Modifying and designing satellites directly in space is a higher technology than launching rockets, but when the technology reaches a certain level, it is really cheap.

Moreover, it launches rockets less and generates less space garbage.

Even if it is recycled, they will still produce space garbage, but the difference between more and less than single-use rockets.

Not to mention that rockets will produce garbage, even satellites themselves can become garbage. After all, humans have been launching satellites for decades and have been scrapped, but there are still many satellites that remain in space orbit.

In fact, those scrapped satellites are not completely useless. Some of them are just because the fuel is used up and then they slowly lower their orbits, waiting for a day when they completely enter the atmosphere and are burned.

Many satellites like this can be used to retrieve and repair them, and then add some fuel.

One more repaired satellite will be less... no, a lot of space garbage.

And to be honest, satellites are really expensive, and you can save a lot of money by building one less.

Generally, the more expensive communication satellites are because they require a relatively large platform. However, humans enter the information society and their demand is high, so "expensiveness means very expensive."

Hey, don't worry about communication satellites being expensive, there are more ruthless than this.

The most expensive type of satellite is the optical strategic reconnaissance satellite.

This kind of satellite is the cheapest $5 billion per!

The most expensive one is over 10 billion US dollars per piece!

The familiar Hubble Telescope is actually an optical reconnaissance satellite, but it is quite special. To put it simply, it is to oppose the observation angle of the ground observation satellite to space. If you say more, you will not finish it in several days.

You just need to know that it's expensive.

In the era when the space shuttle in Meriken could still work, Hubble was repaired and repaired at all costs, because even if the huge space shuttle was flying for Hubble four or five times, the resources it consumed were more cost-effective than letting Hubble scrap and re-launch one.

The most modern giant optical reconnaissance satellite is worth a lot to the cost of a nuclear-powered electromagnetic catapult aircraft carrier!

Why are large-capacity communication satellites and strategic optical reconnaissance satellites so expensive?

That's because communication satellites are expensive on large-capacity carrier tubes, and one is 50. You should know that the "active Aegis system" on a warship worth thousands of tons is only installed with about 8 similar carrier tubes.

Optical reconnaissance satellites are expensive on super-large-diameter lenses. After all, each lens with a diameter of several meters is as long as one or two years. The mirror accuracy at the sub-nanometer level and nanometer level almost represents the limit level of human precision machining.

Think about how much it costs here.

There are no less than 4,000 medium and large satellites flying in the sky, but in fact there are only 1,000 effective ones, and there are more small satellites, and those things fall faster.

Among the nearly 3,000 large guys that have been scrapped, no less than half of them can be repaired, and the most valuable thing is the repair of large-caliber reconnaissance satellites and large-capacity communication satellites.

If the orbit of a large-capacity communication satellite is too high and will not reach it for a while, then the repair value of scrapped reconnaissance satellites with orbital heights of only 900 kilometers is extremely valuable.

Even just being able to remove the lenses and reuse them, each of which is worth billions of dollars.

So although the pilot does not launch a commercial cabin, but a commercial cabin, he thinks that he is not making money anymore. In fact, if it runs well, then making money can be much more profitable than a commercial cabin.

The most important thing is that all smaller commercial cabins are included? The manufacturing contract is in the hands of other smaller private aerospace companies.

They have obtained some technologies that Pilot and Tianxia Aerospace officially added? They can already make such orders.

I said that I would use the Heavenly Space Station plan to support people, technology, and company? That's what I said.

Those small cabin pilots will no longer be involved. The large cabin in the industrial area is its home field. After all, no one can do it if others want to do it.

The maintenance cabin was parked next to the Tiangong Space Station? Although it was not close, it could be seen by astronauts and space tourists inside.

Even using some photography equipment and telescopes, you can see more clearly.

The current live broadcast lens comes from a set of optical telescopes and cameras that are equipped with the space station.

In the camera, it did not dock with the upgraded Tiangong Space Station, but opened the door of the maintenance cabin in its own position.

The silver-white maintenance cabin door begins to open? Its opening speed is not fast, but because the cabin door is very large, so the opening angle is very obvious at every minute.

After waiting for the cabin door to open to an angle, netizens were a little shocked because the maintenance cabin was not as empty as people imagined, but a spacecraft.

It looks a bit like the Moon spacecraft, but it is a bit smaller in terms of proportion and has a more complex appearance.

There are several mechanical arms and mechanical frames outside it, which are obviously space engineering equipment, not just spacecraft.

"Is this the engineering spacecraft to be equipped in the plan? I didn't expect it to be directly stuffed into the maintenance compartment and launched, Niu Pi!"

"I thought it was empty inside, but I didn't expect the Navigator to surprise me again and again."

"This kind of nesting doll launch requires very high stability for the Rockets, and this time it was the Rockets' first flight. I have to say that the Navigator's courage is really extraordinary."

"I don't know if this spacecraft is manned or unmanned. When will it start carrying out its mission? I want to see it."

"It should be unmanned. Now unmanned technology is very mature. If a manned module is installed, the design and manufacturing of the spacecraft will be several times more complicated, so I feel that it will be almost done if it is designed as unmanned or remotely controlled."

"Indeed, this is not a battlefield, so there is no need to pay too much attention to flexibility, so it doesn't matter whether there is anyone or not, and no one can even bring its performance to the extreme."

"No matter whether it has anyone or not, I just want to see it catch satellites now. The robotic arms above are used to catch satellites, right? Get it done quickly!"

After the space boat slowly flew out, Pilot Space gave its specific data.

The length of the boat is indeed not as big as the Benyueqi. It is only 9 meters long and the diameter is only 5 meters, but the weight is not small, reaching an astonishing 100 tons.

In other words, it is a "little thing" with a length of 9 meters and a diameter of 5 meters, which is 25 meters long and a diameter of 7 meters, which is 20 tons heavier.

The reason it is so heavy is because it is "solid" and it does not have a manned pressurized chamber.

It can fly unmanned or remotely controlled, and then rush into the space garbage belt to "salvage" the scrap satellites mixed in the space garbage.

Yes, it carries a solid exterior armor just because it's going to rush the space garbage belt.

Its structure and shell are not the structure of ordinary space equipment. It is built according to the protective performance of armored vehicles.

Even the three main thrusters behind it are bulletproof and will not be damaged if they are hit by space garbage.

It is precisely because the three main propellers behind it are too conspicuous that before the pilot announced its name, netizens gave it a nickname called "Space Three Bouncers".
