On the ground, Xia Yu, who had just received a notice to suspend takeoff, had to stay in the cab and wait for a new notice, although this sudden suspension of take-off was not unencountered, but looking at the ground staff who were suddenly busy, somehow, Xia Yu always felt as if they were preparing to do something terrible, turned his head to look at Wang Pengyu who was doing calculations, Xia Yu said: "Pengyu, what do you think the ground crew plans to do with our plane?" ”

Wang Pengyu was stunned when he heard this, raised his head and looked at the hangar outside from the window of the wheelhouse. Sweeping his eyes into the hangar, Wang Pengyu was a little stupid, he didn't turn his head back, and said in a daze: "Isn't that the auxiliary rocket booster of the Shenlong?" What are they pushing out for? ”

Wu Degao and the three of them were stunned when they heard this, and immediately stepped forward to look in the direction of the hangar. In the hangar, four booster rockets of the Shenlong have been loaded onto the scaffolding car, and another group of staff is adding fuel to the booster rockets, and one of the booster rockets that has been filled with fuel is being transported to the Shenlong side, which makes Xia Yu a little confused. Today is just an ordinary transition flight, not to mention rocket thrusters, even the scramjet engine does not need to be started, why does it look like it is going to space now?

And even if it is going to space, Shenlong can already break out of the atmosphere just by virtue of the power configuration combination carried by the airframe itself, and the use of booster rockets to fly is only one of the backup plans of Shenlong, and it is generally impossible to use booster rockets, that is, an unusual situation has occurred? Xia Yu secretly speculated.

Soon, Xia Yu's guess was confirmed, and it was a contact from Yuan Limin. The content of the call was Tiangong-1, which had just been attacked by space debris, and Yuan Limin asked Shenlong to urgently dispatch to save people in space.

This can surprise Xia Yu, Shenlong itself as an aerospace aircraft, generally flying at an altitude of about 100 kilometers from the ground, and the location of the space station is more than 400 kilometers from the ground, that altitude is the field of the space shuttle, for the relatively small aerospace aircraft, if you want to reach that position, you can't do it just by relying on the power configuration it carries. Therefore, don't look at the short distance of more than 300 kilometers, if you want to break through to that height, you can't really fly without the four booster rockets Shenlong, and even so, Xia Yu estimated that it was very reluctant. But the mission is the mission, and it is also to save his own astronauts, Xia Yu has no other ideas, and he knows it in his heart at the moment, and gives an order to prepare for an urgent space flight mission.

Fifteen minutes ago, Tiangong-1, which was attacked by space debris, has recovered to normal at this moment, except for the broken interface that originally connected to the Shenzhou spacecraft. The lost air pressure has been restored, and the operation of the various systems has not found any abnormal conditions, it seems that ten minutes ago, none of the qiē that happened here is really the same, except for the core cabin that was supposed to be three people, only two people are there at the moment.

The surviving Liu Hongliang and Yang Yi were busy nervously, in addition to checking the condition of the space station, they also had to report to the ground what happened in space. The most important thing is that there is no such thing as a garbage recycling station in space, and the new debris generated in the collision, except for some of which will burn up in the falling atmosphere, will become new space debris, continue to orbit, and become a new threat.

These two people don't even have time to be sad, they have to do their best to move Tiangong-1 again, with those space debris flying at a speed of more than 20,000 kilometers per hour, it only takes about 90 minutes, and their flight trajectory will coincide with the space station again, if you don't want to be hit a second time, it's best to slap your ass and flash people immediately.

However, when they tried to ignite the main thruster but couldn't do anything, the two pale astronauts hurriedly contacted the ground to report the situation and request technical support.

"How about we ask for help from the International Space Station?" In the flight control center, a staff member in the decision-making area proposed to build a plan.

"I have been in contact with the International Space Station just now, the collision of the debris with Tiangong-1 has had a chain reaction, they have also been hit by space debris, one of the spacecraft has been destroyed, and the remaining two have returned to Earth with their own people, and now the International Space Station is empty." The other replied with a shake of his head.

The situation has become tricky, the Shenzhou spacecraft has broken away from the space station, I don't know where to float, the two astronauts have no place to go, the only thing they can do is to find a way to repair the main thruster to leave the orbit of the space debris, otherwise if it is hit again, the consequences will be unimaginable.

"Command center, this is Tiangong No. 1." Liu Hongliang's voice sounded in the flight control center, before he and Yang Yi had been trying to repair the main thrust engine, but they could not find the reason, until Yang Yi decided to walk outside the cabin, and when he visually determined the situation, he found that the main thruster had been completely damaged in the previous impact, and there was no possibility of repairing it in a short period of time, they could no longer think about it.

Liu Hongliang's report made everyone in the flight control center feel dead, and now no one can help the two people who are still floating in the universe. In the case that there is no way to move Tiangong-1, even if the fragments of the next rendezvous will not hit Tiangong-1, there will be another time, and there will be the next time, and there will be the next time......

Luck will not always favor Tiangong-1, not to mention that praying that the next fragment will not hit it is a delusion in itself, if there is really no other way, Tiangong-1 will definitely not be able to avoid the fate of being destroyed. Because even if they prepare to launch a rocket into space as quickly as possible to help them, that set of operating procedures that are so complicated that they can't be simplified at all will be done at least half a month later, and it is impossible for Liu Hongliang and Yang Yi to persist until that time.

"Is there really nothing we can do to help them?" A staff member couldn't help but shout with tears in his eyes: "Is it true that we can only watch the two of them die like this in the sky?" ”

In the flight control hall, everyone was silent, because no one knew the answers to these two questions, so at this moment, in addition to silence, they could only continue to remain silent.
