Humanity is missing, luckily I have billions of clones.

Chapter 68 Ignite the fire!

At this moment, Li Qingsong couldn't wait to go to Earth to see what was happening there.

How could there be no industrial landmarks? How could there be none? All those years of development, so many people, such advanced technology… just gone?

There is no trace left at all?

It’s a pity that Li Qingsong can’t go at the moment.

Not only can people not go there, even sending a probe there is impossible.

Don’t be fooled by the fact that Li Qingsong has built a huge space base and owns a fleet of hundreds of warships, which seems to be extremely technologically advanced.

But in reality, these are just for show.

The emergence of these things is entirely due to a most important premise.

Roselle has low gravity and no atmosphere.

The advantages of these two conditions were too great in the early stages of civilization development, allowing Li Qingsong to possess so many space creations even though the human civilization of the national era was not as good as his.

It seems to be a simple matter of launching a probe, but this first involves a route planning problem.

Without a deep understanding of the planets in the solar system and without knowing their detailed orbits, masses, and gravitational field changes, how can we plan our route?
It is impossible to even plan the route, let alone use their gravity to accelerate or decelerate, let alone how to take various complex factors into consideration and make the final route calculation.

Launching a probe is not like just throwing a brick with great force.

Secondly, there is another issue to consider.

How can communication be maintained when the distance is so great, even as high as 150 billion kilometers?

Even if communication can be maintained, how can the probe be positioned? Even if it can be positioned, how can its orbit be precisely adjusted to ensure that it changes its trajectory when necessary and accelerates when necessary?
This series of problems involves extremely profound mathematical calculations, space observations and basic principles, and is extremely complex.

But at this moment, no problems could hinder Li Qingsong's determination.

He didn't care about much else.

In an instant, hundreds of thousands of clones were mobilized. Combining his previous knowledge reserves and the knowledge obtained from interrogating and reverse engineering the captives of the Bluetuk civilization during this period, Li Qingsong devoted all his efforts to the task of developing the earth probe.

The first area to be tackled was the deep space communication system.

Li Qingsong plans to deploy three large space antennas around Luoshen and Enemy Star respectively, and use them to maintain contact with the probes that are about to sail away.

Secondly, Li Qingsong began to allocate manpower to carry out the manufacture of the second, third, and even the tenth space optical telescopes.

If you want to get a deeper understanding of the detailed data of the eight major planets in the solar system, an optical telescope is essential.

The third is the manufacture of the detector itself. It must not only have extremely high reliability - after all, once it enters deep space, it will be impossible to touch it yourself, but also have extremely high precision and sensitivity.

The probe can only carry a limited amount of fuel, so it must be used prudently. If it wastes a little more, it may not reach its destination.

At the same time, it must be used when it is needed, and the time and amount cannot be wrong at all. Otherwise, it may fly to other places.

Fourth, it is the carrier used to launch this probe.

The method of using a spaceship to accelerate it to a certain level and then throwing it out as before will not work here.

A spacecraft can only carry a limited amount of fuel, and the acceleration it can provide is also limited.

There was no other way. Li Qingsong could only develop rocket technology, just like the human world had developed aerospace technology. However, he did not develop a single-stage rocket like the current interstellar missiles, but a multi-stage rocket. Only a multi-stage rocket could accelerate it to a sufficient speed to reach the earth in the shortest possible time.

Otherwise, it would be meaningless if it took decades or even a hundred years to get there.

Under the premise of maintaining the normal operation and manufacturing of the base, hundreds of thousands of clones work day and night with all their efforts.

Gradually, ten optical telescopes came to the vicinity of Rosene and began to observe the inner solar system non-stop, accurately measuring the mass and density of each larger celestial body.

Deep space communication technology also made breakthroughs one after another. Finally, several super-giant antennas with a diameter of 100 meters and an area of about 8000 square meters were assembled in space.

They form a plane that is exactly perpendicular to the ecliptic plane.

Three giant antennas forming an isosceles triangle with Rosene as the center form an array. With the cooperation of the ground communication base, they achieve the effect of an antenna with a diameter equivalent to 4000 kilometers.

On the enemy planet, Li Qingsong made the same arrangement, also setting up three giant antennas to form an array.

In the precision machining workshop, hundreds of clones, with the help of equipment, concentrated their efforts and produced the various components of the detector bit by bit with an attitude that was more meticulous and serious than soldering transistors on a circuit board.

In the space factory, a super-giant three-stage rocket with a length of 230 meters and a diameter of 20 meters was slowly assembled.

Moreover, not just one, but five were built at the same time.

They have undergone multiple rounds of test runs at ground bases, but Li Qingsong is still not very confident about the overall situation.

Even humans on Earth have never built a rocket this big.

So Li Qingsong decided to conduct a test.

Approximately 40,000 tons of liquid hydrogen and liquid oxygen were poured into the massive rocket. Following a single ignition command, an incomparably intense flame erupted from the rear of the rocket, propelling the massive rocket, which had a total mass of over 60,000 tons, to accelerate and slowly break free from the gravity of Luoshen.

But the good times didn't last long. Before it flew far, it exploded with a loud bang.

Tens of thousands of tons of liquid hydrogen and liquid oxygen turned it into an unprecedented giant bomb, like a sun, directly illuminating the dim land of Luoshen.

But it doesn’t matter, Li Qingsong still has four.

Quickly search for wreckage, analyze data, find fault points, and make subsequent modifications and optimizations...

The second rocket also failed to succeed, the cause of the failure being a failure of the second stage to ignite.

The third was also unsuccessful due to hydrogen embrittlement, which caused the fuel to leak.

Even the fifth rocket failed. Undeterred, Li Qingsong built five more giant rockets based on his previous experience.

After failing three more times, he finally succeeded on the fourth attempt, and Li Qingsong's technical skills gradually matured.

This fifth rocket will take on the mission of launching that small probe.

It was carefully placed on top of the rocket.

At the same time, deep space communication networks, orbit calculation, tracking, positioning, etc. are all ready.

ignition!
