Yuan Limin was greatly stimulated today, and the ups and downs of the whole person's spirit fluctuated so much that he felt that his heart was a little unbearable. This twist and turn is carried out, not to mention that I have a little problem with my heart, even if I am a healthy person, I am afraid that I will not be able to bear it.

Fortunately, the final result is still good, Shenlong has taken Tiangong-1 out of the orbit of those space junk, although Shenlong's wings were damaged due to the impact of space debris, and it could not break into the atmosphere and return to Earth, but there was enough food in Tiangong-1 for Xia Yu and the seven people to hold on for at least two months. Therefore, the next only need to let them continue to hold on to the sky for half a month, and then arrange for the rocket to take them back, Yuan Limin wiped the sweat stains on his forehead, and he could finally sit down with peace of mind on his chest.

It's a pity that he didn't sit down for long, and he hadn't even covered his buttocks yet, and Wang Pengyu's report made him jump in shock. There was a problem with the rocket thrusters of the Shenlong, and no one in the flight control center needed to think too much to understand what it meant. If you can't stop the Shenlong from continuing to accelerate, with the Shenlong's full load of fuel, it will be enough to push Tiangong-1 to the depths of the universe where it can no longer be found.

"Have you tried to turn off the Dragon's main power?" Yuan Limin picked up the intercom and shouted, "What about the system restart? What about circuit breakers? ”

"I've tried it all, and nothing happens." Wang Pengyu has always been responsible for the liaison with the flight control center, and at the same time has to take into account the observation of flight parameters, and is responsible for a variety of tasks at the same time, but there are many strict problems, Wang Pengyu's voice has become a little anxious: "The thrust of the Shenlong is increasing, and now the orbit change speed is 3.5 meters per second, and the orbit speed is 8.7 kilometers per second, our speed is getting faster and faster, and there is no way to control it!" ”

"Understood." Xia Yu replied that he heard it, and he and Wu Degao were doing calculations, and they had to figure out a way before Shenlong accelerated to a speed of 11 kilometers per second, otherwise once they reached the second cosmic velocity, the earth's gravity would no longer be able to bind Tiangong-1, and they would leave the earth's orbit like a shot put thrown out.

"At our current level, we still have an hour." Wu Degao was still calculating, and Xia Yu had already come up with the answer: "In an hour, our speed will increase to 11 kilometers per hour, and then there will be no way to stay in the earth's orbit, what do you think?" ”

"We can adjust our posture and let the Shenlong slow down Tiangong-1." Wu Degao said: "In this way, we can avoid entering the second cosmic velocity, at least we can stay in the Earth's orbit." ”

"Well, I'll see." Xia Yu immediately calculated, in order to save time, he even entered the consciousness space and directly used the simulation method, in just thirty seconds, Xia Yu shook his head and said: "It doesn't work, we can't control the thrust of the Shenlong, and we can't let the gas thruster work all the time, according to this calculation, in the end, we will even lose speed and fall directly to the surface of the earth, and we don't even have time to adjust the attitude again, Tiangong-1 is too heavy, if it's just the Shenlong, it's still possible." ”

"Then what if we give up Tiangong No. 1 and take Liu Hongliang and them to the Shenlong?" Wang Pengyu asked, but as soon as he finished speaking, he shook his head and denied this possibility, and said: "If you want to stay in space for a month, then the oxygen supply and power supply of the Shenlong will not be enough, damn it, what should I do?" ”

Wu Degao seemed to have nothing to do, shaking his head and not knowing how to answer, Xia Yu's brain was running rapidly, simulating various possibilities with the starry sky in the consciousness space, but at this time, the rocket thruster of the Shenlong suddenly erupted a huge flame, and the abnormal thrust increase immediately made the alarm sound in the cockpit, Xia Yu and the three of them were startled, and hurriedly looked at the dashboard.

This look, but the three of them were shocked, the rocket thrust of the Shenlong is growing upward, according to this speed, it will not take long to become a state of full acceleration, this is terrible, the sudden acceleration just now has made the docking place creak, and if it continues to accelerate like this, it is impossible to determine how long the docking can last, gritting his teeth, Xia Yu can only use the simulation that he has only done half of the time in the consciousness space just now to deal with it.

"Pengyu, contact Tiangong No. 1 and ask them to carry us a month's worth of food and water." Xia Yu gave an order: "Old Wu, let's go and remove the backup power supply and oxygen exchange equipment of Tiangong No. 1." ”

Wang Pengyu and Wu Degao were stunned when they heard this, but immediately started working. Neither of them is stupid, Xia Yu immediately understood as soon as he heard his words, Xia Yu must be planning to let the Shenlong break away from Tiangong-1 and run in the earth's orbit by himself, because if there is only Shenlong itself, it can easily adjust the flight attitude, and there is no need to worry about not being able to move quickly because of too much mass, and then being forced to leave the earth's orbit because of too fast speed. In this way, as long as some materials to maintain basic survival are transported from Tiangong-1, there is still a possibility of holding on for a month.

After Wang Pengyu contacted Tiangong No. 1, Liu Hongliang and Yang Yi on Tiangong No. 1, and Du Junbao and Wu Min, who were then transferred from the Shenlong to Tiangong No. 1, hurriedly passed the daily necessities to Shenlong No. 1. It is inconvenient to move in space, but if you just fix yourself in place, and then simply push the boxes of living materials forward, it is much simpler, and the speed of moving living materials is generally not slow.

However, it took Wu Degao nearly ten minutes to dismantle the oxygen exchange equipment and backup power supply of the No. 2 real yàn cabin, at this time, the Shenlong had increased the orbit change speed of Tiangong-1 to nearly 15 meters per second, and the docking site was pulled by the acceleration of the Shenlong, and the crunching sound was more obvious, and even a slight deformation could be seen with the naked eye.

"Hurry, hurry, hurry!" Xia Yu floated at the docking place between the Shenlong and Tiangong No. 1, he had been nervously paying attention to the situation of the interface, although he didn't know how long he could hold out here, but Xia Yu felt that there was almost no time.

Wu Degao held the backup power supply, kicked his legs on the bulkhead of the space capsule, and the whole person accelerated towards the Shenlong. Xia Yu let go of his figure, and after making sure that Wu Degao had entered the Shenlong, he reached out and took the box of food pushed over by Du Junbao in his arms, and then hurriedly drilled into the Shenlong No. 1.

"Crunch-" A sharp and piercing metal sound came again, making people a little frightened, Du Junbao was about to follow Xia Yu into Shenlong No. 1, when the docking place suddenly made a piercing squeak again, almost at the same time, the alarm in Tiangong No. 1 and Shenlong suddenly sounded, Xia Yu looked at the place where the sound was made, and was suddenly startled, at the docking place, a crack that was so small that it was almost invisible was hissing and leaking air into space.

"Go back! Stay back! Xia Yu shouted at Du Junbao: "Hurry up and close the isolation hatch, it's going to crack here!" ”

Du Junbao was shocked when he heard this, and was about to hurry up and follow Xia Yu into the Shenlong, when suddenly the crack became bigger again, and the sudden increase in airflow even stirred Du Junbao's body, making him instinctively grab the handrail next to him to fix himself, and then he listened to Xia Yu again: "You stay in Tiangong No. 1 and wait for rescue, we will find a way by ourselves, hurry back to the space capsule and close the isolation door, I am going to close the door of the Shenlong." ”

"Wait ......" Du Junbao didn't have time to finish speaking, he saw Xia Yu reflexively close the hatch of the Shenlong, and before the last crack in the door was completely closed, Du Junbao also saw Xia Yu give him a thumbs up, and a very calm smile appeared on his lips.
