The Technology Tree of Xueba

On January 6, 2025, just after the weekend holiday ended, Lu Jinming, general manager of Spark Aerospace, came to Zhou Yu's office.

He said with a smile on his face: Mr. Zhou, we went to compete for the international bid to clean up space junk, and our competition plan was finally approved.

It efficiently cleans up space junk 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 have done a very good job, but in fact, 30 billion yuan is too little capital, which discourages most powerful competitors.

Only we can clean up space junk at such a low price and make a profit.

Now that the bidding plan has been successful, the formal cleanup of space junk will begin tonight.

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

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

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

China and the United States jointly contributed 15 billion yuan, and other countries just waited and watched, and did not contribute a penny.

China and the United States jointly established the International Space Development Association, a non-profit organization, and plans to use the 30 billion yuan to bid for the global cleanup of space junk.

This is just an experimental action. If no company bids, they will also increase the bonus after consultation.

30 billion US dollars to clean up space junk is completely a fantasy, 30 billion US dollars will not work.

But they just happened to meet the explosion stage of Xinghuo Technology's material technology, and Xinghuo Technology happened to have a low-cost and efficient cleaning technology.

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

On the evening of January 6, at the ALS Space Center, today's mass projector cargo boxes were neatly stacked.

It is loaded with a 100-square-meter two-dimensional spacecraft, which is a cleaner to clean up space junk.

Its cost is very low, each piece of two-dimensional spacecraft costs less than one yuan, plus the cost of the mass projector, Xinghuo Technology still makes some money.

Space junk is man-made objects in space other than working spacecraft.

Including the debris and scrapped satellites generated during the launch of launch vehicles and spacecraft.

The shedding of materials on the surface of the spacecraft, and the paint plaques that have fallen off from the aging of the surface coating.

Solid and liquid materials escaping from spacecraft. Debris from explosions and collisions of rockets and spacecraft.

Space junk generally moves at a speed of 7-8 kilometers per second in a low-earth orbit at a height of 300-450 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 orbital inclination, the relative speed at the time of collision can even reach more than 10 kilometers per second. Therefore, it has great destructive power.

If space junk collides with an operating satellite, manned spacecraft or the International Space Station, it will endanger equipment and even the lives of astronauts.

A piece of space junk with a diameter of 10 centimeters can completely destroy a spacecraft, and space junk with a size of a few millimeters may make them unable to continue to work.

A piece of space junk with a diameter of 10 centimeters hits a satellite, which is equivalent to two cars traveling at 100 kilometers per hour colliding with each other.

The satellite will be pierced or directly destroyed within 1.5 seconds

Once hit, it is devastating. Collision of satellites creates an avalanche effect.

Each collision of space junk will not annihilate each other, but will produce more debris. Once the amount of space junk reaches a critical value, more and more chain reactions will inevitably occur.

According to monitoring, there are 200,000 pieces of space junk with a diameter of more than one centimeter, and more than 9,000 pieces of space junk with a diameter of more than 10 centimeters.

It is the large amount of space junk and its distribution at different orbital altitudes that makes it extremely difficult to clean up.

The mass projector cargo box projects different 2D spacecraft according to different orbital heights.

Two-dimensional spacecraft, this kind of spacecraft is made of special two-dimensional film materials, which can wrap space junk and make it leave orbit.

The propellant of the two-dimensional spacecraft is stored in the thruster in solid form, and they are extremely efficient chemical propellants.

A two-dimensional spacecraft with a size of 100 square meters weighs about 5 kilograms.

Depending on the altitude of the orbit, the specifications of the two-dimensional spacecraft are also different.

In the low-earth orbit of 300-450 kilometers, the two-dimensional spacecraft presents a microporous structure, and its propeller is very small.

This is determined by the characteristics of the orbit. There is a thin atmosphere on the orbit at this altitude, and the two-dimensional spacecraft must overcome the resistance of the atmosphere.

This orbital altitude is already very low, and very few spacecraft exist.

After the two-dimensional spacecraft wraps the space junk, it directly falls into the atmosphere and burns due to the gravitational force of the earth.

The geosynchronous orbit of 36,000 kilometers, the two-dimensional spacecraft used becomes dense material. Its propulsion devices are very large and numerous in number, and are shaped like small cylinders as thick as a thumb.

Here is already a complete vacuum state, and the two-dimensional spacecraft does not let go of any dust.

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

In the process of falling from high orbit to low orbit, you will encounter many satellites in normal operation on the way.

It is impossible for Xinghuo Technology to allow the space junk wrapped in the two-dimensional spacecraft to collide with the normal traveling satellite.

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

Only by strengthening the self-control means of the two-dimensional spacecraft can it have short-distance maneuverability.

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

Xinghuo Technology uses a mass projector to launch two-dimensional spacecraft of different specifications in different orbits. A total of 12 cargo boxes and 1,200 tons of two-dimensional spacecraft have been launched.

For a period of time beginning on the evening of January 6, dense fireballs continued to streak across the sky.

At first people thought it was the arrival of a meteor shower, but after media reports, they realized that it was cleaning up space junk.

After dozens of days of cleaning, Xinghuo Technology has cleaned up 99% of the space junk in orbit.

When other countries are very appreciative of this matter, boasting that China and the United States have done a good thing for the world.

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