Many countries have implemented plans to explore space, and many of these great astronauts and scientists have made indelible contributions. But people’s knowledge is still very limited. Where is the boundary of the solar system? So far we have no way to figure it out.
On October 4, 1957, the Soviet Union successfully launched the first artificial satellite Sputnik 1, and this achievement made the United States like a thorn in its back. After that, in October 1958, NASA approved the Mercury manned spacecraft. As of April 25, 1961, the United States conducted seven unmanned spacecraft test flights.
Faced with this situation, the Soviet Union was naturally unwilling to show weakness. Vostok 1 was launched on April 12 of the same year. At that time, astronaut Yuri Gagarin successfully returned after orbiting the earth. This was an important progress in the history of human spaceflight. Until now, many countries have had astronauts in space, but you must know that space exploration itself is full of unknowns and dangers. Many of them return to the ground smoothly, but some unfortunately stay in space forever.
Soyuz 11 of the Soviet Union had an accident on its way back to Earth. At that time, the three astronauts were afraid that the three astronauts, Chayev, Volkov, and Dopolowski, were already in the process of carrying out the mission. Stayed in space for 24 days. But when preparing to return to Earth, the huge pressure at this time shook the pressure valve, causing the oxygen in the return cabin to leak, and the pressure in the cabin was rapidly reduced. Due to the unreasonable space design, three people could only take off the spacesuits, but this The action made them die of acute hypoxia, boiled body fluids, and they have been sleeping in space ever since!
However, there is such a person who also sleeps in space, but he flew past Pluto and is about to float out of the solar system. He is Clyde William Tombaugh. This person is known as the “son of astronomy” because he grew up. He loves astronomy very much, and made his own astronomical telescope, and when he was 24 years old, he discovered Pluto based on the predictions of other astronomers. Pluto is a cold and dark planet. There is a dead silence on the planet. People think it is very similar to the underworld in the imagination. They gave it such a name. However, after Tombaugh passed away in 1997, in order to commemorate him, people gave him his Part of the ashes were taken to Pluto on NASA’s New Horizons probe! Now that this probe has slowly started to fly out of the solar system, Tombaugh is also known as the “farthest space tourist” in the history of human spaceflight.
In any case, these people have made great contributions to the aerospace industry and deserve our admiration. People have such a strong desire to explore, and one day they believe they will explore more of the mysteries of the universe, and hope that they will be able to master higher technology at that time, so that the danger of space missions can also be reduced. Despite facing so many sacrifices, this road is never-ending. What we can do is to remember these people who made outstanding contributions with awe.
