There are five “remains” floating in space, each of which has made contributions to human beings and deserves respect

Since mankind entered the road of scientific and technological development, it is no longer a dream to go out of the earth and explore the universe. Human beings soon realized the dream of flying into space and entered the era of space exploration.

With the advent of the era of space exploration, 360 lines have another occupation, that is, astronaut. This is not only the greatest occupation of human space exploration, but also a very dangerous occupation. For human beings, space is a strange and unknown place. The vacuum environment, coupled with the ubiquitous cosmic radiation, and other kinds of unknown risks.

Astronauts are a great and respected profession. With human expectation and interest in space, they enter the unknown, mysterious and dangerous space. Of course, it’s not easy to become an astronaut. It requires very strong physical quality and good psychological quality. Therefore, the selection of astronauts is generally carried out in flight.

In the course of space exploration, human beings are bound to experience a lot of hardships and hardships. Many people have made their own contributions to the cause of space exploration, and many people have given their lives to the cause of space exploration. In more than half a century of human space exploration, a total of 18 astronauts have given their lives. Among them, the “remains” of three astronauts were left in space, while the other two “remains” were floating in space.

Each of the five “remains” floating in space is worthy of our respect and has made great contributions to the human space cause. Some of them are left in space by accident, and some of them are looking into space and volunteering to wander in space after their death. So who are the five “remains” in space?

The first one is Eugene shumek, a name that many people may be very unfamiliar with. It is the only earthman buried on the moon in human history. On April 28, 1928, 90 years ago today, Eugene shoemaker was born in Los Angeles, California. He is a great astronomer and one of the pioneers and founders of planetary science.

Eugene shoemaker and two other geologists discovered the natural coesite, which was published in the journal Science in 1960. This discovery became one of the important evidences that balinger crater was more likely to be formed by meteorite impact.

In memory of Eugene shoemaker, Australia’s shoemaker crater, asteroid shoemaker, and NASA’s rendezvous shoemaker spacecraft launched in 1996 are all named after him.

Eugene is very fascinated with the moon and has been devoted to studying the mystery of the moon. Although he is a geologist, he tells people with his own actions and achievements that exploring the moon is not only the work of astronauts and astronomers, geologists can better uncover the mystery of the surface of the sky. He hopes to become an astronaut one day, a land to set foot on the moon and conduct geological investigation on the moon.

Eugene has done four things for his dream of the moon. First, he creatively studied the stratigraphic structure of the moon with geological theories and methods. Through the photos of the lunar surface taken by telescopes, he analyzed the formation time of the strata of the Copernicus crater on the moon, drew a detailed geological map, and reconstructed the geological history of the lunar surface.

Second, he founded the astrogeology Science Center at the U.S. Geological Survey (USGS) and was appointed head of the center

I’m a scientist. Since then, USGS is no longer limited to the earth, but covers the geological research and mapping of all solid objects in the entire solar system. This institution is still one of the most important and active structures in the field of planetary geology.

Third, he was deeply involved in two early NASA lunar exploration projects: Ranger and surveyor. It was a time when man knew little about the details of the moon’s surface. Fourth, he was deeply involved in NASA’s Apollo moon landing program and was responsible for training Apollo astronauts. Originally, Eugene himself had a chance to land on the moon, but this dream was broken in 1963: Eugene was diagnosed with Addison’s disease, which can affect the motor function of patients.

What Eugene has done has made geology an indispensable and important discipline in planetary exploration, and has enabled NASA and USGS to establish a close cooperative relationship since then. In memory of Eugene’s contribution to human lunar exploration, NASA launched the lunar explorer probe on January 7, 1998, which brought some of Eugene’s ashes to the moon. A part of Eugene’s ashes are buried in the south pole of the moon forever, integrating with the land of the moon.

The second is an astronomer named TOMBO, who discovered the dwarf planet Pluto. You know, decades ago, human space exploration was just making progress. At that time, it was very difficult to find objects on the edge of the space system. According to other astronomers’ predictions, Thompson discovered Pluto in 1930. At that time, it was a big event in astronomy.

To commemorate his achievements, after his death, part of his ashes was sent to space by NASA’s new horizon to float. It became the second “remains” left in space.

The other three “remains” are three astronauts from the former Soviet Union. After 23 days in space, the former Soviet Union “union 11” was ready to return to earth. When it returned, the air exchange valve connecting the orbital module and the return module was opened, resulting in the air leakage and sudden change of pressure in the return module. In just 40 seconds, three astronauts died of acute hypoxia and fluid boiling.

It can be seen from this that space is such a dangerous environment that even a little malfunction may cause serious consequences. With the continuous progress of human space science and technology, the future spacecraft will be more and more advanced, and the requirements for all aspects of the quality of astronauts will continue to reduce. Especially in the aspect of physical fitness, if modern space technology wants to go into space, it first needs a very high-quality physical fitness.

But in the future, it will be as convenient and easy for people to go out and take a car. Most people hope to go to space exploration and travel. At that time, mankind will be entering the era of comprehensive space exploration, space mining, space exploration will become a fashion, and countless people will go into space exploration. Although space technology will be more and more developed and more people will go into space, the risk of space will not be reduced. Moreover, when we go out of the solar system, we may really experience space adventure, and more people may have to pay for their lives.

In fact, the whole history of human civilization is a history of constant efforts made by our ancestors. Without the efforts of our ancestors, there will be no modern peaceful and developed human civilization. Similarly, if we want to have a better space age in the future, we also need the space exploration efforts of our generation.
