So far, three astronauts have been buried in space. Only who has floated out of Pluto and is about to fly out of the solar system?

Humans have been particularly interested in the starry sky overhead since ancient times. For example, in ancient China, many great politicians and writers thought and explored the starry sky. For example, Qu Yuan questioned the birth of everything in the world and wrote in his famous Tian Wen in a very beautiful poetic form:

The top and bottom are shapeless, how to test them? It's dark, but who can do it?

Feng Yi just likes it. How would he know? Obviously secretly, but when?

The combination of yin and yang, what is this? Hey, it's nine times. Which one is it?

But what did you do? Who did it first? What is the relationship between dimension and celestial pole? ?

What is even more incredible is that in the Han Dynasty, great scientists in ancient China discovered that the moon could not shine, but it seemed to shine when it was irradiated by the sun. Zhang Heng wrote in the book Ling County:

The sun is like fire, the moon is like water, the fire is light, and the water contains scenery. Therefore, the moonlight was born in the sun, and the spirit was born in the sun. On that day, the light was full, and on that day, the light was exhausted. The stars are shining, because water becomes light. During the day's rush, the light is often inconsistent and hangs over him. It means dark and empty. When the stars are dark, the moon will eat. It's getting thinner and brighter. See the light in the dark, and the light is unyielding, like hope. Fang is in the sky, and heaven and earth are the same. I expect darkness, and darkness has been taken away from me, so I hope it is like water. The fire glows at night and is unknown during the day. The moon is at night, but it is the same as the day. Stars are not, and so are strong and weak.

This shows that in a very early time, China's astronomical science and technology has developed quite advanced. However, due to historical reasons, China's science and technology began to lag behind the world after the Ming Dynasty. Closed to the outside world? Situation. Westerners, on the other hand, took over the banner of exploring the universe and astronomy and began to explore higher and farther places. Since Copernicus, who was born in 1473 (Ming Dynasty in China), proposed Heliocentrism, the astronomy of westerners gradually rose.

After the mathematical principle of Newton's natural philosophy appeared, people became more aware of the relationship between force and motion, thus promoting the development of human dynamic system. Later, the appearance of Pelant, Einstein, Schrodinger and others further accelerated the speed of human beings in the journey of science and technology. Therefore, on April 196 1, Soviet astronaut Gagarin was launched as the first astronaut to fly into space on the Dongfang 1 carrier rocket.

Gagarin, who started from Baikonur launch site, flew to the orbit with the highest altitude of 30 1 km above the ground. After circling the earth, Gagarin returned to the earth. This is the first time that mankind created the world, and it has been 59 years since today. The flying of the Soviet Union also stimulated Americans, and later the United States began to hold flying activities on a large scale. Other countries have also launched their own? Pray for heaven? It is planned to send astronauts into space one by one.

So far, humans have sent more than 500 astronauts into space, but not all of them have returned safely. The environment in which the spacecraft operates is very bad, lacking oxygen, with large temperature difference, and it may encounter various unexpected situations. Therefore, 18 astronauts gave their lives for the human space exploration program. But most of them encountered accidents during the take-off or return of the spacecraft, and only three astronauts took themselves? Stay? In the universe.

The three astronauts buried in space are all Soviet astronauts. They have completed the space mission safely, but when they are ready to go home, a fatal problem appears. It turned out that they took off their spacesuits after returning to the spacecraft from space, but at this time the oxygen of the spacecraft leaked because of the air leakage of the valve. Three astronauts suffocated in the spaceship and stayed in space forever.

But in addition to these three astronauts, one person has drifted directly to Pluto and is about to fly out of the solar system. Who is he? This man's name is Clyde? William? Maybe everyone is not very clear about this long name, but if you tell everyone that he is the discoverer of Pluto and other 14 asteroids, then everyone will know his position in modern astronomy.

At the beginning of the 20th century, many people speculated that there was another planet in the solar system, because the orbits of Uranus and Neptune calculated by mechanics were obviously different. Clyde discovered Pluto for the first time in 1930 by comparing photos of the starry sky. This caused a great sensation at that time. Because of his talent in astronomy, Clyde, who was born in 1906, was soon employed as a staff member of Lawwill Observatory in Arizona.

Clyde, who contributed his whole life to the development of human astronomy, left a last wish after his death and sent his ashes to Pluto as much as possible. So on June 6, 2006, in 65438+, the United States took away some of Clyde's ashes when it launched the New Horizons to explore Pluto and other nearby satellites. 15 At 7: 49 on July, New Vision passed Pluto with Clyde's ashes, giving Clyde a chance after his death? Do you see it? Pluto.

Then New Horizon began to fly out of the solar system with Clyde's ashes. In fact, it is hard for us to imagine what will happen to Clyde's ashes. Will he be a technologically advanced alien like Yun Tian Ming in "Three-body"? Resurrected? And be number one? Immigrants? Humans in outer space? Or will he witness an epic cosmic war like that in Three-body?

Nowadays, the scientific and technological level of China people has also begun to improve. Our? Candlestick? We are also heading for Mars. I hope our country can take over the task of space exploration completely in the future. Do it. Above, he looks for the green void, below, the yellow spring? Explore the endless world of science!
