Chapter 432 Lunar Letter ([-])

2020 6 Month 1 Day.

At 20:17 Beijing time, ten hours have passed since the Conqueror [-] spacecraft left the new Kaohsiung space station.

Ma Wu has closed the live broadcast room, because of the very long distance, the communication delay is already very obvious, and he has to concentrate on commanding the spacecraft.

Ma Wu looked at the flight coordinates of their spaceship and the distance from the moon, and calmly ordered Zhu Gang: "Start the deceleration engine and reduce the flight speed."

"Received." Zhu Gang immediately started the deceleration engine.

Immediately, the three engines installed in the seven-in-one cabin in the middle were ignited and started, and the Conqueror [-] spacecraft began to slow down slowly.

Why did the Conqueror [-] spacecraft slow down?
Because the gravitational force of the moon is smaller than that of the blue star, this means that its first cosmic velocity is lower than that of the blue star.

According to the relevant calculation formula G*M*m/r^2 = m*(v^2)/r (G gravitational constant, M mass of celestial body surrounded by m, mass of object surrounded by m, orbital radius of r, v velocity.), we This yields v^2 = G*M/r.

月球半径约1738公里，是蓝星的3/11，质量约7350亿亿吨，相当于蓝星质量的1/81。

The first cosmic speed of the moon is about 1.68 kilometers per second, based on: V^2=GM(2/r-1/a), a is the semi-major radius of the orbit of the man-made celestial body, a→∞, the second universe Velocity V2=2.38 kilometers per second.

If the Conqueror [-] spacecraft does not slow down and the gravity of the moon is turned off and cannot capture the Conqueror [-] spacecraft, then the consequence is that the spacecraft flies directly over.

Therefore, the Conqueror [-] spacecraft must reduce its flight speed so that the gravity of the moon can catch the Conqueror [-].

As the deceleration engine exhausted the raging fire, the speed of the Conqueror 5000 spacecraft slowed down more and more until it approached the moon about 1.67 kilometers, and the speed finally dropped to [-] kilometers per second.

This speed is already lower than the first cosmic speed of the moon, and the Conqueror [-] spacecraft has already begun to cut into the orbit of the moon.

"Enter the lunar orbit and start orbiting." Ma Wu calmly ordered.

"Received." Zhu Gang smoothly operated the spaceship and began to orbit the moon.

However, at this time the spacecraft is still about 4200 kilometers away from the moon, and they must move around the moon while maneuvering to approach it.

"Perform the first mobile orbit change."

……

"Perform the second maneuvering orbit change."

"It is reported that the new Chang'e-2400 has successfully decelerated into orbit on the moon, and is currently [-] kilometers away from our side. They are all normal." Qin Hailu said.

"Reply to them."

"receive."

Ma Wu looked at the display screen of the instrument. At this time, their spacecraft was less than 1500 kilometers away from the moon's ground, and they could enter the moon's low-earth orbit only by performing another maneuvering orbit change.

Didi...a burst of alarm suddenly sounded.

[alarm!alarm!There is an object approaching at azimuth 671/159/450, initially detected as an asteroid with a diameter of about 0.4 meters...]
[alarm!alarm!There is an object approaching at azimuth 673/157/450, initially detected as an asteroid with a diameter of about 0.1 meters...]
[alarm!alarm!There is an object approaching at position 677/159/410, at first...]
"Activate the shield immediately." Ma Wu made a decisive decision.

"receive."

After a while, more than a dozen asteroids met them on a narrow road, and Conqueror [-] head-to-head with the asteroids against the shield.

There was a slight shaking, and the monitoring system showed that two asteroids had hit the shield, but these asteroids obviously couldn't shake the condensed matter shield.

About 2 minutes after the impact, Conqueror [-] and the asteroid group completely crossed and passed.

"Turn off the shield, and Hailu will inform Xinchang'e-[-] about the asteroid, and tell them to be careful."

"Received." Zhu Gang turned off the shield system.

"Received." Qin Hailu sent the relevant information to Xinchang'e-[-].

Although the asteroid group had already passed away with their spacecraft, Ma Wu did not take it lightly. These asteroids should be the fragments from the previous WX asteroid (Iron Star [-]).

Regarding their possible encounter with asteroids, the Space Development Committee had long expected that the WX asteroids scattered no less than 20 pieces of debris on the orbit of the moon.

After more than half a year of evolution, there are still about 3 pieces of debris that are still in the orbit of the moon. These debris have become new asteroids. If they are not cleaned up, it is estimated that it will take decades to fall to the moon. ground.

Sure enough, during the third orbital maneuver, Conqueror [-] encountered two waves of asteroid impacts.

"Successfully entered the lunar low-earth orbit of 300 kilometers, the orbital inclination is 12.67 degrees, and the orbiting speed is 1.67 kilometers per second." Zhu Gang finally breathed a sigh of relief.

"Successfully connected to the lunar satellite network, and the communication system is normal."

The lunar satellite network is the positioning and communication system of the Space Development Committee on the moon, which consists of 12 lunar synchronous orbit satellites.

The moon's synchronous orbit satellite is different from the blue star, because the moon is tidally locked by the blue star, causing the front of the moon to always face the blue star, and there is no way for the lunar synchronous satellite to be fixed over an area.

Ma Wu took over the driving of the spacecraft and let Zhu Gang take a rest. Although the Conqueror [-] is part of the lunar space station, it does not carry solar panels.

Because it uses a nuclear fusion battery (miniature nuclear fusion reactor), this nuclear fusion battery is only about 50 kilograms, and the DD nuclear fuel it carries can maintain the nuclear fusion battery for about 5 to 15 years.

Now that there is a stable nuclear fusion battery, there is no need for solar panels. Although solar panels have been improved so many times, they are already very light, but the structure of solar panels is essential. If solar panels are installed, it will Not 50kg weight anymore.

Don’t worry about backups. New Chang’e-[-] also carries a nuclear fusion battery, plus the storage battery and hydrogen generator system of the space station. Even if one of the nuclear fusion batteries fails, it can be dealt with in time.

"Ma team, the new Chang'e-300 has entered the lunar low-earth orbit [-] kilometers, and is approaching us." Qin Hailu reported to Ma Wuhui.

"Reply to them, we're ready for the merge in half an hour."

"receive."

the other side.

The new Chang'e-[-] spacecraft.

"Standing team, the Conqueror 2020 is ready for docking and merging work, and the docking will be in half an hour. The specific time is June 6, 2, 1:06 in the morning." Correspondent Song Quanshenghui reported.

"Reply to Conqueror [-], and agree to dock and merge according to the scheduled time." Chang An ordered meticulously.

"receive."

Half an hour later, the new Chang'e-[-] and Conqueror [-] were slowly connected together, but unlike ordinary space station cabin docking, they did not adopt end-to-end docking, but side-to-side docking.

The 7 cabins in the middle of the two spaceships are connected side by side to form a joint plane of 14 cabins. This is also the advantage of the regular hexagonal cylinder, which can be docked sideways or head to tail.

The airtight hatch at the junction slowly opened, and Ma Wu and Chang An had already appeared opposite, and they shook hands and greeted each other.

"Ma team, thank you for your reminder."

"It's all my family members, you're welcome."

"Is your lunar landing crew arranged?" Chang An asked.

"It's been arranged. Zhu Gang, the co-pilot, and Fang Haibo, the maintenance man, will land on the moon." Ma Wu actually wanted to go, but he had to stay in the lunar space station as the commander-in-chief, so he had to reluctantly let Zhu Gang have the opportunity.

"On my side, it's me and the correspondent Song Quansheng." Chang An is the temporary captain of the lunar spacecraft this time.

"Then let's have a good rest and officially land on the moon at ten o'clock this morning."

"can."
