Chapter 903 is not out of the question

Month. Asked for a ticket.

The aerospace industry includes many things, and the four high-precision equipment of rockets, spacecraft, artificial satellites, and space stations cannot cover a single thing, and can even be said to be only a small part of the entire space system.

Although China is one of the world's leading space powers, there is still a big gap between China and the United States, Russia, and Europe, which occupy the highest peak of the earth's aerospace industry, and especially compared with the Americans. Not to mention anything else, just talking about space telescopes, the Sky No. 1 space station has been under construction for many years, but there are few reports on space telescopes in domestic news media.

As early as 2001, when the Shenzhou-2 spacecraft was launched, it was equipped with an orbital space telescope, but in terms of service life, professionalism and functionality, this orbital space telescope is far inferior to the Hubble Space Telescope. More importantly, after this orbital space telescope, Huaxia has no follow-up development plans.

At present, the Cosmic Ray and High Energy Astrophysics Open Laboratory of the Institute of High Energy Physics of the Chinese Academy of Sciences is jointly carrying out scientific research with several universities in China, hoping to make every effort to develop a hard X-ray modulation telescope. As well as miniature astronomical satellites with a mass of less than a hundred kilograms. However, these things can not be done casually, space telescopes, like satellites, are high-precision technologies that belong to the United States, Europe, Japan and other countries to strictly control the import and exchange of information in China, and what China's scientific research workers can do is to complete a series of research independently according to Kao's own strength, self-reliance, and independence. The difficulties encountered in this process are innumerable, and they can only make people tired.

Of all the space telescopes, the Hubble Space Telescope is undoubtedly the most famous, but not the only one. The United States, Europe, Russia, Japan, South Korea and other countries have successively sent space telescopes into space. These space telescopes have different functions and are constantly trying to interpret the universe from different angles.

For example, the space telescope carried by the third-generation solar observation satellite "Sunshine B," launched by Japan in the summer of 2006, is mainly used to observe the sun, and the space telescope jointly developed by the ROK, NASA, and the University of Berkeley in California has undertaken the main task of drawing the world's first "all-day map" in the far infrared field.

The observation of space not only helps people understand the origin of the universe and establish a model of the entire universe, but also can better detect all kinds of celestial phenomena in space, providing a safer route for human beings to carry out interstellar travel. Although Liu Shiqing can use the signal receiver to search for relevant information, he does not dare to believe 100% of the information in this regard, after all, the information is dead, space activities are alive, who can guarantee the relevant records of the Galactic Federation, it must be accurate, after all, this thing does not tolerate half a point cuò. But if there is the slightest mistake, it is very likely to lead to extremely strict consequences.

In any case, the space telescope must be built and launched to pave the way for the subsequent construction and research of the galaxy. As a result, there is a problem here, Galaxy Industry does not have the conditions to manufacture spaceships at all, whether it is the reserve of technical personnel or the situation of equipment, there are deficiencies.

Cooperation with the state has become Liu Shiqing's only choice, not to mention, if he wants to build a space telescope, no matter how good the secrecy measures are, and then put them in place, when they are launched, they will not be able to keep it secret. This is not only the case for space telescopes, but also for the space stations, space factories, and moon bases to be built by Galaxy Space, which are impossible to achieve complete secrecy. After all, there are hundreds of professional astronomical observatories on the earth, and there are tens of thousands of astronomy enthusiasts, and they have professional or professional astronomical telescopes that stare at the space around the earth all day long. Whatever comes out, you can see it clearly.

Liu Shiqing thought very clearly, rather than waiting until the last moment to communicate with the country and the military, it was better to make it clear at the beginning that the country's scientific research strength has been engaged in research and manufacturing in related aspects. What's more, Liu Shiqing also has the purpose of borrowing the strength of the state and the military to startle the snake. After scaring the two snakes of Europe and the United States out, he still needs the state and the military to help him shelter from the wind and rain.

"The space telescope I designed, called clairvoyance, has a primary mirror aperture of 8.6 meters, equipped with more than a dozen professional equipment such as high-sensitivity infrared sensors and spectrometers, and will be the largest, most complete and most technologically advanced space telescope in human history. It is designed to have a service life of 15 years, and if it can be serviced and maintained in time, I think it should not be a problem to use it for 20 years. Liu Shiqing briefly introduced the performance of the clairvoyant space telescope, and at the same time distributed some information to Lu Yongxiang, Ye Qiuyan, Hong Dalei and Bi Quanshui.

……

Liu Shiqing spent more than an hour introducing his clairvoyant space telescope, talking about dry mouth and falling sky. What surprised him a little was that Hong Dalei, Bi Quanshui and other four people, after he said for a long time, none of them said anything.

"I said, guys, can you please not look at me like that? I panicked. Do you want to take a stand? Liu Shiqing said a little depressed.

Hong Dalei looked at Lu Yongxiang, "Dean Lu, you are the head of our country's scientific research and academic circles, can you tell me your opinion first?" ”

Lu Yongxiang nodded, "Since General Hong has named him, then I will say a few words." Mr. Liu, let's not talk about whether the technology involved in the clairvoyant space telescope is mature, even if it is a very mature technology. Have you calculated its manufacturing cycle and overall cost?

The Hubble Space Telescope, launched in 1990, cost $3 billion under the price conditions at the time, and its successor, the Webb Space Telescope, cost about $4.6 billion, which is about half of the Hubble Space Telescope after deducting inflation.

The clairvoyant space telescope you are talking about now is larger than the Webb Space Telescope with the primary mirror aperture, and the equipment it carries is much more than the Webb Space Telescope, even if the cost of our China is lower than that of the United States, I estimate that it will cost about 20 billion Chinese dollars to build the clairvoyant space telescope alone. And that's just the cost of the clairvoyant space telescope, not counting anything else.

Now, let's calculate other accounts, the clairvoyant space telescope is so large, using today's Long March series rockets, there is definitely no way to launch the claireye space telescope, the reason is very simple, our country's rockets are relatively slim, the waist is relatively thin, not as thick as the rockets of Europe, the United States, Russia and other countries and regions, even barely used to launch the clairvoyant space telescope, can not do. It was necessary to work on a new model of rocket. Again, the investment in this area is a very large number.

Under normal circumstances, our rockets are built in Yanjing, and then transported by train to the satellite launch center, assembled and launched. From Yanjing to the satellite launch center, the train needs to pass through a lot of tunnels, the cross-section of these tunnels is limited, and few can reach a diameter of more than 8.6 meters.

And transported by plane. The stability of the aircraft cannot be guaranteed, and once it encounters atmospheric turbulence and the aircraft is turbulent, it may cause damage to the rocket. Besides, there is no place to find an aircraft with such a large diameter. The European's Airbus A380 has a maximum diameter of just over seven meters, which is quite different from the 8.6 primary mirror aperture of the clairvoyant space telescope.

If we abandon the existing means and choose to build rockets in the satellite launch center, and there is no equipment for this in the local area, we need to remove the equipment from Yanjing, where to transport it, or buy a new one.

Mr. Liu, so many problems, not only cost a lot, but also need to solve a lot of practical difficulties that make people scratch their heads, is it appropriate for us to build such a large space telescope? I hope you will think about this question carefully.

Of course, I am not against the construction of space telescopes, I think it is still necessary for us to make achievements in this regard, my opinion is that we can build some small-aperture space telescopes, one meter or less, or one or two meters, two or three meters, it is enough, it is enough to meet our needs in many aspects. If one is not enough, let's build two or three. Mr. Liu, what do you think? ”

Lu Yongxiang's meaning is very clear, that is, he is not optimistic about the clairvoyant space telescope plan proposed by Liu Shiqing, in his opinion, this thing is a bit unrealistic and flashy.

Lu Yongxiang's speech undoubtedly set a tone for the speeches of the four of them, and then Hong Dalei, Ye Qiuyan and Bi Quanshui all expressed their attitudes, and they were not willing to let Liu Shiqing build a clairvoyant space telescope, for reasons similar to Lu Yongxiang, they were all very basic and practical problems.

Liu Shiqing smiled faintly. "What you said is very reasonable, if it was a few years ago, I don't need you to say, I wouldn't think about building any space telescope, on the one hand, I don't have that technical level, on the other hand, I don't have the financial strength, of course, the main thing is like Dean Lu said, the actual conditions do not allow, there are too many restrictions. But ladies and gentlemen, it's not like it was a few years ago, and it's not like there's no way to solve the problem you're talking about. ”
