In the past century, with the rapid development of science and technology, mankind has created many high-tech products, such as high-speed rail, aircraft, aircraft carriers, missiles, satellites, etc. These all represent the strength of a country's comprehensive strength. Human development and exploration are endless. For more than half a century, human beings are no longer satisfied with studying things on the earth. They have begun to conduct scientific explorations of outer space, establishing space stations, , space orbital stations, experimental stations, etc. These research activities have given humans more opportunities to understand space.
Human beings have simply wanted to explore space, but now many people yearn for space tourism and regard this as their greatest ideal in life. Dreams are great, but you must consider them based on your own circumstances. After all, the risks in outer space are huge and full of unknowns. Many people have gone there and never come back. According to statistics, more than 30 countries have reached space, and more than 400 people have stepped into space. Among them, there are some people who sleep in space forever and never come back.
We all know that training an astronaut is not easy. He must not only have a good body, but also have strong psychological quality and excellent professional knowledge. Don’t forget that outer space is very easy to enter. Whenever astronauts enter space, they are prepared to sacrifice in space and not return to earth, because everything in outer space is unknown. And even if you don't die in space, you may have an accident while returning to Earth. These situations are all possible, so astronauts are really a high-risk profession.
Since 1957, the former Soviet Union sent the first artificial satellite into space, which kicked off the aviation age. Then the United States was not to be outdone. The United States and the Soviet Union launched a vigorous space race , constantly sending astronauts into space. Until 1975, there were 18 astronauts from the United States and the Soviet Union sleeping in space forever, and one of them had drifted to Pluto and was about to fly out of the solar system. This person is an astronomer from the United States named William Tombaugh. He discovered the existence of Pluto in 1930.
In 1997, Tombaugh passed away in New York. During his lifetime, he had a wish, that is, he hoped that after his death, he could be with the stars and the sea forever. In order to fulfill this wish, in 2006, NASA's New Horizons spacecraft began its journey to Pluto, and they also brought Tombaugh's ashes with them. More than 20 years later, US experts have tracked and found that Tang Bo's ashes have been floating and have reached Pluto, with no intention of stopping. They expect to fly out of the solar system in 2029.
Whether they are astronomical scientists or astronauts, they have all paid a lot to explore the mysteries of space. As for the mention of space tourism, it may appear in the next few hundred years, but humans still have to respect nature and not over-exploit. Everything has its own laws.
