Chapter 638 The long journey

Galaxy 8, February 7nd.

The Qinglong-class space battleship completed its final inspection in Mars orbit and received sufficient supplies.

The Qinglong class with a payload of 4.5, in addition to storing a large amount of water resources as nuclear fuel and working fluid, is full of various testing equipment, as well as lithium carbon nanolayers and related raw materials, and there is also a special machine for processing lithium carbon nanomaterials. layer of equipment.

42 crew members are already in place on the cockpit.

Yin Siyong looked at the time: "There are all of them, and they are heading towards the North Star at full speed. The re-acceleration time is 50 hours, and the first stage of the voyage is 1 astronomical unit."

"receive."

"The nuclear fusion power system starts, the 2nd ring is running, the 4th ring is on standby, and the power output is 10%..."

"Route planning completed..."

"set sail!"

The frenzied aluminum plasma is ejected from the main propeller of the Qinglong class, and the plasma reaching 15% of the speed of light leaves an obvious ray of light in the background of the empty universe.

This ray of light erupted from the vent, spreading outward in a funnel shape, and there was no obvious light until 18 kilometers away.

Driven by the reaction force of the plasma propulsion, the Qinglong-class space battleship flies rapidly towards the North Star, and the spaceship presents a state of uniform acceleration at this time.

But Yin Siyong and others in the cockpit did not take it lightly. Among them, 8 radar soldiers in charge of radar monitoring were staring at the holographic scanning screen intently.

As the Qinglong class gets farther and farther away from the ecliptic plane of the solar system, the density of asteroids in the surrounding star area also shows an exponential decline.

The situation in front of him made Yin Siyong a little relieved.

He also looked at the damage of the lithium carbon nanolayer of the nuclear fusion power system.

[During the assessment of local deterioration, it is expected to last for 130-180 days...]
At the 50th hour, the speed of the Qinglong class has been increased to 1000 kilometers per second, and at this time, there are only a dozen hours left for the voyage of one astronomical unit.

Yin Siyong and others, who just changed shifts several times, have been controlling the direction of navigation, and are also carefully scouting the surrounding asteroids.

When approaching the turning point of one AU.

"Start the auxiliary thrusters and start adjusting the flight direction."

"Roger that!"

"The sailing direction has been shifted successfully..."

"Reported flight speed dropped to 936 kilometers per second."

Yin Siyong immediately ordered: "Restart the nuclear fusion power system."

"receive."

As two of the Levi's rings of the nuclear fusion power system were activated, the Qinglong class accelerated again. When the speed reached 1000 kilometers per second, the nuclear fusion power system was turned off again, and the warship was switched to inertial flight mode.

In the empty void, a space battleship flew past at an extremely terrifying speed.

Since it is parallel to the course of 1 AU above the ecliptic plane of the solar system, the asteroids here are very sparse, and the Qinglong class can move forward at high speed without frequent orbit changes.

A distance of 43 astronomical units.

It only took less than 75 days. This speed is relatively powerful among the first-level civilizations.

With the Qinglong class arriving above the ecliptic plane of the Cooper belt.

Yin Siyong frowned at this moment.

Because he saw a lot of asteroids.

The distribution of asteroids in the Kuiper belt is in a donut state, and not all of them are concentrated in the ecliptic plane.

Even in the void that is 1 astronomical unit above the ecliptic plane of the Kuiper belt, the density of asteroids here is dozens of times higher than that of other parallel passages sailed before.

For safety reasons, Yin Siyong could only step on the brakes in advance. At this time, the flight speed of the Qinglong class was only 300 kilometers per second, and it was still declining.

Especially after reaching the turning point, change the flight direction and fly towards the core area of ​​the Cooper belt. At this time, the speed of the Qinglong class is only 273 kilometers per second.

Even at this speed, there are still certain risks, and we must always pay attention to the trajectory of the asteroid within 100 million kilometers ahead.

If the existence of the asteroid is discovered within tens of thousands of kilometers, it may be too late to brake or adjust the flight direction.

"Report, a dwarf planet was found ahead! The distance is 382 million kilometers..."

"What?" Yin Siyong was very surprised. He hurriedly checked the star map and found that there was no record of this dwarf planet in the star map.

Michel turned to look at him: "Captain, what should I do?"

After thinking for a few seconds, Yin Siyong ordered, "Slow down and get closer to that dwarf planet."

"OK."

The secondary thrusters of the Qinglong class were quickly activated, and then began to reverse and decelerate evenly.

And as the Qinglong class and the dwarf planet continued to approach, the situation of this planet was also detected.

The dwarf planet has a diameter of 1036 kilometers, a near-spherical planet, ice-soil composition, a density equivalent to 44.7% of the moon, and an escape velocity of 1.541 kilometers per second. Because it has a low methane and carbon dioxide atmosphere, its reflectivity is extremely low. .

Seeing these detection data, Yin Siyong suddenly realized: "No wonder this dwarf planet has not been discovered."

In fact, there are not a few detectors and artificial satellites of Homo sapiens in the Cooper belt. Currently, there are a total of 1733 detectors and artificial satellites in service in the Cooper belt.

This number seems to be very large, but the problem is that the diameter of the Kuiper belt is close to 10 AU, and the circumference is 270-310 AU.

An astronomical unit is the distance from the earth to the center of the sun.

The 1733 detectors and artificial satellites scattered on the Kuiper Belt are like dropping thousands of sonar detectors into the Pacific Ocean.

Probably the situation can be known, but it is wishful thinking to expect that it can thoroughly understand the details of the entire Cooper Belt.

It may be possible to increase this scale by another ten thousand times.

In fact, after Homo sapiens entered the Kuiper belt, it successively discovered 7 dwarf planets and 42 large asteroids.

Since this dwarf planet has not been discovered, Yin Siyong and others are naturally not polite.

After all, the first group to discover a star is qualified to name the star.

As time went by, the Qinglong class got closer and closer to the dwarf planet, until the speed of the Qinglong class dropped to 5 kilometers per second, and the distance between the two sides was only about 130 kilometers.

"Michelle, launch 3 satellites."

"OK."

The cabin on one side of the Qinglong-class hull opened, and three small launch vehicles flew towards the dwarf planet with artificial satellites.

About half an hour later, the three satellites successfully orbited the dwarf planet and sent back the first batch of images and detection data.

After discussing with the crew, Yin Siyong decided to name the dwarf planet "Courage Star".

Courage Star is not the same as other Pluto dwarf planets, which is why this dwarf planet has not been discovered.

But at this moment, they discovered some very strange data.
