Chapter 1147 Space Junk
In addition, if space junk is not effectively cleaned up, it will be difficult for Wang Fan's more than 1000 communication satellites to find enough orbital resources.

No way, there are not many spacecraft that work normally, but there are too many space junks!
Many of these spacecraft that have been scrapped still occupy superior orbital resources.

There is still a lot of space junk, which makes other superior orbital resources face the threat of being attacked, thus losing their function.

Therefore, no matter what, Wang Fan must clean up these space junks in advance!
After all, space junk flies at an extremely fast speed, 6-7km/s, and they have a huge lethality.

Once a piece of space junk weighing 10 grams hits a satellite, it is equivalent to two 100km/h cars colliding with each other, and the satellite will be pierced or directly destroyed within 1.5 seconds!

It can be said that once it hits, it will be a devastating disaster!

But this kind of accidental accident is not a headache, on the contrary, the most troublesome thing is the "avalanche effect"!
Every time space junk collides with each other, it will not annihilate each other, but will produce more fragments and more space junk.

It can be said that this is a vicious circle that will create more new "big problems"!
For example, in 1986, the "Ariane" rocket exploded shortly after entering orbit, and became 564 pieces of wreckage with a size of 10 centimeters, and 2300 small pieces. The wreckage of this rocket directly killed two Japanese communication satellites. Mourning Huangquan"!
Then Japan's two communication satellites will produce more space junk.

In this way, in the future, the unlucky one will win the lottery again...

But Wang Fan's global WIFi plan requires thousands of satellites, which can catch up with the total number of satellites in normal operation around the world.

At that time, it will definitely take up half of the country. No matter how you look at it, it will be taken advantage of by the lieutenant general!

Therefore, Wang Fan had to clean up in advance, so he took this action.

Moreover, as early as a long time ago, Wang Fan began to study the possibility and specific plans of cleaning up and recycling space junk.

If the soldiers and horses are not moving, the grain and grass will go first.

If these space junks are not cleaned up, there will be big problems in the current global WiFi plan and other space projects in the future.

Therefore, in the face of space junk, the United States, Russia, China, Europe, Japan, and South Korea can all respond negatively.

But the mortal starry sky is not good enough, so we have to actively deal with it.

However, in order to solve space junk, countries have put forward many ideas, but the effect is limited.

After all, space junk exists in space, not on the ground, so it is impossible to sweep it up and get it done.

Therefore, the main means to deal with the "cold killers" of space debris at present is to avoid it.

That's right, the most important way at the moment is still not to be provoked, to be able to hide!
By establishing an early warning mechanism, each country uses the power of the spacecraft itself to maneuver and change orbits when it is confirmed that the spacecraft may collide with larger space debris, so that the spacecraft leaves the original orbit where there is a risk of collision with space debris, and transfers to another safe track.

But you can hide for a while, but you can't hide for a lifetime.

This avoidance behavior is only a temporary negative response.

It doesn't do anything to solve space junk at all.

On the contrary, if this development continues, there will only be more and more space junk.

Once the number reaches a certain level, it will be too late to avoid it at that time!
On the contrary, if you want to fundamentally solve space junk, you need to recycle the space junk in geosynchronous orbit and send it to the earth's atmosphere to burn it.

This will substantially reduce space junk, but it is full of difficulties. Although all countries have put forward some ideas, unfortunately the effect is limited.

For example, Russia plans to start developing a spacecraft called "Sweeper" in 2018 to send space junk to a higher space orbit, or send it to the earth to land in the Pacific Ocean.

There is also the "Space Slingshot" of the United States.In order to save fuel, the Texas A&M University proposed that the "slingshot-satellite space cleaner" can capture space junk, throw the space junk into the earth's atmosphere and burn it, and then use the momentum to sail to the next space debris target for removal.

Other Electric Debris Removal Networks, "Space Debris Removal Act", "Electric Tether", "Clean Space One", "Deorbiting Missions"...

Although there are many tricks, they are all too immature.

The more mature solution at the moment is the space "scavenger" proposed by British scientists-cube sails, which are used to bring abandoned satellites or malfunctioning rockets back to Earth.

Cube Sail is actually a tiny satellite, weighing about 3 kilograms and measuring [-] ft. It can be carried into space with other satellites on a rocket, thereby reducing costs.

Inside the cube sail is a folded polymeric membrane.After launching into space, the membrane will open up to an area of ​​25 square meters.

The cube sail first enters space to unfold the film, then "docks" with the space junk, then returns to the atmosphere with the space junk, and finally falls into the atmosphere and burns up together!
Although this is a good idea and a feasible method, the biggest problem is the low efficiency.

Cube Sail small satellites only have an area of ​​15 square meters, and their efficiency is really limited.

For this reason, Wang Fan can only develop his own solution and conduct a test today.

…………

Space junk is related to the space exploration of the entire human being and the development of science and technology around the world, so it has naturally attracted the attention of many people.

This makes Mortal Starry Sky's attention much higher.

One ebbs and another, the handover of the US president has dropped a lot of heat.

No way, the President of the United States is only a domestic matter in the United States. It is at most related to one country, and other people only pay attention to it when they are idle.

Many Americans even said that it is better to play games...

In contrast, space junk is an international existence.

More importantly, this is almost an unsolvable problem at the moment, and all ideas are in the process of research and development.

How Mortal Starry Sky solves this problem has aroused the curiosity of people all over the world and aroused everyone's interest.

At the same time, Sid was decisively relieved when he learned that Mortal Starry Sky's big move was to clean up space junk.

This is a major public welfare event, and it is worth advocating.

So Sid directly issued the last statement: space junk, there is no delay, everyone's shared responsibility!
It can be regarded as solidarity with Mortal Starry Sky, and it is also leaving a good name for himself.

There is no way, politicians put on shows everywhere, even if they are about to leave office.

And Epson was also unequivocal, and directly issued a statement in Fanyu:

Like Mortal Starry Sky, after taking office, will treat space junk as an important issue and write it into the government memorandum!

The space pollution show of the old and new presidents left many people speechless.

Space junk has existed since the last century, and the United States is the most important contributor!
But if the mortal starry sky is not governed, neither of you farts.

Now that Mortal Starry Sky is about to launch practical actions, you all come here to catch the heat.

This is fine, very fine!
