At 2o:17, Peking time, ten hours have passed since the Conqueror 1 spacecraft left the new Kaohsiung Space Station.
Ma Wu has closed the live broadcast room. Due to the very long distance, the communication delay has been very obvious, and he must concentrate on commanding the spacecraft.
Ma Wu looked at the flight coordinates of their spacecraft and the distance to the moon, and calmly ordered Zhu Gang: "Start the decelerator and reduce the flight speed."
"Received." Zhu Gang immediately started the reducer.
Immediately, the three engines installed in the seven-in-one cabin in the middle were ignited and started, and the Conqueror 1 spacecraft began to slowly slow down.
Why did the Conqueror 1 spacecraft need to be reduced?
Because the moon's gravity is smaller than that of the blue star, this means that its first cosmic degree 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, mass of the surrounding celestial body m, mass of the surrounding object m, r surrounding radius, v degrees.), we get
Out v^2 g*m/r.
The moon's radius is about 1,738 kilometers, which is 3/11 of the Blue Star. Its mass is about 735 billion tons, which is equivalent to 1/81 of the Blue Star's mass.
The first cosmological degree of the moon is about 1.68 kilometers per second. According to: V^2=gm(2/r-1/a), a is the semi-major diameter of the orbit of the artificial celestial body, a, and the second cosmological degree V22 is obtained
.38 kilometers per second.
If the Conqueror 1 spacecraft does not slow down and the moon's gravity is turned off and unable to capture the Conqueror 1 spacecraft, the consequence will be that the spacecraft will fly directly over.
Therefore, the Conqueror 1 spacecraft must lower its flight speed so that the moon's gravity can capture Conqueror 1.
As the reducer discharged blazing fire, the speed of the Conqueror 1 spacecraft slowed down more and more, until it approached the moon at about 5,000 kilometers, and the speed finally dropped to 1.67 kilometers per second.
This degree is already lower than the first cosmic degree of the moon, and the Conqueror 1 spacecraft has begun to enter the lunar orbit.
"Enter the lunar orbit and start orbiting." Ma Wu calmly ordered.
"Received." Zhu Gang smoothly operated the spacecraft and began to orbit the moon.
However, the spacecraft is still about 4200 kilometers away from the moon at this time, and they must maneuver around the moon while changing orbit to get closer.
"Carry out the first maneuverable orbit change."
…
"Carry out the second maneuvering orbit change."
"Report, the new Chang'e-1 has been successfully reduced into orbit around the moon. It is currently 2400 kilometers away from us. Everything is normal for them." Qin Hai 6 said.
"Reply 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 lunar surface. Only one more maneuverable orbit change could they enter the moon's low-Earth orbit.
Didi...an alarm suddenly sounded.
[Alert! Alert! There is an object approaching at the position of 671/159/45o. It is initially detected as an asteroid with a diameter of about 0.4 meters...]
[Alert! Alert! There is an object approaching at the position of 673/157/45o. It is initially detected as an asteroid with a diameter of about 0.1 meters...]

"Activate the shield immediately." Ma Wu made a prompt decision.
"receive."
After a while, more than a dozen asteroids encountered them. Conqueror 1 faced off against the asteroids with its shield.
There was a slight shaking, and the monitoring system showed that two asteroids hit the shield, but these asteroids were obviously unable to shake the condensed matter shield.
About two minutes after the impact, Conqueror 1 and the asteroid group completely missed each other.
"Close the shield, Hai-6 informs the new Chang'e-1 about the asteroid, and tells them to be careful."
"Received." Zhu Gang turned off the shield system.
"Received." Qin Hai 6 reported the relevant information to the new Chang'e 1.
Although the asteroid group had already crossed paths with their spacecraft, Ma Wu did not take it lightly. These asteroids should be fragments that broke away from the previous asteroid X (Iron Star 1).
The Space Development Committee had already predicted that they might encounter an asteroid. At that time, no less than 200,000 pieces of debris from Asteroid X were scattered in the lunar orbit.
After more than half a year of evolution, there are still about 30,000 fragments remaining in the lunar orbit. These fragments 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 its third maneuver, Conqueror 1 encountered two more waves of asteroid impacts.
"Successfully entered the lunar low-Earth orbit of 300 kilometers, with an orbital inclination of 12.67 degrees and an orbit of 1.67 kilometers per second." Zhu Gang finally breathed a sigh of relief.
"It has been successfully connected to the lunar satellite network, and the communication system is all normal."
The Lunar Satellite Network is the positioning and communication system of the Space Development Commission on the moon, consisting of 12 lunar synchronous orbit satellites.
The moon's synchronous orbit satellites are different from those of Blue Star. Because the moon is tidally locked by Blue Star, the front side of the moon always faces Blue Star. There is no way for lunar synchronous satellites to be fixed over an area.
Ma Wu took over the driving of the spacecraft and let Zhu Gang take a rest. Although Conqueror 1 was part of the lunar space station, it did 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 keep the nuclear fusion battery running continuously for about 5 to 15 years.
Since there is a stable nuclear fusion battery, there is no need for solar panels. Although solar panels have been very lightweight after so many improvements, the structure of the solar panels is indispensable. If solar panels are installed,
It no longer weighs 5o kilograms.
As for the backup issue, don’t worry. The new Chang’e-1 also carries a nuclear fusion battery, plus the space station’s battery and hydrogen motor system. Even if one of the nuclear fusion batteries has a problem, it can be dealt with in time.
"Ma team, the new Chang'e-1 has entered the lunar low-Earth orbit of 300 kilometers and is approaching our orbit." Qin Hai 6 reported to Ma Wuhui.
"Reply them, we are ready to dock and merge in half an hour."
"receive."
the other side.
The new Chang'e-1 spacecraft.
"Standing team, Conqueror 1 is ready to dock and work. It will dock in half an hour. The specific time is June 2, 2020, 1:06 in the morning." Correspondent Song Quanshenghui reported.
"Reply to Conqueror 1 and agree to dock and merge according to the scheduled time." Chang An ordered meticulously.
"receive."
Half an hour later, the new Chang'e 1 and Conqueror 1 were slowly connected together. However, unlike ordinary space station cabin dockings, they were not docked end-to-end, but side-to-side.
The seven 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 side by side or head to tail.
The airtight hatch of the junction slowly opened, and Ma Wu and Chang An appeared on the opposite side, shaking hands and greeting each other.
"Captain, thank you for the reminder."
"They're all from my family, so you're welcome."
"Have your arrangements for the moon landing crew been arranged?" Chang An asked.
"It has been arranged that co-pilot Zhu Gang and maintenance staff Fang Haibo will land on the moon." Ma Wu really wanted to go, but he had to stay at the lunar space station as the commander-in-chief, so he could only reluctantly give the opportunity to Zhu Gang.
"On my side, it's me and correspondent Song Quansheng." Chang An is the temporary captain of the moon landing spacecraft this time.
"Then let's have a good rest. We will officially land on the moon at ten o'clock this morning."
