Chapter 140: 40 seconds
Zhou Cheng knew that he only had 40 seconds at most.
According to research, people know that when exposed to a vacuum environment, the human body will not die immediately, but can survive for about two or three minutes.
However, if you want to avoid any sequelae to the human body, you must put the human body back under sufficient atmospheric pressure within a little more than one minute.
But at this moment, Zhou Cheng must go one step further.
Not only does he need to have no sequelae, he also needs one more thing.
Stay awake.
In a vacuum environment, the maximum time a human body can stay awake is about 40 seconds.
(Some readers have said this is fantasy, but it's not. There are real scientific studies on this topic, backed up by data. It's not fantasy, nor is it just random talk. Interested readers can search for it themselves.)
If it exceeds 40 seconds, one will fall into a coma. Although within the next few tens of seconds, if one returns to an environment with sufficient atmospheric pressure, one can still wake up without any sequelae, but it is obvious that in this vast space, it is impossible for anyone to put themselves in an environment with sufficient atmospheric pressure.
Once you fall into a coma, death will surely await you. There is no second possibility.
During these 40 seconds, Zhou Cheng needs to walk through the unprotected outside the cabin, move about 60 meters from here to the regular exit of the Hope spacecraft, and then re-enter the cabin from there.
Only in this way can Zhou Cheng survive, and survive before the next orbital maneuver, and perform the orbital maneuver in time to prevent the Hope spacecraft from missing the gravitational deceleration of Venus, which would cause the failure of the entire mission.
Zhou Cheng has carried out extravehicular walking missions many times in the past period of time.
But each of those missions was carried out while wearing a space suit and fastened with a safety rope. As long as the mission procedures were strictly followed, there was almost no danger.
But the situation this time is obviously different from the past.
Under the gaze of endless stars, Zhou Cheng's body was like a fish. With a slight push of his arms, he swam several meters and accurately grasped another bulge on the hull of the spacecraft.
The next step is the key to the entire mission.
The reason is simple. This is the longest distance between two grippable bumps on the entire trail.
A full 16 meters.
After gaining power through the bulge here, Zhou Cheng needs to "fly" 16 meters without any contact with the spacecraft body and without any external force, before he can grab another bulge and gain power again.
If something goes wrong, Zhou Cheng will be completely away from the Hope spacecraft and fly irreversibly into deep space.
Zhou Cheng knew that the success of this "flight" was not only related to his own life, but also to the future destiny of human civilization as a whole.
The hard work of so many people and the investment of countless materials may be wasted.
In the past, even the most determined people would have to spend a long time mentally preparing themselves before they had enough courage to take this step.
But at this moment, Zhou Cheng did not do any psychological preparation. He just pushed hard and his body entered the flying state.
It’s not that Zhou Cheng’s psychological quality is stronger, but that he doesn’t have time to do any psychological construction.
We can't afford to waste even a second.
During the short yet long flight, Zhou Cheng opened his mouth slightly, letting the precious air in his lungs escape.
He didn't dare hold his breath or close his mouth, because he knew that doing so would damage his lungs due to the huge pressure difference between the inside and outside.
That's all.
Precious gas was lost, and Zhou Cheng's body was moving forward rapidly in the endless sea of stars.
The bulge in front of me was getting closer and closer.
Zhou Cheng raised his slightly swollen and numb arm, and at the critical moment, he accurately and forcefully grabbed the bulge.
With the arm as the center, the body rotates backward uncontrollably, and a huge pulling force comes from the arm.
Zhou Cheng held on tightly and tried his best to control his body.
After stabilizing himself a little, Zhou Cheng didn't dare to delay. He exerted force again, adjusted the trajectory of his body, and rushed to the next bulge again.
12 seconds have passed.
Zhou Cheng kept adjusting and leveraging the force, moving flexibly between one bump after another.
Finally, with another effort of his arms, Zhou Cheng's body was finally fixed at the hatch.
At this moment, 26 seconds have passed.
He has a maximum of 14 seconds to open the hatch, enter the spacecraft, and then close the hatch.
His brain was almost frozen at this moment, unable to think anymore. Everything he did at this moment was almost entirely based on instinct.
With his slightly swollen and numb fingers, he tapped the control screen and entered the power-on command.
The hatch opened silently, revealing the isolation cabin inside which was also in a vacuum state.
Zhou Cheng pushed hard, and his body smoothly entered the isolation cabin, just like he had left and returned to the cabin in the past.
In fact, without the burden of the space suit, he entered even faster this time.
There are only 5 seconds left.
Zhou Cheng instinctively pressed the button to close the hatch.
This simple action used to take less than a second to complete, but now, completing such a simple task was so difficult.
His veins bulged, his eyes bulged, and his expression was ferocious. He exerted all his strength to close the hatch.
My vision was completely dark, my head felt like a complete mess, and even turning it was difficult. My body was starting to stiffen, and I felt like I was losing control of it.
Consciousness is about to be lost.
But not yet.
There is one crucial final step left.
Release gas.
If the gas is not released, the isolation cabin will remain in a vacuum state. At the same time, only when the gas is released can the inner door be opened.
He was trembling and roaring silently, his vision had turned black in large areas, but he kept staring at the control panel, trying to figure out which button he should press.
He finally raised his stiff and numb arm and pressed the corresponding button.
laugh……
The sound of gas flowing reached Zhou Cheng's ears. The next moment, Zhou Cheng completely lost consciousness.
Time passes slowly.
After an unknown amount of time, Zhou Cheng slowly opened his eyes.
He felt pain and discomfort everywhere in his body.
The arm area hurts especially badly.
He took a look and saw that the clothes there had been carbonized and large blisters had appeared on the skin.
This is probably because it was accidentally exposed to the sun.
This place was too close to the sun. Although the Hope spacecraft was shielding him from the sun throughout his actions, he was still accidentally exposed to the sun.
Fortunately, it was just this one time, with only some burns and blisters.
Otherwise... I'm afraid half of my body will be carbonized due to the high temperature.
