The black tech madman who saves the world

Chapter 177 Hello, Earth (final)
Soon, Tianzhi 1 adjusted its gravitational parameters after trembling violently for a few times, and then entered a calm state.

In the video screen, there is no longer a large shake, and the screen begins to show a vaguely curved perspective of the earth.

"The picture has become much clearer." Sun Zhongyong said.

Chen Mengchuan nodded: "In the stratosphere of the earth's atmosphere, there is relatively little water vapor, suspended solid particles, and impurities. The weather is relatively clear, the light is also very good, and the visibility is very high."

"The current speed has reached 200 kilometers per hour. If you continue to fly for a few minutes, you will start to enter the middle layer. At that time, the speed should start to increase significantly, and the temperature will drop again." Toni calmly Said.

"The atmosphere is interesting. The temperature rises and falls for a while. I learned less about geography before, but now I feel a little regretful." Sun Zhongyong said with a smile.

Several people also laughed, and then Chen Mengchuan gave him a brief science introduction.

"The middle layer is a special layer in the atmosphere. The lower layer is the stratosphere, and the upper layer is the thermosphere. The temperature of the middle layer decreases with the rise of altitude, so there is a very strong vertical motion in the atmosphere, because it is located in the Between the highest altitudes that airplanes can fly and the lowest altitudes that spacecraft can fly, only suborbital rockets can be used to enter, because of this, the mesosphere is the least known layer of the atmosphere to humans."

"And the temperature of the middle layer fluctuates with the seasons, but this fluctuation is the opposite, that is, the temperature is much lower in summer than in winter. In winter, atmospheric gravity waves break up in this A layer conveying westward momentum acts as a westward drag."

"And to balance this drag, the atmosphere has to move meridional towards the poles to get the Coriolis force towards the east."

"This meridional movement from the summer pole to the winter pole causes the atmosphere in the summer pole to rise, adiabatically expands and cools; the atmosphere in the winter pole sinks, adiabatically compressed and heated."

"The effect of this circulation on temperature exceeds the sun's radiative heating, so the temperature of the mesotope is instead the coldest in the summer polar region with direct sunlight, and the hottest in the sunless winter polar region."

"So the mesosphere temperature in summer would be as low as below 100°C, which would be much cooler than the mesosphere temperature in winter."

"In addition, the gaseous particles in the middle layer are very rich. On the earth, millions of meteors enter the earth every day, and then burn in the middle layer of the atmosphere. After the meteoroid enters the middle layer, it will meet with the middle layer The gaseous particles colliding with each other would create a high concentration of iron or other metal atoms. This collision would quickly create enough friction to burn, and then the heat would burn up the falling objects before they could reach the surface. "

After Chen Mengchuan gave Sun Zhongyong a general knowledge, Tianzhi 1 also officially entered the middle layer, and began to accelerate faster, and the speed quickly reached 400 kilometers per hour, and it was still accelerating.

In just a few minutes, Ayu, the artificial intelligence in the Tianzhi No. 1 cabin, reminded: "Lao Xu and Zhang are about to enter the thermosphere, the temperature will increase, and the refrigeration system will start to activate in the cabin. The whole flight will last for 700 minutes. km until entering the final exosphere."

"Okay, Ayu, thank you for your reminder." Xu Zhenglin said. During this time together, the artificial intelligence Ayu has become another close friend of him and his wife. The couple basically no longer regard Ayu as artificial. They are not treated by intelligence, but as a real living person, a real human being who seems to communicate with them and guide them with voice at the other end.

"This is what I should do." Ayu replied with a smile.

Soon, Tianzhi 1 turned off the external camera, and at the same time put away the gravitational outer node that assisted the flight, and the entire spacecraft flew towards the boundless abyss of the universe like a huge bullet.

All the live video images are still being introduced and explained continuously. Although the number of viewers has decreased, there are still a large number of people watching the live broadcast, constantly cheering for the two people on Tianzhi 1.

A few minutes later, a screen in the cabin slowly lit up in front of the two of them.

"Old Xu, Lao Zhang, you are going to be popular this time. More than 20 billion people around the world have seen you two, and people are constantly cheering you on. Let me show you some translated pictures." Ayu said At the same time, many screenshots of comments were placed on the screen, and the slideshow was played quickly.

Xu Zhenglin and Zhang Ying were calm at first, but when they saw the screenshots of these comments, they couldn't help but burst into tears. Although the two of them were about to fly out of this planet, they were not alone. There are still so many people on earth supporting them.

"Ayu, can you convey something to Earth for me?" Xu Zhenglin asked.

"Of course, you can tell me, I will transmit the video and voice to the earth."

"Family partner on earth, I am Xu Zhenglin, and I am currently on the way to the moon. We are very lucky that we have this opportunity to be a member of the moon. We have seen many of your comments on social media and video media. Thank you for your support.”

"Big guys, I'm Zhang Ying, thank you..."

The two were talking emotionally, and the voice was transmitted to the people on the earth through the artificial intelligence Ayu, and under the translation of a group of self-media people, it was quickly transmitted to the whole world...

The flight of Tianzhi 1 is still going on, and the speed is getting faster and faster. It soon broke through 500 kilometers per hour, and the speed is still increasing.

After more than an hour passed, it finally flew to the top of the thermosphere, and then broke through the thermosphere of more than 1 kilometers.

"Old Xu, Lao Zhang, congratulations, you have already entered the dissipation layer, and the flight speed of Tianzhi 1 will soon start to increase significantly. If you feel uncomfortable during this process, please let me know as soon as possible." Ayu said carefully.

"Start speeding up, Ayu." Xu Zhenglin said.

After his words fell, Tianzhi 1 began to speed up quickly, and the speed exceeded 1000 km/h very quickly!

Moreover, as it gets farther and farther away from the center of the earth, the gravitational force of the earth becomes smaller and smaller, and the speed of the spacecraft quickly accelerates to 1500KM/hour in a few minutes!

Then stopped at 1500KM/hour.

"Old Xu, Lao Zhang, Tianzhi 1 has stabilized and can be released for free activities. We will arrive at the moon in 261 hours and start flying in a lunar orbit!"

Ayu's words were not only told to Xu Zhenglin and Zhang Ying, but also to the command department on Earth.

After her words fell, everyone cheered and hugged excitedly!
"There is no doubt that we succeeded!" Chen Mengchuan looked at the picture on the screen, as if he saw the future!

After unlocking the buckle, Zhang Ying walked to the observation window that was slowly opened, and looked at the huge blue planet. A shudder made her tremble all over, and she couldn't help touching the window with tears streaming down her face.

"Hello, Earth..."
