Super technology leader

Upgrading the space telescope is very troublesome.

The Harper Telescope has been in orbit for thirty years, and since the space shuttle was retired, it has not been maintained or upgraded, so it is very old.

Originally, its successor, the Weber telescope, should have been launched years ago, but for various reasons, it has been dove again and again, until now, it has reached the launch of the "Survey" telescope into orbit.

In fact, it is not easy for the "survey sky" telescope to be launched, and even its name should be called the "survey sky" telescope or "sky survey optical cabin".

When Tianxia originally planned the Tiangong space station, the two sides of the core module were not exactly the same two experimental modules, but one of them was the experimental module, and the other side was a "surveillance module". The core equipment of this observation module was a diameter. Two-meter space telescope.

In other words, in the first version of the plan, the survey telescope was part of the space station and was "community flight".

However, in later studies, it was discovered that due to the operation of the space station itself, the activities of internal personnel, and the docking of spacecraft, it may cause certain vibrations to the space station. Excessive vibrations will seriously affect the imaging of the space telescope.

Therefore, in the later design, the telescope was removed from the planning of the space station. Instead, an independent "optical cabin" was used to fly with the space station on an orbit at a height of 400 kilometers, so it became a "common orbit flight."

Although the Sky Survey Telescope is no longer part of the space station, the Tiangong Space Station still allows it to retain the name "Surveillance".

After all, when it is later repaired, overhauled, supplied, and upgraded, it will dock with the space station and become a part of the space station.

With the development of human aerospace technology, it has become easier to manufacture and launch artificial space equipment, so that the number of space equipment has skyrocketed.

There are even tens of thousands of artificial satellites launched by some plans. Although they are very small, they cannot hold a large number. The number of artificial satellites in a plan may exceed the total number of artificial satellites launched by humans before.

There are more and more man-made devices in space, and astronomical telescopes on the earth have suffered.

Originally, the atmosphere is a great enemy of ground-based space telescopes. It blocks the telescope's observation of space, as if it makes the telescope "cataract".

Now countless artificial satellites are flying in space, reflecting light all the time, as if there are many cars coming across from you, and these cars are still driving far away and flashing you.

If you can still see the road, then you are really awesome!

At this time, it is much better to have a space telescope.

First of all, the influence of the atmosphere is reduced to a minimum. It will not disturb the image, super-high visibility, no background light scattered by the atmosphere, and will not be absorbed by the ozone layer to absorb ultraviolet rays. It has many benefits.

Moreover, the space telescope is also in space orbit, just like an artificial satellite, as long as it is not hit, it will not be affected.

It’s just that there will be more and more artificial satellites in the future. This is irreversible, because humans need more and more artificial satellites.

As for the ground-based astronomical telescopes, there is no other way. Apart from allowing the telescopes to adjust their operating time to avoid the most influential satellite clusters, the satellite manufacturing company can also "dark" the appearance of the satellites so as not to allow the satellites. The reflection is so powerful.

In addition to these, you can only launch more space telescopes, and if you can't afford it, you will have to wait for more space telescopes and spend money to rent them.

In fact, that's the case. There will only be more and more man-made facilities in space orbit. Just a few days after the sky survey optical capsule was launched, the inflatable space station on Meriken was launched.

The inflatable space station was in a compressed state when it was launched. After reaching the predetermined orbital position, it was inflated, and after a few hours, it expanded into a giant.

Its diameter has reached 10 meters, which is unprecedented in the space station, and its length has reached 17 meters. The habitable space directly reaches more than 1,000 cubic meters, which instantly exceeds the habitable area of ​​the Starry Sky Inn, winning "the largest single-space cabin for humans." "The title.

All of a sudden, Meriken Aerospace was proud of it.

After being suppressed by the Navigator for so long, they can be regarded as winning a round.

Although aerospace technology knows no borders, every advancement in aerospace technology represents the progress of human aerospace science and technology, but it has really fallen into reality, and there are still great differences between the two sides.

The official hasn't said anything yet, and the netizens on both sides started it.

"Haha, your navigator is not very good, but our Groo is even better. Your space station's single record has only been kept for a few days."

"Oh, your space station is very good for occupants. It's just an empty shell. You should decorate the rough room into a hardcover room."

"Envy is envious. It's nothing if we don't have decoration right now. Our foundation is big enough, so we can decorate as we like!"

"That is, no matter what you say, you can't change the fact that the Gro Space Station is more than twice the size of yours, and it is only one cabin, and the combination of two identical cabins is just a complete body!"

"There are also two cabins combined. You can use one of them first. At least the Navigator space station has been used, and the manned equipment is also used. Commercial space travel will also begin this month."

You come and go from both sides, Tang Chao also reads with gusto, but some information is not very accurate, for example, there is a "Navigator Space Station".

The space station of the Navigator Company is clearly called "Star Inn", and the small space station seems to use the company's name directly.

To prefix the name of "Navigator", at least it must be at the level of a space fortress or space city.

But Gro's inflatable space station is indeed big enough, but it's just big enough, it's empty inside, like a big balloon.

It’s not that it’s safe enough, but that the time from launch to formal operation is too long, because there is nothing in it and all the equipment needs to be transported up for installation, but the work efficiency in space is far lower than that on the ground. .

One is that the weightless environment is not friendly to delicate installation work, and the other is that astronauts are not as good as professional space station manufacturing engineers.

Adding the two together, the effectiveness and efficiency directly touch the bottom.

The most important thing is things that can be shipped at one time. You need to ship them in many times. This will not only extend the time, but the transportation cost will not decrease, and may even increase.

The only thing you get is the huge space station space.

After such a toss, it costs a lot, and the service life of the space station is limited, and the inflatable one has a shorter use time than the traditional space station.

In addition, it is positioned as a commercial space station, not only to pay back, but also to make money, so its pricing will definitely be weighed back and forth.

If it was before, its price will definitely be lower than that of the International Space Station, plus the space is large enough, and the competitiveness is quite good.

Not only can it attract commercial space tourists, it may also get orders from some countries.

But now it’s different. The space station of Navigator Aerospace has already gone to the sky first. Coupled with the use of orbital shuttles, the price on Navigator’s side is terribly low.

Well, relative to the traditional price in the aerospace industry.

In this case, Gro's commercial space tourism plan, I don't know how it will respond?
