Earth Time, June 2012.

The Kunlun base has been left for China for a long time. After nine months of hard work, the Nuwa spacecraft has been completed.

This is a mutated version of the Kunlun number designed by Huang Ji at the time.

Design concepts and technology have been learned by Chinese scientists, and they have even made improvements based on actual conditions.

Of course, the changes were even worse, and all parameters were completely reduced. The various weapons originally designed were directly abandoned and changed to more precise detection instruments and communication equipment.

The overall size is also bigger, but the materials are cheaper.

This change is actually more in line with the industrial foundation of China. The production time is short and the materials are cheap, so the overall cost has dropped by more than double.

But no matter what, this is the first nuclear-powered spacecraft produced independently by China.

It can carry six people, accelerate to a maximum of 20,000 kilometers per second, and it is more than enough to cross the solar system.

Nowadays, traveling in space is no longer an unattainable luxury.

However, compared to freely exploring the solar system, humans have a heavier task to do compared to colonizing on other planets...reversing the abnormal activities of the sun!

The gamma ray burst has been more than 30 years, but the massive eruption of solar corona in 2012 is already in front of you.

Although this is not enough to exterminate humans, it will destroy the existing society of human beings. Most electronic instruments and communication satellites will collapse and will not be able to conduct any radio communication within at least one year.

Scientists predict that this wave of outbreak will also increase the overall temperature of the earth by six degrees! Entering the extremely hot era, glaciers from both poles will melt on a large scale, releasing a large amount of carbon dioxide.

As global temperatures rise by three degrees, humans can no longer stop the trend of global warming, let alone six degrees?

By then, seawater will flood the continent and terrestrial organisms will be extinct at least 70%. This will lead to the continued increase in the concentration of carbon dioxide in the atmosphere, and the seawater will greatly increase the acidity. Marine dinoflagellates will become extinct, and young fish will not be able to eat. Marine organisms will become extinct within one month, and most of them will die due to hypoxia and acidic water.

This disaster will be no less than any mass extinction in history.

Although human technology can continue to rely on nuclear fusion and not become extinct, this will obviously make people unable to withstand future gamma-ray bursts. Even without gamma-ray bursts, humans cannot accept the devastated world.

Of course, with Zhulong and a guarantee measure, if Zhulong is available, they are not qualified to join the Star Alliance.

Therefore, it is inevitable to prevent this big eruption of the sun.

In any case, human beings do not want to face the dilemma of sharp decline in population and social collapse, and they can only survive.

At this moment, the great powers in the world place their hopes on China, and China place their hopes on this Nuwa ship, which is an action to repair the sky!

"The slowdown has been completed and the Mercury synchronous orbit has been entered."

"No, the solar wind intensity is seriously exceeding the standard! This is 30% higher than our estimate!"

"How could it be so much higher! Increase the power of the magnetic screen!"

The six astronauts on the Nuwa have just slowed down the spacecraft and faced severe tests.

Mercury's orbit is too close to the sun. It has to face the impact of high-energy particles released by the sun anytime and anywhere, and the concentration is much higher than that of the earth.

Technically, there is actually a material that can withstand this solar wind. If used as outer armor of the spacecraft, it will not only be okay if it is bombarded, but it can also be charged.

However, this material is not yet produced by the existing technology in China.

Now that time is tight and the task is heavy, scientists have to settle for the second best, choose cheaper materials and combine them with the magnetic screen module installed on the spacecraft to allow the Nuwa to get close to the sun.

Even though you can get close to the sun, the source may become a problem again.

Magnetic shield is a magnetic field shield that requires energy to maintain it at all times.

The stronger the solar wind, the more energy they need. Although they had a fault tolerance rate of 30% at the beginning of the design, they did not expect that as soon as they came, the intensity of the solar wind was higher than the estimated 30%, and they directly approached the limit.

"This is just the orbit of Mercury! We place colorful stones to the expected coordinates, and must be close to the chromosphere layer, and the intensity there will only be higher."

"The plan cannot keep up with the changes. Captain Liu, we are close to the sun now, and the mission is likely to fail."

Many crew members focused on the parameters while reporting quickly, and cold sweat penetrated their foreheads.

This mission is only allowed to succeed, not fail.

It is difficult for the Earth to build a second spacecraft in a short period of time. Even if it is built, it will only be more difficult than them, because the abnormal activity of the sun is approaching the explosion period, the harder it is to stop it!

This is their first long-distance mission. I didn't expect that they were not going to the moon or Mars, but to come directly to the sun...

Lack of experience, lack of data, and when it comes to it, it is the burden of saving humanity. Even if they are elites with thousands of choices, they cannot help but be nervous.

At this time, the middle-aged man, known as Captain Liu, said calmly: "Prepare to land on the back of Mercury!"

"The solar wind intensity on the dark side of Mercury will be slightly lower, and Mercury is bombarded all year round, and the surface itself is rich in a large amount of helium-3."

"We can try to replenish supplies, and... Lao Zhang, pass on the situation here to Kunlun base."

He made an orderly arrangement, made a decision on the spot, changed his plan, and first landed on the back of Mercury.

Captain Liu, whose full name is Liu Tengkong, is actually over fifty years old this year, but after injecting a genetic drug, he is twenty years younger.

Not only him, but the others are the same, which makes them look very young.

"Don't be nervous. Kunlun base has also considered this situation. We have Plan B, so we will land first." As the captain, he is the Dinghai Shen Needle on the Nuwa and must be calm and calm.

"Yes!" Everyone carried out his order without hesitation, and saw the Nuwa flying around Mercury and starting to land.

It can be seen that the three-kilometer cliff terrain on the surface of Mercury can be seen everywhere, with radial stripes composed of huge craters and volcanic lava.

After finding a relatively flat area, the Nuwa landed steadily.

The performance of this spacecraft is much stronger than that of the space shuttles in the past, such as the arms and fingers, and it is extremely firm, so it doesn't matter if you bump it occasionally.

At this moment, five crew members were wearing their space suits and walked out of the cabin.

Their spacesuits are divided into two layers: the inner and outer layer, the outer layer is the same as before, except that the material is better and lighter. As for the inner layer, it is an advanced light gold nanofilm.

If the outer spacesuit is damaged and only wearing the inner nano film, it can still survive in a vacuum.

"Lao Zhang, stay and keep communicating with the earth."

"The others followed me and went to collect helium-3."

Liu Tengkong drove out a tracked car, which came with a drill bit and a collector, and had a load capacity of more than two tons.

It was unimaginable to put such a large car in the spacecraft before, but it is now easy to achieve.

They drove their cars and galloped on the surface of Mercury, looking at the sky-striking light curtain of the distant horizon, their hearts pounding.

This was their first time to land on extraterrestrial planets. Although they have simulated it on Earth many times, the simulation is a pattern. When it is done on the ground, the depression and shock brought by this environment are unimaginable.

Mercury is very small and the sun is very large, and the distance between the two is close!

Although the place where we are at this moment is a dark side that cannot be shined by the sun, which is equivalent to night, the horizons in all directions are still filled with sunshine!

The whole world is like a dark island, located in the middle of the light column!

Mercury has no atmosphere, so this scene is completely different from the rising sunrise on Earth.

No matter which direction you look, there is a clear wall of light, as if the entire earth is surrounded by thousands of feet of light.

"call……"

"Captain...I...I'm dizzy...I can't breathe..." A crew member said in a rapid breathing.

Liu Tengkong said in a gentle voice: "Close your eyes, don't look, don't think too much, take a deep breath, just treat it as a training ground, and find the right collection location as soon as possible."

Everyone is in good health. Everyone who can be selected to participate in this mission has actually been genetically optimized to reach S2!

However, even so, the mental pressure brought by the tasks and the environment still made them almost crazy, and they couldn't calm down for a long time and couldn't help but think randomly.

Panic and tension made them stretch their heartstrings to the extreme, which almost crushed them and even triggered physiological reactions.

This is a genetic defect in humans. They cannot adapt to space, and even with spacesuit protection, they cannot adapt to it.

Genes have been passed on Earth for countless generations, and suddenly came to Mercury. It felt like it had thoughts and felt the horror from the environment.

Continuously prompt the brain to secrete hormones, train and stimulate the human mind, hoping that they will seek benefits and avoid harm.

However, the human mind is forged by culture and thought. How can we succumb to instinct at this moment? We must complete the task no matter what.

"Here! Helium-3-rich geotechnical layers were detected, with abundance of up to 57%.

"Enough! Collect it now!"

Although everyone panicked, they still collected nearly two tons of helium-3 minerals in an orderly manner and returned to their full load.

When he returned to Nuwa, Lao Zhang had already contacted the earth for three times.

Microwave communication travels at the speed of light, and it takes fifteen minutes to reach the earth and return.

Therefore, the communication between the two sides is concise and concise. Here we explain the situation, give suggestions on the other side, here we express the difficulties based on the suggestions, and then give better suggestions on the other side.

After the two sides communicated fully, a new plan was quickly finalized.

"The gravity generator was removed and transformed into an energy shield module to enhance our resistance to impacts of solar high-energy particles."

"Digging Helium-3 as much as possible on Mercury, and finally abandoning the mining cart and freeing up all the warehouses for fuel reserves."

"The solar activity is much stronger than what is calculated on Earth, and it is getting stronger. According to the latest data estimates, we can open the energy shield and hold it for up to 30 minutes."

"We must put all the colorful stones into designated locations within thirty minutes."

Liu Tengkong talked about the plan seriously, and everyone felt the difficulty of the task.

The original plan was an hour, but now it has been reduced by half.

The sun is changing unpredictable, and everything is considered good, but after an on-site investigation, it is wrong and there is no place to deal with it.

It's thirty minutes, whether you can find the X coordinate is difficult...

Once it cannot be completed within time, humans do not know how many people will die.

The pressure was unprecedentedly huge, making them unable to breathe.
