Chapter 637 Patches
Zhu Rongcheng is slowly rotating in the synchronous orbit of Mars.

The centrifugal force generated by this rotation allows the outermost annular chamber to generate a standard gravity (simulation).

Since the length of the spiral arm has reached 15 kilometers, the gradient difference produced by the rotation is already negligible, and will not affect the life of the new humans and the animals and plants on the earth in the standard gravity cabin.

Although Yin Siyong and others synchronize the state of the robot, they can still feel the pseudo-gravity brought by centrifugal force.

After watching the movie, the group of them visited the botanical garden again.

While admiring the strange plants, a crew member asked in a low voice: "Captain, are we going to return to the moon tomorrow?"

"Back to the Moon? No, we're going to the Kuiper belt."

"Cooper belt? Rapid mode? That's fine." Michelle reacted immediately.

Yin Siyong nodded: "The headquarters wants us to test the rapid mode, and take a tour of Gubai by the way."

"Any other tasks?"

"Of course, we will stay here for one more week. The Mars colony is preparing a batch of satellites, and then we can just throw these satellites into the Kuiper belt."

Michelle was a little surprised: "Throw the Cooper belt directly? No need for specific positioning?"

Yin Siyong shook his head: "Of course not, we are going to take a tour around Gubai, do you understand?"

"Go around? I see."

The so-called walking around is obviously flying around the entire Cooper Belt.

古柏带在传统天文领域中，一般认为其主要的部分，只是从39.5天文单位的2:3共振区域，延展到48天文单位的1:2共振区域。

Moreover, the Kuiper belt is very thin, mainly concentrated in the range of 10 degrees above and below the ecliptic plane, but there are still many celestial bodies scattered in a space several times wider.

In short, it's less like a belt and more like a torus or donut, which means the Kuiper belt has a 1.86-degree inclination to the ecliptic plane.

For the sake of safety, Yin Siyong took a group of crew members on duty on the third day and began to plan the flight route.

Looking at the holographic star map in front of him, Harriet, the navigator of the battleship, pointed to the ecliptic plane of the solar system:

"If we travel along the ecliptic plane, we have to pass through the asteroid belt, Jupiter, Saturn, Uranus and Neptune orbital domains, and there are not a few asteroids in these areas, especially those tiny asteroids."

This is what Yin Siyong is very worried about.

After all, space battleships flying at high speed, even with magnetic shields on them, are not much more protective than ordinary civilian spaceships.

Especially this time they want to test the rapid mode, when the speed of the battleship will soar to 1000 kilometers per second, it will only take 41.6 hours to cover the distance of one astronomical unit.

This speed is much faster than bullets and missiles. Once it collides head-on with other things, the consequences will be disastrous.

There are many cases of civil aviation airliners on the earth. The passenger plane and the bird collided head-on.

The slow speed of civil aviation airliners will be damaged by the impact of relative speed, not to mention the spacecraft with a speed of 1000 kilometers per second.

Regarding this issue, the headquarters has actually had some considerations. At this time, the staff of the Mars colony are adding armor and disposable anti-collision reactive armor to the head of the Qinglong-class space battleship.

But adding armor is actually only a temporary solution, not a permanent solution.

After all, the speed is as fast as 1000 kilometers per second, and no matter how thick the armor is, it will not have much effect.

Therefore, Yin Siyong, who did not want to fail the test, could only find ways to reduce the risks during the voyage.

"The ecliptic route is indeed too risky, I suggest changing the route." Michelle said while drawing another route on the holographic star map.

This route still departs from Mars, but the direction is no longer flying along the ecliptic plane, but flying one astronomical unit (about 1.5 million kilometers) perpendicular to the ecliptic plane in the direction of the North Star.

Then change the flight direction, and fly in the direction of Cooper parallel to the ecliptic plane.

Fly to the top of the Kuiper belt, and then fly vertically down one astronomical unit to enter the interior of the Kuiper belt.

Although this will increase the range by two astronomical units, the safety will be increased dozens of times. After all, the stars in the solar system are generally concentrated in the ecliptic plane, and most of the stars can be avoided by avoiding the ecliptic plane.

Yin Siyong thought for a while, and he also thought this plan was good: "I agree with this plan, but this time the voyage is a bit long, and we need to prepare a few more spare parts for the lithium carbon nanolayer."

"Well, after changing the route, the original distance of 43 AU has increased to 45 AU." Michelle also felt a big headache.

You must know that the distance of 45 astronomical units is only the prelude to this voyage, and there will be a longer mission around the Kuiper belt behind it.

How long is the Cooper Belt?

According to the circumference length formula, circumference length = circle diameter × pi.

It is now known that the distance from the Kuiper belt to the center of the solar system is 39.5 AU to 48 AU, which is the radius distance.

直径即为89～96个天文单位，乘以圆周率3.14，可以计算出古柏带的周长大约为279.46～301.44个天文单位。

According to the limit speed of their Qinglong class, it takes 41.6 hours for an astronomical unit, which takes more than 1 hours, about 500 Earth days.

And this is still the sailing speed at the limit speed. Obviously, after they entered the Cooper Belt, there must be no way to advance at full speed.

In this way, they estimate that they will sail in the Cooper Belt for several years.

Even if the nuclear fusion power system does not need to be started in the inertial flight mode, it is definitely necessary to start the nuclear fusion power system repeatedly during the stop-and-go process.

Yin Siyong and others had to carefully calculate how long the nuclear fusion power system needs to run during the voyage. This data is crucial.

But just when they were troubled.

Carl's team got in touch with them.

In the holographic communication screen.

After listening to Yin Siyong's explanation, Karl replied with a smile: "Your concerns, I can help you solve part of them. This is the magnetic field and tailfield fine-tuning procedures."

Suddenly a software installation package was sent over.

"As long as you insert this patch into the intelligent management system of the nuclear fusion power system, you can increase the service life of the lithium carbon nanolayer by 30-40%."

"Really? That's really great." Yin Siyong breathed a sigh of relief.

But Karl reminded: "Don't take it lightly, this patch is limited to use in areas with relatively small gravitational interference. After you enter the Kuiper Belt, some areas are Neptune's gravitational resonance area, and the patch may fail."

"I see. Thank you Dr. Carl for your reminder." Yin Siyong nodded.

A week passed quickly.

The Qinglong-class space battleship Yin Siyong was on started the final sailing inspection.
