I Can Make Money by Watching Videos

Turn off the air pressure control system of the spacecraft? Is there a mistake? People who know a little bit are stunned. Once the air pressure system is turned off, the astronaut is in a vacuum state. Wouldn't the astronaut's body have problems?

"What is Tang Xiaochuan doing? Don't you understand this bit of common sense? How did he pass the assessment?" Countless people in front of the TV were anxious.

This is what the female astronaut in the cockpit of the spacecraft said: "The audience friends don't need to worry that turning off the air pressure system in the spacecraft will cause problems in our bodies. Under normal circumstances, when a person is in a vacuum state, the internal pressure of the body will be damaged due to the disappearance of external pressure. The pressure is still there, and the seven orifices of the body will ooze blood due to the pressure. If the external pressure is suddenly lost, the body may explode, but we are all wearing spacesuits now. Something is wrong with our bodies!"

Audiences around the world were relieved to hear Han Xiaoyue's words. This is the first time an astronaut has popularized space knowledge to them.

At this time, Zheng Yaoguang's voice came from the headsets of Tang Xiaochuan and Han Xiaoyue, and the audience in front of the TV and the netizens in the webcast room also heard his voice.

"I found the air leak point. On the third window on the left side of the spaceship, a few solder joints fell off and caused the corners of the material to deform. Now the air pressure of the spaceship is decreasing, and the suction force outside the spaceship is also decreasing. This can Make it easier for me to repair the damaged parts!"

Tang Xiaochuan glanced at the data on the big screen, and said to the headset: "The spaceship still has 45 seconds to enter the orbit to switch coordinates. How long will it take to repair the air leak?"

"Quickly, give me fifteen seconds..."

Twelve seconds later, Zheng Yaoguang's voice came from the headset: "The leak has been fixed!"

Tang Xiaochuan reached out and pressed a button, and a mechanical female voice sounded: "Check the airtightness of the spaceship... The test is complete, and the airtightness is normal!"

Tang Xiaochuan breathed a sigh of relief and restarted the air pressure system.

"The air pressure system is restarting... the air pressure is returning to normal..."

Hearing this voice, the hearts of the viewers in front of the TVs around the world and the netizens in the webcast room finally fell back into their stomachs, and many people were sweating from tension on their foreheads and backs.

The family members of the three astronauts were paralyzed on the sofa as if they had suffered a serious illness. Their parents even kept thanking the gods and Buddhas for their blessings.

"The spaceship enters the orbit to switch coordinate points, and the speed is 13.9 km/s"

Tang Xiaochuan immediately pressed a button, and a mechanical female voice sounded: "Turn off the regular engine of the spacecraft..."

Tang Xiaochuan said to Han Xiaoyue: "Xiaoyue is ready to make orbit correction preparations!"

"receive!"

Tang Xiaochuan pressed another button, and the control system made a sound: "Start the ion engine, please perform orbit correction..."

Han Xiaoyue tapped the keyboard quickly with both hands, and the cursor graphic of the spaceship on the big screen turned towards the dotted line little by little. She held a controller in her right hand and moved slowly. This was controlling and adjusting the direction of the ion engine injection port. , in order to achieve the purpose of flight trajectory correction.

"The orbit correction is complete, and the spacecraft has entered the Earth-Moon transfer orbit..."

According to the current technology, the thrust of the ion engine is very small. It generates thrust by ejecting a high-speed particle stream, but the ion engine of Xinghe-1 is obviously not an ordinary product. It is better than the ion engine developed by the Mei people. The power is much stronger.

At this time, Zheng Yaoguang also returned to the cockpit. Tang Xiaochuan and Han Xiaoyue turned around and bumped fists with him respectively to express their congratulations, cheer each other up, and express their appreciation for his successful repair of the air leak just now.

After the celebration was over, Tang Xiaochuan looked at the display screen and found that the air pressure inside the spacecraft was normal, so he started to set the navigation of the spacecraft. Now that the spacecraft has entered the earth-moon transfer orbit, most of the next things can be left to the spacecraft itself control system.

He tapped a few times on the keyboard, and then touched the screen continuously.

"The spacecraft's unmanned mode is activated, and it flies according to the set parameters and predetermined orbit. The estimated time to reach the orbit around the moon is 28 hours, 33 minutes, and 12 seconds!"

"Huh—" Tang Xiaochuan and the three of them breathed a sigh of relief.

After taking off their helmets, Tang Xiaochuan said to the camera with a smile: "After all, I was not very skilled at the first time, but fortunately, the spacecraft entered the earth-moon transfer orbit. In the next 28 hours, we can play happily , the next stop is the orbit around the moon!"

There were glistening beads of sweat on Han Xiaoyue's forehead due to the malfunction just now. When her helmet was taken off, it was clearly seen by the live broadcast room and the global audience.

Tang Xiaochuan unbuttoned his seat belt and said to the camera: "It is said that you can play happily, but it is not true that you can lie down and sleep. Before we can sleep, we came with a scientific research mission. Even The destination is the moon. On the way to the moon, we still need to conduct some scientific experiments in this space without gravity. Time can’t be wasted. After all, such a chance to go to the sky is rare, and it’s all based on money! "

"So the next step is to solve some physical problems, such as going to the toilet, drinking water, etc. Just now, the rocket launch, the spacecraft failure, the orbit change, etc. have made us very nervous. I am a little urgent to urinate now. Let's solve it first. Everyone, don't peek!" After speaking, he lay on his stomach and grabbed an armrest with his hand, floating and moving towards the rear cabin! "

He held the shooting equipment in one hand, grabbed the armrest of the cabin with the other hand, and introduced the places he passed one by one: "This is the telescope observation point, and this is a small leisure room. We can sit here for a while when we are free, but Strap yourself to the chair, or you'll float away!"

"This is the bathroom. You have to pack your stool in a bag yourself, and seal it up after you finish it. Don't throw it around!"

"Urine enters here directly. After rinsing, there is a treatment and purification system below. The urea and some impurities in the urine will be purified and filtered out, and then pure water will come out, so human urine can be recycled! In addition, on the spaceship There is also a bathroom, and the purification system under the bathroom also treats and recycles the water, so I won’t show you the picture of me going to the toilet..."

After Tang Xiaochuan went to the toilet, Zheng Yaoguang and Han Xiaoyue also dealt with physiological problems one after another after preparing for research.

After waiting for the three people to take their positions, Tang Xiaochuan began to assign tasks one by one according to the mission process. He was responsible for collecting the distance between the spacecraft and the earth at each time period, the temperature in space at this distance point and coordinate point, and the number of received cosmic rays. What kind of cosmic rays are they? In addition, he is also responsible for monitoring whether there are radio signals from the depths of the universe, etc.

Zheng Yaoguang and Han Xiaoyue respectively carried out an experiment that can only be carried out in such a gravity environment. Sometimes it is necessary to turn off the air pressure system of the spacecraft or adjust the air pressure; sometimes it is necessary to adjust the temperature inside the spacecraft. Meet the needs of the experiment.

Of course, such experiments can also be done on the earth, but it will cost an extremely high price to build such an experimental environment, and ordinary scientific research institutions simply cannot afford the expensive expenses.

At around 4:00 pm Earth time, Tang Xiaochuan was using the super telescope on the spacecraft to observe space.

"Oh, guess what I saw? The International Space Station. Of course, this space station is far away from us. Come and show everyone what it looks like now!"

After Tang Xiaochuan finished speaking, he connected the telescope to the shooting equipment, and the screen of the global audience and fans and netizens in the webcast room became a lens of an ultra-high-definition telescope.

"I can't see it clearly now, but don't worry, wait for me to debug it...Okay, it should work now!"

All viewers and fans saw a space spacecraft parked above the azure earth in the picture, and many solar panels and other shells and equipment on this huge spacecraft were damaged.

Tang Xiaochuan's voice appeared: "What everyone sees now is the International Space Station. Since last year's stellar storm, it has completely lost contact with the ground, and countries have never been able to contact their respective cabin areas. At present, it seems that It should have completely stopped running, and no one knows what happened to the astronauts on it from various countries, and whether there are still people alive!"

U.S. Space Research Center.

The director of the research center, Hardy, looked at this picture, and after hearing Tang Xiaochuan's words, his heart moved, and he immediately called several scientists for a meeting.

In the conference room, Hardy looked at the scientists and said, "Everyone, how likely is it that our astronauts in the International Space Station are still alive?"

The chief scientist shook his head and said: "It's been more than half a year. If they could repair the equipment and get in touch with the ground control center, they would have done it a long time ago. They haven't done it yet. There are only two points to explain: first, the equipment is damaged to the ground. Unrepairable; second, everyone is dead!"

"Moreover, based on the storage of living materials in the space station, I don't know if they can survive for such a long time!"

Another scientist Julian said: "The equipment of the space station should be damaged. If the electrical equipment cannot work normally, the temperature and air pressure of the space station will not be able to maintain normal. In that case, it is impossible for anyone to survive!"

"But they can hide in the safe house!" Hardy said.

"It's useless!" Julian shook his head, "Without energy supply, the safe house cannot maintain a normal living environment!"

At this time, Hardy finally expressed his thoughts, "If Xinghe-1 is successful, can we contact Huaguo and let them communicate with Feitian Technology Group, and can we check the situation of the International Space Station when we return? , See if there are any survivors!"
