781 Center Director's Office.

Su Yichen sat on the sofa and looked at a copy of the text handed over by Tian Lao. As soon as he rushed back to the capital from the northwest, he was taken back to the 781 center as soon as he got off the plane, and even Luo Yan went directly to Tian Lao before he had time to see him.

A space station, also known as a space station, space station or orbital station, is a manned spacecraft that operates in low earth orbit for a long time and can be used by multiple astronauts to visit, work and live for a long time.

The concept of the space station came from an article published in the Atlantic Monthly in 1869, and in 1929, a book called "The Problem of Space Travel" was published, which put forward a bold idea for the idea of a space station.

In 1969, when the U.S. Apollo 11 was the first to land on the moon, the Soviet Union's space race to the moon fell short with the United States, thus turning its main goal to other aspects to demonstrate the Soviet Union's space capabilities, and this main goal was the space station

In 1971, the Soviet Union launched Salyut 1 was the first space station of mankind, and the most famous space station is the Soviet Union launched in 1986 Mir space station, Mir space station from 1986 successfully launched, has been in service until 2001, more than ten years, astronauts from many countries have visited this famous space station. Following the Mir space station, the first component of the ISS was successfully launched in 1998 and began operation.

In 2011, China launched its first small space station, Tiangong-1, becoming the third country after the United States and Russia to launch a space station independently. According to the plan, China will successively dock with the Shenzhou 8, Shenzhou 9, Shenzhou 10 spacecraft and Tiangong-1, so as to combine to build a complete space station and space room.

And now, the article in Su Yichen's hand is the US space station plan, looking at this plan. Su Yichen couldn't help frowning slightly, he didn't understand that Tian Lao was so anxious to get himself back for this joint space structure space station plan?

Although Su Yichen is not a professional in astronomy and astronautics, he still has some understanding of this aspect due to his work. The U.S. side of the joint space structure space station project was proposed several years ago, and according to the design, the new space station will be mushroom-shaped and will rotate around a vertical axis. It rotates 4.22 times per minute to create artificial gravity. The space-mushroom-shaped space station, which is expected to cost $300 billion and has a structure of 100 meters in diameter and about 400 meters long, is already underway, making it the largest space station program to date.

"What's wrong with that?" Su Yichen asked with some incomprehension, he couldn't see anything wrong with the space station project that had already begun.

"The time is not right!"

"When?"

Hearing Tian Lao's answer, Su Yichen asked incomprehensibly, and Tian Lao revealed the mystery. According to the original joint space structure space station plan, it will take up to 30 years for the entire space station to be completed, but not long ago, news from special sources confirmed that the United States is speeding up the construction of space mushrooms, and the United States will shorten the construction time from 30 years to 5 years or even shorter.

"Five years?" Su Yichen asked a little incredulously, and saw that Tian Lao nodded heavily. He couldn't help but ponder silently. Although we don't know the core of the technology of the space station with the joint space structure, it is a huge project to complete a complete space from construction to completion. What's more, the structure of the entire space station, including the extremely complex components, plus the energy and power of the space station and the configuration of each room, etc., how can it be possible in just 5 years?

Unless the Americans build only the outline of a space station in 5 years, and then do some preliminary configuration, this may be so-so. But the space station will certainly not meet the needs of the original plan.

"Wait! Contour? Energy? Preliminary configuration? ”

Su Yichen's eyes suddenly lit up, he thought of a possibility, if this is the possibility, then it is not impossible for the joint space structure space station to be completed within 5 years.

"Controlled thermonuclear fusion!"

Su Yichen and Tian Lao said this answer at the same time, although they had expected it a long time ago. But when it was determined that the Americans had also mastered the technology of controlled thermonuclear fusion, both Tian Lao and Su Yichen felt a little heavy in their hearts. And more importantly, the Americans suddenly accelerated the construction of the joint space structure space is definitely not as simple as it seems, Su Yichen instantly thought of the Pluto base, if the United States is using the guise of the joint space structure space station to build a spaceship, it is equivalent to a dark Chen Cang in the Ming Xiu plank road.

The more I thought about it, the more I felt that this was a big possibility. Under the guise of a joint space structure space station, it is actually the actual construction of a huge spaceship close to Earth, and then the use of controlled thermonuclear fusion as the power engine .......

Su Yichen put forward his judgment, Tian Lao was not surprised by this judgment, in fact, after getting the news, the intelligence department also made a detailed analysis of this, and the conclusion he reached was roughly equivalent to Su Yichen's judgment. This is also the main reason why Tian Lao deliberately called Su Yichen back from the northwest in a hurry, because judging from the current situation, the Americans are already preparing for the plan to land on Pluto.

Tian Lao asked about the progress of Su Yichen's alpha plan. Although Tian Lao did not directly state the reason why he asked this question, Su Yichen knew very well in his heart that Tian Lao's inquiry was of course aimed at the plan that the United States had already launched.

The Alpha Project is proceeding fairly smoothly, and the miniaturization, simplification, and safety of the controllable thermonuclear fusion device are proceeding step by step, and according to Su Yichen's plan, it can be completed in about two or three years, but if it is to fully reach the point of using the spacecraft engine, I am afraid it is not so easy. From this point of view alone, it will take at least seven to ten years for the entire Alpha project to be completed.

"Maybe we can learn from the Americans." Seeing the disappointment on Tian Lao's face, Su Yichen thought for a while.

"How?"

Pointing to the text he had read before, Su Yichen said: "If I guess correctly, the reason why the Americans do this is actually to avoid the instability of the controllable thermonuclear fusion engine in the case of spacecraft launch, and they use the space station project to carry out spacecraft assembly in low-earth orbit, avoiding various problems caused by environmental changes such as gravity, vibration, friction, and temperature from the earth, which is very desirable." ”

"You mean to say that we also learn from the Americans using the way the space station was built to complete the Alpha program?" Tian Lao frowned and asked, but before Su Yichen could answer, he shook his head first: "This is unlikely, compared with the developed United States, we are much behind in space construction, and the advantages of the United States in the International Space Station are incomparable to us, and we can't hide it from the Americans by using the space station as a cover to build a spaceship, once they detect ......it, we can't hide it." ”

Tian Lao didn't say any more, but Su Yichen already understood what he meant. But the problem is that if you don't learn from the Americans to build a spacecraft in low earth orbit, then it may be difficult for the Alpha plan to be completed ahead of schedule, and now, the United States has chosen a shortcut, but Su Yichen has to catch up with the other party's footsteps step by step, and it is extremely difficult to compare the two.

"Aside from this, do you have any other ways to speed up the plan?" Tian Lao asked with some anxiety: Once the United States takes the lead, what the consequences will be can be imagined. In any case, China must complete the Alpha program before the United States and launch a spacecraft capable of space travel.

Su Yichen couldn't help but smile bitterly, science is in order, although he knows the theory and direction, but it is simply whimsical to complete the alpha plan in such a short time. But the current situation is also very serious, the American side has already gone ahead of them, and even if the Alpha program is completed by then, maybe the American spacecraft will be completed in low-earth orbit by then.

"There's another way." Su Yichen pondered for a long time and finally spoke, but in Tian Lao's eager gaze, Su Yichen said with a wry smile: "But this method is risky, maybe the superiors will not agree." (To be continued......)
