36,000 kilometers away from the equatorial ground.

Geosynchronous orbit.

A pure white spacecraft stagnated in a dark sky.

Looking down, there is a planet with sky blue dotted with large white clouds - the earth, and behind it is a dark deep space.

Quiet, dead silent.

There is no vitality. Compared with the earth, this is the forbidden zone of life.

Tianshu cockpit.

Fifteen astronauts are each busy with their work.

The captain of the Tianshu transport spacecraft was a young R-type clone. It can be seen from his behavior that the captain of the Tianshu is much more stable than the young man of his age.

"Report to the General Control Center, this is Tianshu No.!"

"Please say Tianshu!"

About a second passed.

In the holographic projection screen in front of me, a young figure appeared in front of the captain Tianshu.

"The first phase of Tianshu has been completed, and the performance indicators of the hull are normal. Currently, the remaining energy is 93.74%. The first phase of Tianshu has been completed, and the performance indicators of the hull are normal. Currently, the remaining energy is 93.74%. Please implement the second phase of the hull!"

Captain Tianshu calmly reported on the holographic projection of Luzhou.

Their crew members came to the geosynchronous orbit. In addition to testing the performance of Tianshu, they also had an important task, which was to build a small part of the building materials it carried for the construction of the spaceport.

certainly.

Building a complete spaceport is a huge project, and it is definitely not something that can be done by just one or two transportation.

However, as long as the performance indicators tested by Tianshu meet expectations, Civilization Science City will definitely manufacture such a space transport ship on a large scale.

Although the 100,000-ton spacecraft is difficult to manufacture with the industrial strength of the Civilized Science City, the intelligent unmanned factory cluster in the second zone is fully fired.

It’s still no big problem to build more than a dozen ships a year.

In this way, the speed of building a spaceport is faster.

It is expected that this spaceport dedicated to mooring space transport ships will be completed before the end of next year.

He paused for a moment.

The command from the Ground Control Center was sent over: "Tianshu, the second phase of tasks are allowed to be executed, repeated, and the second phase of tasks are allowed to be executed. In addition, I wish you all peace and we are waiting for you on earth!"

Hearing this.

The excited expression on the captain of the Tianshu face flashed, and he immediately replied: "The Tianshu has received it, guaranteed to complete the mission and wait for our good news!"

After saying that, he cut off the communication.

You should know that in outer space, communication resources are a very luxurious resource, especially communication means such as holographic projection, which consumes communication resources even more amazing.

Fortunately, Tianshu is not far from the earth now. If it was on Mars at this moment, it would probably not use the luxurious method of holographic projection communication, but instead chooses simple call communication.

If the flight speed of spacecraft is the first restrictive factor in the exploration of space, communication technology is the second restrictive factor.

Tianshu uses a nuclear fusion engine as the power source and a unique electric propulsion system.

In theory, its navigation speed can accelerate to a maximum of one ten thousandth of light in a gravity-free environment, which is nearly twice the speed of the third universe.

From this perspective, Tianshu can escape the gravity of stars and thus leave the solar system.

But it is impossible to actually operate.

At least it is impossible to carry a man to leave the solar system. The reason is very simple, humans do not have that long life span.

The Tianshu can't carry supplies that humans consume tens of thousands of years.

If Tianshu is regarded as an unmanned spacecraft and flew out of the solar system, just like the Voyager, it is possible that it will leave the solar system in the next few thousand years or tens of thousands of years.

But Lu Chen obviously wouldn't do this.

If there are alien life in the universe, wouldn’t he tell others that there are life planets in the solar system, so come and ravage me quickly?

It would be easy to say if the civilization level of alien life is not high. If the civilization level is higher than that of the earth, wouldn’t he become a sinner to all mankind?

Because you can't tell whether alien civilizations are good or malicious.

As for Lu Chen himself, he believed that if a civilization could develop, its civilization would definitely have a cruel nature.

Take humans as an example.

If humans can reach the position of the overlord of the earth, how many species have they walked out?

It would be fine if the level of alien civilizations is behind. If the level of civilization is higher than that of the earth, and it just needs the living environment of the earth.

Lu Chen believes that humans are likely to be genocidalized by aliens like the natives during the Great Discovery period.

Apart from this problem.

There is another problem with Tianshu that wants to leave the solar system, that is, communication is inconvenient.

The communication speed of electromagnetic waves in the earth is indeed fast enough, but it is too slow at the scale of the universe.

Not to mention leaving the Tianyang System.

Only when the distance between Earth and Mars communicates is delayed by more than ten minutes.

If you cannot communicate with the command center in real time, the spacecraft drifts in a dark space, just like a small boat in the sea. Whether it is the psychology of the spacecraft crew or the actual exploration of space, it is a huge test.

Exploring space in this situation is a complete bet on the lives of the crew.

Not reliable than adventurers during the Great Time of Discovery.

At least at that time, the ships that navigated the sea were much more advanced than the spacecraft that explored the space now.

......

Get the command from the ground control center.

The captain Tianshu and his crew members were instantly motivated.

Their mission to outer space this time was only two.

The first is to check the various properties of Tianshu, and the second is to put down the materials used to manufacture space and the octopus-type construction robot in the geosynchronous orbit.

At this point, their mission was successfully completed.

As for the second phase of the mission he mentioned in the report, it should actually be considered the next new mission of Tianshu.

That is to explore the f-1704 asteroid.

According to the space telescope monitored by Ling, this f-1704 asteroid is a mineral planet about 4 million kilometers away from Earth.

Moreover, its orbit is constantly approaching the earth, and finally it gradually drifts away from the earth when it reaches 3.415 million kilometers.

According to preliminary observations, there are a large number of metal minerals on this asteroid.

It can fully meet the consumption of most of the mineral materials for space city construction.

According to the preliminary plan of Linghe Academy of Civilized Sciences.

The innermost annular structure of a space city requires about 1 billion tons of metal materials and other materials.

Although compared with the 420 tons of the International Space Station, 1 billion tons looks like it is many times larger.
