Homo sapiens.

Although the new aerospace engine of the Mendeleev base city on the moon has not yet reached the level envisioned.

But it is more than enough for use in the inner solar system.

After all, the service life of lithium carbon nanolayers is actually only a problem in a specific environment.

Navigating inside the solar system can completely increase the thickness of the lithium carbon nanolayer, so as to prolong the service life of the lithium carbon nanolayer.

Therefore, after 37 days of trouble-free operation of this engine, the Space Business Department, the Space Defense Department, the Space Colonization Department, and the Earth Defense Department have joined forces to replace the engines and propellers for all current spacecraft.

Since the moon belongs to the defense zone of the Ministry of Defense of the Earth, Maungu directly dispatched 5 space battleships and handed them over to Mendeleev Base City, allowing them to install new nuclear fusion engines and plasma thrusters on them.

For the Qinglong-class space battleship weighing 12 tons, only one "Carl 1B" is needed.

Carl 1B is a nuclear fusion power system specially used in the solar system. The lithium carbon nano-layer is three times thicker, which is enough to ensure the trouble-free operation of the nuclear fusion power system for 3 to 90 days.

The spaceship will also be equipped with a spare lithium carbon nanolayer, which can be quickly replaced at any time.

In addition, according to the simulation test, the spacecraft sailing in the inner solar system does not need to use a speed of 6000 kilometers per second at all. This speed is too cost-effective to use in the inner solar system.

According to the results of the simulation test, the limit speed of 200-1000 kilometers per second is the best limit speed of a spacecraft equipped with a nuclear fusion power system.

For example, from the earth to Venus, Mars, and Mercury, the speed of 200 kilometers per second is the most cost-effective, and the voyage only takes about 3 to 15 days.

Although the speed of 1000 kilometers per second can be used, the price/performance ratio of this speed is too low. The flight process is completely accelerating and decelerating. For a manned spacecraft, the continuous violent acceleration and deceleration will make the riding experience very bad.

The speeds to Jupiter, Saturn, Uranus, and Neptune are respectively 400 kilometers per second, 500 kilometers per second, 600 kilometers per second, and 700 kilometers per second.

To Pluto and the Kuiper belt, it is 800-1000 kilometers per second.

This is a limit value specially calculated based on the distance between the two planets.

Normally, these limit values ​​are constantly adjusted according to the distance between the two planets to ensure the most cost-effective voyage.

The spaceships sailing in the inner solar system, equipped with Carl 1B, will not run at full power. Under normal circumstances, only 2 to 4 nuclear fusions of Levi's rings will be turned on.

This can save fuel on the one hand, and on the other hand can extend the overall service life of the lithium carbon nanolayer of the power system.

In less than half a month, one of the Qinglong-class space battleships was upgraded.

This is the terrifying productivity of Homo sapiens. As long as the product design plan is determined, the transformation of the production line can be completed soon.

At present, the production line of the Karl-1B nuclear fusion power system in Mendeleev Base City on the Moon can produce 50 Karl-1Bs per month if it runs at full capacity.

After the Qinglong-class space battleship completed the upgrade of its power system, it was quickly pulled to the spaceport on the side of the base.

Considering the plasma thruster of the Karl 1B type, the plasma tail flame ejected by it is very terrifying, basically no different from a particle cannon.

Therefore, this improved version of the Qinglong class must pay attention to the direction of the nozzle of the propeller during take-off. If the nozzle is aimed at the equipment and facilities of the spaceport, it is very likely to cause unnecessary losses.

The management personnel in charge of the spaceport arranged a special inclined runway for the Qinglong class.

Captain Yin Siyong looked at the star chart.

At this time, the back of the moon is facing the orbit of Mars, and he immediately ordered: "Everyone is there, target Mars, and move forward at full speed!"

"receive."

The two Levi's rings in the powertrain quickly enter fusion operation.

When the soldier in charge of controlling the thruster pressed the start button, the thruster began to spit out aluminum ions that were ionized into plasma.

The aluminum ions accelerated to 15% of the speed of light left a cutting track on the runway, and the blocking plate set up behind also appeared densely packed with potholes.

If it is aimed at other spaceships, it can tear a hole in the spaceship in an instant.

Soon, driven by the manic plasma, the Qinglong class moved forward slowly, and the speed became faster and faster.

In less than 100 seconds, the battleship flew to the universe along the ramp runway. The moon with low gravity and no atmosphere is very convenient for taking off large spaceships.

It was just that as the Qinglong-class ship flew into the universe, the staff of the spaceport also controlled the robot to conduct a careful inspection of the runway.

The results are not optimistic.

The runway was cut with a very obvious crack by the plasma, the crack reached a depth of 4 to 6 centimeters and a width of 15 meters.

This situation basically means that the runway has been abolished.

The person in charge of the spaceport quickly reported the situation.

But there is no way above, after all, the destruction of the runway by ultra-high-speed plasma thrusters is basically unsolvable.

Existing spaceport runways are all made of six-claw silicon steel or bio-silicate polymers. No matter how good these materials are, they cannot withstand the impact of dense particles.

The high-speed plasma thruster is a necessary condition for realizing the high-speed navigation of the spacecraft, which is indispensable.

After discussions, the Development Research Departments of several departments came up with some proposals.

For example, reduce the landing of spacecraft equipped with high-speed plasma thrusters, and use special handover spacecraft to be responsible for the transportation between spacecraft, planets, and space stations.

Those spaceports that need to land are specially equipped with exclusive runways. This kind of runway has several requirements. The first is cheap, the second is disposable, and the third is convenient and quick maintenance.

After all, it is impossible not to land all the time. Homo sapiens' spacecraft needs to be overhauled once a year.

Of course, the company can also choose another option, which is to use the space dock, and arrange the annual maintenance work of the spacecraft in the space dock.

But now Homo sapiens owns a very large number of spaceships, including 758 military warships and 9673 civilian spaceships.

And this scale is still increasing every year.

However, Homo sapiens has only three space shipyards, and the remaining space shipyards and maintenance plants are all set up on the moons of the moon, Venus, Mars, and Jupiter.

Now we have to make two preparations. On the one hand, we need to increase the size of the space dock, and on the other hand, we need to transform a number of special ground spaceports to facilitate the landing of the upgraded spacecraft.
