In addition, if space junk is not effectively cleaned up, it will be difficult for Wang Fan's more than 1,000 communication satellites to find sufficient orbital resources. Pen, fun, pavilion www. biquge。 info

No way, there are not many working spacecraft, but there is too much space junk!

Many of these spacecraft, which have been scrapped, still occupy superior orbital resources.

There is also a lot of space junk, so that other superior orbital resources are facing the threat of being attacked, thus losing their effectiveness.

Therefore, no matter what, Wang Fan must clean up these space junks in advance!

After all, space junk flies extremely fast, 6-7 km/s, and they have a huge lethality.

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

It can be said that once it hits, it is 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 debris 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, becoming 564 pieces of 10 centimeters in size and 2,300 pieces of small fragments.

Then Japan's two communication satellites will produce more space junk.

In this way, in the future, I don't know that the unlucky one will win the lottery again......

But Wang Fan's global WIFi plan requires thousands of satellites, which is as large as the total number of satellites in normal operation in the world.

At that time, it will definitely account for half of the country, no matter how you look at it, it will be the injustice of the lieutenant general!

Therefore, Wang Fan had to clean up in advance, so there was this operation.

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

The soldiers and horses did not move, and the grain and grass went first.

If we don't clean up this space junk, the current global WiFi program and other space projects in the future will have big problems.

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

But mortal starry sky can't do it, and you have to deal with it positively.

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

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

Therefore, the main means of dealing with these "cold killers" of space debris at present is to avoid them.

That's right, the main way at the moment is to can't be provoked and can afford to hide!

Through the establishment of an early warning mechanism, when it is confirmed that a spacecraft may collide with a larger space debris, various countries use the spacecraft's own power to maneuver and change orbits, so that the spacecraft can leave the original orbit that is in danger of collision with space debris and move to another safe orbit.

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

This avoidance behavior is only a temporary negative response.

For solving space junk, it does not do anything at all.

On the contrary, if this development continues, it will only lead to more and more space junk.

Once it reaches a certain level, it will be too late to dodge at that time!

On the contrary, if we want to solve the problem of space junk fundamentally, we need to recycle space junk in geosynchronous orbit and send it to the earth's atmosphere to burn it.

This would substantially reduce space junk, but it would be difficult, and although some ideas have been put forward by various countries, the effect is unfortunately limited.

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

And the American "space slingshot". In order to save fuel, Texas A&M University proposed that the "Slingshot-Satellite Space Sweeper" can capture space junk, and then throw space junk into the earth's atmosphere to burn, and then use momentum to sail to the next space wreckage target for removal.

Other electric debris elimination nets, "Space Debris Removal Method", "Electric Tether", "Clean Space One", "Deorbit Mission", ......

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

At present, the more mature solution is the space "scavenger" proposed by British scientists to --- cubic sails to bring abandoned satellites or failed rockets back to Earth.

The cubesail is actually a tiny satellite, weighing about 3 kilograms, and the dimensions are that it can carry rockets into space with other satellites, thus reducing costs.

A folded polymer membrane is installed inside the cube sail. Once launched into space, the membrane opens up to an area of up to 25 square meters.

The cubesail first enters space to unfold the film, then "docks" with the space junk, then carries the space junk back to the atmosphere, and finally crashes into the atmosphere and burns up!

While this is a good idea and a practical approach, the biggest problem is inefficiency.

The cube sail small satellite has an area of only 15 square meters, and its efficiency is really limited.

To do this, Wang Fan had no choice but to develop his own solution and test it today.

…………

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

This makes the attention of the mortal starry sky much higher.

The handover of the US president has reduced a lot of heat.

There is no way, the president of the United States is only a matter of domestic affairs in the United States, at most it concerns one country, and other people only pay attention to it when they are idle.

Even many Americans say that it is better to play games......

On the contrary, space junk is an international presence.

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

And how the mortal starry sky solves this problem has instead aroused the curiosity of people around the world and aroused everyone's interest.

At the same time, Obama was relieved to learn that the big move of the mortal starry sky turned out to be to clean up space junk.

This is a major event of public welfare and is worth advocating.

So Obama directly issued the last statement: space junk is urgent, and everyone is responsible for it!

It can be regarded as solidarity with the mortal starry sky, and it is also to leave a good name for himself.

There is no way, the show of politicians is everywhere, even if they are about to leave office.

And Trump was unequivocal and made a statement directly in the mortal language:

Praise for the mortal starry sky, after taking office, the control of space junk will be regarded as an important issue and written into the government memorandum!

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

Space junk has been around since the last century, and the United States is the main contributor!

But if the mortal starry sky is not governed, you two will not let out a fart.

Now that the mortal starry sky is about to take action, you are all running to rub the heat.

It's okay, it's very good!
