After 65 hours of flight, the Magpie Bridge changed its maneuver three times and accelerated twice, and finally arrived near the apogee of the second lap.

At this time, the Magpie Bridge was about 128,000 kilometers away from the Blue Star and about 246,000 kilometers away from the Moon.

The gravitational slingshot effect of Blue Star begins to act on the Magpie Bridge. The effect of the gravitational slingshot is actually not like a slingshot, but rather like a catapult.

The planet's gravity pulls the spacecraft to rotate at high speed. When it reaches the critical point, the spacecraft only needs to accelerate slightly to break free from the constraints of gravity. At the same time, it uses this centrifugal speed to accelerate to fly to the vast universe.

This is how Magpie Bridge is thrown out by the gravity of the Blue Star and flew towards the calculated direction, that is, the direction of the moon orbit.

In the cockpit of the spacecraft, Yang Liming looked at various data and exchanged views with Ye Yadong and Zhang Feng from time to time.

Through the window above the cockpit, you can only see a dark starry sky. The pictures of the universe we often see are colorful stars in the sky.

But in fact, if you really stand in a vacuum and look out over the vast sea of ​​stars, you can rarely see stars except for the dazzling fireball.

This is actually because in the vacuum environment of the universe, there is no large number of gas particles, and light diffraction will not occur. Humans can only observe visible light, and other electromagnetic waves and light waves cannot be seen.

The starry sky pictures in daily books are artificially synthesized pictures formed by various scientific instruments such as infrared telescopes and then computer-processed and rendered.

In a dark universe, he flew silently to the moon, and the Magpie Bridge seemed a little lonely.

Exploring this unknown vast universe always requires some warriors who can endure loneliness to overcome obstacles for mankind to advance to interstellar civilization.

The high-speed flight of Magpie Bridge, with the support of gravitational slingshot, accelerated its engine again, reaching 10.5 kilometers per second.

Although the route has some oblique angles, the Magpie Bridge needs to fly about 280,000 kilometers to enter the moon's intersection orbit.

However, this distance is only about 7 hours and 24 minutes left for the Magpie Bridge, which has a speed of up to 10.5 kilometers per second.

"Report, everything is normal on the way forward."

"Reported that the connection has been completed with the Moon-Watching Satellite."

Yang Liming nodded: "Entering autonomous driving, Zhang Feng, you go and rest first."

Zhang Feng checked the area he was responsible for and asked the captain to check it again. After confirming that it was correct, he floated to the living cabin.

In daily work, cross-checking each other's operating equipment is also one of the lessons learned from the aviation industry.

Many mistakes often come from negligence and carelessness in the isolated deep space.

The moon-watching satellite mentioned by Zhang Feng just now is four special satellites, namely the moon-watching 1-communication relay satellite, the moon-watching 2-communication relay satellite, the moon-watching 3-navigation satellite, and the moon-watching 4-navigation satellite.

These four moon-looking satellites are located at the Gralaning point L1 of the Blue Star and the Moon. To be more specific, they are on the halo orbit of the Gralaning point L1 of the Blue Moon.

The Gralaning point L1 is a relatively fixed dynamic equilibrium point, which is at the equilibrium point between the gravitational force of the Blue Star and the Moon. It is about 320,000 kilometers away from the Blue Star and about 65,000 kilometers away from the Moon.

As for the role of the moon-watching satellite.

As the name suggests, two communication relay satellites are responsible for communication between the Blue Star and the Moon, while two navigation satellites assist in navigation between the Blue Star and the Moon.

These four satellites were just launched in March this year, with the purpose of assisting the establishment of the lunar space station and the lunar base.

During the uniform cruise, Yang Liming took the time to contact the ground command center again and reported some situations.

In a blink of an eye, six hours and fifty minutes passed, and there were only 34 minutes left to reach the intersection of the moon's orbit.

Zhang Feng, who had been resting for more than six hours, woke up by the alarm clock. He picked up his mouthwash and cleaned his mouth, scrubbed his face with special wet wipes, and then returned to the cockpit.

At this time, the spacecraft began to brake and slow down. The three of them calmly controlled the Magpie Bridge. After 80 minutes, they successfully reached the intersection.

"Start change the track."

"receive."

After about five minutes, the Queqiao completed the maneuvering orbit change, successfully entered the lunar orbit, and then began to fly around the moon.

According to the original plan, the Que Bridge will be circling the moon's orbit for 2.7 times, and will stay on the lunar equatorial plane orbit 310 to 320 kilometers away from the moon's surface.

The reason why it operates in such a low orbit is mainly because the moon's gravity is relatively weak, and this operating altitude can meet the normal orbital flight of the space station.

After more than ten hours of orbital change, the flight orbit of the Que Bridge was finally successfully maintained on the lunar equatorial orbit from 313 to 318 kilometers. The Que Bridge was an average of 186 minutes and orbited the moon for a circle.

After arriving at the designated track area, Captain Yang Liming began to divide the work: "Yatong, it's your turn to rest, and we will leave the other work."

"clear."

After cross-checking the equipment, Ye Yadong went to the living room to rest.

Yang Liming and Zhang Feng are busy in an orderly manner. Don’t think that you can rest assured when you reach the moon orbit.

In fact, after reaching the moon orbit, the real test has just begun.

The moon does not have a powerful natural protective magnetic field, which leads to solar storms and cosmic rays, which can drive straight in.

The reason why humans have been slow to build synchronous orbit space stations is that these areas are easily disturbed or even destroyed by solar storms without the powerful magnetic field protection of the Blue Star.

In order to ensure safety, the Queqiao number began to deform, changing from "I" type distribution to "L" type distribution.

Then, through the robotic arm, two round and special space capsules were assembled on both sides. The capsule was a strong magnetic field protection capsule and could become a small strong magnetic field, namely the Faraday cage.

The magnetic field protection chamber does not use solar energy, but uses carbon 14-nuclear decay batteries, each equipped with 420 kilograms of carbon 14-nuclear decay batteries.

It can supply stable and high-density electrical energy to superconducting magnetic field generators. This small strong magnetic field can protect an elliptical area with a radius of about 160 meters and resist most solar storms, especially those charged particles, which are easily deflected away.

Of course, this is not enough. In order to enhance safety, other power supplies in the Changong Space Station can mobilize a large part of the energy used as magnetic field generators when necessary.

The magnetic field generator itself also designed the allowance for overclocking operation. After all, the spacecraft has three times the redundant design, and only the energy supply can keep up, the magnetic field strength of the magnetic field generator can be increased by up to 4.5 times.

After assembling the magnetic field protection chamber, Yang Liming tested the effect of the strong magnetic field preservation layer, and there was no problem.

They began to lay solar panels and assembled other space capsules one after another.

The Changong Space Station in the first phase has a current weight of 117.3 tons. It currently carries 8.4 tons of three satellites that have not been launched, as well as the remaining surplus fuel of about 32 tons.

Subtracting the weight of the surplus fuel and satellites, the real weight of the Changong Space Station is 76.9 tons, including the Queqiao spacecraft, core compartment, docking compartment, and material compartment.

And after coming to the moon, two strong magnetic field protection chambers and one backup energy chamber were assembled one after another.

There are 6 cabins and 1 ship in total, so many space capsules can be arranged. The main body is beneficial to the improvement of material technology, which has improved the comprehensive performance of the space capsule by about 160% compared with the past, but the weight is reduced by about 57%.

There are two small cabins inside the Magpie Bridge spacecraft, namely the cockpit and the living cabin.

In fact, the function of the Queqiao spacecraft is not only to bring the first part of the Changong Space Station to the moon, but also to the purpose of emergency escape.

Once there is a problem with the Changong Space Station, astronauts can return to the Blue Star through the Queqiao spacecraft, or return to the Tiangong Space Station, or the Guanghan Palace base used to rescue the moon surface.

After more than a week of busy schedules, the initial space capsule and equipment arrangement of the Changong Space Station was completed.

Yang Liming drifted through the narrow living compartment and entered the core compartment. This is the real core of Changong Space Station. The computers, control systems and so on of the space station are all in the compartment.

Unlike the dirty and messy inside the International Space Station, Changong Space Station and Tiangong Space Station are in line with each other, and the internal layout presents a square pattern.

He came to the core compute module, pulled out the hidden keyboard, and entered a series of instructions.

Zhang Feng's voice sounded from the headphones: "Captain, the orientation calculation is completed."

"Received, launched on Moon One."

Behind the space station's material compartment, a satellite was ejected.

There are three satellites around the moon, which are used in the field of communication relay. After all, Changong Space Station will fly around the moon, and the moon is tidally locked by the blue star. The front face is always facing the blue star, but the back is unknown.

If there is no relay satellite, once the Changong Space Station runs to the back of the moon and is blocked by the moon, it will cause the Changong Space Station to lose communication connections with the Blue Star direction.

Therefore, the arrangement of communication relay satellites has become an indispensable solution at present.

The three moon-circling satellites are orbiting about 1360 to 1830 kilometers away from the moon's surface. Together with the communication satellite at Glarang point L1 is enough to ensure that the Changong Space Station and the future Guanghan Palace Base and Blue Star preserve uninterrupted communication.

After the moon-circling satellite was arranged, Yang Liming returned to the cockpit.

Through the ultra-high-definition camera of the space station, he and Zhang Feng clearly saw the back of the moon. For more than a week, they have been able to see this lonely world half of the time every day.

There are more craters on the back of the moon, and it is precisely because of the existence of this natural satellite that blocks a large number of meteorites for the Blue Star.

They finally had free time and cooperated with the ground command center to carry out some lunar scientific research projects.

On the other side.
