Chapter 540

Earth time, June 2012.

Kunlun base has been reserved for China for a long time. After nine months of hard work, the Nu Wa spacecraft has been completed.

This is a variant of the original Kunlun designed by Huang Ji.

The design concept and technology have been learned by Chinese scientists, and they have even improved according to the actual situation.

Of course, the changes were even worse, and the parameters were lowered in an all-round way. The originally designed weapons were abandoned and replaced with more sophisticated detection and communication instruments.

The whole is bigger, but the materials are cheaper.

In fact, this change is more in line with China's industrial base. With short production time and cheap materials, the whole cost has more than doubled.

But anyway, this is the first nuclear powered spacecraft independently produced by China.

It can carry six people and speed up to 20000 kilometers per second, which is more than enough to cross the solar system.

Today, space travel is no longer out of reach.

However, compared with free exploration of the solar system and colonization on other planets, human beings have a heavier task to do Reverse the abnormal activity of the sun!

Gamma ray bursts have more than 30 years to go, but the 2012 solar coronal mass eruption is just around the corner.

Although this is not enough to exterminate human beings, it will destroy the existing human society. Most electronic instruments and communication satellites will collapse, and no radio communication will be possible for at least one year.

Scientists predict that this wave of explosion will make the earth's overall temperature rise by six degrees! In the extremely hot era, the glaciers in the two poles will melt in a large area, releasing a lot of carbon dioxide.

If the global temperature rises by three degrees, human beings can no longer stop the trend of global warming, let alone six degrees?

At that time, the sea will submerge the mainland and at least 70% of the terrestrial life will be extinct. As a result, the concentration of carbon dioxide in the atmosphere continued to increase, the acidity of seawater increased significantly, the marine dinoflagellates became extinct, and the young fish could not eat. Within one month, 90% of the marine organisms became extinct, and most of them died of hypoxia and acidic water.

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

Although with the current human technology, relying on nuclear fusion can continue without extinction, it will obviously make people unable to withstand future gamma ray bursts. Even without gamma ray bursts, humans cannot accept the devastated world.

Of course, there is a candle dragon, and there is a minimum guarantee measure. With the candle dragon, they are not qualified to join the Star League.

Therefore, it is necessary to prevent this great eruption of the sun.

In any case, human beings don't want to face the dilemma of sharp decrease in population and social collapse, and can only survive.

At this moment, the world's major powers are pinning their hopes on China, and China is pinning their hopes on this Nu Wa. This is the action to mend the sky!

"Deceleration complete, mercury in orbit."

"No, the intensity of solar wind exceeds the standard seriously! That's 30% higher than we expected! "

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

The six astronauts on the Nu Wa spacecraft will face a severe test as soon as they slow down the spacecraft.

Mercury's orbit is too close to the sun, so 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 a kind of material that can resist the solar wind. If it is used as the outer armor of the spaceship, it is not only OK to be bombarded, but also can be recharged.

However, this kind of material can not be mass produced with the existing technology in China.

Now time is tight and the task is heavy, so scientists have to take the second place and choose cheaper materials, together with the magnetic shield module installed on the spacecraft, so that the Nu Wa can get close to the sun.

Although we can get close to the sun, energy has become a problem.

Magnetic shield is a kind of magnetic shield, which needs energy to maintain it all the time.

The stronger the solar wind is, the more energy they need to consume. Although the fault tolerance rate of 30% has been reserved at the beginning of the design, I didn't expect that the solar wind intensity will be 30% higher than the estimated, which is directly close to the limit.

"It's just the orbit of mercury! We have to be close to the chromosphere when we drop the penta colored stone to the expected coordinates, where the intensity will only be higher. "

"The plan can't keep up with the change, Captain Liu. We are close to the sun now, and the mission is likely to fail."

While paying attention to the parameters, many crew members reported quickly, with cold sweat on their forehead.

This mission can only succeed, not fail.

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

This is their first long-distance mission. Unexpectedly, they didn't go to the moon or Mars, but directly to the sun

Lack of experience, lack of data, and on the one hand, it is the burden of saving human beings. Even if they are the elites with thousands of choices, they can't help being 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 the year round, and the surface itself is rich in helium-3."

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

He arranged in an orderly way, made a decision on the occasion, changed his plan, and landed on the back of Mercury first.

This captain Liu, whose full name is Liu tengkong, holds the rank of colonel. In fact, he is more than 50 this year. However, after he was injected with a genetic medicine, he was 20 years younger.

It's not just him, it's the same with other people, which makes a group of them look very young.

"Don't be nervous. Kunlun base has also considered this situation. We have plan B. in short, we will land first." As the captain, he is the God of the sea needle on the Nu Wa, so he must be calm.

"Yes All of them did not hesitate to carry out his orders. They saw the Nu Wa orbiting mercury and began to land.

As you can see, the 3000 meter cliff terrain on the surface of mercury can be seen everywhere, with a large number of craters and radiating stripes made of volcanic lava.

Looking for a relatively flat area, the Nu Wa landed steadily.

The performance of this spaceship is much better than that of the previous space shuttle. It's as strong as a finger, and it's extremely strong. It doesn't matter if it bumps occasionally.

Now five crew members put on their spacesuits and walked out of the cabin.

The outer layer is lighter, but it's better divided into two layers. As for the inner layer, it is the advanced light gold nano film.

If the outer space suit is damaged and only the inner nano film is worn, it can also survive in vacuum.

"Lao Zhang, stay here and keep in touch with the earth."

"Others follow me to collect helium-3."

Liu tengkong directly drove out a crawler car with a bit and a harvester, carrying more than two tons.

It was unthinkable before to put such a big car in the spaceship, but now it is easy to realize.

They are driving, galloping on the surface of mercury, looking at the distant horizon of the sky light curtain, heart thumping.

This is their first landing on an extraterrestrial planet. Although they have simulated it on earth many times, the simulation is a model. When they do it on the spot, the pressure and shock brought by this environment are unimaginable.

Mercury is very small, but the sun is very big, and they are very close!

Although at the moment where the sun can not shine on the dark side, equivalent to the night, but the horizon in all directions is still full of sunshine!

The whole world, like a dark Island, is in the center of the light column!

Mercury has no atmosphere, so this scene is very different from the sunrise on earth.

No matter which direction you look, there is an obvious wall of light, as if the whole land is surrounded by the brilliance.

"Hoo..."

"Captain I I feel dizzy Out of breath... " One of the crew members was short of breath.

Liu tengkong said in a warm voice: "close your eyes, don't look, don't think too much, take a deep breath, just think this is the training ground, and find a suitable collection place as soon as possible."

Everyone is in good health. The people who can be selected to participate in this task are all genetically optimized to S2!

However, even so, the task and the mental pressure brought by the environment, or make them almost crazy, the heart can not be calm for a long time, can not help thinking.

Panic and tension, so that their hearts taut to the extreme, which almost crushed them, and even triggered a physiological reaction.

This is a genetic defect of human beings. They can't adapt to space, even with the protection of spacesuits.

Genes have been passed on the earth for countless generations, and suddenly came to mercury. It felt great terror from the environment as if it had thought.

Constantly promote the brain to secrete hormones, regulate and stimulate the human mind, hoping that they will seek advantages and avoid disadvantages.

However, the human mind is shaped by culture and thought. At this moment, how can we succumb to instinct? In any case, we have to complete the task.

"Here! He-3-rich rock and soil layers have been detected, with an abundance of 57%

"Enough! Collect now

Despite the panic, nearly two tons of helium-3 minerals were collected in an orderly way and returned with full load.

When he returned to the Nu Wa, Lao Zhang had already contacted the earth for three rounds.

Microwave communication travels at the speed of light and takes 15 minutes to reach the earth and return.

Therefore, the communication between the two sides is concise and comprehensive. On the one hand, it explains the situation, on the other hand, it gives suggestions on the scheme, on the other hand, it expresses the difficulties according to the suggestions, and on the other hand, it gives better suggestions.

After full communication, the two sides soon finalized a new plan.

"Dismantle the gravity generator and transform it into an energy shield module to enhance our resistance to the impact of solar energetic particles.""Dig as much helium-3 as possible in mercury, and finally abandon the mining truck and free up the warehouse for fuel storage."

"The solar activity is much stronger than that measured on the earth, and it is getting stronger and stronger. According to the latest data, we will open the energy shield and hold on for 30 minutes at most."

"We have to put all the colorful stones into the designated position within 30 minutes."

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

The original plan was one hour, but now it has been cut by half.

The sun is fickle. Originally, everything was considered to be good. As a result, on-the-spot investigation, everything was wrong and there was no reason at all.

Thirty minutes. It's hard to find the X coordinate

And once it's not done in time, humans don't know how many people will die.

The pressure was unprecedented, and they couldn't breathe.
