"Disengagement docking countdown, 3, 2, 1, disengage."

As Wang Pengyu's words fell, the docking place between the hatch of the Shenlong and Tiangong No. 1 clicked, and the connection of the circular passage that was originally tightly locked was opened, and the only remaining air between the two hatches instantly stirred and rushed into space, in the eyes of Du Junbao and others, the Shenlong rushed forward the moment it was disconnected, and flew away silently.

"The disengagement and docking were successful, the orbit speed was 9.6 kilometers per second, and the orbit change speed was 37 meters per second, and we were ready for attitude control." In the cockpit of the Shenlong, Wang Pengyu read the current flight parameters: "The thrust of the rocket is one-fourth, and it continues to increase, one-third of the remaining fuel, it is expected that there will be forty-five minutes before the fuel consumption is completed, and the maximum speed is expected to be 15.6 kilometers per second." Xia Yu, our maximum orbital speed is too fast. ”

When Xia Yu and Wu Degao heard this, they immediately began to recalculate the orbit information, and on the ground, Yuan Limin and others, who had already received the news, looked at the orbit of the Shenlong displayed on the big screen, and began to calculate it one after another.

At present, the orbit of the Shenlong has become elliptical, the perigee is only 202 kilometers at an altitude, and the apogee has reached 870 kilometers, which is an altitude that is almost out of the dispersion layer, and the uncontrollable increasing speed will only throw them out of the earth in the end, even if they control the flight attitude of the Shenlong, there is no way to stop it.

But no matter how he calculated, Yuan Limin couldn't find a way to keep the Shenlong in orbit under the condition that the speed kept increasing, and in the end, Yuan Limin only felt that his eyes were dark, and his chest was stuffy for a while, and he actually sat down on the command platform like this, which immediately caused a commotion.

"Doctor!!" Cao Yanhua helped Yuan Limin and shouted, and not far away, several people wearing white coats and hanging signs of medical staff hurriedly ran towards the command area. Working in the space city, few of the older scientific researchers are in good health, and many years of research and work have always kept them in a sub-healthy state, and they are in a state of high tension every time they have a flight mission, so a corner of the flight control hall has opened up an area for medical staff to use, ready to rescue these precious Chinese astronauts.

Yuan Limin is not the first astronaut who fell on the workbench, and he will not be the last, and the medical staff have long been used to it.

"No, it doesn't matter." Yuan Limin clutched his chest, struggling to stand up. He didn't lose consciousness, just now he suddenly felt a tightness in his chest, he couldn't breathe in the air and was deprived of oxygen, so he had no strength in his body, so he sat down, and this sitting suddenly reminded him of a method that even he thought was extremely ridiculous, but it seemed to be a feasible method.

"No, your body is important, hurry up and let the doctor check it." Cao Yanhua didn't want Yuan Limin to work with his sick body, if he really had a heart attack, he couldn't delay the time for diagnosis and treatment.

"I'm fine." Yuan Limin took a few deep breaths, and while cooperating with the medical staff to diagnose him with a stethoscope, Yuan Limin said: "I may have a way to save the Shenlong, let me make a calculation first." ”

"No, I don't allow it." Cao Yanhua darkened his face and said in a deep voice: "You must be examined first, if you also fall here, our losses will be even greater." ”

"What's the loss?!" Yuan Limin was anxious, and stood up as soon as he could, so frightened that Cao Yanhua hurriedly held him up. I saw Yuan Limin gesturing his hands and said excitedly: "It's too early to give up Xia Yu now, even if they can't stay in the earth's orbit, we have to find a way to save them, they were sent by me, and I have the responsibility to take them back!" ”

"Okay, okay, I know, I know." Cao Yanhua didn't dare to continue to stimulate Yuan Limin, and pressed Yuan Limin to the seat comfortably, and then said: "You calm down first, I didn't say that I want to give up on them, but now we have no way to keep the Shenlong in the earth's orbit, unless we can turn off the rocket engine of the Shenlong, do you have a way?" ”

After taking a few deep breaths in a row, Yuan Limin said: "I can't turn off the rocket engine of the Shenlong, but I just thought of another possibility, if it is feasible, then this is the only way for us to save Xia Yu and them." ”

In the cockpit of the Shenlong, Wang Pengyu continued to monitor the flight parameters after reporting the reading, but Xia Yu quickly came to the same conclusion as Yuan Limin: If there is no way to turn off the rocket engine, there is no possibility that the Shenlong will remain in the earth's orbit.

What to do? Xia Yu pondered, no matter what danger he encountered, he could not give up hope of survival. This is not only what the instructor has always emphasized to him when he was in flight school, but also the style he has always done. But this time he is in space, and he is constantly accelerating out of the earth's gravity, if he is really sent out of the earth's orbit and into space, the Shenlong will eventually be unable to control it because of the lack of fuel, once even the last backup power is used up, Xia Yu really can't think of any way to continue to survive.

"No, we're too fast, and the perigee is too close to Earth." Wu Degao also finished the calculation, and said dejectedly: "Even if you forcibly change the flight attitude, it is useless, in the end, you will either fly out of the earth's orbit, or rush into the atmosphere and burn up, there is no way." ”

"It's too early to tell." Xia Yu didn't give up yet, and said: "According to the calculation of the orbit, there are at least 3 hours before we are thrown out, let us try to think about it during this time, there will always be a way." ”

Wu Degao didn't answer, he really didn't know what else to think about, the Shenlong had been accelerating, even if the rocket engine stopped working because there was no fuel, but the speed of 15.6 kilometers per second was close to the third cosmic speed, which was the speed that could break away from the solar system, and the earth's gravity could not drag the Shenlong like a red-eyed and crazy man.

Wang Pengyu looked at the increasing flight speed and various other flight parameters, but his mind was a little blank, although he had repeatedly encountered various dangers before, he never thought that he would die. He believed in the Shenlong, Xia Yu, Wu Degao and the other team members, and he believed in his ability to deal with the problem. But now, he really didn't know what to do.

"Shenlong, this is the command center, please answer when you receive it."

Just when Wang Pengyu and Wu Degao were frustrated, and Xia Yu was still trying to think of a solution to the problem, a contact from the flight control center suddenly came from the radio communicator.

"This is the Shenlong, please tell me from the command center." This is the first time that Xia Yu has connected to the flight control center during this space flight.

"Natsu-chan?" Yuan Limin's surprised voice came from the communicator: "It's Xiao Xia, right?" I thought of one that might allow you to hold on to a rescue. ”

End of chapter.

PS: Ahem, this seems like the first time I've spoken in the text? Well, without further ado, speed gets to the point. According to the current situation, I don't think it's too difficult to guess Yuan Limin's method, so if a brother can write this method in the book review area, I will refine it. It's really dripping, it's not deceiving, it seems that there are more than fifty essences that are useless, first come, first served.
