After finishing the eating broadcast, I chatted with netizens in space for another 20 minutes, and the command center sent the mission instructions again:

"Mars One, this is the ground command center, please reply if you receive it."

"Roger, please." Zhao Yunhan picked up the intercom and responded.

"What is the current situation of Du Xiaosheng and Paul Ackerman?"

Du Xiaosheng's face was solemn, and he glanced at Paul Ackerman, and then nodded to Zhao Yunhan.

Generally speaking, a spacewalk should not be carried out just after entering space.

After astronauts enter space, it usually takes about 2 days to adapt to the microgravity environment during space flight, and then they can choose the "window" of spacewalk according to the space environment outside the cabin.

Because there are many things to pay attention to during a spacewalk, experts on the ground must effectively avoid periods of explosive activity of the sun, radiation anomalies in the South Atlantic, and large space debris through monitoring, so as not to cause harm to the body and safety of astronauts.

Not only that, walking in space, the sun's illumination conditions must also be moderate, otherwise, the huge temperature difference from more than 120 degrees Celsius above zero to more than 100 degrees below zero will pose a huge challenge to astronauts and extravehicular spacesuits.

And these subtle factors have been completely eliminated by the ground.

The first is the adaptation to the microgravity environment, before Du Xiaosheng and others got on the boat, everyone had been trained in the simulation center on the ground for a week.

The reason why Du Xiaosheng and the others were given forty minutes was mainly to adapt to the discomfort of the impact of the rocket launch.

And Du Xiaosheng, as the strongest man in Huaguo, his recovery ability is obviously outstanding.

This kind of discomfort is almost negligible in Du Xiaosheng.

Secondly, there are the various problems above.

These details have been accurately observed long before the launch, and this plan was specially tailored for Du Xiaosheng.

Once in orbit, you will complete the cargo plan, and then with the help of the gravitational slingshot, you will prepare to carry out the Mars flight plan!

Everything is seamless, and what tests it is Du Xiaosheng's strong physique and super high technology.

At this time, the mission soon began to be implemented, with Zhao Yunhan and Christina Asmus in the cabin responsible for monitoring the operation status of the spacecraft, and the other responsible for observing the details of Du Xiaosheng and Baoer's mission execution and giving instructions.

When the two of them were ready, Du Xiaosheng and Paul immediately entered the airlock cabin.

This is rare for fans all over the world to have so many people watching Du Xiaosheng's spacewalk.

At this moment, as the camera moves, the circular door of the airlock chamber slowly opens. This is a metallic-colored cabin, and in the protective cover, there are more than ten spacesuits like Iron Man's suits, among them, Du Xiaosheng and Paul have three each, and Zhao Yunhan and Christina also have two sets in order to deal with the unexpected.

At this time, the inner gate has been isolated from the closed cockpit, and the stamping equipment inside has begun to stamping the inner lock cabin, and standing in the bright airlock cabin, Du Xiaosheng walked to his exclusive spacesuit and began to wear an outgoing spacesuit. Du Xiaosheng has begun to skillfully put on the aviation suit.

Different from the traditional local tyrant's gold-colored aviation suit in the Moth Country, Du Xiaosheng's aviation suit is pure white in color at his request, with a bright red flag on his right chest, a round helmet with a huge field of vision, and a liquid adsorption suction device.

Not only that, in addition to the liquid extraction device, Du Xiaosheng's spacesuit is also equipped with an extravehicular pressure suit, a vacuum shielding heat insulation suit and a backpack-type life support system, and Du Xiaosheng's backpack is a super-large capacity jet mobile device.

This device is extremely heavy, but it is more mobile, faster, and equipped with several small rocket propulsion devices that are detachable, which is as maneuverable as a small spacecraft.

Wearing a spacesuit, Du Xiaosheng did not stop interacting with fans in the live broadcast room.

He said with a smile: "My clothes weigh more than two hundred pounds."

In space, the temperature can reach more than 120 degrees Celsius where the sun shines, and the temperature drops below freezing on the side facing the sun.

The temperature difference of more than 200 degrees requires that our spacesuits must be able to prevent vacuum, thermal radiation and other hazards to the human body, must have the performance of air tightness, pressure, heat insulation, temperature regulation and resistance to micrometeoroids and orbital debris, and must also have a complete life support system and a certain ability to maneuver in orbit. ”

Speaking of mobility, Du Xiaosheng patted his rocket jet device and said with a smile: "As for mobility, when I have the opportunity to show you, I can only say that the cost of Iron Man's suit is only tens of millions, and the comprehensive cost of my spacesuit has exceeded 300 million, which can be said to be the most expensive spacesuit in the history of aerospace." ”

Hearing Du Xiaosheng's words, many fans were a little disdainful.

"Du Ye, this is brainless showing off your wealth."

"In space, there are countless miniature meteorites, and the role of aircraft is not very good at all. Once he is hit by the dust, the clothes that cost hundreds of millions of dollars will also be damaged. ”

"It's easy to fly fast and cool in space, after all, it's difficult to control the direction in weightlessness."

"Everyone is already an astronaut, don't you know more about these aspects than you keyboard warriors? Fool around. ”

……

When fans were talking, Du Xiaosheng and the two had already begun to inhale oxygen and discharge nitrogen.

Seeing that Du Xiaosheng was still out of the cabin with an oxygen mask, many people were a little puzzled.

"The clothes are on, the anchor is a spacewalk, what are you waiting for?"

Du Xiaosheng didn't speak, but the official of the space bureau gave an explanation: "Because there is a certain amount of gas in the human blood, when entering a low-pressure environment, these gases (especially nitrogen) will be separated and form bubbles in the blood vessels."

Excessive air bubbles can compress the internal tissues of the human body, resulting in diseases such as skin itching, joint or muscle pain, cough and chest tightness, and in severe cases, central nervous system symptoms, which is called "decompression sickness" in aerospace medicine.

Therefore, before the astronauts leave the capsule, they must stay in the pure oxygen environment for a certain period of time to release nitrogen in the body to reduce the chance of "decompression sickness".

When Du Xiaosheng saw that the ratio of other gases in his body had been reduced to a minimum, Du Xiaosheng took off the oxygen mask, nodded at Paul, and said with a smile:

"Let's go! Get out of the cabin! ”

Open the safety safety bolt, Du Xiaosheng and Bao Er connected the space operation rope, and then began to relieve the pressure through the pressure relief valve.

After contacting the ground center, Christina replied: "The air pressure in the capsule is close to that of outer space, and the hatch can be opened." ”

As Du Xiaosheng and separately walked out of the cabin door, the live broadcast audience suddenly followed Du Xiaosheng's first-person perspective and saw the beautiful scenery outside the cabin.

Under their feet, the vast cosmic starry sky looked incomparably magnificent.

In the dark cosmic starry sky, the starry sky in the distance was so bright, and under their feet, the blue earth was magnificent, and the bright moon not far away was extremely huge.

Just when Du Xiaosheng was immersed in the beautiful scenery and couldn't extricate himself, the voice of the ground command center came from the earphones:

"Du Xiaosheng, report the situation."

"Reply, the refrigeration system is normal, the body is in good condition, the outer hatch has been closed, and no micrometeors have been found for the time being. Please instruct. ”

Roger, Paul checks the spacewalk equipment and confirms the status of the spacecraft. Du Xiaosheng controls the robot arm to complete the docking of the cargo hold. ”

"Understood."

As Paul took out the small satellite from the airlock cabin and released it into space by remote control, Zhao Yunhan in the spacecraft immediately saw a third-person perspective from the monitor.

This small satellite used around the spacecraft is not unique to Mars One.

In fact, spacecraft from all over the world will use this small satellite to monitor the movement of spacecraft and conduct other scientific observations.

Through the picture transmitted by the small satellite, the ground control center can clearly see that Du Xiaosheng skillfully controls the jet device at this time and flies to the mechanical arm.

In the spaceship, Zhao Yunhan also controlled his arm to join Du Xiaosheng at the same time.

"Be careful." When Zhao Yunhan saw Du Xiaosheng's hand grasping the body of the mechanical arm, she reminded her.

And Du Xiaosheng said with a smile: "No problem." As he spoke, he fastened the seat belt of his body and the robotic arm to his body, and flew towards the cargo that was floating in space not far away.

This is an important step.

During the Mars One mission to the Martian base.

Bringing enough fuel to return home and supplies for a year is a top priority.

These white 'cargo', which was launched into space first, like small rockets, contained the necessary return fuel for Mars scientific experiments, various supplies, fresh water, robotic exploration devices, and even oxygen seeds, base vehicles, and so on.

In the Chinese Moth Project, Du Xiaosheng and others did not land directly on the surface of Mars.

Instead, after reaching the orbit of Mars, the survival items are launched to the surface of Mars.

The robot then uses the robot to see if items such as supplies and launch fuel are working properly.

When it is confirmed, Zhao Yunhan and Paul are responsible for staying in the spacecraft and orbiting around Mars to observe and record all the landforms of Mars.

Du Xiaosheng and Christina landed on the ground and completed the construction of the base.

During the mission, if there is any mishap, the four will not land on the surface of Mars, but will return to Earth with the help of Mars' gravitational slingshot after completing the orbit, and strive to be foolproof.

Therefore, these cargoes are the most important thing in this trip to Mars.

As Du Xiaosheng skillfully controlled the manipulator, dragging small rockets one by one, and reinstalling them to the position of the booster that detached from the orbit after the rocket was launched, Zhao Yunhan and Christina on the side were also nervously observing whether there was any meteorite around them through the radar.

In space, even the high-speed motion of even a very small stone block under gravitational attraction is quite deadly.

Many meteorites are even more dangerous than bullets, and can easily damage astronauts' spacesuits.

And air leakage will be a fatal danger for astronauts in space operations.

"Meteorite was observed, west-north, and it is expected to reach the left side of Du Xiaosheng in three minutes......"

"Pay attention to the ...... of the rope position"

Du Xiaosheng nodded, he had a certain confidence in dealing with the meteorite, which was mainly due to the confidence brought to him by the ballistic warning of the virtual system.

While Du Xiaosheng controlled the manipulator to dock the designated cargo compartments with the spacecraft, Paul was also oiling some key parts of the spacecraft, assembling anchor cables, and installing thermal insulation layers on machines that measure light intensity.

……

Time passes little by little.

In the blink of an eye, about five hours have passed since the two of them left the cabin to carry out the mission.

"How does it feel?" Du Xiaosheng asked Paul.

Paul sighed as he went about his work and said, "Whew! You're such a devil, my 160-kilogram spacesuit has made me feel very uncomfortable, although it is only more than 30 pounds in space, but I still feel that my every move has to resist the resistance of expansion. ”

Du Xiaosheng laughed, the spacesuit he was wearing weighed 220 kilograms, which was a great burden, but it was not a big problem for Du Xiaosheng's physique that was close to level seven.

Watching Paul's hard work, Du Xiaosheng checked the wear and tear caused by the friction of the skin of the body through the internal vision system, and couldn't help reminding: "Pay attention to the wear and tear of the body, and be careful that the elbow area will bleed in a posture." ”

Hearing Du Xiaosheng's reminder, Paul laughed and complained to Du Xiaosheng: "I really hope that my level of controlling the robotic arm is better than yours, hey, my current wrench turns in the opposite direction, which makes me have to spend more energy and strength to maintain my original posture when I work." I feel like I'm doing the hard work three or four times as hard. ”

"Stop complaining, it's almost done." Christina laughed in the cabin.

Just when a few people were chatting easily, Zhao Yunhan on the side suddenly said: "Attention, the radar shows that some meteorite is approaching quickly, you should pay attention to dodge and check the condition of the spacesuit in time." ”

Du Xiaosheng was immediately alert, and he temporarily stopped what he was doing.

The system warning in my head has sounded.

Almost in the next few seconds, several particles of meteorite dust suddenly crossed the pitch-black space, and with the help of ballistic warning, Du Xiaosheng easily avoided it, and controlled the rope connecting the two to dodge a few meteorites as small as fingernails.

However, at this moment, Paul, who was working on the side, pulled the rope that connected the two of them when he was checking whether there was any air leakage in his suit and gloves.

As a result, Du Xiaosheng's evasion action of pulling the rope suddenly turned into a head-on collision, and with a snap, a piece of dust the size of a pigeon's egg hit the rope fiercely.

Under the huge force of the safety rope, Paul instantly fell from the top of the spaceship, and almost at the same time, the part of the rope that was hit was instantly disconnected.

This strength is extremely great, Du Xiaosheng is naturally fine when he connects the mechanical arm, but Paul is miserable, as soon as his body moves, he is instantly pushed into the depths of the universe by this force.

"God, Command Center, I was hit by the meteorite, and the safety rope between me and Du was broken!"

Paul was quite calm, he didn't kick around immediately, and his superb professionalism allowed him to call for help in the first place.
