Chapter 554 [Space Survey Telescope]

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

The next day, in the morning.

In Jingxinju Villa, Yu Qiu was staying with Fang Hong. She looked at each other and said, "If the project plan of the Sky Survey Space Telescope is announced, it may cause a lot of controversy. Spending so much money is a big gamble..."

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

Fang Hong's layout in the semiconductor field and the establishment of the entire industrial chain, in order to avoid prematurely arousing America's vigilance, are now also being done secretly, which can be said to be very low-key.

For example, the "Space Survey Space Telescope" project involved in the technology 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 to the outside world that it is vigorously engaged in semiconductors. Don't worry about America, I won't compete with you for business.

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

According to the current basic design framework, the target of the space telescope is the "King of King Pigeon" Webb Space Telescope. As early as 1996, the Webb Space Telescope began front-end research and development, and the project was officially approved the following year. The original budget was 5 billion and is scheduled to launch in 2007.

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

Doves like this, to a large extent, are to ensure that it is truly foolproof, because if something goes wrong, it will be cool. After launching, it cannot be repaired like the Hubble Telescope. Failure means that it is in vain. .

In addition to ensuring that nothing goes wrong, the Webb telescope has been pigeon-to-pipe. Another key point is that the technology is demanding, the precision is extremely high, and the research and development is extremely difficult. This is one of the reasons why the cost has been postponed year after year.

At present, the launch time of this telescope has been postponed to 2014, but Fang Hong, who is a traveler, knows that he has to continue to dove until 2014, and it will not be launched until 2021. The final budget exceeds the sky-high price of 100 billion U.S. dollars.

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

Yu Qiu believes that the "Space Survey Telescope" will cause huge controversy because Fang Hong set an extremely outrageous budget figure for this project, reaching an incredible 750 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 obvious mission of the Sky Survey Space Telescope is to explore the universe. It lasted nearly ten years, and with a sky-high budget of 750 billion, how many companies or scientific research units involved in research and development have orders? , With research and development tasks and sufficient profits, technology can be promoted, how many high-tech enterprises can be born with 750 billion yuan?"

It is obvious that Fang Hong wants to support the development of related technology industry chains through such super-large-scale budgetary investment in basic scientific research projects.

On the surface, it seems that it is not cost-effective, and the risk is huge, but even if it is ten years later, the sky survey space telescope is launched and Fang Hong is blown up in the sky. The weak technical foundation can be consolidated.

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

This is exactly what Fang Hong hopes. He doesn’t want to be understood by the outside world at all. If everyone understands the motivation behind the strategic layout of the semiconductor industry chain, it will make Laomei alert and crazily suppressed.

It is foreseeable that the budget of 750 billion yuan may not be enough. Taking into account the inflation of the past ten years, the total cost of launching into space by 2 may exceed the budget of 2 billion yuan, and it may not be doubled.

Others hope that the budget should be as small as possible, but Fang Hong is just the opposite. He tried to increase the budget for this project, and he wanted to stop drinking.

The design of the Sky Survey Space Telescope is larger than that of the Webb Space Telescope. The latter is a mirror reflection structure composed of 18 hexagons. The first circle is six mirrors, and the second circle is 12 mirrors. A total of 18 mirrors add up to 25.4 square meters.

The mirror reflection structure of the Sky Survey Space Telescope adds a circle, and the third circle needs 18 mirrors, a total of 36 mirrors in the three circles, and the combined area reaches 50.8 square meters.

The Hubble Space Telescope currently in orbit is about 2.4 meters, and the survey space telescope will reach about 8 meters so far.

In order to be able to clearly observe the first ray of light from the Big Bang, the 36 mirrors of the Sky Survey Space Telescope, the grinding error of each mirror cannot exceed 10 nanometers. If you want to see more light, The mirror has to be very large.

It is no wonder that it is not planned to be launched until 2O2O.

On the one hand, it will take time for the technology to catch up, and on the other hand, the technology is so demanding that it would be a dream to get it done in three or four years.

At present, the overall design idea of ​​the sky survey telescope that is still on the proposal book has come out, and it is still being further improved and demonstrated. There are multiple motors on the back of the 36 mirrors, which can achieve fine-tuning with a precision of 10 nanometers.

In this way, you will not be afraid that the focus will not be matched after launch. Otherwise, if the potential value of the industrial chain is not considered, the sky-high investment of more than 700 billion or even 1000 billion will still be in vain.

The material of the mirror itself is beryllium, which is a light metal. In order to minimize the emission quality, beryllium is a very 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, which means it is easier to break than steel but harder to deform.

Even beryllium can maintain a stable shape until it breaks, but the reflectivity of beryllium is not very good, so in order to solve this problem, an ultra-thin gold coating has to be applied to the mirror surface. This is also true for the Webb Space Telescope. in this way.

Because the property of gold is not very lively, and it will not change color in space, gold is very suitable as a reflective coating material. In fact, the area of ​​36 mirrors exceeding 50 square meters is not painted much, which is about 96.4 grams. That's 3.4 oz.

The current international gold price is 1680 US dollars per ounce, which is more than 3 yuan. It is not much to simply calculate the price of gold, but the actual situation cannot be generalized. At present, the launch cost alone is far more than the value of gold itself. expensive.
