sulfur, crude copper and crude nickel by means of pure oxygen electric furnace steelmaking.

In less than a week, 24 tons of steel were extracted from the mining base, as well as a large amount of sulfur, copper, nickel and silicon.

The packed steel was hoisted into the Yungong base by the engineering airship.

Wu Feng saw that the test of the mining base was so smooth, and immediately ordered to use these raw materials, plus some metal materials transported from the earth, to build 10 mining bases.

As long as the scale of the mining base continues to expand, the Venus colony will soon be able to get rid of the material dependence on the earth.

This means that the size of a Venusian colony can quickly snowball.

It will not be too difficult to cover the floating island module with the atmosphere of Venus within 10 years.

If the previous plan is followed, it will take at least 50 years for Homo Sapiens to use floating islands to cover the atmosphere of Venus.

Now many raw materials can be self-sufficient, which means that this time will be greatly reduced.

But Wu Feng also encountered another problem, which was the shortage of manpower.

The current 2000 earth immigrant employees in the Yungong base, plus the 1.3 people who work on Venus through synchronous robots, are obviously not enough.

He hastened to send letters to various departments on the earth, requesting to increase the scale of immigration.

Chapter 616 Interstellar Immigration

In order to facilitate the management of the Venus colony, Wu Feng went to Venus in January of the 6th year of Xinghe on the magnetic-class 005 spaceship that has been verified by technology.

He was accompanied by 300 interstellar immigrants.

This is the third batch of immigrants. From now on, the earth will immigrate at least 1200 people to the Venus colony every month.

In the freezer compartment of the magnetic-class spacecraft, Wu Feng and others are in a frozen state, even though the current voyage from Earth to Venus is slightly closer than Mars.

If Venus is the closest to Earth, a magnetic-class spacecraft can reach Venus from Earth in 20 days.

When transporting materials to Venus on a large scale before, the time period between Venus and the Earth was specially selected, saving 85% of the voyage and fuel.

However, this kind of recent time period can only be encountered once every 580 days on average.

After 57 days.

Wu Feng and his party were awakened from the cryogenic hibernation cabin.

He came to the space station in the synchronous orbit of Venus.

From the Venus synchronous orbit space station, you can see that there is a clear "white cloud" in the atmosphere of Venus, which is the Yungong base.

Thanks to the continuous service of each mining base, the scale of the Yungong base has been expanded again, reaching 2.8 square kilometers.

A group of interstellar immigrants who just woke up also looked at Venus very curiously.
