Humanity is missing, luckily I have billions of clones.

Chapter 93 Maiden Voyage!

At this moment, because Li Qingsong has made it clear that he will leave Luoshen and head to the inner solar system after fully mastering the secondary pressurization propulsion technology, he does not have the need to build too many spacecraft with existing technology levels at this stage. So, starting more than ten years ago, all the shipbuilding factories on Luoshen that had been roaring day and night were closed.

But now, under Li Qingsong's command, they are reborn again.

Raw materials began arriving by train once again, and a large number of clones were converging here. After the power grid was overhauled, a surge of electricity was once again delivered.

As a result, a large number of parts were once again produced from these factories.

All these parts were transported to the orbit around Rosen, where assembly began.

The most important of these is the secondary pressurized thruster with a total mass of more than 5000 tons.

A complete secondary booster consists of three modules: a nuclear fission reactor module, an internal combustion engine module, and an electromagnetic control module.

These three modules assembled together form a complete and currently most advanced thruster.

It cannot be disassembled because its processing requirements are too high and can only be produced on the ground.

At this moment, the cargo spacecraft needs to be assembled in space.

There was no other way, so Li Qingsong had to develop a special method for transporting large and heavy cargo, and used 40 dedicated aerospace spacecraft to lift it up.

The total volume of this thruster reaches more than 50 cubic meters, with a length of 25 meters, a width of 10 meters and a height of meters.

It has over 1000 connection holes welded on it and 1000 high-strength cables extending from it.

Every 25 cables converge into one and eventually extend to a dual-purpose aerospace spacecraft. A total of 40 spacecraft are used to lift this behemoth through these 1000 cables.

The chemical fuel in the forty ambiance-type spacecrafts burned explosively and spewed out violently, pushing the propulsion power to the extreme. With precise coordination, they jointly increased the speed of this engine weighing more than 5000 tons.

For a moment, the lifting site was covered in dust, and countless gases vaporized instantly, as if a thick fog appeared out of thin air.

But even though the propulsion power of these 40 aerospace spacecraft has been increased to the extreme, this huge engine is still only slowly increasing its speed, leisurely.

There's no way around it, it's just too heavy. Even if there were 40 spacecraft, the mass of each one that needed to be accelerated would be over 130 tons.

This has nothing to do with the gravitational field of Roselle, but only with the object's own mass. And mass is constant, no matter what gravitational field it is in.

Spewing out a large amount of fuel, the engine slowly rose diagonally upwards, increasing its altitude and speed.

Finally, after flying around Rosen three times, the engine's speed was finally increased to 950 meters per second.

At this time, it can finally fly around Luoshen on its own without the need for additional pulling force.

After one engine was delivered, the second and the third followed. In the end, a total of 50 engines were delivered into space.

Along with it came a large number of spacecraft parts.

In this vast space, the steel plates of the spacecraft's hull began to be welded, the frame began to be built, the engine began to be fixed, the internal wiring began to be connected, and the pipelines began to be connected...

Finally, after spending several months, Li Qingsong built his first spacecraft using secondary pressurization propulsion!

This is undoubtedly a behemoth.

It is 330 meters long, 50 meters wide at its widest point, and 20 meters high at its highest point. Its total volume is 7.3 cubic meters, and its total empty mass is 1.6 tons!

When fully loaded, the maximum total mass can reach 8 tons!

Goods from the surface of Luoshen and in space, ready to be shipped to Enemy Star, gathered into this huge cargo ship like rivers flowing into the sea, filling every one of its cargo holds.

Next, Li Qingsong’s long-awaited maiden voyage finally began.

The fission reactor power began to increase, producing more energy in addition to powering the spacecraft itself;
The internal combustion engine starts to start, and the more than 2000 tons of liquid oxygen and methane inside it begin to burn, generating high-temperature and high-pressure gas, which is sent into the secondary compression chamber.

Energy from the fission reactor rapidly heats these gases, turning them into plasma due to the extremely high temperature.

Before these plasmas cause harm to the physical chamber, the electromagnetic confinement device starts working, confining these high-temperature and high-pressure gases within a smaller volume, preventing them from coming into contact with any physical objects.

When the pressure rises to a certain level, the electromagnetic restraint device opens a channel.

Then, like a dam collapsing, this extremely high-pressure plasma was unstoppable and rushed out along this channel at a speed of up to 30 kilometers per second.

Under this huge reverse thrust, the huge hull of the cargo spacecraft with a total mass of 8 tons began to accelerate slowly, and finally broke free from the gravitational field of Luoshen and flew towards the enemy star more than 4000 million kilometers away.

During this process, the acceleration never stopped, even when the speed reached 12 kilometers per second.

In the past, when the speed reached 12 kilometers per second, the cargo ship would enter an inertial navigation state and no longer accelerate.

It's not that they can't reach higher speeds.

In this weightless space, as long as you continue to accelerate, your speed will become faster and faster.

The most critical problem is that there is not enough fuel.

If you keep accelerating, you can indeed go faster, but when you reach your destination, you don’t have enough fuel, so how do you slow down?
12 kilometers per second is the product of a helpless compromise that combines the amount of fuel carried, transportation speed, and timeliness.

But at this moment, the speed of the cargo ship was increasing.

20 kilometers per second, 30 kilometers per second...

It didn't stop until it reached 60 kilometers per second!
Its acceleration efficiency is not higher than that of other cargo ships, but the duration of acceleration is several times longer.

Previous cargo ships could not accelerate to such a speed even if they used up all their fuel.

And now, even if it accelerates to a high speed of 60 kilometers per second, the chemical fuel carried inside this cargo ship has only consumed 800 tons!

Not even half.

Its comprehensive fuel utilization rate is six times that of ordinary chemical-propelled cargo ships!
At this unprecedented speed, it took only 8 days to reach the vicinity of the enemy planet.

After taking a day to slow down and consuming another 800 tons of fuel, it finally docked in the port of Enemy Star.

It took a total of nine days to complete a journey that would take an ordinary spacecraft more than a month.

And consumes less fuel!
