Powerful ion jets ejected from the huge nozzle with a total area of more than ten square kilometers at the tail of the Yuanhang spacecraft, giving this giant spacecraft with a total mass of more than 200 billion tons surging power, pushing it forward. The acceleration process was slowly started.
At this moment, there are almost no other man-made objects in the orbit around Sedna. There is only a piece of debris left on the land of Sedna.
They had either been blown up or loaded onto those spaceships, and they also started the acceleration process and started flying towards the asteroid.
Human civilization has stayed and developed here for nearly a thousand years. A thousand years ago, Zhao Changxing came alone. Now, thousands of years later, Zhao Changxing has once again embarked on a journey with millions of humans.
Because the acceleration was too small, people who were still awake at this moment, including Zhao Changxing, could not feel the existence of the driving force at all.
At this moment, in the large main control room and the first conference room of human civilization, Zhao Changxing and other civilization leaders all looked serious.
Besides them, there were a larger number of scientists, engineers, secretaries, staff officers and others with equally serious expressions.
At this moment, approximately 1.5 million spacecraft operation and maintenance personnel have been scattered throughout the spacecraft, either closely monitoring every fault-prone part of the spacecraft, or carrying various equipment and ready for deployment at any time.
A monitor suddenly sounded an alarm. This means that the pressure in a pressure vessel is too high and is about to exceed a defined threshold. If it continues unrelieved, it is in danger of exploding.
This alarm information was directly transmitted to Xiaoxi's global monitoring and fault handling platform. However, it did not issue the fault. Instead, it directly drove a multi-functional robot to the scene of the incident according to the standard fault handling mode that had been recorded in advance in the database.
After tightening the component connections and solving some program faults, the fault was resolved.
Another information anomaly occurred. This time, Xiaoxi still did not leave the matter to humans to deal with, but directly used robots to solve the incident.
In the entire Yuanhang spacecraft, there are tens of millions of robots that can be driven by Xiao Xi, and their functions cover all walks of life. From troubleshooting, crisis management, life support, power supply, energy, water circulation, etc., everything cannot be separated from the use of robots.
But Xiaoxi is not omnipotent after all. There are always some things that no matter how intelligent artificial intelligence is, it cannot solve them. This kind of thing must be solved by humans on the ground.
This is what it means for the 1.5 million spacecraft operation and maintenance personnel to be ready at this moment.
"There was an unexplained water leakage accident in cabin No. 56115 in Area D. Team 1156 went to deal with it immediately."
"yes."
A message was sent from one of hundreds of secondary command rooms. The corresponding team immediately set off to deal with it.
"There is a suspected heat dissipation failure in the antimatter annihilation reactor No. 7 in Area A. Team 68-79 went to deal with it immediately."
"yes."
The antimatter annihilation reactor is the heart of the entire spacecraft, and there is absolutely no room for surprise. In order to solve this incident, 12 teams with more than 300 people went there at the same time.
In the main control room of the spacecraft, Zhao Changxing and other civilization leaders had a huge screen in front of them. On the screen was a perspective image of the Voyage spacecraft.
At this moment, in the huge perspective image, there were small red dots one after another, flashing like fireworks. At the beginning, the number was very small, but as the entire spacecraft operated at full power, the number of small red dots also increased rapidly.
Later, they even filled up the entire spacecraft densely, with the number almost tens of thousands.
It seems that every part of the spacecraft, from the hibernation room to the storage area, from the life support area to the power area, has malfunctions and alarms everywhere.
This situation is still very scary. If it were seen by someone who didn't know what was going on, they would probably think that the Yuanhang spacecraft was going to explode in the next moment. But Zhao Changxing and others knew clearly that there was nothing surprising about this situation.
This was originally expected.
Because even a small light short circuit failure, a door sensor failure, or even a showerhead being clogged will mark a red dot on the perspective view.
For a giant spacecraft like the Yuanhang spacecraft, an endless stream of glitches is inevitable.
I am afraid that even Moyun Litar civilization cannot avoid this situation, let alone human civilization.
The surge was halted five minutes after the red dots began appearing en masse. The data clearly shows that among the total of about 70,000 faults at this moment, more than 1,000 faults were eliminated in a short period of time after the maintenance robot army controlled by Xiao Xi began to join the battle.
As shown in the perspective view, more than 1,000 red dots have been eliminated.
1.5 million operation and maintenance personnel also joined this encirclement and suppression battle.
New red dots are constantly being born, and red dots are constantly being destroyed. In various maintenance channels within the spacecraft, and in various cabins with or without gravity, robots and humans are running fast.
This situation lasted for 7 days. After seven days, the scale of the alarm was suppressed abruptly, from the peak of about 100,000 to about 30,000.
During these seven days, the speed of the Yuanhang spacecraft only increased by about 2.2 kilometers per second, and it had just broken free from the gravitational field of Sedna.
Originally, the speed should be a little faster than this, but during this period, due to endless failures and alarms, the thrusters were never able to enter full power operation, which resulted in this situation.
Now, the Voyage spacecraft has officially begun its journey towards the inner solar system.
Now, the originally huge Sedna Star has begun to gradually become smaller, and finally turned into an ordinary dim star in the endless starry sky, no longer distinguishable from other stars.
A month passed in the blink of an eye. At this time, the number of red dots dropped again, to only about 10,000. Among them, about 8,000 can be disposed of by Xiao Xi. Only 2,000 need people to go to the field to dispose of them.
At this moment, up to 1.5 million operation and maintenance personnel have begun to hibernate in batches. Because at this moment, there is no longer a need for so many people to stay awake and prepare to repair the fault.
Of course, before leaving the solar system, the number of operation and maintenance personnel will always remain at a high level of more than 800,000. After truly entering the inertial navigation state - generally speaking, the inertial navigation state is the safest - the number of operation and maintenance personnel will be reduced to about 500,000.
Some people are destined to devote the rest of their lives to this journey. Every time someone goes to hibernate, it is a farewell to life and death.
After this meeting, we could never see each other again.
At every collective farewell party, Zhao Changxing tried his best to appear in person, paying tribute to those who went to hibernate and to those who were still awake. Even if he really doesn't have time, he will send other civilization leaders to replace him.
At this moment, three months after setting sail, the total power of the thrusters has finally increased to 80%. In these three months, the Yuanhang spacecraft traveled a total distance of approximately 300 million kilometers.
In the vast sky, in the boundless universe, it is extremely huge, even enough to carry the destiny of an entire civilization, but it is also extremely small, and the Yuanhang spacecraft is advancing silently like cosmic dust.
In this way, more than a year after setting sail, it finally approached Uranus, then Saturn, and then Jupiter.
It didn't stop here at Jupiter. Because it has finally reached its current speed, slowing down would not only take a long time, but also consume a huge amount of energy.
However, before it arrived here, the people who originally lived in the Jupiter system had already completed the disposal of the materials here in advance. They have all boarded the space carrier, the only remaining spaceship of human civilization at this moment, and have already started synchronously accelerating along the trajectory of the Yuanhang spacecraft in advance.
Eventually, the two sides met hundreds of millions of kilometers away from Jupiter.
At this moment, both sides maintain an acceleration of 0.02 meters per square second and remain relatively stationary.
All civilization leaders headed by Zhao Changxing stood on this side of the covered bridge and held a grand celebration ceremony for the people who had finally returned to the main body of civilization.
Supplies from the Jupiter system were also transported to the Yuanhang spacecraft one by one, and other things were transported from the Yuanhang spacecraft to the space carrier.
After a short period of repair, most people were arranged to enter hibernation. Zhao Changxing and others left the Yuanhang spacecraft and entered the space carrier.
The Yuanhang spacecraft still maintained its acceleration state, while the space carrier began to decelerate. In order to save fuel, it also used the gravity of Mars to slow down during the process.
Finally, when it reaches the Earth, its speed has slowed down enough to enter Earth's orbit.
It finally settled into space only a few hundred kilometers away from the earth.
Thousands of years after human civilization left the earth, Zhao Changxing once again returned to this great planet that gave birth to human civilization with all the leaders of human civilization at this moment and the ashes of those who had devoted their lives to the rejuvenation of human civilization. On the planet.
Looking at the huge planet under their feet, which was earthy in color and completely different from the richly colored and magnificent Earth in their memories, Zhao Changxing and the other civilization leaders had a lot of thoughts in their minds.
"Let's go and see our hometown."
Zhao Changxing said.
