Chapter 386: Trash is a Treasure

Delicate and brutal, these are two states.

Other countries' measures against space junk are rude, and the Navigator's measures against space junk are exquisite.

Anyway, Merrican has proposed a radical approach to "clean up" near-Earth space.

One of their university research groups is working on a new technology that uses gas "pulses" to shoot space debris, a proposed new system called the "Space Debris Removal System", which increases the friction of space junk by sending gas pulses into the path of the target debris, causing it to fall into the Earth's atmosphere and burn up.

There is also the National Aeronautics and Space Administration, which will invest in the development of a two-dimensional spacecraft made of a special two-dimensional thin film material that can encapsulate space junk and take it out of orbit.

It is said that it is a spaceship, but it is actually a "big net", and the way it works is similar to the net gun that captures a drone.

Well, not too similar either.

Anyway...... Understand for yourself.

In addition, there are miniature electric propulsion devices that use small satellites on the Obido Empire's side, which can safely bring satellites back to the Earth's atmosphere and burn them up in the air, so as to avoid the generation of space junk and control the congestion of satellites in low-altitude orbits.

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

Phew, how is it possible, the robotic arm is used to do business, the capture device can get close to the space junk, and then stretch out the robotic arm to grab it, and then send it to a high orbit so that it does not affect the flight of other spacecraft.

Or push it out of orbit and send it in the direction of the Earth, where the small garbage burns up in the atmosphere, and the large garbage passes through the atmosphere and is completely "buried" in the "spacecraft graveyard" in the waters of the South Pacific.

Well, that's pretty much it.

"Burn it, burn it, if it is not burned, 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 also have a way to 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 put it into a lower orbit and re-enter the atmosphere and burn it up within 25 years, which is known as the "25-year rule" of artificial satellites.

Satellite fuel is precious and cannot be used unless absolutely necessary.

If you want to change the orbit without external thrust, every trace of fuel has to be calculated accurately, so these satellites will only use the last remaining trace of fuel to add a thrust to the artificial satellites in the last few seconds after they have consumed fuel, so that they can start to slow down and enter descent orbit.

What if the satellites are too big to burn up completely during re-entry? So the last remaining fuel of the satellite will be used to slow it down and deorbit it in a certain direction? In order to allow the debris to fall in a remote area, which can be called a "spacecraft cemetery", the specific location is located in the South Pacific Ocean.

Well? It is a famous place where many well-known space equipment in the history of mankind are buried.

It's all big.

Human beings just like big ones, and the bigger they are, the more famous they are.

Of course? These are all satellites in low-earth orbit? And the Earth is not just in low-Earth orbit? It also has artificial satellites far from Earth, such as geosynchronous orbits.

And if the scrapped satellite is in a very high orbit? So reducing its speed, derailing it will require a lot of fuel? This is something that artificial satellites that are at the end of their life cycle do not have.

So, since it can't be sent back to Earth, then simply push such a satellite into a higher orbit? A place known as the "Graveyard Track".

In fact, pushing a scrapped far-Earth satellite into such a higher orbit would require only a 11 m/s change in speed, while lowering its orbit to re-enter the atmosphere would require a change of 1? 500 meters per second, so the "fuel economy" is visible, and the budget-conscious engineers certainly know how to do it.

The cemetery orbit, also known as the "junk orbit" or "abandoned orbit", is located more than 36,000 kilometers above the Earth, hundreds of kilometers higher than the farthest far-reaching satellites, so as to ensure the safety of other normal satellites.

Satellites in "graveyard orbit" continue to orbit the Earth for hundreds of years before gradually losing altitude.

Scientists are not worried about this distant future, and perhaps in two or three centuries, scientists of that era will have a way to get rid of this space junk.

As a result, it won't be two or three centuries later, and the Navigator will now start to remove this space junk.

It's too wasteful to burn the space junk, and the navigator has to do the delicate work.

Equipment that is already in orbit in space, that is too precious.

Worker Bee 1 shuttled through the garbage patch for a while, although it hit some space junk, but because of its relative speed, it did not have a big impact, it would not knock the space junk out hard, and then cause trouble to other normal satellites.

Although the probability of randomly hitting some space junk and causing trouble to other satellites is very low, it is not 100% fine.

The Navigator is a responsible human company that doesn't do that kind of thing.

Soon, Worker Bee 1 found the Tianxia communication satellite.

The camera on the Worker Bee 1 is not comparable to the camera on the upper stage of the general rocket, and there will be some photos before the satellite goes into space, but after the satellite enters space, its last images come from the camera of the upper stage of the rocket, and the real orbit operation of the satellite, almost no one has seen it.

So just like watching the space junk along the way, people finally saw the real artificial satellite operation this time.

Then the Iron Hand of Worker Bee No. 1 was ruthless, and directly grabbed the solid structure on the satellite with a mechanical arm, and the Tianxia Space Agency used the permission to let the satellite put away the solar panels.

Fly a little faster this way.

Of course, you can fly with solar panels, but with such a large board on the edges, Worker Bee 1 is definitely not afraid of the impact of space junk with armor, but all the way back to the maintenance module, the satellite may really be scrapped.

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

This is an intact satellite, and it can't just rush back all the way in front of it, so it has to be protected.

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

After the satellite is safely transported back to the maintenance module, it enters the maintenance module with the spacecraft, and then it is secured, and finally, the lights are turned off!

The talent who watched the live broadcast reacted.

"And then?"

"That's it?"

Of course not, how can the navigator be so up-to-the-bottom.

The maintenance cabin is just a maintenance cabin, there are machines, there are equipment, but the most important thing is that it is large and empty enough to provide enough pressurized space.

Therefore, a lot of manufacturing equipment is not available, and parts cannot be manufactured without manufacturing equipment, and it needs to be used with a manufacturing center.

That's why the two maintenance pods are located on either side of the manufacturing center.

As for the manufacturing center, it will be launched in a week.

The Yishan rocket undergoes some overhaul before it is launched to the manufacturing center.

At that time, there will be astronauts who will dock with the manufacturing center on an orbital shuttle, and then enter the maintenance module through the manufacturing center.

As for maintaining and upgrading a satellite or something, it's normal to wait a week.

Anyway, it's close to scrapping, if you can overhaul it and upgrade it by the way, it will definitely make a profit.
