During this time, Fang Hong's layout in the field of cutting-edge science and technology was also increasing, and the "Natural Science Foundation" handed over to Yu Qiu was not idle.

The next day, in the morning.

Quietly living in the villa, Yu Qiuzheng and Fang Hong were staying together, she looked at each other and said: "If the project plan of the Sky Survey Space Telescope is announced, I am afraid it will cause a lot of controversy, and spend so much money to make a big gamble......"

Hearing this, Fang Hong said lightly: "What do they know? This project will not lose at all, even if the telescope itself fails to launch, but the accumulation of technology and the upgrading of the industrial chain are real, and the most important thing is the accumulation in the field of optical device technology, which is of great benefit to the relevant technical links of the semiconductor industry. ”

Fang Hong's layout in the semiconductor field and the creation of the whole industry chain, in order to avoid prematurely arousing Americana's vigilance, is now also secretly engaged, which can be said to be very low-key.

For example, the "Survey Space Telescope" project, which involves the technical research and development of optical devices, and related technologies will also be beneficial to the semiconductor industry in the future.

The most important thing is that in this way, there is no need to announce that it is vigorously engaged in semiconductors, and America can rest assured that it will not compete with you for business.

Now we have to act and keep a low profile, because many technical nodes need to be broken through, and jumping too happily is to increase the difficulty of technical research.

According to the current basic design framework, the space telescope is the "king of pigeons" Weber space telescope, as early as 1996, Webb space telescope began front-end research and development, the following year officially established the project, the original budget is 500 million US dollars, planned to be launched in 2007.

Now 2011 is almost over, the telescope has not been built at all, and the budget has been increased again and again, and the construction period has been postponed again and again.

To a large extent, it is necessary to ensure that it is truly foolproof, because if there is a slight mistake, it will be cool, and after launch, it will not be able to be repaired like the Hubble telescope, and failure will mean failure.

In addition to ensuring that nothing goes wrong, another key point is that the technology is harsh, precise to the extreme, and the research and development is extremely difficult, which is one of the reasons why the cost has been postponed year after year.

At present, the launch of this telescope has been postponed to 2014, but Fang Hong, as a traverser, knows that he will have to continue to pigeon in 2014, and the pigeon will not be launched until 2021, and the final budget will exceed the sky-high price of more than 10 billion US dollars.

The "Sky Survey Space Telescope" project to be promoted by the Natural Science Foundation will be officially approved at the end of this year, and it is expected to be officially launched in 2O2O, which will last up to about nine years.

Yu Qiu believes that the "Sky Survey Space Telescope" will cause huge controversy because Fang Hong has set an extremely outrageous budget figure for this project, reaching an incredible 75 billion yuan.

Not to mention that the outside world can't understand it, even Yu Qiu can't understand it.

Fang Hong looked at Yu Qiu and said with a smile: "The bright task of the Sky Survey Space Telescope is to explore the universe, which lasted nearly ten years, with a sky-high budget of 75 billion yuan, how many enterprises or scientific research units involved in research and development, they have orders, research and development tasks, and enough profits to bring up the technology, how many high-tech enterprises can be born in 75 billion yuan?" ”

Obviously, Fang Hong wants to support the development of the relevant technology industry chain through this kind of super-large-scale budget investment in basic scientific research projects.

On the surface, it seems to be very cost-effective, and the risk is huge, but even ten years later, the Sky Survey Space Telescope is launched and Fang Hong is bombed in the sky, because during this period, a group of enterprises that have accumulated a large number of advanced technologies have risen, and the weak technical foundation can be consolidated.

But the outside world obviously can't understand it, that's right.

Fang Hong just hopes that, he doesn't want to be understood by the outside world at all, and everyone really interprets the motives behind the strategic layout of the semiconductor industry chain, which will make Lao Mei vigilant and crazy suppression.

It is foreseeable that the budget of 75 billion yuan may not be enough, and counting the inflation of the past ten years, the total cost of launching and launching by 2O2O may exceed the budget scale of 100 billion yuan, and it is not necessary to double.

Others hope that the budget is as small as possible, but Fang Hong is the opposite, he wants to increase the budget for this project, and the drunkard no longer wants to drink.

The design of the Survey Space Telescope is larger than that of the Webb Space Telescope, which consists of 18 hexagons with a specular reflection structure, the first circle of six mirrors and the second circle of 12 mirrors, a total of 18 mirrors adding up to 25.4 square meters.

The specular reflection structure of the survey space telescope has been added to one circle, and the third circle will require 18 mirrors, and the three circles will have a total of 36 mirrors, adding up to an area of 50.8 square meters.

The Hubble Space Telescope currently in orbit is about 2.4 meters, while the Sky Survey Space Telescope will reach about 8 meters so far.

In order to be able to clearly observe the first ray of light of the Big Bang, the 36 mirrors of the Survey Space Telescope cannot have a polishing error of more than 10 nanometers.

It's no wonder that the launch is not planned until 2O2O.

On the one hand, it takes time for technology to catch up, and on the other hand, technology is so harsh that it is pure dream to get it done in three or four years.

At present, the overall design idea of the survey telescope has been released, and it is still being further improved and demonstrated, and the backs of 36 mirrors are controlled by multiple motors, which can achieve fine-tuning with 10nm accuracy.

In this way, there is no fear that the focus will not be on after launch, otherwise, without counting the potential value of the industrial chain, the sky-high investment of more than 70 billion or even 100 billion yuan will still have to be wasted.

The material of the mirror itself is beryllium, which is a lightweight metal, and in order to minimize the emission mass, beryllium is a good choice.

Although the strength of beryllium is not as high as that of steel, the Young's modulus of beryllium is higher than that of steel, that is, it is easier to break than steel but difficult to deform.

Beryllium can maintain a stable shape even before it breaks, but the reflectivity of beryllium is not very good, so in order to solve this problem, it is necessary to apply an ultra-thin gold coating to the mirror, which is also the case with the Webb Space Telescope.

Because the properties of gold are not very lively, and it does not change color in space, gold is very suitable as a reflective coating material, and the area of 36 mirrors over 50 square meters is actually not much, about 96.4 grams, or 3.4 ounces.

At present, the international gold price is 1,680 US dollars / ounce, that is, more than 30,000 yuan, and the simple calculation of gold prices is not much, but the actual situation can not be generalized, and the current launch cost alone is far more expensive than the value of gold itself.
