Soon after, the country that sent him to heaven was gone, so he stayed in space for 311 days

A large number of studies have shown that in the long-term weightlessness environment, all organs of the body will undergo significant changes, even the structure of the brain will change. Although these changes will gradually recover after returning to the ground for a few months, if the time is too long, this change is likely to become irreversible, so the human astronauts can not be long To stay in space for work. < / P > < p > so how long have the astronauts who have been working in space for the longest time so far? He stayed 340 days, a record held by NASA astronaut Scott Kelly. Before that, former Soviet astronaut Sergey konstandinovich krikalev had worked 311 days in space, and he was the record holder for the longest time in space, with 803 working days in space in his entire career The 311 day extra long space mission was dramatic. In April 1991, Sergei, his colleague Anatole and British chemist Helen took off to the Mir space station. At this time, Sergey did not think that a long journey would be waiting for him. When he returned to earth again, everything had changed. The Mir space station is an orbital space station built by the former Soviet Union, and is also the first space research center that can live for a long time in human history. The purpose of Sergei’s trip is to take over the astronauts from the previous mission to carry out the maintenance work of the space station. Eight days after Sergey arrived at Mir, the astronauts of the previous mission returned to earth with the British chemist Helen. Only Sergey and Anatole remained. According to the plan, they will work here for five months, waiting for the next batch of astronauts to take over their work. However, after five months, new astronauts did not arrive. However, they have been in space for too long. If they continue to do so, they will undoubtedly cause great damage to their health. When forced to do so, Sergei’s colleague Anatole was taken away, leaving Sergei alone to continue the maintenance of the space station. < / P > < p > Why didn’t we find an astronaut to replace Sergei as scheduled? At this time, the Soviet Union did not care about this. The crowds of people, the procession, the troops maintaining stability and even the tanks had filled the streets of Moscow. As a result, Sergei began to wait day after day on the Mir space station. However, he did not wait to replace his astronauts. What he had to wait for was more and more problems. At first, it was only a matter of human beings, but soon it became a matter of money. Without money, naturally, there was no way to take Sergey back home. It is said that during Sergei’s stay in the space station, the United States also sent a transport spacecraft to the Mir space station to replenish Sergei’s supplies. Whether it is true or not remains to be discussed, because there seems to be no spacecraft that can dock with the Soviet Union at the same time. Although trapped in space, Sergei firmly believed that his motherland would take him back to China. Until December 25, 1991, the Soviet Union disintegrated, and the countries that sent him to heaven no longer existed. Instead, 15 countries were separated. In a sense, Sergei became the only “Soviet” in the world. < / P > < p > now, it is not only a matter of people and money to take Sergei back home, because the Baikonur space launch base used by the former Soviet Union to launch rockets no longer belongs to Russia. It is in the territory of the split Kazakhstan. Can Russia use it? Of course, you can pay, and the problem is that you don’t have money. After repeated negotiations, Russia finally agreed to let the first Kazakh astronaut fly off to offset part of the cost of using the launch site. Finally, on March 25, 1992, Sergei waited for his replacement after 311 days in space, and he was able to return to earth successfully. When Sergei came out of the capsule with the armband of the Soviet Union still on his spacesuit, the country no longer exists, and Sergei’s heart may be as lonely as he was in space. During the 311 days of his stay in space, Sergey faced not only loneliness, but also great risks. Long stay in space made his muscles atrophy and his body gradually weakened, but he did not return to the space without permission. Yes, if Sergei wants to come back, he can do it, because the Mir space station carries a return capsule, but if he returns without waiting for a replacement, the Mir space station will face the fate of being scrapped. In the face of such a choice, Sergey did not hesitate, he stayed. This long space trip was not Sergei’s curtain call. Just two years after his return, he became the first Russian astronaut to fly into space with a NASA shuttle. Straight screen S20! Samsung Galaxy S20 Fe exposure: 1Hz high brush + snapdragon 865
