Space station, also known as space station, space station, orbital station. Pen~Fun~Ge www.biquge.info is a kind of manned spacecraft that operates in low earth orbit for a long time and can be used by many astronauts for patrolling, long-term work and life. It is like an ordinary satellite, which can constantly sail in outer space for several years, and at the same time, the space station has all the facilities of human life, and can live in space for a long time without returning to Earth.

In later generations, the record holder was Russian cosmonaut Sergei Vasilyevich Avdeyev, who made three space flights. The first time he spent 189 days in space, the second time he spent 178 days in space, and the third time he spent 378 days in space, for a total of 746 days of flight in three times. This is something that the space shuttle can absolutely not reach.

In fact, the space station can be traced back to 1869, when Everetthale wrote an article for The Atlantic about "the moon built of bricks." Since then, Konstantin Tsiolkovsky and Hermann Obert have also envisioned the space station. However, due to the limitations of technology, it was impossible to achieve at the time.

Until the seventies, the Soviet Union lost the space race with the United States to the moon and therefore switched to the space station. Salyut 1 was successfully launched in 1971 and was the first space station in human history. Unfortunately, all three astronauts suffocated and died due to a valve failure on the way back.

After that, the Soviet Union launched a series of space stations, from Salyut 1 to Salyut 7.

And now, Salyut 7 continues to fly in space.

On April 19, 82, Salyut VII was launched into low Earth orbit by a Proton launch vehicle. Historically, the space station was in orbit for a total of 3,214 days, eight years, until 91, when the Soviet Union ceased to exist, before it fell.

And now, Salyut 7, which has just been in operation for a year, is at the peak of its vitality, and this space station has three astronauts on duty at this time, and they have been flying in space for several months.

"Savitskaya, we received an order from the ground to adjust our orbit." On the space station, Commander Kizim said: "We need to rescue two American astronauts who have been shipwrecked in space, and this is a difficult political task. ”

An American astronaut in distress? Hearing this, a smile appeared on Savitskaya's face: "It turned out to be our American counterpart. ”

Among the three cosmonauts, Savitskaya is a woman, and space does not stop women, on the contrary, the unique advantages of women allow them to play to their advantages in space flight missions.

For example, women are more agile than men, and in the docking of spacecraft, Savitskaya performed better than male cosmonauts, and in spacewalks, Savitskaya also scored perfect points in training.

"Savitskaya, you need to operate our space station, Solovyov and I are going to put on spacesuits, maybe, we need to do a spacewalk to be able to fish those two colleagues up, Moscow's order, even if it's a corpse, to fish it up, at least one!"

Savitskaya still had a charming smile on her face: "However, how do we find them? Our radar can't detect astronauts flying in space, right? ”

"According to ground analysis, these two astronauts, when the Challenger had an accident, were outside, dismantling our Polar, so it is likely that they are still with the Polar, as long as we can get close to the Polar, we will be able to find them."

"Understood." Savitskaya said: "Don't worry, our space station will definitely be able to catch up with the Polar and get close to it!" If the Polar is connected again, I can still dock. ”

Kizim nodded: "It's up to you, our space station is much more difficult to operate than the Soyuz spacecraft, you must be careful, don't crash the polar space." ”

The space station, which is flying at a speed of almost eight kilometers per second, is actually very dangerous to get close to the Polar, but now, there is not so much to care about, as soldiers, they need to carry out orders!

Sitting in the control position of the space station, opening the operation interface, she will control the space station with all her might, make many complex orbit changes, and then get close to the orbit of the polar.

Of course, she is not alone, the Baikonur cosmodrome, the survey ships on the ocean, are helping her, this is a big project of the system.

In space, it is extremely dark, and when it comes to the side with the sun, you still can't feel the warmth.

What is it like to be in space, drifting for hours?

Nelson didn't know that he was proud to be an astronaut, and that he was ready to die at any time knowing that it was a dangerous job.

However, when this moment really came, he felt that there was an instinctive call for survival in his heart, he couldn't die, he couldn't die!

It was precisely because of this survival instinct that he kept lying on the Polar, tightly using a tool to hook a position of the Polar that was disassembled, and he was waiting.

What to wait for? In fact, he didn't know, he only knew that he had to stay with the Polar to have any hope of being rescued! In front of his eyes, there was still the last appearance of Hoftan.

When the Challenger exploded, the two hid to the side of the Polar, but when the explosion occurred, Nelson heard Hoftan's terrible screams on the radio.

Hoftan still didn't dodge! A piece of debris hit Hoftan, and his spacesuit instantly broke a hole, because the interior was pressurized, as a result, the air flow erupted from the position of the hole, so Hoftan could only wave his hands weakly, as if he was a non-swimmer who had fallen into the sea, and he shouted loudly on the radio: "Help me, Nelson!" ”

However, Nelson couldn't move, if he left the Polar, it would be absolutely impossible for anyone to find out, and even, Nelson was thinking, he hung like this, until a few days, months, or even years later, he could still be found, or follow the Polar, fall into the atmosphere together, and complete the process of cremation?

Hoftan was gone, falling into endless darkness, and at the same time, as the oxygen was exhausted, within a minute, the spacesuit also became a vacuum, and the water and blood in Hoftan's whole body would evaporate and become something similar to a mummy. And Nelson, too, only spent the last hours of his life in great fear.

He knew that in fact, no one would come to save him, and a launch of a space flight was not so easy. He just lived a few hours longer than the others.

Now, he has less than half of his oxygen.

The Polar is still flying, at this time, it has flown to the other side of the earth, the sun is shining here, in space, there seems to be something, rapidly approaching? (To be continued.) )
