Chapter 508

Many people saw Ren Hong talking and talking in front of the stage, and their hearts were filled with laughter. At the moment, didymons, the head of Aida who was paying attention to the news, was flushed. It was really unbearable that this incident was mentioned again. The words looked extremely respectful, but actually it was the opposite.

"Sentinel mission" is one of our long-standing space exploration plans Ren Hong said. Then he added: "from the beginning of human aerospace science and technology to today, with the development of space science and technology and space exploration over the past few decades, we know that space is not as peaceful and peaceful as we see. It is difficult to imagine a near time Martian annihilation impact. If the impact target is the earth, it will be a terrible disaster for all mankind."

"With the continuous progress and development of human science and technology, it is more and more clear that the threat of the earth being hit by asteroids can not be ignored. The potholes on the surface of our moon indicate that the beautiful earth will not receive special treatment. It is obviously not enough to rely on the moon as a satellite to protect it."

"In the near world, in the 2013 meteorite fall in Russia, a line of fire across the sky was witnessed by countless monitors and mobile phones. Fortunately, this is a relatively small meteoroid, not an asteroid, but even so, it has caused more than 1200 casualties and tens of millions of dollars in direct economic losses. Fortunately, the falling point is not a metropolis, otherwise the loss will only be more serious! "

"How many potential asteroid threats are there on earth? This map from NASA will be very intuitive." Ren Hong said, gently press the remote control button, the giant screen shows the space orbit of the four earth like planets in the solar system. In addition to the orbits of mercury, Venus, earth and Mars, the weaker lines are densely distributed in the whole space, which is still like a wire mesh. This picture gives people a feeling of intense phobia.

Looking at the picture in the giant screen, Ren Hong said: "the boundless space is so crowded, the orbits of asteroids are crisscross and irregular, and" traffic accidents "that occur in places we can't see in outer space are staged every moment."

Ren Hong looked at everyone and said: "according to the assessment of authoritative astronomical institutions, every 1000 years, an extraterrestrial star with a diameter of about 100 meters will fall to the earth, and a star with a diameter of about 50 meters will hit the earth with enough energy to destroy a super metropolis with a population of 10 million, and an asteroid with a diameter of 10 kilometers will affect the whole earth It's a global disaster. "

"This space orbit simulation map released by NASA shows the orbits of near earth objects larger than 100 meters in diameter in the earth like planet region of the solar system, which shows how lucky our home is to survive. Up to now, Aida has only identified about 30000 large and medium-sized asteroids in the near earth region, but only 3% of the total 1 million

"Aida alone is not enough. It is precisely because of these foreseeable threats that the twin project was born successfully. The sentinel mission of the twin project is to deal with the defense strategy against asteroids that may impact the earth. "

As soon as this was said, the media reporters on the scene were excited. They would not care about the asteroid impact on the earth. They only heard this from Ren Hong's tone of voice Is this the rhythm of fighting against Aida?

Even if it's not the media, it can be rendered yes.

However, the scientific workers who came to the scene were puzzled. Even if one of the world's aviation and aerospace powers is backed up, can your technology company compete with Aida, which is jointly established by aerospace agencies in the western world?

Ren Hong saw that some people turned to him with a look of doubt, but he did not care. Instead, he continued: "the sentinel mission aims to study the threat of asteroids and formulate specific solutions. For example, Skynet, which is made of high-strength materials, captures 100 asteroids with a diameter of about 500 meters, forcing them to change their original orbits, or in asteroids Artificial thrusters are installed on the surface to change their orbit by human means to prevent them from hitting the earth and so on

"For this reason, the project of" Tiangong Que "has been officially established. We will build the largest space station in the history of mankind and send it into outer space. The" heavenly palace "will play an important role in the whole" sentinel mission ". No, to be exact, it will play an important role in the whole Gemini project."

The largest space station in human history? The people on the scene were slightly stunned when they heard Ren Hong's statement. They were questioning them subconsciously when they heard this, but when they looked back, they were not the same. With the abundant funds of matrix technology and the support of the National Aeronautics and Astronautics administration, this space station is really possible to be realized. We should know that the only space station on orbit, Tianzhou, is Chinese, which means that the technology is not a problem Capital is not a problem, so the sum of the two is equal to the possibility.

However, new questions also arise. Why does the "Tianzhou" need extra waste to build "Tiangong"?

"The mission of" space station X "will not be a" Space Center "and" space station "will be a" permanent mission "around the space At the beginning of the palace, the volume of "Tiangong ring rail Xinggang" will exceed 5000 tons5000 tons???

A large number of outsiders, whether scientific workers or journalists from various media and newspapers, were all stunned. They all felt that they had heard the wrong thing, and they were sure it was 500 tons instead of 5000 tons? Even a 500 ton space station is enough to shock the world. 5000 tons, which is equivalent to the volume of ten retired international space stations, is also

In fact, strictly speaking, there is no final data on the volume of "Tiangong", because according to Ren Hong's assumption, the ring orbit star port will become larger and larger, and he also conceals some data. The completion of the first phase will be 7700 tons.

Didymons, who is paying close attention to the press conference, stands up subconsciously when he hears these words, and his eyes are full of wonder. He suddenly felt that Aida should not have lost such a powerful role.

Interestingly, no one on the scene questioned whether Tiangong could succeed in technology. China is the only three countries in the world that can independently develop space stations and send them into space. Obviously, this is a matter of technology and capital. It is only a matter of how much money should be invested to determine the size of the "Tiangong".

It's just that many people can't understand what it's for to make such a large ring orbit space station? Is it just noble to block the so-called asteroid from hitting the earth for the benefit of all mankind? I believe it!

It's not time to ask questions. These questions can only be carried in the stomach.
