June 1, 2020.

At 20:17 Peking time, ten hours have passed since the Conqueror-1 spacecraft left the new Kaohsiung space station.

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

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

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

Suddenly, the three engines installed in the middle seven-in-one compartment were ignited, and the Conqueror 1 spacecraft began to slow down.

Why did the Conqueror I ship slow down?

Because the Moon's gravitational pull is smaller than that of Blue Star, this means that its first cosmic velocity is lower than that of Blue Star.

According to the relevant calculation formula G*M*m/r^2 = m*(v^2)/r(G gravitational constant, M is surrounded by the celestial mass, m is around the object mass, r is around the radius, v velocity. ), we get v^2 = G*M/r.

The radius of the Moon is about 1,738 kilometers, which is 3/11 of the blue star, and the mass is about 735 billion tons, which is equivalent to 1/81 of the mass of the blue star.

The first cosmic velocity of the Moon is about 1.68 km/s, and according to: V^2=GM(2/r-1/a), a is the half-long diameter of the orbit of the artificial celestial body, and a→∞, the second cosmic velocity V2=2.38 km/s is obtained.

If the Conqueror 1 does not slow down, the Moon's gravity turns off and the Conqueror 1 cannot be captured, then the consequence is that the ship flies directly over.

Therefore, the Conqueror 1 spacecraft had to reduce its flight speed so that the Moon's gravity could capture the Conqueror 1.

As the deceleration engine emitted a raging fire, the Conqueror 1 spacecraft slowed down more and more until it was about 5,000 kilometers close to the moon, and finally dropped to 1.67 kilometers per second.

This speed is already lower than the first cosmic velocity of the Moon, and the Conqueror 1 spacecraft has already begun to cut into lunar orbit.

"Enter the orbit of the moon and start orbiting." Ma Wu calmly commanded.

"Roger." Zhu Gang smoothly operated the spacecraft and began to orbit the moon.

However, at this time, the spacecraft is still about 4,200 kilometers away from the moon, and they must maneuver and change orbit while orbiting the moon.

"Make the first maneuver and change orbit."

……

"Carry out the second maneuver and change the orbit."

"According to the report, the new Chang'e-1 has successfully decelerated into orbit on the moon, and is currently 2,400 kilometers away from us, and everything is normal with them." Qin Hailu said.

"Reply to them."

"Roger."

Ma Wu looked at the display screen of the instrument, at this time their spacecraft was less than 1,500 kilometers away from the lunar ground, and only one more maneuver and orbit change could enter the moon's low-earth orbit.

DiDi ...... A burst of alarms went off.

[Alert!] Alert! In azimuth 671/159/450, an object is approaching, and it is initially detected as an asteroid, with a diameter of about 0.4 meters...... ］

[Alert!] Alert! In azimuth 673/157/450, an object is approaching, and it is preliminarily detected as an asteroid, with a diameter of about 0.1 meters...... ］

[Alert!] Alert! Azimuth 677/159/410 Objects approaching, first ...... ］

"Activate the shield now." Ma Wu made a quick decision.

"Roger."

In a short time, more than a dozen asteroids met them in a narrow way, and Conqueror 1 faced the asteroid with a shield.

There was a slight shaking, and the monitoring system showed that two asteroids had hit the shield, though the asteroids were apparently unable to shake the condensed matter shield.

About two minutes after the impact, Conqueror 1 and the asteroid swarm also completely staggered.

"Close the shield, Hailu and inform the new Chang'e-1 about the asteroid, let them be careful."

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

"Roger." Qin Hailu sent the relevant information to the new Chang'e-1.

Although the asteroid swarm had already staggered past their spacecraft, Ma Wu did not take it lightly, these asteroids should be the fragments of the previous WX asteroid (Iron Star 1).

As for their possible encounter with the asteroid, the Space Development Committee had long predicted that the WX asteroid had no less than 200,000 pieces of debris scattered in the lunar orbit at that time.

After more than half a year of evolution, there are still about 30,000 pieces of debris left in the lunar orbit, which have become new asteroids, and if they are not cleaned up, it is estimated that it will take several decades before they can fall to the lunar surface.

Sure enough, during the third maneuver and orbit change, Conqueror 1 suffered two more waves of asteroid impacts.

"Successfully entered the moon's low-earth orbit for 300 kilometers, with an orbital inclination of 12.67 degrees and an orbital speed 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 working normally."

The Lunar Satellite Network is the positioning and communication system of the Space Development Commission on the Moon, consisting of 12 satellites in geosynchronous orbit around the Moon.

The Moon's geostationary orbit satellite is different from the Blue Star, because the Moon is tidally locked by the Blue Star, resulting in the front side of the Moon always facing the Blue Star, and there is no way for the Lunar Synchronous Satellite to be fixed over an area.

Ma Wu took over the wheel of the spacecraft and told Zhu Gang to take a break, and although the 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, which is only about 50 kilograms, carries DD nuclear fuel that can maintain the continuous operation of the nuclear fusion battery for about 5~15 years.

Since there are stable fusion cells, there is no need for solar panels, although the solar panels have been improved so many times and are already very lightweight, but the structure of the solar panels is essential, and if solar panels are installed, it is not a weight of 50 kilograms.

As for the backup problem, don't worry, the new Chang'e-1 also carries a nuclear fusion battery, plus the space station's battery and hydrogen generator system, even if one of the fusion batteries fails, it can be dealt with in time.

"Ma team, the new Chang'e-1 has entered the moon's low-earth orbit for 300 kilometers and is approaching our orbit." Qin Hailu reported to Ma Wu.

"Reply to them, we are ready, and we will do the docking merger in half an hour."

"Roger."

The other side.

The new Chang'e-1 spacecraft.

"Chang Team, Conqueror 1 is ready to dock and merge work, docking in half an hour, the specific time is June 2, 2020, 1:06 a.m." Correspondent Song Quansheng reported.

"Reply to Conqueror One, agreeing to dock and merge according to the scheduled time." Chang An instructed meticulously.

"Roger."

Half an hour later, the new Chang'e-1 and Conqueror-1 were slowly connected together, but unlike the ordinary space station cabin docking, they did not take the end-to-end docking, but the side docking.

The 7 compartments in the middle of the two spacecraft are connected side by side to form a joint plane of 14 compartments, which 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 the two shook hands and greeted each other.

"Team Horse, thanks for the reminder."

"It's all your own family, you're welcome."

"Have you arranged for your moon landing crew?" Chang An asked.

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

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

"Then we will rest well, and we will officially land on the moon at ten o'clock this morning."

"Yes."
