The speed of the launch vehicle is extremely fast, and the carrier module is sent into the weak gravitational zone of the dispersion layer in just about ten minutes, but the next trip is completely handed over to the four magnetic plasma engines of the carrier module, and it takes nearly two hours to approach the "Buzhou Mountain" air and space port at an altitude of about 00 kilometers above the ground.

The carrier module is still 42 kilometers away from the air and space port, which is almost an extremely long distance within the ionosphere, equivalent to two-thirds of the distance between the east and west ends of Eurasia, and twice the distance between the east and west or north and south of China.

But in outer space, this distance is almost nothing.

In low-Earth orbit 22 to 4 kilometers above the Earth's surface, any space junk can cover such a distance in about a fifth of a second.

This distance is completely within the careful calculation of the experts of the China Space Agency, which is a very safe distance for the "Buzhoushan" air and space port, and it is also the distance that the carrier module can approach at the most appropriate time.

"The distance is 0 kilometers, the remote control and automatic driving system are switched to auxiliary control, Lieutenant Colonel Meng Yinan, please start to enter the docking process, 'Buzhou Mountain', please be ready to capture."

The liaison officer in the lobby of the ground command center announced the operation to move on to the next process.

Lin Mo was already at the back of the command center hall at this time, and he was in a rare and nervous mood at the two points of light representing the carrier capsule and the "Buzhou Mountain" air and sky port, and was slowly approaching in the simulated space three-dimensional graphics.

As a former astronaut candidate, Lin Mo knew that docking in outer space was a very troublesome thing, and its difficulty was far more difficult than the in-flight refueling of fighter jets.

Not to mention that the two sides in motion are at least 46 times faster than fighters and tankers (7,900 meters per second and 70 meters per second and 62 kilometers per hour for tankers), and if the docking hatch is not completely seamless, the poor airtightness will lose a lot of precious air.

In outer space, air is even more important than life, not only astronauts need it to maintain life, but also the electrical equipment and other systems in the capsule also need it to cooperate with convection to dissipate heat.

In the event of an accident, I am afraid that China's "Buzhoushan" plan may also be lost, so every docking is a high-risk and high-precision work.

It may not even take more than ten hours to complete the docking. Of course, for the survival material reserve of the carrier module, a delay of more than ten hours will mean that the astronauts in the cabin will be in danger.

"Meng Yinan received!"

"Wang Xuejun received!"

As an astronaut in the same period, the arrangement of the superior also takes into account the tacit understanding between the two astronauts, and this kind of exercise has been carried out many times.

Meng Yinan reached out and grabbed the control panel and joystick. And at least a hundred times of training. Maneuvering the carrying capsule, he began to cautiously approach the "Buzhoushan" air port.

The difference is a millimeter, the loss is a thousand miles, and this idiom will become a true portrayal in outer space.

The boss is on the ground, and he must perform perfectly. Meng Yinan silently encouraged himself in his heart.

'Come on!' Tabby Cat'! ”

Lin Mo stared at the big screen, as if he was engrossed in the little brother on the screen.

I don't know for what reason, the communication staff passed Lin Mo's words in a timely manner.

"Yes! Top dog! ”

Hearing the old voice in his ears, Meng Yinan's face did not change at all, as if he hadn't heard it, but his eyes were more determined as if he had a backbone.

It's as if the boss was instructing himself in air combat skills. With constant guidance and encouragement, he will definitely be able to succeed at the first time.

In front of the docking console of the "Buzhoushan" air and space port, Wang Xueping is constantly reporting the number, which means that the speed of the two sides is slowly becoming the same, and the carrier module is very close to the air and space port. Start entering the co-directional docking corridor.

Wang Xuejun gently operated on the console with both hands, and as an excellent fighter pilot, he also had a pair of extremely sharp and stable hands.

At the berth of the air and space port, a robotic arm about 30 meters long was automatically stretched out, and it was carefully grasping the carrier module.

There was silence in the air port, in the carrier compartment and in the command center. Only the slight sound of breathing could be heard, and at such times, no one dared to be careless.

"The engine has been turned off, and the carrier compartment is ready! Distance 0 meters. Relative velocity, the velocity difference is 0. Sinusoid"

Meng Yinan began to report the final number, the speed of the two sides has converged infinitely, the carrier module has entered the last step of operation, and the rest is Wang Xueping.

"Open the magnetic field and start capturing!"

Wang Xueping, who has also practiced hundreds of times, accurately and steadily controls the robotic arm to open three four-section claws to grasp the carrier compartment, and the special device located in the center of the claw is releasing a magnetic gravitational field, calibrating the angle little by little.

"Captured! Complete the hard connection! ”

Before Wang Xueping's voice fell, the entire air and space port and the carrier cabin were almost imperceptible, and the mechanical arm on the berth had steadily grasped the carrier compartment into the heart of the claw, and could no longer break free.

And that's just a small launch capsule, and if it's a large shuttle, it may require more robotic arms to assist in the capture.

Some corners of the "Buzhou Mountain" air harbor lit up with a faint blue light, flickered for a moment, and then extinguished again.

"The 'Buzhou Mountain' balance system began to compensate and coordinate, and the coordination was completed."

In the attitude control module of the air and space port, the voices of other astronauts were heard, and although the capture was completed, the air space port still received very little kinetic energy.

If we do not carry out precise coordination and compensation, the accumulation will gradually leave the original position and speed, and may even fall into the atmosphere.

This very brief adjustment also included the carrying compartment on the robotic arm by the way.

"Start docking! Release the robotic arm. ”

At this moment, it is completely Wang Xuejun's home field, controlling the robotic arm to align the door of the carrier module with the berth door of the air port.

With a slight movement of the robotic arm, three four-legged claws arranged at 20 degrees released the carrying compartment with extreme lightness.

The initial operation of the space port also relies on a large number of manual operations, which will provide a large amount of practical reference data for China's space authorities to facilitate future automation upgrades.

The docking positions of both sides are lit up, the attitude change of the carrier compartment is completely under the control of the berth hatch, and the invisible magnetic beam is slowly adjusting the distance and entry position of the two sides.

Smack, a soft sound!

"The first step, the lock port is locked, the second step, the correction lock is completed, the third step, insert the data connection, complete the system docking, the fourth step, start the air seal lock, the fifth step, the safety verification, the sixth step, adjust the cabin pressure and air tightness, and allow entry."

It took at least 24 steps for the carrier module to officially complete the docking with the air and space port.

After detaching from the shroud of the launch vehicle, the launch capsule has always been a magnetic isosphere engine, which does not mean that it does not have a conventional rocket propulsion engine, after the start of manned launches, the first few batches of manned launch capsules have solid-state rocket engines and magnetic isosphere engines, if nothing else, once these capsules complete docking with the air and space port, they will never return to the earth, they will be used as the escape pod of the air and space port, has been fixed on these berths.

In the event of an accident, these capsules will serve as an escape capsule for the astronauts of the spaceport.

Although there are only four astronauts in the capsule for each launch, in fact, these capsules for emergency escape are designed to be rated for two people, and can carry two astronauts to safely break through the atmosphere and return to Earth.

"Boss, I made it! Ha ha! ”

Meng Yinan made a V-shaped gesture at the camera in the carrier compartment, took the lead in grabbing the cabin arm and drifted into the docking channel, and smoothly entered the "Buzhou Mountain" air and sky port.

At this time, a warm applause and cheers broke out in the command center hall of the Jiuquan Satellite Launch Center.

Every successful launch is a challenge and an affirmation of the operational quality of the launch center.

The successful completion of the docking at one time is completely worthy of the pride of China's astronauts, which will mean that more astronauts can be successfully stationed in the air and space port.

"Now let's start importing goods!"

The joy was short-lived, and the command center began to get busy again, although the launch capsule rated to carry 2 people only sent 4 astronauts up, it does not mean that those carrying capacity were also wasted, food, water and other important life support materials have always been the top priority in the launch and delivery mission.

Several chunky packages, as if boxing punching bags, were delivered through the butt hatch.

"It's time for me to go!"

With a faint smile, Lin Mo nodded towards Wei Yunyi, and he was completely relieved of Meng Yinan.

After the docking of the "Buzhou Mountain" Aerospace Port was completed, Meng Yinan officially became a member of the Aerospace Harbor, and as an outsider, Lin Mo had no need to continue to stay here.

He was very satisfied with the launch this time, and the simulation training was still a little different from the real launch.

"Okay, I'll send you!"

Wei Yunyi lightly shook her head, naturally understanding what Lin Mo meant.

Rather than being asked out after a while, it is better to leave on your own initiative, and it is already very rewarding for the space agency to be able to do one step.

The two turned around and just left, on the big screen in the hall of the command center, an astronaut took out an octagonal metal box from the package bag delivered in, its edges and corners were wrapped with cushion rubber, and on the metal surface in the middle, a line of laser-etched letters was clearly imprinted: "searl-effectgenerator"——
