At the same time, on one side of the hibernation chamber, a small storage compartment appeared.

Pang Xuelin took out a bag of gelatinous food from it, opened it, and slowly squeezed it into his mouth.

This is the jelly-like food that relieves hibernation syndrome.

The so-called hibernation syndrome refers to a condition that humans are prone to exhibit after waking up from a long period of hibernation.

Clinical manifestations include poor appetite, listlessness, skin ulceration, mucus in the mouth and nose, and difficulty breathing.

The main reason is that before human beings enter hibernation, although they have emptied the food in the intestines as much as possible, there will always be food residues that have not been completely digested and absorbed, and these food residues are accumulated in the stomach and intestines, and these food residues rich in nutrients are the medium of pathogenic microorganisms and breed a large number of pathogenic bacteria.

Although most germs will die after entering the cold state, a small number will enter a state of hibernation like humans, and when humans wake up, they will also wake up.

Newly awakened humans have low immunity and disease resistance and are susceptible to infection with these bacteria, which can lead to the appearance of hibernation syndrome.

And this bag of food has the effect of replenishing nutrients and cleaning up intestinal bacteria.

Although Pang Xuelin has been modified by genetic optimizer, these problems basically do not occur, but just in case, this step still cannot be omitted.

Subsequently, Pang Xuelin pushed open the hatch of the hibernation chamber with his hand and slowly floated out of the hibernation chamber.

Considering the limited power that the solar sail can provide, the Ark-1 spacecraft was designed to follow a modular and minimalist model, simplifying the structure of the spacecraft as much as possible, reducing the use of electronic and electrical equipment, and increasing the number of common parts.

For example, the doors of each compartment of the spacecraft are purely mechanical and can be opened manually.

For example, the spacecraft does not have a centrifugal gravity system, there is no complex electronic circuit system, the equipment in each compartment is relatively independent, and the overall appearance and function of each cabin are relatively similar, with backup parts and food reserves, which is convenient for surviving in the universe for a period of time even if it is separated from the spacecraft in an emergency.

In addition, taking into account the ship's material reserves and equipment reliability, every ten years, two crew members (husband and wife) will wake up and spend one to two years maintaining the entire ship.

Over the past 30 years, two groups of crew members have awakened to maintain Ark 1.

Of course, in order to prevent accidents, Pang Xuelin also left MOSS as a backhand.

Once the crew members of the ship have something else in mind, MOSS can take over the entire ship.

This point, even Mu Qingqing is not very clear.

Therefore, this time, although the Ark spaceship was close to the Centauri α, it would only wake up Pang Xuelin and Mu Qingqing, and the others were still asleep.

In this way, the life of Ark One will be greatly extended.

Pang Xuelin estimates that the Ark spacecraft may be able to detect eight to ten star systems in the future.

But this is only an estimate, and no one is sure what kind of accidents will arise during this adventure.

Pang Xuelin grabbed the handrail of his hibernation cabin, and with a gentle push, his whole body flew silently to another hibernation cabin like fluttering.

In the hibernation cabin, Mu Qingqing was still like a sleeping beauty, closing her eyes tightly.

Pang Xuelin did not hesitate, and gently pressed the wake button on the side.

Laugh at......

A white mist was injected into the hibernation cabin, and Mu Qingqing remained motionless, still in a deep sleep.

Pang Xuelin is not surprised, considering the body's ability to bear it, the hibernation awakening process will last for a period of time, and this white medicine mist will be inhaled into Mu Qingqing's body step by step in the next twenty-four hours, gradually reviving her body functions.

Pang Xuelin let go of the handle of the hibernation cabin and slowly floated towards the exit of the hibernation area.

In addition to the huge solar sails, the main part of the Ark-1 spacecraft is composed of nine octagonal structure cabins and a cylindrical command and control module.

The octagonal chambers form the shape of a lotus flower, each forming eight different functional areas.

The eight functional areas are connected to the transition module in the middle part, and the transition compartment is connected to the cylindrical command and control module.

The structure of the entire spacecraft is simple, and each compartment can be detached from the spacecraft, with the ability to survive independently in space.

Pang Xuelin opened the hatch of the hibernation area and entered the transition cabin.

The transition module is equipped with some fitness equipment, such as bicycles, tension machines, treadmills, weight machines, etc., to prevent the astronauts' long-term life in space from causing muscle relaxation.

These devices have undergone a certain degree of modification and are very different from those on Earth.

Pang Xuelin did not stay too much in the transition cabin, but went straight into the cylindrical command and control cabin.

In the command cabin, the screen of the command console glows blue, and in front of the console is a huge porthole made of high-strength special optical materials.

The starry sky outside the porthole is bright, and Proxima Centauri is hidden in the depths of the sea of stars, and there is no way to distinguish it with the naked eye.

At a distance of more than 36 trillion kilometers, this red dwarf star is no different from an ordinary star to Pang Xuelin unless it is observed with a special shipborne optical telescope.

At present, the speed of Ark-1 is close to one-tenth of the speed of light, and it will take at least a month to get close to Proxima Centauri.

As for the unmanned probe that was released as early as ten years ago, it is estimated that it will take another ten years to enter the orbit of Proxima Centauri because of the continuous deceleration.

By that time, Pang Xuelin and the others would have long since left the Centauri α and headed for Sirius.

Pang Xuelin sat down in front of the accusation table and said, "MOSS, help me retrieve the logbook of the past thirty years and the communication records with the earth!" ”

"Understood."

Soon, two folders appeared on the screen in front of Pang Xuelin's eyes, one was the navigation log, and the other was the communication record.

The logbook mainly records the flight of the ship over the past thirty years.

This amount of data is extremely huge, and Pang Xuelin naturally will not read them one by one, but with the assistance of MOSS, he will screen out some navigation logs for browsing.

In the logbook, not only the overall flight of the spacecraft is recorded, but also the corresponding maintenance status.

Ark-1's solar sails cover an area of up to 100,000 square kilometers, and during the long journey of four light years, there will always be interstellar dust and possible meteorite groups.

Although the nanomirror film itself is very strong, there are always cases of accidental breakage.

In the logbook, several repairs performed by the first four awakened men were recorded.

Overall, Ark 1 is in good condition, and even if there are some accidental collisions or damages, it is within the redundancy of the system, and basically does not exceed the expectations when it set off.

After reading the logbook, Pang Xuelin focused on the communication record.

The huge area of more than 100,000 square kilometers of Ark-1's solar sail makes it a natural super antenna, and also makes it possible for Ark-1 to communicate with the Earth over long distances.

For the past thirty years, Ark 1 has communicated with Earth at regular intervals.

In the beginning, the communication latency was very short, and it was possible to transmit a round trip in a few hours.

Gradually, this communication began to extend to days, months.

Up to now, it will take at least eight years for the news on Earth to receive feedback from Ark One.

Pang Xuelin first checked the official communication information.

Communication with the space sector is lackluster.

Most of it is the course information recorded when the spacecraft passes through space.

Of course, there are also some new discoveries.

For example, the most significant discovery was the discovery of an ice giant with a mass slightly smaller than Uranus when Ark-1 crossed the Kuiper Belt.

With an orbital period of more than 1,000 years and more than 300 astronomical units from the Sun, this ice giant is considered by the scientific community to be the ninth largest planet in the solar system.

This made Pang Xuelin a little surprised.

The so-called Kuiper Belt was first proposed by the Dutch-American astronomer Gerald Kuiper, who believed that there was a belt of ice material at the edge of the solar system, and this area was named the "Kuiper Belt" in honor of Kuiper's discovery.

The Kuiper Belt is a doughnut-shaped ring of ice around the Sun that extends from 30 to 55 AU (astronomical units) of Neptune's orbit. The farthest can reach more than a thousand astronomical units.

There are thousands of ice bodies larger than 100 kilometers (62 miles) in the Kuiper Belt, with an estimated trillion or more comets, and most short-period comets, which orbit the Sun for less than 200 years, originate in the Kuiper Belt.

Scientists have previously found that the orbits of some objects in the Kuiper Belt do not match the calculations, so it is speculated that there is a large gravitational object in the Kuiper Belt, which affects the orbits of some objects in the Kuiper Belt.

The discovery of Ark 1 can be regarded as a real hammer.

In addition to this discovery in the Kuiper Belt, Ark 1 also roughly measured the diameter of the Oort Nebula in the solar system.

It also allows human astronomers to have a deeper understanding of the origin and evolution of the solar system.

Most of the official communications are the exchange of these scientific data, and the rest of the information is basically private communication.

Among them, there are more than 100 that belong to Pang Xuelin, and most of them are video materials.

Pang Xuelin clicked on the top one according to the year and time, and the figure of the water baby appeared in the picture.

August 2015.

"Lin Wazi, time flies so fast, in the blink of an eye, you have all set off for three years, since you went into hibernation a year ago, my heart feels empty. Everything is fine at home, I have taken Uncle Mu over to live, my mother had a gallbladder removal operation some time ago, and the doctor said that the diet should be light in the future......"

The memory of thirty years ago slowly emerged in Pang Xuelin's mind, and the water baby in front of him was no different from the memory.

After reading the information of the water baby, Pang Xuelin found that there was another message in August 2015, and after clicking on it, it turned out to be Liu Qi.

"Brother Pang, it is estimated that it will be thirty years before you see this video again, haha, I don't know what I will become in these thirty years. Now the reform and split of Transwarp Group is still continuing, the transition is very smooth, and everything is going according to the process we designed back then. You once said that the short-sightedness and greed of capital may destroy the ecology of the industry, and after you left, a lot of bullshit happened, but fortunately, Old Man Ren, my father, and Uncle Ni are still there, and some people can't make any waves......"

July 2018.

Shui Wazi: "Lin Wazi, Professor Chen Wenyuan is gone, and he was very peaceful when he left, but he kept thinking about you and Qingqing, and I hope you are all well." Oh, I almost forgot to tell you something, Wanying was pregnant again last year, and she just gave birth to a pair of dragon and phoenix fetuses to me two days ago, my mother is very happy, but I keep remembering you......"

April 2019.

Liu Qi: "Brother Pang, it's time to talk to you again, I have donated all my shares in Transwarp Group, this is a real naked donation, donated to the Hope Education Foundation you established." Of course, I still keep the property that my father left me, haha, I'm not a saint after all, and I still want to leave something for my children. In recent years, the country has developed well, and the investment in education has also been much higher, and now the Hope Education Foundation has shifted its focus from primary and secondary school students in poverty-stricken areas to educational equity. We have put forward a plan to pass on hope to the next generation, and through financial support, we will support teachers from prestigious urban schools to teach in primary and secondary schools in poor areas in the central and western regions, so as to narrow the education gap between urban and rural education, and between poor and wealthy areas, so that more people can have the opportunity to attend top universities......"

June 2025.

Shui Wa: "Lin Wazi, I don't know what to say?" My mother left last month, and Uncle Mu also passed away two days ago. When Uncle Mu left, he kept talking about you and Qingqing, although he has been happy like an old naughty boy every day all these years, I know that he has always remembered you in his heart......"

January 2027.

Liu Qi: "Brother Pang, in a blink of an eye, it has been fifteen years since you set off, and I am also old, my father left last month, and when he left, he took my hand and said, our greatest luck in this life is to meet you, I hope I can see you again in this life, at that time I estimated that I was already seventy or eighty, and I don't know what you will look like." Scientists say that hibernation technology can delay aging, sleep for decades, time is like stagnating, and now there are many wealthy people in society who want to go to the future through hibernation. The government is also discussing the expansion of hibernation technology, and I was still a little excited, but I thought about it, birth, old age, sickness and death, human nature, all of them are at this age, and I still think about what is the meaning of these......"

……

After a long time, Pang Xuelin finally pulled the video to the last one.

This video was sent four years ago, and Ark One only received it last month.

2038, September.

Pang Xuelin clicked on the video, and in the picture, Shui Wa and Liu Qi appeared at the same time.

Both of them are full of gray hair, and although they seem to be well maintained, their spirits are not as good as before.

In the video, Shui Wa was the first to speak: "Lin Wazi, I guess you will be able to see this video when you wake up, Brother Liu asked me to come to the south to play some time ago, and I came over with Wanying." My son is married, he works on Mars with his daughter-in-law, and I took a spaceship trip to Mars last year, and I kind of understand why you chose to make such a trip...... To be honest, I really envy you......"

After Shuiwa finished speaking, Liu Qi continued: "Brother Pang, I didn't expect that in the blink of an eye, I am over seventy, and communication experts will not be surprised, I will be able to receive your response in eight years, I am really looking forward to it." Over the years, there has been a lot less discussion about the Ark Project on Earth, and last year it was a little hotter because we received a message from the second group of awakened crew members. The earth has changed so much over the years, and Transwarp Aerospace has become the world's largest space construction contractor, which you probably didn't expect. Now that human beings are developing the moon and Mars, and the nuclear fusion project has also broken through, think about the time when we first met, and then look at this era, unconsciously, I and the water baby are old......"
