How things work in space while flying
About whom take into space, weightlessness and euphoria about how scary to walk into a dark abyss, spoke about his work cosmonaut Cosmonaut Training Center. Yuri Gagarin Air Force Colonel Valery Tokarev.
About fear I would not say that there is terrible. You are a professional and adaptirueshsya to work, so you have time to think about fear. I was not afraid at the start or on the descent - we also constantly recorded and heart rate, and blood pressure. At the station at all after a while you feel like home. But there is a delicate moment when you have to go into space. Downright do not want to go there. This is the first parachute jump. That's before you an open door, and height of 800 meters. While sitting on the plane and under you like some firmament - not scary. And then it is necessary to step into the void. Defeat a human nature, the instinct of self-preservation. The same feeling, only much more powerful when you go into space. Before leaving you wear the suit in the airlock was depressurized, but were still inside the station, which flies at a speed of 28,000 kilometers per hour in the orbit, but it's your house . And then you open the door - open your hand - and there is darkness, the abyss. When you're on the shady side, you can not see anything under them. And you know that hundreds of kilometers beneath the abyss of darkness, and the darkness of you lived-lit station should go where there is nothing. Moreover you in the suit, which is not a business suit, it is inconvenient. He's tough, and this rigidity should be overcome physically. Only move on the hands, feet hanging ballast. Besides deteriorating visibility. And you need to move along the station. And you realize that if unhooked, then death is imminent. Enough for two centimeters to miss, you can not have enough of one millimeter - and will forever drifting away from the station and push-then it is not that, and you have no help. Yet even get used to it. When comes up on the sunny side, it becomes clear the planet, Blue Earth native, becoming calmer, she let you in thousands of kilometers.
The fact which take into astronauts Spaceman, anyone can become a citizen of Russia, appropriate to specific requirements.This is only the first, Gagarin, the set was of military pilots, and then began to take more and engineers, and members of other professions. Now the application can be submitted to the astronauts, with any higher education, though philological. And then people are selected according to: check the health, conduct psychological tests ... In the last set, for example, only one pilot.But eventually fly space not all, according to statistics about 40-50% of those who received training. Candidate constantly prepared, but not the fact that in the end will take flight. Minimal training - five years: half the total space training, then a half years training in the group - this is not a crew and a half years training in a carriage, which will fly. But on average, before the first flight takes much more time - someone ten years, and someone even longer. So young and unmarried astronauts are rare. In a training center for people usually come at the age of about 30, usually married. Cosmonaut should explore the International Space Station, ship, flight dynamics, theory of flight ballistics ... Our goal at the orbit is also included to shoot, edit and send to Earth stories from the station. So astronauts learn and camera work. And, of course, the requirements for physical fitness constant, as in athletes. About Health We joke that the astronauts selected for health, and then ask how to smart. Health problem is not even to survive the overload, it is not as difficult as one might think, now even untrained people fly into space as tourists. But tourists still fly for a week and a professional cosmonaut spends many months in orbit. And we are working there. This tourist takeoff strapped to a chair - and all his goal - to survive. And the astronaut must work in spite of Overload and maintain communication with the Earth, and be ready to take control in the event of failure - in general, should control everything. Medical selection cosmonauts now, as before, is very complicated. We passed it in the Seventh Air Force hospital scientific test in Sokolniki, and called the place "the Gestapo." Because there through you scan, make something to drink, something prick, pull up something.Then it was fashionable to remove tonsils, say. They have not hurt me at all, but I was told that we should cut. And when you go through screening, doctors contradict our own peril. Then I look further: "And let you remove a tooth?" - and he was a radical, only the nerve removed from there! And the doctors felt that the space may ache, and pulled out. This is the only tooth that ripped me for a lifetime. Though some had much worse. Many pilots were afraid to go to the astronauts, because many of them are written off after medical examination with flight operations. That is you and do not fly into space, and on the plane you fly ban.
On the first flight you to him for a long time to cook, you're a professional, all you can, but you never really did not feel a sense of weightlessness. Everything happens very quickly: pre-flight excitement, then a strong vibration, acceleration, handling and then - again! You're in space. Engines off - and silence. And while the entire crew floats, so you buckled up, but the body has obezvesheno. Here then comes a feeling of euphoria. Outside - the brightest paints. In space, no half-tones, there are all rich, very contrast. Just want everyone to feel, to be twisted in the air, to succumb to the feeling of joy, but when you're a member of the crew in the first place to work. A lot of things happening at once: it is necessary to ensure that as disclosed antenna, check for leaks and so on. And only after you are sure that everything is in order, you can remove the suit and truly enjoy weightlessness - tumble. Again, tumble dangerous. Remember experienced astronauts began to move very smoothly, and we novices spinning-spun. And then the vestibular apparatus is crazy. And you realize that you need to be careful with them because they can begin nausea. About smells in the world is you got to the toilet, and even if does not run - do not worry. And there, if missed, it will all be flying within the atmosphere. And it will be necessary to collect a special vacuum cleaner. But the smells cleaner will not collect. And the atmosphere alone, and it spoils. Smells station continuously accumulate, so that when you first arrive there, you feel not very comfortable. We're there and engage in sports, and the window will not open, not ventilated. But people accustomed to odors very quickly. So you can not say that all the time in orbit you feel discomfort. Only the first time, when you open the hatch of the ship and swam to the station. Although a few months ago with the start time before docking was 34 hours, so that the atmosphere on the ship itself had time to fill with different smells and felt no particular difference. It is now flying a total of six hours, so that the ship remains more or less fresh air. About weightlessness difficult first days of sleep: the head does not feel any support, it is very unusual. Some head to tie a sleeping bag. No you can not leave things loose: fly away. But a week later you are completely accustomed to weightlessness and live in normal mode, generated schedule: how to sleep, when to eat.Nogami in weightlessness you do not use at all, some muscle atrophy, despite the fact that every day you train on special simulators. Therefore, the return to Earth is much harder than fly, overload transferred harder. And then the first time in the world you still can not get used, it is necessary to carry the weight of his body. There's also a finger pushed - flew. Transfer items do not need a friend, threw a thing - he flew. What some have sinned after six months spent in space? Feast, someone asked me to tell something, glass, for example. Well cosmonaut and throws a glass across the table.
