In Mendeleev City on the back of the moon, three Gonggong-class spacecraft in the 106 Space Shipyard completed the final outfitting work.

Looking down from the sky above the back of the moon, you can see three ring-shaped buildings. In the middle of the ring-shaped buildings is a "building".

In fact, these are the three Gonggong-class spacecraft. The shipyard is semi-open-air construction, and a large part of it is deep underground.

After all, the overall design of Gonggong-level is a spindle in the middle, and then a rotating wheel compartment is added, which looks like a grinding wheel.

The completed Gonggong-class spacecraft is loaded with a full load of 87,623 tons, equipped with 15 single-unit nuclear fusion generator sets with a total output power of 750,000 megawatts.

In terms of power, a new plasma engine is adopted.

There are also emergency backup N-fuel rocket engines, mainly to ensure fast braking and rapid acceleration.

After all, the disadvantage of plasma engines is that they start very slowly and require continuous acceleration to increase the speed of the spacecraft to the expected speed.

Therefore, plasma engines are relatively weak in terms of fast variable speed.

If you encounter situations such as sudden acceleration or sudden deceleration, the plasma engine will not be able to handle it.

In this case, it is very important to quickly provide power to the N-fuel rocket engine.

In terms of the internal supporting facilities of Gonggong-class spacecraft, on the one hand, it is the simultaneous gravity living area of ​​the rotating wheel compartment. The rotating wheel compartment has not been fully deployed yet, and it is mainly still in a shipyard and is not very convenient to deploy.

After the Gonggong-level is launched, the rotating wheel compartment can be expanded, and it can be turned into a rotating wheel with a radius of 7.6 kilometers.

The inner part of the rotating wheel cabin is four areas, two living areas, one planting area and one material storage area.

Inside the rotating wheel compartment, the power system is three independent nuclear fusion generator sets, with a power generation power of 150,000 megawatts, accounting for 20% of the total output power of the entire spacecraft's power system.

The rotating wheel compartment is connected by a rotating arm and a spindle, and the traffic between the two is carried out through an elevator set on the rotating arm.

In fact, the proportion of the rotating wheel bay in the total mass of the spacecraft is not high, only about 23,000 tons, and the spindle occupies the large end of the spacecraft, with a total of about 64,000 tons.

Of course, there are many other quality in it, which is used on fuel, consumables, and water.

Gonggong-grade spacecraft has a complete industrial production system. From raw materials and finished products, as long as there are sufficient raw materials, they can achieve self-sufficiency.

It is equipped with 18 industrial modules including "mineral refining module", "electric field synthesis module", "nanobot processing module", "3D printing module", and "artificial food synthesis module".

Even carbon-based chips can be produced in small batches through nanorobot processing modules. On the entire spacecraft, except for the nuclear fuel that cannot be self-sufficient, everything else can be self-updated through internal industrial modules.

This is basically a small city with all kinds of internal organs. The technology above can be said to be the master of the Federation's technology in recent years.

If you can travel through time and space, the technology on this spacecraft can allow a force to quickly achieve technological breakthroughs.

After the installation was completed, the driver drove the Gonggong-level and prepared to take off to the 450,000-kilometer orbital area of ​​Blue Star.

This orbital area is relatively empty, which is very suitable for the test of this large spacecraft.

In order to allow the Gonggong Class to take off smoothly, the shipyard also specially equipped a batch of external rocket boosters. Driven by the surging light red flames, one of the Gonggong Classes successfully took off.

In fact, plug-in rocket boosters are commonly used auxiliary equipment for this large spacecraft.

Even when the Gonggong-class spacecraft officially heads to the outer layer of the solar system after completing its trial voyage, the Ministry of Aerospace will prepare a batch of large external rocket boosters for it on the moon.

Through these rocket boosters, the flight speed of the Gonggong-class is increased to more than 15 kilometers per second at one time, and then the plasma engine is relayed.

When the spacecraft arrives at the asteroid belt, it will collect resources in the asteroid belt to replenish fuel and material consumption along the way.

For the Gonggong-class spacecraft itself, its internal payload needs to be used in key places, and the rocket booster can provide an auxiliary effect.

The trial work begins.

After the launch, the Gonggong-level quickly unfolded the rotating wheel compartment, and the rotating wheel compartment began to rotate slowly. When the rotation speed reaches the set value, obvious centrifugal force began to be generated inside the rotating wheel compartment at this time.

In this centrifugal force, like gravity, it "sucks" the items inside the rotating wheel compartment on the floor.

The astronauts in charge of the test, Dong Feng and Mu Haodong, entered the living area of ​​the rotating wheel cabin through the elevator from the spindle cabin.

As the elevator approached the rotating wheel compartment, the two felt a force pulling their bodies.

As the elevator got closer and closer to the rotating wheel compartment, the force became more and more obvious. Until the elevator compartment arrived at the living area, Dong Feng and Mu Haodong seemed to have returned to Blue Star.

This obvious mesophical gravity is completely different from the pressure of the internal pressure servo, which is a relatively macroscopic force field.

The two of them adapted for a while before stepping out of the elevator cabin.

The living area is not all for daily use. The living area - Area A is actually a working area, and it includes cockpit, kitchen cabin, sanitary cabin, medical cabin, etc.

The living area - Area B is a hibernation cabin, a sleeping cabin and a entertainment cabin.

Dong Feng and Mu Haodong tested various facilities. During use, the usage status was actually similar to Blue Star.

However, just in case, all kinds of items inside have special usage specifications, such as drinking water and other liquids, which do not affect direct exposure to the cabin, but should be stored in a special bottle and can container.

The reason for such strict restrictions is mainly because of the concern that if the rotating wheel compartment stops rotating, the centrifugal force will disappear.

In this case, the microgravity state will be restored to the inside of the rotating wheel compartment.

In microgravity states and in blue star gravity states, many items appear in different states, and this state may cause fatal danger.

For example, liquid state, in a weightless state, will become small water droplets floating everywhere, which can easily be breathed by astronauts and inhaled into the airway, causing the risk of suffocation.

There are also various floating small objects, such as a ballpoint pen and a nail clipper. When it is weightless, it is easy to float around everywhere. This will not only cause trouble in finding things, but also cause some potential dangers.

Especially in the rotating wheel compartment with gravity, astronauts suddenly enter a weightless state after getting used to this gravity compartmental environment and will subconsciously not be able to react.

Therefore, the internal management of the rotating wheel compartment is even necessary to be stricter in weightless compartment, and all possible potential dangers are taken into account.

The Gonggong-level working area needs to be in the outer layer of the solar system for a long time and away from the federal government. If there is a serious accident, you can only rely on the astronauts above to save themselves.

Be prepared imprudently. If something goes wrong, the astronauts above may have to pay the price of their lives.

The test work is in full swing.
