Super technology leader

Delicate and rough, these are two states.

Other countries' measures on space junk are rude, and the navigator's measures on space junk are sophisticated.

How to put it, Meriken proposed a radical method to "clean up" near-Earth space.

One of their university research groups is studying a new technology that uses gas "pulses" to shoot space debris. The proposed new system is called the "Space Debris Removal System", which sends gas pulses to the target debris's necessary path. It increases the friction of space junk, causing it to fall into the earth’s atmosphere and burn.

There is also the National Aeronautics and Space Administration, which will invest in the development of two-dimensional spacecraft, which are made of special two-dimensional film materials that can wrap space debris and make it out of orbit.

Said it is a spacecraft, it is actually a "big net", and the working method is similar to the net gun that captures the drone.

Well, it's not too similar.

Anyway... I understand myself.

In addition, there are micro-electric propulsion devices using small satellites in the Taiqi Empire, which can safely bring satellites back to the earth’s atmosphere and burn them out in the air, thereby avoiding the generation of space junk and controlling the congestion of satellites in low-altitude orbits.

Other countries also install robotic arms for space equipment to cut solar cells...

Pooh, how could it be possible? The robotic arm is used to do business. The capture device can approach the space junk, and then extend the robotic arm to grab it, and then send it to high orbit so that it will not affect the flight of other spacecraft.

Or push it out of orbit and send it to the direction of the earth. Small rubbish burns in the atmosphere. After the big rubbish passes through the atmosphere, it is completely "buried" in the "spacecraft graveyard" in the South Pacific waters.

Well, that's basically it.

"Burn, burn, if you don't burn, how can the earth have a clean orbit, and how can mankind have a bright future!"

In fact, when there are no such "clean facilities", scientists can also deal with some space junk.

For example, in order to abandon an artificial satellite in low-Earth orbit, space engineers will slightly change its orbit to make it enter a lower orbit, and then enter the atmosphere and burn it in 25 years. This is called the "25-year rule" for artificial satellites.

Satellite fuel is very precious and cannot be used unless it is a last resort.

If you want to change the orbit without external thrust, every strand of fuel must be accurately calculated. Therefore, these satellites will only use the last remaining strand of fuel to add a thrust to the artificial satellite in the last few seconds after the fuel is consumed. They start to slow down and enter a descending orbit.

If the size of the artificial satellite is too large to be completely burnt during re-entry into the atmosphere, the last remaining fuel of the satellite will be used to slow down and derail it in a certain direction, so that the debris can fall in a remote area. This remote area can be called "Spacecraft Cemetery" is located in the South Pacific.

Well, this is a very famous place, where many well-known space equipment in human history are buried.

They are all big ones.

Humans just like the big ones. Of course, the bigger ones are more famous.

Of course, these are all satellites in low earth orbit, and the earth is not only low earth orbit, it also has artificial satellites far away from the earth, such as synchronous orbit.

If the obsolete satellite is in a very high orbit, then reducing its speed and de-orbiting it will require a lot of fuel, which is not available in the artificial satellite at the end of its life cycle.

Therefore, since it can't be sent back to the earth, then simply push such satellites to a higher orbit, which is called a "cemetery orbit."

In fact, pushing an obsolete remote satellite into such a higher orbit only needs to change the speed of 11 meters per second, and reducing its orbit to re-enter the atmosphere requires a change of 1,500 meters per second, so "fuel economy" "Sex" can be seen. Of course, budget-conscious engineers know how to do it.

The cemetery orbit is also called "junk orbit" or "abandoned satellite orbit". It is located more than 36,000 kilometers above the earth, several hundred kilometers higher than the farthest satellite, so as to ensure the safety of other normal satellites.

Satellites in "cemetery orbit" will continue to revolve around the earth for hundreds of years before gradually losing altitude.

Scientists are not worried about this distant future. Perhaps two or three centuries later, scientists of that era will have a way to remove the space junk.

As a result, after less than two or three centuries, the navigator has now begun to remove the space junk.

Burning space junk is too wasteful, and the navigator has to do fine work.

The equipment already in space orbit is too precious.

The worker bee 1 shuttled in the garbage belt for a while. Although it hit some space junk, the relative speed is relatively slow, so the impact is not great. It will not slam the space junk out, and then run normally to others. Satellites cause trouble.

Although the probability of hitting some space junk to cause trouble to other satellites is very low, it is not 100% all right.

Navigator is a responsible human company, it will not do that kind of thing.

Soon, Worker Bee 1 found the Tianxia communications satellite.

The camera on the Worker Bee 1 is not comparable to the cameras on the upper stage of the general rocket. Generally, satellites will have some photos before they go to the sky, but after the satellite enters into space, its final image comes from the camera on the upper stage of the rocket. Almost no one has seen the orbital conditions.

So just like watching space junk all the way, people finally saw the real operation of artificial satellites this time.

Then the iron hand of the Worker Bee 1 was ruthless, and directly grasped the solid structure on the satellite with its mechanical arm, and the Tianxia Space Administration had the permission to let the satellite put away the solar panels.

Fly faster like this.

Of course you can fly with the solar panel, but with such a big board, the Worker Bee 1 is certainly not afraid of the impact of space junk with armor, but if you fly back to the maintenance bay, the satellite may really be scrapped.

The satellite put away the solar panels, and the Worker Bee 1 began to transform. The two hatches were opened directly in the middle of the hull, and the robot arm put the satellite in gently.

This is a good satellite, but you can't just rush back all the way back in front of it, you have to protect it.

The better the protection, the easier it is to maintain and upgrade later.

After the satellite was safely transported back to the maintenance bay, he took the spacecraft into the maintenance bay, and then was fixed, and finally, turned off the lights!

Those who watched the live broadcast reacted.

"and then?"

"It's gone?"

Of course not, how could the navigator's work be so poor.

The maintenance bay is just a maintenance bay with machinery and equipment, but the most important thing is that it is large and empty enough to provide enough pressurized space.

Therefore, many manufacturing equipment is not available, and parts cannot be manufactured without manufacturing equipment. It needs to be used in conjunction with the manufacturing center.

This is also the reason why two maintenance compartments are installed on both sides of the manufacturing center.

The manufacturing center will be launched a week later.

The Yishan rocket needs to undergo some maintenance before launching into the manufacturing center.

At that time, astronauts will take the orbital shuttle to dock with the manufacturing center, and then enter the maintenance cabin through the manufacturing center.

As for the maintenance and upgrading of satellites, it is normal to wait a week.

Anyway, it is almost scrapped, if it can be overhauled and upgraded by the way, it will definitely make a profit.
