"Recycling of waste satellites, this is a key point to discuss next ..."

RAFT, this time is meeting, and the relevant issues of their meeting are the recovery of the satellite and the cleaning of space garbage.

Space waste is also known as spatial debris or track debris, is a human object other than the spacecraft in the universe, including the debris generated by the carrier rocket and spacecraft during the transmission process; airbeat surface material falls off, surface coating The paint plaque fell by the aging; the solid, liquid material of the spacecraft leakage, the rocket and spacecraft exploded, and the fragments produced during the collision.

According to the professional statement of rocket scientists, it is called "track fragment", but the average people are called "space garbage".

Don't underestimate these zero broken space rubbish, in the 21st century, according to statistics, the number of spatial fragments larger than 1 cm in diameter has exceed 110,000, and more than 1 mm is more than 300,000!

Nowadays, the satellite technology has developed in advance, and after the 21st century, Catherine is now, this figure will only only have a lot!

Catherine, who is in danger, I thought of this problem when I was at the beginning.

So RAFT, this time, it is discovering the problem of recycling of abandoned satellites and space garbage.

Space garbage is typically 7 to 8 kilometers from the near-ground track at a high 300 to 450 kilometers, while at a high speed of 36,000 km high, at a speed of 3 kilometers per second, according to the track inclinement collision The speed can even reach more than 10 kilometers per second, so it has a huge destructive force. Therefore, if space garbage collides with the artificial satellite, manned spacecraft or international space station, will endanger the life of the equipment and even astronauts, according to the calculation of space garbage in diameter to 10 cm, you can completely destroy the spacecraft, count millimeters Size space garbage is likely to make them unable to work.

In 1983 in the original era, the US Space shuttle "Challenger" collided with a piece of paint peeling of a diameter of 0.2 mm, causing the porthole to be damaged, and there is only to stop the flight. The Soviet "Salute-7" track station has also been damaged by such "dust" many times. 1986. "Ariana" rockets exploded after entering the track, becoming 564 10 cm sized wrecks and 2300 small fragments, this rocket debris makes two Japanese communication satellite to Huangquan! On September 15, 1991, the "discovery" flight plane launched in the United States almost collided with the Rocket debris of the Soviet Union. At that time, the "Discovery" is only 2.74 kilometers away from this "unusful guest". Fortunately, the command system on the earth will send a warning signal in time, it is from death.

In fact, before the arrival of the Aerospace Age, scientists have foreseen the problems of the impact of aerospace activities, such as comets or dust from outer space. In 1978,

NALDKESSLER pointed out to 2000. The danger of artificial space garbage will exceed the outer space dust, and may form "garbage belt in the low land track, which is later called" Kasler syndrome ".

In 1991, Kasler found that 1 kg of space garbage could hit a 1000 kg spacecraft and may produce more waste fragments with destruction capabilities. If the number of spacecraft on the track exceeds a critical value, this impact will produce catastrophic "chain reaction" or "avalanche effect".

In the face of such warnings and warnings, major aerospace agencies have set up a department that monitors space garbage. For example, the leadership department of space garbage research established by NASA "Track Debris Project Office".

In order to minimize the danger of spacecraft and space garbage collision, the US space surveillance network records all about 10 cm of fragments on the earth track in the case and tracks it at any time to display, in the 1990s. There is a record of space garbage for a long time to check that there is 8,500 space garbage. In 2005, this record reached 13,000. In 2006, due to the increase in anti-satellite trial, space garbage increased to 19,000 pieces. The data released by NASA this year reached 22,000. Size smaller fragments can not be directly tracked, estimated, 500,000, less than 1 cm, less than 1 cm, estimated that tens of millions of space garbage may exceed 4,500 tons.

Is the light monitoring, useful?

The answer is definitely negative.

So Catherine is at this time, it has already begun to prepare.

Developing a machine N is very necessary.

"We can use strong magnetic fields to stick space garbage, for this reason, we can design satellites as nuclear fuel, and we need a long cable ..."

"In order to maintain our orbit, we need a powerful engine."

"In addition. I think we still need to consider a problem - that is the material, the spam of garbage in space is very fast, if our machine itself collided, or our receiving device is hit ... this It is a disaster. "

People discuss in seven tongues.

"About this, please don't." Some people said: "We have made a partnership with the hive laboratory, and their tempered carbon nanofibrioma has high toughness, and the strength is comparable to diamonds, is a perfect material. And extremely high temperature, corrosion resistance, low temperature resistance ... "

In fact, how this material is manufactured, it has become a headache, because carbon nano is not a polymer material, natural degradation is not a decades, no way.

But this does not hinder Catherine to apply this product.

If you make a garbage to recover 50 garbage, no matter what to say, this garbage is worthy.

"Our customers are worldwide, but this is an international issue, our main goal, should be ... United Nations!"

Yes, Catherine's second goal, oh, it is the third goal, the third big head!

Since the UAE began to listen to Catherine, Catherine has risen to the position of the first big head in the Pentagon, and the original United Nations, the status of Catherine, is already a decline.

Oh ... Maybe they will be honored?

Although space garbage is now not much, but in the 21st century, the impact probability has risen to 4%, for satellite, this is a very dangerous probability, and Catherine believes that recycling space garbage is a long-term Research, this study should start from now, when the future is dangerous, you will sacrifice the killer, whether it is the US or the Soviet Union, will definitely come to find yourself ... Well, it is more likely, they Solve this international issue through the United Nations.

RAFT technology will not be limited to space garbage, as well as recycling of satellites, as for this, RAFT and NASA and Pentagon works.

This plan is more confidential, and many problems are also designed.

On the surface, this plan is "abandoned satellite", but who knows that it is really receiving, will it be waste satellite ...

Through this means, Americans can carry out space combats, destroyed from the Soviet satellites entering the space, and even capture the Soviet space station, and astronauts they want to get destroyed to moon.

So this plan is more strict than the garbage collection plan.

Catherine's tempered carbon nanotube fiber material has been entered into the federal government's sight. NASA has already planned to use this material to build a shell of the monthly base - this means excellent sealing and safety of the moon base Sex, for the astronauts inside, this is non-rewarded.

There is money in your hands, your heart is not panic, the current Americans are probably this concept and feel.

Only Nixon himself is relatively low for the moon plan, so the whole plan is now on the same, but it can't be as before, it is also possible to continue, the messenger plan, is already the limit of the current, but the moon base telescope, It has indeed brought a huge change and changes ...

"Here, it is the report of our new aerospace service ..."

The meeting continued, but the topic has been taken below.

With new materials, the price of escrop jacket suddenly increased by five times.

However, the effect is also very obvious, the weight of the weather is extremely declined, the next time the moon plan is ready to re-call the moon base, and this time, the new astronaut will wear this type of tempered carbon nanotubes. The material of the fibers enters the moon surface.

If it is not because the price is too high, these people are probably even if the rocket, the return cabin is used to use this tempered carbon nanotube fiber to manufacture better.

But unfortunately, this is almost impossible.

Of course, if the federal government can throw tens of billions, or can you ... but this is possible?

The answer is definitely negative.

The federal government has money, and it can't be burn like this ...

A new aerospace service, a new satellite plan, everything is in progress.

Human future is in the sea, and this is just the beginning.

......

"Then buy it!"

Catherine placed the case.

Kodak now let Catherine are very unhappy!

At the end of May, Catherine met a trouble, which made Catherine original good mood, gradually deteriorated.

Catherine is very uncomfortable, and the consequences are very serious ...

......

Second!

Trying to the code word, haha ​​~

There are three more oh ~ (untraway, it will be recommended, monthly tickets, and.
