The Technology Tree of Xueba

On January 6, 2025, at the end of the weekend holiday, Lu Jinming, the general manager of Spark Space, came to Zhou Yu's office.

He said with a smile: "General Manager Zhou, we are going to compete for the international clearance of space trash, and our competition plan was finally passed.

It completes space junk cleaning efficiently at a low price.

With the unanimous approval of the international expert group, we can harvest this project of up to 30 billion yuan. "

"You are doing a very good job. Actually, the amount of 30 billion yuan is too small, so that most of the strong competitors are discouraged.

Only we can clean up space junk at such a low price, and it is also profitable.

Now that the bidding scheme is successful, the space junk will be officially cleared tonight.

The huge amount of space trash in orbit has also caused harm to our company's space activities.

It's just the money for the quality projector container, that's more than 30 billion. Even if the country does not organize bidding, after our technology is formed, it will be cleaned up for free. Zhou Yu applauded.

Huaxia and the United States reached the "Space Development Convention", one of which is to jointly maintain the space environment and clean up space debris accumulated in orbit.

Huaxia and the United States jointly invested 15 billion yuan, other countries just waited and see, and did not pay a penny.

Huaxia and the United States jointly established the International Space Development Association, a non-profit organization, which is planning to use this 30 billion yuan to bid for a global space cleaning program.

They are just an experimental action, and if there is no corporate bid, they will raise the bonus after consultation.

30 billion yuan in wanting to clean up space trash is completely heavenly, not even 30 billion US dollars.

However, they happened to be in the outbreak stage of Spark Technology's material technology, and Spark Technology had a low-cost and efficient cleaning technology.

Lu Jinming used this technology to bid directly, and they had no competitors at this price and were immediately approved.

On the evening of January 6, at Alxa Space Center, today's mass projector cargo boxes are neatly packed.

It is loaded with 100 square meters of two-dimensional spacecraft, and it is a cleaner who cleans up space trash.

Its cost is very low. The cost of each two-dimensional spacecraft is less than one yuan. In addition to the cost of a mass projector, Spark Technology still makes money.

Space junk is an artificial object in space other than the working spacecraft.

Includes debris and scrapped satellites from launch vehicles and spacecraft during launch.

The material on the surface of the spacecraft is peeled off, and the paint on the surface coating is aging.

Solid, liquid materials leaked from spacecraft. Debris generated during rocket and spacecraft explosions and collisions.

Space junk generally moves at a speed of 7 to 8 kilometers per second in a low-Earth orbit at a height of 300 to 450 kilometers.

In the geostationary orbit at an altitude of 36,000 kilometers, it moves at a high speed of 3 kilometers per second.

According to the relative velocity of the orbital inclination, it can even reach more than 10 kilometers per second. So it has tremendous destructive power.

Collisions of space debris with operational satellites, manned spacecraft or the International Space Station can endanger the lives of equipment and even astronauts.

A piece of space junk with a diameter of 10 centimeters can completely destroy the spacecraft, and a few millimeters of space junk may prevent them from working.

A piece of space debris with a diameter of 10 cm hits a satellite, which is equivalent to two cars at 100 km / h colliding with each other.

The satellite will be penetrated or directly destroyed in 1.5 seconds

When it hits, it is devastating. The satellite collision caused an avalanche effect.

Each collision of space trash will not annihilate each other, but will generate more debris. Once the amount of space trash reaches a critical value, it will inevitably have more and more chain reactions.

According to the monitoring, there are 200,000 space trash with a diameter of more than one centimeter, and more than 9,000 space trash with a diameter of more than 10 cm.

It is the large amount of space trash that is also distributed at different orbital heights, which makes it extremely difficult to clean up.

The mass projector container projects different two-dimensional spacecraft according to different orbital heights.

Two-dimensional spacecraft, which is made of a special two-dimensional thin-film material, can wrap space trash and leave it in orbit.

The propellants of two-dimensional spacecraft are stored in the propeller in solid form. They are extremely efficient chemical propellants.

A two-dimensional spacecraft measuring 100 square meters weighs about 5 kilograms.

The specifications of the two-dimensional spacecraft vary depending on the orbital height.

In 300-450 kilometers of low-Earth orbit, the two-dimensional spacecraft exhibits a microporous structure, and its thruster is very small.

This is determined according to the characteristics of the orbit. There is a thin atmosphere above the orbit at this height. The two-dimensional spacecraft must overcome the resistance of the atmosphere.

This orbit is already very low, and very few spacecraft exist.

After the two-dimensional spacecraft wrapped up the space trash, it fell into the atmosphere and burned directly because of the gravity of the earth.

With 36,000 kilometers of geosynchronous orbit, the two-dimensional spacecraft used becomes dense material. Its propulsion device is very large, and the number is very large. It is a small cylinder with the thickness of a thumb.

It is completely vacuum here, and the two-dimensional spacecraft will not let any dust through.

After the two-dimensional spacecraft wraps up the space trash, it will increase the attraction of the earth to the space trash, and it will gradually fall toward the earth.

In the process of falling from high orbit to low orbit, many normally operating satellites will be encountered on the way.

Spark Technology cannot make space debris wrapped by a two-dimensional spacecraft collide with a normal satellite.

This will generate more space trash and affect normal space activities.

Only by strengthening the self-control means of the two-dimensional spacecraft can it be provided with short-range maneuverability.

This can actively avoid normal satellites and allow space junk to fall directly into the atmosphere and burn.

Xinghuo Technology used mass projectors to launch two-dimensional spacecraft of different specifications to different orbits, and launched a total of 12 cargo containers and 1,200 tons of two-dimensional spacecraft.

For a period of time starting in the evening of January 6, dense fireballs continued to flow across the sky.

At first people thought it was the arrival of a meteor shower ~ www.NovelMTL.com ~ After media reports, I realized that this was cleaning up space junk.

After dozens of days of clearing, Spark Technology cleared 99% of the space junk in orbit.

In other countries, they have praised this matter very much, boasting about China and the United States doing a good deed for the world.

The International Aerospace Development Association announced that in order to maintain a normal space development environment.

Except for Huaxia and the United States, other countries that launch civilian spacecraft must pay to the organization a space environment maintenance fund of 88 yuan per kilogram.

Only spacecraft that have paid for the fund will obtain a standard digital certificate for the spacecraft and become a spacecraft recognized by a large country.

Existing civil spacecraft are registered free of charge. In the future, civil services will only be able to start public services after registering a digital certificate.

Wool comes out of sheep, and it is impossible for the two great powers to pay for the space environment.

If the environment is well maintained, we must scoop wool from other countries according to our monopoly position.
