Chapter 592 (1/2)

According to the design data, after modification again and again, the final confirmed tonnage of the spacecraft remained at 12000 tons.

After all, the place where the spacecraft is assembled is on the moon. Although the gravity of the moon is only one sixth of that of the earth, it still has gravity. Therefore, after the construction of the spacecraft is completed, it needs to be separated from the gravity of the moon.

With human civilization and current technology, it is already the greatest ability to send a spacecraft of more than 10000 tons from the moon into space. If the tonnage of the spacecraft continues to increase, with the current technology of human civilization, it is simply impossible to send it into space. Even if the moon has no atmospheric resistance, its gravity is only one sixth of that of the earth.

What's more, with the current technology of China, although it has the ability to build ships of 100000 tons or even larger, it has not built submarines of more than 10000 tons in terms of submarine construction, and the technology of this spaceship is based on submarines. Naturally, even if it is built with more than 10000 tons, there is already a great risk for China, Not to mention the bigger one.

In addition, there is another situation, that is, in the past, what Wang Bin wanted to build was a purely military spacecraft. After all, for today's human civilization, the most important thing is a military spacecraft. After all, the threat of alien civilization is at hand.

However, considering that the current technology is not mature enough, and compared with military spacecraft, there is another kind of spacecraft, which is more important for human civilization, that is, scientific research spacecraft.

Therefore, after high-level discussions between Wang Bin, Qin Lao and other officials, it was finally decided that the spacecraft in the military model could be built slowly first, but the scientific research-based space exploration and measurement ship should be built first.

After all, in the plan for the next few years, warm civilization will build a large-scale base on Mars, but now human civilization's understanding of Mars is very limited, or even no chance.

Therefore, before human civilization builds a Mars base, it must carry out large-scale exploration and understanding of Mars before construction.

If we don't use large-scale space research exploration and measurement ships, but use ordinary small spacecraft to explore Mars, according to the situation, it will take at least 20 or 30 years for human civilization to build Mars.

After all, the small space vehicle can carry only one or two kinds of equipment and instruments, and the function of the equipment is also very limited due to the limitation of the aircraft volume.

The large spacecraft is different. It can not only carry a large number of equipment and large equipment, but also a large number of scientists to study Mars on the spacecraft for a long time.

In addition, since human civilization wants to build defense facilities in the asteroid belt, it is natural to have a certain understanding of some basic data of the asteroid belt, such as magnetic field, celestial bodies and ambient temperature.

These require large space research ships to be competent.

It was for this reason that Wang Bin, their relevant departments of Tiangong science and technology and the relevant official departments finally confirmed the construction of the space scientific research and exploration survey ship after discussion.

”Mr. Wang! Our research ship was named Dijiang class according to multi-party negotiation, and the first ship was naturally named Dijiang according to convention.
