In addition to serving as a relay station for spacecraft, another important responsibility of "Buzhou Mountain" is to serve as a node for cleaning up space debris.
If the "Buzhoushan" space port had not been on the right track, otherwise the space debris in nearby orbits would have been cleaned up using special technologies and recycled and reused.
However, with only 8 astronauts currently stationed in the huge space port, the undeveloped "Buzhou Mountain" is still not able to handle this kind of danger with ease.
Although the ground command gave permission to abandon "Buzhou Mountain", no astronaut took this final order to heart. Each of them knew very well what the "Buzhou Mountain" air and space port meant to the entire country and nation.
The losses of materials, manpower and funds are also secondary. The most important thing is that it is a heavy blow to China's aerospace industry, which will not be able to recover for at least ten years.
"Danger, danger, Chinese, abandon the space station immediately and push the space station into the atmosphere, quickly! We are too late to rescue!"
From a low orbit about 330 kilometers above the earth, an emergency call from the International Space Station rang in the attitude control room. The other party had obviously noticed an abnormality, and the Chinese "space station" was in danger.
No matter how much they dislike the Chinese and refuse to join the International Space Station program, they do not want to see Chinese astronauts sacrifice. After all, they are living human lives and the most precious aerospace talents.
At this time, no one will rejoice in the misfortune.
Even the Japanese, who just lost a spy satellite for this reason, are praying to Amaterasu that nothing happens to the Chinese "space station" and it is best to remain intact.
Once such a huge "space station" gets out of control, it means that the already troublesome threat of space debris will become even worse, becoming a new nightmare for all artificial satellites, spacecrafts and space stations still in use in space, and may lead to more
The terrible low-Earth orbit blockade will cause human aerospace technology to stagnate for several years.
"Contact has begun! Everyone, protect yourselves."
Seeing that the first light point representing the fragments inevitably came into contact with the Sky Harbor, Wang Xuejun's voice suddenly became louder.
Compared with these space debris, armor-piercing projectiles are simply weak.
At this moment, the skyport began to shake violently, and a crackling sound could even be heard coming from the bulkhead. A warning red light flashed in the attitude control cabin, and the alarm continued to sound.
"Computer, start reporting damage!"
Wang Xuejun shouted while trying to control the air and sky port to avoid it.
"The external isolation layer of South No. 1 and No. 7 cabins has been damaged by 15%!"
Due to the shortage of manpower, the space port control system is highly intelligent and can immediately recognize the astronauts' voice commands.
In the pictures that popped up on several screens, a large piece of the thick protective layer on the surface of the two space capsules was cut off like a double bed.
"The main solar panel on the left side of South 2 has lost 19%, and the East 4 cabin has been penetrated. It has started to automatically repair it and is expected to complete the sealing in 20 seconds."
The damage was not just one, there were more than ten skin injuries in Sky Harbor alone, and one was a penetrating injury.
The fishbone-shaped "Buzhou Mountain" swayed gently, and a large cluster of solar panels that looked like mimosa slowly left the skyport and floated toward the earth.
Perhaps it will not become one of the dangerous floating objects in space and will soon turn into dust in the ionosphere. This is already the best outcome.
Wang Xuejun, who was trying hard to control and avoid losses, had his back completely soaked with sweat. He had just tried his best to carefully control the skyport to choose the most favorable balance between disintegration and being hit by debris.
Fortunately, it was an unimportant empty cabin that was penetrated. If the control cabin was directly hit, the lives of Wang Xuejun and the other three people would still be in danger, and the "Buzhou Mountain" plan might have to be aborted midway.
After 35 seconds, the shaking, trembling and abnormal noise disappeared.
"I finally got through it, it's going to kill me!"
Wang Xuejun felt that his hands were getting weak, and he was even more exhausted than fighting with the enemy for an hour.
"The first wave of impact is over, and the next waves are expected to be after 5 hours, 17 hours, 23 hours, and 27 hours later, lasting at least 1 minute. Well, there will be at least 4 more waves before it is upgraded to an orbit of 1,000 kilometers.
Our troubles are not over yet."
Si Qiang, who was helping to calculate the avoidance route, wanted to reach out and wipe away the cold sweat, but he encountered a transparent barrier and realized that he was still wearing a space suit.
The situation is still not optimistic, but the current loss situation is the best result, and there are no astronaut casualties.
"5 hours? Fortunately, let Mao Jiadong install the SEG immediately. As long as the repulsion shield is activated, we will be safe."
Meng Yinan was panting heavily. He had performed beyond his level just now under his high concentration.
Si Qiang shrugged and said, "That's for the best, otherwise I'm worried about whether Skyport can survive."
"Then give it a try, I won't give up easily."
Wang Xuejun waved his hands and showed no timidity in the face of the challenge.
"There's something not quite right about the SEG mounting slot."
Si Qiang, who was looking at the screens in front of him, saw an unusual signal. He quickly called another astronaut outside the skyport: "Mao Jiadong, go to the SEG installation slot immediately and check."
"Got it! Act now!"
Mao Jiadong, who was holding the SEG sealed box, immediately got out of the external maintenance cabin and continued his original work.
Half an hour later, he opened the sealed cabin where the installation slot was located, looked around, and reported: "Everything is normal, no physical damage was found. Can it be installed?"
"Wait, something is not right, Mao Jiadong, take a look to see if there are any contaminants in the XRAT module. Well, I will send out a signal. Take a look to see if there is a yellow signal light that flashes three times quickly."
Si Qiang's eyebrows became tighter and tighter. The signals fed back by several functional modules in the installation slot were somewhat abnormal.
"Is there anything wrong?"
Wang Xuejun cast his eyes over.
"Six modules failed due to short circuit. I asked Mao Jiadong to check one of them first."
Si Qiang clicked a few times on the screen to display the module elevation analysis diagram of the SEG installation slot.
This is directly derived from the mounting slot structure of the X-8 "Monster" deforming wing fighter. After adjustments by experts, it can be applied to large air and space ports.
"I didn't see it. Let me check first."
Mao Jiadong took out a strong flashlight from his waist and carefully inspected the inside of the installation slot. Suddenly, a few thread-like reflections fell into his sight, which seemed a bit unusual.
He immediately reported the abnormal situation to the control cabin, "Report! Something seems not right. I will share the video with you, using high-power close-up mode."
Through the high-power optical lens on the space suit, I immediately locked onto those unusual reflections.
"Is the wire loose somewhere?"
Wang Xuejun, Meng Yinan and Si Qiang looked at the ox hair filaments that appeared on the screen with metallic luster in confusion. The computer system automatically recognized the size, which was about 1.78 centimeters in length.
"It's not the circuit wires on the mounting slot, it's the Seaford pins! That's an American thing."
The astronauts heard the voice of the ground command, and the ground personnel obviously recognized what it was.
The West Ford Needle Project, which consists of a copper dipole antenna, is an auxiliary project for Americans to spread metal needles in low-Earth orbit to form a cloud-like ring to reflect radio signals, and then conduct long-distance communications through a satellite antenna installed in the town of Seaford
.
Fortunately, it was only launched once and was aborted. Otherwise, the entire outer space orbit would be covered with 430 million copper dipole antennas with a total length of 1.78 centimeters and a diameter of 25.4 microns that were pushed out of orbit by the pressure of solar radiation.
"The sealed cabin cover was penetrated and extremely tiny holes were found."
Mao Jiadong revealed the traces of these fine needles. The densely packed small holes on the outer surface of the hatch cover made people's scalp numb. In the impact just now, the SEG mounting slot unfortunately encountered a ball of Seaford needles.
Even though these small needles are inconspicuous, the penetrating power brought about by the speed in space will be very terrifying. A very small number of fine needles successfully penetrated into the installation slot and destroyed some modules due to the unremitting efforts of the predecessors.
components.
"To prepare to replace the damaged modules, we must activate the repulsion shield as soon as possible, otherwise we will have to give up 'Buzhou Mountain'."
The ground command did not hesitate and immediately issued the latest instructions. They did not believe that the current situation of the air and sky port could survive the next four rounds of impacts.
"The spare parts for the SEG installation slot are stored in East No. 4 cabin! Uh"
The three people were speechless. They remembered that just now, the system reported that the cabin that had been penetrated was the East No. 4 cabin.
"I'll go to the East No. 4 cabin to check!"
Fan Liming, who was responsible for repairing pipe damage, immediately took action. While quickly passing through the cabin and nodes, he said: "Si Qiang, help me block the nodes, prepare to evacuate the air in the East No. 4 cabin, and tell me the location of the spare parts. Mu Hong."
Tian, enter sleep mode for one hour and set off in one and a half hours."
"yes!"
Another astronaut also quickly prepared, racing against death.
"Only one intact spare part was found, the other spare parts were damaged!"
A moment later, Fan Liming, who was only holding the module components like bricks, looked at the messy East No. 4 cabin with an ugly expression, as if the place had just been hit by an armor-breaking bomb, and many spare parts were damaged to varying degrees.
It seemed that a piece of metal fragment the size of a cattail leaf had penetrated the cabin shell and disintegrated into countless fragments in the cabin. Only two pieces with strong kinetic energy penetrated out from the other side of the cabin shell unabated.
The breach has been temporarily sealed with high-strength gel.
It was very unfortunate that the spare parts shelf in the SEG installation slot was directly hit by a metal fragment that penetrated into the cabin. It was very lucky to be able to find an intact spare part.
The eight astronauts and the ground command in the space port were actively discussing response plans one second, but fell into a collective silence the next second.
It was really a leaky house and it rained all night, it was really fate that just when it gave people a glimmer of hope, it kicked them into the gutter. The feeling of rising and falling almost makes people spurt blood in depression.
"Organize an emergency launch immediately! Rush to transport spare parts!"
Someone from the space agency broke the silence, but unexpectedly received no response——
