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

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

It completes the space junk removal efficiently at a low price.

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

"You are doing a very good job, but in fact, 30 billion yuan is too little, which discourages most powerful competitors.

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

Now that the bid has been successful, the official cleanup of space junk will begin tonight.

The huge amount of space junk in orbit also poses a hazard to our company's space activities.

It's just that the money for the quality projector cargo box is more than 30 billion, even if the state does not organize bidding, after our technology is formed, it will be cleaned up for free. Zhou Yu said approvingly.

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

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

Huaxia and the United States jointly established the International Space Development Association, a non-profit organization, and are ready to use the 30 billion yuan to bid for a global bid to clean up space junk.

This is only an experimental operation, and if there are no corporate bids, they will also increase the bonus after consultation.

30 billion yuan wants to clean up space junk, this is completely fantastic, and 30 billion US dollars will not work.

But they happened to encounter the outbreak stage of Xinghuo Technology's material technology, and Xinghuo Technology happened to have low-cost and efficient cleaning technology.

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

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

It is equipped with a 100-square-meter two-dimensional spacecraft, and it is a cleaner who cleans up space junk.

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

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

This includes debris from launch vehicles and spacecraft and scrapped satellites.

Peeling off of the surface material of the spacecraft, aging of the surface coating and falling paint patches.

Solid and liquid materials leaked 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 low-earth orbit at an altitude of 300~450 km.

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

Depending on the orbital inclination, the relative velocity 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, a manned spacecraft or the International Space Station, it can endanger equipment and even the lives of astronauts.

A single piece of space junk with a diameter of 10 centimeters can completely destroy a spacecraft, and a few millimeters of space junk can make it impossible for them to continue working.

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

The satellite will be penetrated or destroyed in less than 1.5 seconds

As soon as you bump into it, it's devastating. The collision of satellites creates an avalanche effect.

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

At present, 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 two-dimensional spacecraft according to different orbital altitudes.

Two-dimensional spacecraft, which are made using a special two-dimensional thin film material that can encapsulate space junk and take it out of orbit.

The propellants of two-dimensional spacecraft are stored in solid form in the thrusters, which are extremely efficient chemical propellants.

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

Depending on the orbital altitude, the specifications of the 2D spacecraft are also different.

In low-earth orbit of 300~450 km, the two-dimensional spacecraft presents a microporous structure, and its thrusters are very small.

This is determined by the characteristics of the orbit, which has a thin atmosphere on it, and the two-dimensional spacecraft must overcome the resistance of the atmosphere.

This orbital altitude is already low, and there are very few spacecraft present.

After the two-dimensional spacecraft enveloped the space junk, it fell into the atmosphere and burned up directly due to the gravitational pull of the earth.

In a geosynchronous orbit of 36,000 kilometers, the two-dimensional spacecraft used becomes a dense material. Its propulsion is very large and numerous, in the shape of a small cylinder the size of a thumb.

It is already a complete vacuum, and the two-dimensional spacecraft does not spare a single speck of dust.

When a two-dimensional spacecraft wraps around space junk, it increases the Earth's attraction to space junk, and it gradually falls in the direction of Earth.

During the fall from high orbit to low orbit, many normal satellites will be encountered on the way.

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

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

The two-dimensional spacecraft can only be strengthened by means of self-control, so that it has the ability to maneuver over short distances.

In this way, normal satellites can be actively evaded, so that space junk will fall directly into the atmosphere and burn up.

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

For a period of time starting on the night of January 6, there was a constant dense stream of fireballs streaking across the sky.

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

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

At a time when other countries are very appreciative of this event, 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 environment for space development.

In addition to China and the United States, other countries launching civilian spacecraft must pay 88 yuan per kilogram to the organization for the maintenance of the space environment.

Only spacecraft that have paid into the fund will receive a standard spacecraft digital certificate and become a spacecraft recognized by a major country.

The existing civilian spacecraft are registered free of charge, and future civilian spacecraft can only carry out public services after registering for digital certificates.

The wool is out of the sheep, and it is impossible to want the two big countries to take the money to maintain the space environment by themselves.

To maintain the environment, we must collect the wool of other countries according to our own monopoly position.
