In low-earth orbit in space, about 356 kilometers above the ground, a huge man-made object is being constructed. The man-made object is 112 meters in diameter and 453 meters long, and its entire shape resembles a giant mushroom that has been stretched.

"George, please answer when you hear it!"

Around this "space mushroom", there are a number of spacecraft floating, these spacecraft look similar to small space stations on the surface, with pipes protruding from below them, and connecting with the "space mushroom" not far away, from a distance, like slender limbs sticking out of the "space mushroom".

"This is George, this is George!" A clear reply came from the communicator, and Doolittle and his assistant operated the control platform, staring at the fluorescent screen in front of them: "How are you over there?" Please report back. ”

"The situation is good, please rest assured ......." George's voice came from the communicator.

"Please do the final internal inspection, report the results after the test, and wait for the closing command."

"Understood, do the final internal inspection, wait for the closing command." George replied.

At the end of the call, Doolittle tapped on the keyboard for a while, then pressed on the chair, and the whole person floated in weightlessness, and his feet kicked the bulkhead, and he easily "fled" to the rear of the cabin under the reaction force.

Today, the last part of the Hades spacecraft is closing in at a critical juncture, and around the "space mushrooms," the newly named Hades spacecraft, the floating and connected spacecraft are in fact the command centers and facility attachments that will be responsible for the construction. Their main role is similar to the scaffolding, cranes and other facilities used in ordinary construction, of course, the construction of such a spaceship in space is different from the ground, these facilities and accessories not only have to undertake the construction work, but also the necessary place for the construction personnel to rest, in addition, but also to use their own power for the entire spacecraft to raise the orbital height before the construction is completed.

In near-earth orbit in space. Due to the attraction of the earth and the atmospheric drag around the orbit, space vehicles, including satellites, space stations, etc., will have a continuous downward orbit. Therefore, in order to prevent the occurrence of crashes caused by the orbital height exceeding the bottom, the orbital altitude must be raised frequently. to ensure that it does not run off the track.

From the very beginning of the entire spacecraft construction, the United States has built these spacecraft to solve this problem, and at the same time, it can also use them for the construction and construction of spacecraft as auxiliary facilities. From the current point of view, the effect of this plan is very good, after more than three years, the main structure of the entire Hades spacecraft is basically completed, only after the last part is closed today, then it marks the end of the construction of the Hades spacecraft.

Doolittle made his way to the back of the capsule, and through the round window, he could clearly see the space outside. He was more than 500 meters away. An irregular structure of about 60 cubic meters is firmly grasped by four huge manipulators, and below the construction is the tail of the Hades spacecraft, where 99% of the overall surface has been completed There is a black hole, and this hole is embedded in the position of the structure, as long as the construction is placed in the corresponding part according to the program, and then the astronauts who have entered the Hades spacecraft and the operator outside cooperate to close the construction and the main body, then it marks the completion of the structure part.

Doolittle is the engineering commander and one of the outside operators who perform the closure. He knows it well. Work like this must not be done in the slightest mistake. Failure to close would not only damage the ship's structure, but also delay the entire plan.

"Hull, how are you doing over there?" Dulittle Thong Guò communicator asked the control room on the other side, this time it is crucial to operate the external operator, the four huge manipulators will be synchronized by the external operators of the two control rooms. Another outside operator who is also responsible for this important job is his colleague and good friend Hull.

"What else? After waiting for a long time, I said can you hurry up? A lazy voice came from the communicator, and if you just listened to the voice, you might think that the other party was a bad person, but he could be a friend of Hull. Doolittle knew that Hull's skills were by no means below him, and if it weren't for his withdrawn personality and this stinky temper, he might have been promoted a long time ago.

"Seriously, Hull, I don't want to see failure." Frowning slightly, Doolittle warned sternly. You must know that every conversation between them will be recorded, in case the closing is not successful, Hull's tone and attitude alone is enough for him to drink a pot, as a supervisor, Doolittle knows the style of those big people above, and when he succeeds, he is more energetic than anyone else, once something goes wrong, the first thing that comes to mind is how to shirk responsibility, Doolittle doesn't want to let people catch him because of Hull's casual attitude.

“OK！” Hull's voice was a little more serious: "I'm ready, waiting for the command ......." ”

This serious sentence came out of Hull's mouth, and Doolittle felt awkward in his ears, and he imagined that the demeanor that appeared in Hull when he said this must have been a look of disdain. But no matter what, at least there will be no problem with the record, thinking of this, Doolittle replied with a word of understanding, let Hull continue to wait for instructions, and then pushed the bulkhead hard, and the whole person rushed back to the control platform like an arrow.

Returning to the control platform and sitting down, the assistant next to him told him that George from the inside of the Hades spacecraft had sent a message just now, and that the preparations inside the spacecraft had all been prepared, and the final inspection had just been completed, waiting for the final closing command.

"Attention teams, attention to teams!" Doolittle turned on all the communications and began to give orders as commander: "Close will officially begin in three minutes, and now counts down." ”

356 kilometers above the ground in space low earth orbit, looking down from space, the huge earth is so clearly visible, blue oceans, green forests, yellow plains, white mountains, ribbon rivers...... And then there are the cities that are faintly shining. But people on Earth don't know that above their heads, in space, a huge spaceship is being built at this time.

The three-minute countdown quickly passed, and as Doolittle's order to close officially began, the four huge manipulators slowly moved, and the entire structure began to change positions from stationary.

"Hull, keep in sync."

"Understood, keep ...... at the same time."

As long-time friends, Doolittle and Hull have a chemistry that no one can match, which is why Doolittle has appointed Hull as a second external operator to assist him. Under the tacit manipulation of the two of them, the huge manipulator was like a person's dexterous hands, fiddling with the structure suspended in space, slowly but surely moving towards the final closing part of the Hades spacecraft.

"100 meters...... 90 m ...... 80 m ...... 70 m ...... 60 meters ....... ”

When the distance is finally close to 30 meters, the robot begins to slow down and fine-tune to ensure the correct position.

"George! Please pay attention to the in-house guidance! ”

"Roger, internal boot starts booting ......."

Inside the Hades spacecraft, George and several of the astronauts were ready to turn on the internal bootstrapping process to ensure accuracy and safety as the structure approached.

"30 meters...... 29 m ...... 28 m ...... 27 meters ....... ”

The speed of the manipulator began to slow down again, and the most critical moment was coming, and the huge structure was like a jigsaw puzzle played by children, inserted precisely towards the reserved place. But it is different from toys, for toys, the insertion failure can be done again, but if the structural closure fails, then the entire structure will cause damage in the collision, and even affect the main part that has been formed, thus delaying the whole plan.

"8 meters...... 7 meters...... 6 m ...... 5 meters ....... ”

Getting closer and closer, the entire structure is now almost closed to the main body from a distance, but both Doolittle and Hull, who are manipulating, know that the real success or failure is at hand.

"Doolittle, 0.11 degrees to the left!"

Just when he was finally close to 1 meter, Hull suddenly shouted in the communicator, Doolittle didn't think much about it, out of trust in his friend, his hands reacted instantly, and at the last moment when the structure was closed, he completed the manipulation of 0.11 degrees to the left.

"Sir......." The assistant didn't expect this to happen at the last moment, he was shocked when he had been watching the guide monitoring, and just about to stop Doolittle had completed the operation, and at this moment, the structure had reached the position, and the manipulator began to loosen accordingly, and at the moment of release, the structure was actually offset to the right by a very small angle due to the reaction of the manipulator when it was released. It is precisely because the subtle manipulation of Doolittle and Hull's 0.11 degrees to the left just now was corrected at the same time, and under the stunned eyes of the assistant, the entire structure entered the position in the most perfect posture, and with a light shock, the most critical step was completed.
