Comments (0) Category: Personal Diary the successful launch Shenzhou VII for China and the world has a milestone, but also in the aerospace industry in China with Russia and the United States has reduced the gap for some distance.
a person's a small step, one giant leap for mankind. This small step in the sixties of last century had been made, but this step is a new China, it is peaceful, without war haze, no political overtones, this step is a state of mankind's peaceful rise step towards the century.
is happening and we watched a glorious time of impending road look back to human space, the sun shines all the way under the road is not flat, but also heavy rough.
1965, the former Soviet cosmonaut Leonov made the first step in human space travel, human beings in the universe left the glory. US-Soviet Cold War was raging
. Who will be the first step in the realization of mankind in space, a space between the two countries and a focus of competition. For the aviation sector, which is both accountable to the political task of the CPSU Central Committee, is a large country competition.
we all know, a full vacuum in the space environment, astronauts emerged from the capsule to open the door out of moving far from simple. In addition to wear space suits, but also through the airlock (when the astronaut extravehicular transitional role to play.) Former astronaut extravehicular airlock must be conducted on the pressure relief, until the cabin air pressure equilibrium with the EVA to enter the space. The Soviet side was responsible for designers Severin spacewalk equipment presents a scalable solution airlock, it seems both simple and ingenious.
February 1965,
new balance 574, the Soviet team a new experimental spacecraft launch system, so that their dismay, this time with airlock unmanned experimental spacecraft early in the return process started blew the spacecraft in space to be destroyed. Another subsequent test, the results are still frustrating. However, according to intelligence, anxious Americans will soon be implemented lit space walk, and Severin had to bet, the pixels of the Central Committee put forward an early launch Time to be in just one month later.
The mission was selected as two of the astronauts, one is the driver Alexei. Leonov, another is the commander Pavel. Do not Australia Aliyev. Korolev launched the night before (the chief architect of the spacecraft) was filled with gloom. He told Basayev and Leonov not Elijah: they will soon be out of the spacecraft,
Delicious stew noodles - Qzone log, the astronauts attempt to rush into space in front of us. So, we decided God was a great adventure. speech, but I know very well what I'm doing. As an engineer, I fully understand that the world does not exist 100% chance of success. But I am sure we will be able to succeed. The two astronauts certainly know what it all means, they look solemn: Korolyov, or been worried about. Before takeoff, he warned him repeatedly Leonov said: .
as planned, the spacecraft orbit around the first lap, Leonov began the spacewalk preparations. Tied him with the spacecraft attached to a rope chain, 5.35 meters long, containing a telephone line, the aim of maintaining contact with the spacecraft and its own security, to prevent the astronauts from the spaceship. It was not until the second lap, closed cockpit Leonov well in the confirmation only after the doors opened. Had been in a compression state of the air lock as accordion bellows, slowly open and stretch. Do not Elijah Aliyev waving to the Leonov, simply said: When the head, then the entire body. Then waved Leonov became the first person in the vast space walk.
���а�ŵ�� recalled the incident: . I gently push of a hatch, the whole body suddenly the click on the pop-up go completely involuntarily,
new balance shoes, like a cork on a bottle, like out of the hatch.
code-named space. a lot of effort can not grasp the operation of the camera take pictures in space devices.
then there have been newspaper reports that after extravehicular Leonov out and do some action items,
周末，一个人 - Qzone日志, but also Anti several somersault. In fact, the real situation is, when the spacecraft in the rotation, the body also rotates Nothing can get him to grasp,
new balance running shoes, strong and so do not. are as somersaults, in fact beyond their control. Fortunately, Flanagan more than five meters of the rope he wound up,
new balance outlet, wrapped near the hatch, only to stop the rotation.
by the ability of life-support systems, astronauts can support forty-five minutes , Leonov also should do more of this operation, but there was an accident, he arrhythmias, nervous sweat, has not allowed him to continue. only lasted ten minutes of the space walk and had to rush the end.
shack every side with clouds and rain, this time there was another trouble.
when Leonov airlock into the camera, it is always in the gas chamber Air rushed out of the tiny, wafting EVA. toss most of the day, finally put the camera into the cabin, can body stuck in the cabin door, how can not come back.
This is a real danger. As is the vacuum of space, Leonov's spacesuit bulging up, like a ball in general. airlock section in front of only one hundred and twenty centimeters in diameter, while the expansion of the space suit has reached a diameter of hundred and ninety centimeters. Leonov another hard drill several times, still to no avail. At this point, he can not help but exclaimed: No, I'm too late. I can not go back ... ... Do not do anything Australian Aliyev.
the door of life into the gate of hell. After repeated struggles, Leonov has been exhausted. He meant that he may never going ship within, and waiting for him to become a free-floating in space and the body. He caught his breath, felt dizzy, respiratory rate doubled, and increased temperature over the thirty-eight degrees Celsius, heart rate hundred and ninety. Because sweating, covered with a layer mask helmet water vapor, eyes blurred. Also because of wearing a helmet, can not wipe the sweat flow to the eyes, and what could not see. coupled with too much tension, general fatigue , Leonov awareness of a problem. again and again in vain attempts of the survivors he completely lost confidence. is the critical moment, usually repeated training hard boring a role in the occurrence of miraculous. Leonov later recalled said: Somewhere, as if to remind the coach in my ear said: Hi! Young man, space suit at the waist with four button, each button can be released within a quarter of the air space suit. When the space suit pressure is too large, this is the only decompression approach. minutes, but the work of the lighting system had only five minutes. This means that, in the dark state, the Leonov ship will be more difficult to return.
obviously it can only be reduced life support system pressure solution. Leonov began to spacesuit pressure relief, before the most drastic drop twenty-five Pa, the pressure has been less in the permissible limit. spacesuit finally deflated down, reducing the volume. Leonov said afterwards: > The first human spacewalk over ten thousand in the adventure.
they prepare to end the twenty-six hours two minutes of flight, to Earth turning for home, the cabin oxygen pressure within the exception occurs, the temperature dramatically. At this point, the normal procedure they have to quickly lower the temperature, to prevent the ship exploded. But the two astronauts, all operations did not work. they again fall into despair. excessive fatigue when they fall asleep once.
do not know when, do not Elijah Akayev and Leonov was the voice of a class is awakened by an explosion the. two of the first reaction is, the spacecraft is thought the explosion, the ultimate sacrifice moment finally arrived. so that the two astronauts were surprised that the spacecraft does not have any signs of an explosion. and then a closer look, so that they surprised that the cabin oxygen pressure is slowly decreased and gradually returned to normal.
after expert analysis of this strange phenomenon, due to light radiation and heat sink of space's sake , the spacecraft toward the sun side of the temperature reached nearly hundred and thirty degrees,
new balance sneakers, while the back cabin hundred and seventy degrees below zero, the temperature difference between the two sides so that the spacecraft nearly Baidu small deformation occurred. Leonov capsule years later, the door has been deformed left a small gap, making the air inside spacecraft out leakage. the cabin life support system quickly aware of the pressure relief phenomenon, responded immediately to start the booster to improve the cabin oxygen pressure. in the ambient temperature gradually increased, the two astronauts sleep in a floating state. I do not know who inadvertently touched the supplementary air switch, all of a sudden started strong pressure exhaust valve, door followed completely closed.
really Heaven must be a way. Do not Elijah a little sigh of relief Akayev and Leonov began to journey home. worry about the danger is blowing - the onboard autopilot positioning system also malfunctioned.
finally decided to take two astronauts landed manually. but in the end the two pilots of the manual operation is also a mistake, deviation from the intended impact point three thousand two hundred kilometers, and finally fell to the depths of snow-covered forests. dense thick trees and two meters of snow has played a buffer role.
EVA is now under a blizzard, wolves howling in the surrounding constantly. The two astronauts climbed out of the door hard, outdoor survival training in accordance with past procedures,
眼泪知道 - Qzone日志, frame good antenna, sent SOS signal. because they deviate too far, command centers, and they lost contact. the Soviet Union in March was very cold, so they spent a cold night, until the next day to find their recovery over the world who found them in the sky. finally the successful completion of this missions.
first human in space, so in the adventure of life and death intertwined with the accident.
past experience guide for the future Looking back, looking into the future. Our space industry will be better tomorrow!
