In a large conference room in Wanda Plaza, a kick-off meeting for the formal operation of the porous liquefied DAC carbon dioxide trap transformation project was held.
First, the top leader of Jinling City took the stage and gave a brief speech on the entire project.
It expresses that Jinling City will carry out urban transformation projects in the next few years and strive to build Jinling City into the first "artificially controlled" livable city to benefit the people.
For Jinling City, due to the cheap electricity brought about by the first implementation of controllable nuclear fusion technology, it has been continuously attracting population and talents from surrounding cities and even all over the country in recent years.
However, the reasons for whether large cities can retain their population and talents are not only the main wage level, but also many other factors, such as relatively cheap daily necessities, food, clothing, housing and transportation, convenient transportation and other factors that can be artificially controlled.
There are also factors such as whether the city is livable, climate temperature, etc.
And these are often things that cannot be changed by humans.
But now, Jinling City already has a ‘card’ that can be played. That is to create a livable city through urban transformation and artificial control of the city’s temperature.
Perhaps in a short period of time, it will be difficult to see noticeable effects before urban transformation takes shape on a large scale, but as an "urban characteristic" that attracts talents, it is still enough.
After the top leader of Jinling City came to the stage to express blessings for the urban reconstruction project, Xu Chuan also went up to say a few words, expressing praise and blessings for the livable city Jinling intends to build.
In fact, regardless of whether the city leaders here came up with the porous liquefied DAC carbon dioxide capture urban transformation project because of their face, they still have the idea to build a livable super city.
No matter what the reason is, if this kind of project is implemented, it will benefit tens of millions of ordinary people living in this city.
Even large-scale greening and other actions in cities to cooperate with porous liquefied DAC carbon dioxide traps are beneficial to urban residents.
For this kind of project that benefits the general public, he doesn't feel disgusted when he goes up to support it, and he is even quite happy to stand up.
But for him, he is more interested in the detailed trial operation data of the porous liquefied DAC carbon dioxide trap than in transforming a city.
After declining the invitation from the leaders of Jinling City to have lunch with him, Xu Chuan returned to Xinghai Research Institute with these experimental data.
Although it was said that the porous liquefied DAC carbon dioxide trap deployed on the high-rise building outside was officially put into operation today, the trial operation data collected before was enough for him to understand some situations.
"Siyi, help me hand over these data to the Information Research Institute, and ask Zhou Ji to arrange a few people to build a mathematical model, and conduct a simulation with reference to the climate data of the entire Jinling City in the past ten years to see how the urban transformation project will affect Jinling.
Urban Impact.”
"Focus on two aspects of calculation. One is the temperature impact on the city after the reduction of carbon dioxide. Calculate Hexi New Town and the entire Jinling City separately."
"The second is to calculate the impact of the collector on the urban heat island effect warm air flow when driven by the maximum power, and calculate how many large carbon dioxide traps are needed to affect 30% or 30% of the entire city. Fifty, seventy-five percent of the node air flow."
In the assistant room, Shen Shenyi took the USB flash drive that saved the data and quickly wrote down a few key words in a shorthand notebook with a pen.
After confirming that there was no problem, she raised her head and asked: "Is there any other information that needs to be added? Professor."
Xu Chuan thought for a moment, shook his head and said, "No more for now."
He originally wanted the Information Research Institute to simulate and calculate the impact of using a porous liquefied DAC carbon dioxide trap on the Martian atmosphere.
However, the current content of the Martian atmosphere and greenhouse gases such as carbon dioxide and methane, as well as the carbon dioxide and other resources that may be stored in the earth's crust, are still uncertain.
Although NASA's Perseverance and other Mars probes have previously collected some data, those data are not very detailed and complete.
If you really want to use carbon dioxide traps to transform the atmosphere of Mars, you may have to wait for the Fuyao space shuttle to send back complete and detailed data.
Calculating it now doesn't make much sense.
If the amount of dry ice and carbon dioxide contained in the soil is too large, everything will have to be overturned.
"Good professor."
Shen Shenyi nodded, responded, and then continued: "In addition, Director Weng Yunzong from the Aerospace Research Institute came here just now and said that he would like to ask you to go there when you come back, and it has something to do with the Fuyao space shuttle. "
Hearing this, Xu Chuan had a thought in his mind. He calculated the time and it seemed that it was almost time.
Nodding, he said: "Okay, I understand."
...
Without even entering the office, Xu Chuan turned around and walked towards the Aerospace Research Institute.
Knocking on the door of Weng Yunzong's office, he walked in with a smile.
In the office, Weng Yunzong, who was staring at the computer screen, looked up when he heard the movement. When he saw Xu Chuan, he stood up with a smile.
"Academician Xu, you are back."
Xu Chuan smiled and nodded and said hello: "Well, I just came back. Before I even entered the office, I heard that you had something to ask me. Has Fuyao reached the orbit of Mars?"
Weng Yunzong stood up with a smile and made tea himself, and replied: "Well, we have successfully reached the low-Earth orbit of Mars and are starting to launch relevant detection equipment."
"In addition, the first batch of ultra-high-definition images of Mars as a whole have been sent back. Do you want to take a look?"
"Of course!" Xu Chuan replied with interest.
After making two cups of tea, Weng Yunzong turned on the computer and retrieved the Mars photos that had been sent back.
"These photos have been sent to you via email a few hours ago, but I think you haven't had time to see them yet."
Xu Chuan walked over, took over the seat and sat in front of the computer.
In the folder he clicked, pictures covering the entire page caught his eye.
I touched the mouse and double-clicked the first picture. This was a picture taken hundreds of thousands of kilometers away before the Fuyao space shuttle reached the orbit of Mars.
Yellow and tawny rocks and soil, as well as the white ice caps at the north and south poles of Mars, form this complete map of Mars.
It seems to be different from the Mars that most ordinary people have in mind, or from the pictures of Mars seen on the Internet.
In the impression of most ordinary people, the soil on the surface of Mars contains a large amount of iron oxide, which turns red after being exposed to ultraviolet rays for a long time. It should look like a red, cold planet.
Most of the Mars-related pictures on the Internet, including those taken by the Hubble Telescope and other astronomical telescopes, basically have similar colors.
But the photos taken by the Fuyao space shuttle are somewhat different.
In this picture, the surface of Mars is not that red, but more yellow and tan. The iron oxide in the soil on the surface of Mars does not seem to appear reddish.
Of course, this does not mean that there are problems with the photos taken in the past, nor does it mean that the photos taken by Fuyao are wrong, nor does it mean that the situation on the surface of Mars has changed.
This is just a difference caused by imaging through different shooting technologies.
Picture after picture flashed through Xu Chuan's eyes, from far to near. The number of pictures taken by the Fuyao space shuttle during its approach to Mars was actually not that many.
This is mainly affected by shooting technology.
It is completely different from the conventional shooting method. Ordinary people usually take photos with their mobile phones and cameras at the scenery. As long as you move quickly or set up automatic photography, you can get hundreds of photos in one minute.
Photos are a breeze.
But in distant space, taking a high-definition picture of a planet often takes a lot of time.
For example, the Hubble Telescope, the core principle of taking high-definition pictures of the planet is to collect and focus light through the optical system, and then convert it into electrical signals and record them.
It adopts the Ritchie-Chretien-Cassegrain optical layout. The incident light is first reflected from the primary mirror to the secondary mirror. The secondary mirror again reflects the light through a small hole in the primary mirror to reach a group of shared scientific instruments.
focal plane to generate an image.
The Fuyao space shuttle is equipped with photography equipment such as the space telescope's advanced survey camera, wide-field camera, and imaging spectrometer.
These devices all work within a specific wavelength range and work together to collect optical data on Mars, which is then converted into electrical signals to form pictures.
And another important factor is ‘exposure control’.
Although there are enough stars in the starry sky, it is still too dim for the camera.
Almost all astronomical telescopes require long exposure times to collect enough photons. The longer the exposure time, the more photons are obtained, and the clearer and more perfect the photo will be.
This is also an important reason for limiting the number of ultra-high-definition Mars images taken.
However, as the distance to Mars gets closer, when the conventional optical ultra-high-definition camera array enters the working range, the number of photos taken will increase dramatically.
Among these photos, Xu Chuan is most interested in the pictures of Mars' two levels.
Like the Earth, the rotational orbit of Mars also has a rotational inclination and is close to the Earth.
The Earth's rotational inclination angle is about 23.5 degrees, while that of Mars is about 25.19 degrees.
However, because Mars does not have a huge satellite like the Moon to maintain the stability of its rotation axis, the rotation inclination angle will change, ranging from 13 degrees to 40 degrees, with a period of tens of millions of years.
What interests Xu Chuan is the size of the ice caps at the north and south poles of Mars!
In one of the panoramic views of Mars, he could clearly see a large area of white on the backlit surface of the south pole of Mars.
It is similar to the ice caps at the North and South Poles of the Earth, but unlike the water ice caps on the Earth, the ice caps at the South and North Pole of Mars are mainly composed of carbon dioxide and methane.
Its quantity will largely determine how humans will immigrate to Mars in the future.
