Chapter 1146 Intriguing Action

Just today, Mortal Starry Sky suddenly issued a statement that there will be a new big move tonight.

And the big move is on the 20th!
That's right, when Heed went down and Donald Epson came in.

Judging from the current situation, Mortal Starry Sky's actions are hardly friendly, and more than 90.00% of them are malicious.

But the meaning behind this is intriguing.

Is it a farewell to Sid or a welcome to Donald Epson?
In other words, is it revenge against Sid, or a warning to Donald Epson?
Or both?
It's hard to say.

After all, mortals have always been unconstrained in their work in science and technology, and they don't play cards according to the rules!

On the other side, Sid and Donald Epson, who received the news, both changed their expressions drastically, as if they were facing a formidable enemy.

Of course he was even more angry.

Sid was angry. Naturally, at this time, Wang Fan still didn't let him go, and he wanted to see him off at the end.

What made Donald Epson angry was that Sid was to blame. Could it be that he was going to take the blame for this once he came to power?
Even the White House looked nervous.

Frankly speaking, the time when the two governments are handing over is the weakest and the most prone to accidents.

But Wang Fan chose this time to make troubles, which is completely understandable as a provocation to the US government.

If others existed, if they dared to find trouble at this time, the US government would have dispatched F-22s, and even naval, air and marine corps, and then went to other countries to enforce the law and maintain world peace.

But for mortal technology, for Wang Fan, he really dare not!
There is no way, the military GPS is under the manipulation of others, what else can you do?

Without navigation, everything is in vain!

But for such a situation, both parties have no choice but to wait for the time to come, and then play by ear!
Therefore, the focus of the world that day was divided into two parts.

Part of it is to watch the handover of the US president. After all, as a superpower in the United States, it is still very important to change the head of state.

The other part is to see the big action of the mortal starry sky!

After all, Mortal Technology has never disappointed people, let alone Mortal Starry Sky!
It's just that I don't know what kind of big moves Mortal Starry Sky will make today.

More importantly, from the beginning to the end, Mortal Starry Sky officials did not make any explanations or explanations.

It was not until 12 noon that Mortal Sky released some information, but it was about space junk.

Space junk, also known as space debris or orbital debris, refers to man-made objects in space other than working spacecraft, including debris generated during the launch of launch vehicles and spacecraft, scrapped satellites, and surface materials of spacecraft. Peeling, paint plaques from the aging of the surface coating; solid and liquid materials leaked from the spacecraft; debris produced during the explosion and collision of rockets and spacecraft.

It can be said that space junk is as small as artificial satellite fragments, paint flakes, and dust, and as large as the entire spaceship wreckage.

The meaning is very simple. Space junk mainly has another characteristic: First, it is man-made.

Two is useless!
Like a lot of satellites, scrapped, out of control, stopped working...

As long as it loses its function, it is space junk.

But these satellites, or debris, dust, etc., still exist in space.

From October 1957, 10, the former Soviet Union successfully launched the world's first artificial earth satellite "Sputnik 4", and its abandonment was the beginning of "white pollution" in space.

What followed was a large-scale outbreak of space junk.

Especially with the rapid development of aerospace technology around the world, space launch activities have become unprecedentedly prosperous.

Countries that have the ability to launch by themselves, launch by themselves.

Those who are unable to launch by themselves will entrust other governments or companies to launch!
At present, there have been more than 4000 space launch records in the world, and more than 6000 spacecraft have been launched, but there are less than 3000 spacecraft in orbit, and only about 1000 are working normally!
In other words, more than 5000 other spacecraft have become space junk.

Ironically, there are 2000 more still in orbit!
Although most of the scrapped spacecraft fell into the atmosphere and burned up, there are still nearly 4500 tons of space junk in orbit around the earth.

According to big data statistics, as of November 2016, there were about 11 million pieces of space junk orbiting the earth, of which 1 pieces were more than 27000 centimeters in diameter, and were tracked by NASA and the Department of Defense.Each piece of space junk travels at a speed of 10 km/h.

A simple analogy, a space orbit, is a road.

The spacecraft in orbit is the car.

Space junk is scrapped cars!
These scrapped cars are still in orbit, which will inevitably affect the normal operation of other spacecraft.

The existence of a large amount of space junk not only occupies orbital resources, especially the geosynchronous orbit, which affects the launch of subsequent spacecraft, but also affects the normal operation of other launched spacecraft, and even causes major accidents.

There are countless examples like this.

As early as 1983, the American spacecraft "Challenger" collided with a paint peeling object with a diameter of 0.2 mm, which caused damage to the porthole and had to stop flying.

The "Salute-7" orbital station of the former Soviet Union has also been damaged by such "dust" many times.

In 1986, the "Ariane" rocket exploded shortly after entering orbit, becoming 564 pieces of wreckage 10 cm in size and 2300 small pieces. The wreckage of this rocket killed two Japanese communication satellites!
On September 1991, 9, the "Discovery" space shuttle launched by the United States almost collided with the rocket wreckage of the former Soviet Union. At that time, the "Discovery" was only 15 kilometers away from this "uninvited guest"!

On February 2009, 2, two communication satellites of the United States and Russia collided in space and produced a large amount of space junk, which is very likely to pose a threat to the International Space Station.

……

According to calculations, for each flying object in space orbit, the probability of a catastrophic collision event is 3.7%, and the probability of a non-catastrophic collision event is 20%.

Based on this calculation, in the future, a collision between space junk and a spacecraft may occur every 5 to 10 years, and by 2020 it will reach once every 2 years.

Wang Fan's global WIFi plan requires thousands of communication satellites.

However, there are only more than 1000 satellites in normal operation in the world at present. Once the deployment and launch of the global WiFi project is completed, the number of satellites will suddenly increase, and the incidence of space traffic accidents will inevitably double!
Wang Fan has more than 1000 satellites, with a large base, and he is most likely to win the jackpot.

At that time, if it causes losses every day because of this matter, it will be cheating.

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.
