January 19, 2017, 11 p.m. PT. National Aeronautics and Space Administration, Space Junk and Satellite Orbit Monitoring and Warning Center.

Two staff members on duty are sitting next to the monitor, happily chatting about last night's barbecue party, one eyebrow fluttering, and the other laughing, as if they were on vacation.

Of course, the complicated work that originally required manual calculations has long been replaced by electronic computers, and the intensity of their work has naturally decreased a lot, at least there is enough time to chat and discuss who a certain hot girl last night prefers.

Tick tick.

A prompt sounded out, and a message from the International Aerospace Orbit Resource Management Network popped up on the interface. This means that in the near future, another artificial satellite will be launched or scrapped, and it will become space junk, or it will become space junk. News like this happens almost every week, and the two have long been surprised.

The person holding the cup clicked on the prompt and looked at it twice, then showed a puzzled look.

"George, come and see this."

He pointed to the prompt on the screen and said to the other person.

"Huaxia Changguang Telemetry Satellite Orbit Change Notice? Oh gag! What are they doing? The young man named George slid over in a swivel chair and looked at the screen in amazement. At least in his memory, no low-earth orbit satellite in China has made an orbit change plan during its service.

"Why is there no detailed target track?" George asked the man holding the cup, at least the other party, who was older than himself, might have dealt with a similar situation.

"Military purposes!" Martin changed his wandering state, tossed his coffee cup aside, and began to retrieve detailed information about the satellite.

"Huaxia Xichang Satellite Launch Base, launched on October 19, Changguang telemetry satellite. The optical precision is... Well?? Looking at the data on the screen, Martin froze. These parameters are clearly a civilian meteorological and geological observation satellite. What orbit will a civilian satellite become?

However, the work habits he has developed all year round still made him back up the data records completely and transmitted them to the Houston in-orbit satellite dispatch and command center.

At the same time, the space departments of various countries that received this news carried out similar operations, but the degree of attention attracted was different, after all, the reconnaissance capability of a civilian telemetry satellite is much smaller than that of a military exploration satellite. As far as the current direction of orbit change is concerned, it will only change its orbit more and more, and there is no possibility of collision with other satellites in orbit.

At 12 o'clock at noon in Lao Mei, it was midnight in China, and Nie Peng, who had difficulty sleeping, was lying in his bedroom, tossing and turning, unable to sleep. The reason is still due to the story told by Jiaying's father.

Microscope? Helping others? Do I want to focus on solving the problem at the root cause? But where is the root cause? Anyone can encounter a dilemma, how to find the root cause of this kind of thing?

Obviously, Jiaying's father's prompt solved a lot of confusion for him, but what followed was a more in-depth thinking about the issue of "charity". He was now like a man trapped in the dark, already smelling a hint of the fragrance outside the door, but he couldn't find where the door was.

What is it exactly?

Thinking about the problem and thinking of going crazy, Nie Peng simply sat up from the bed, held the edge of the bed against the empty wall, and took a deep breath.

This is one of the preparations he makes every time he encounters a problem.

After a few deep breaths, he went to the table, took a blank piece of paper, and began to refine his thoughts.

First of all, the people he expects to help, as well as the poor people mentioned in Jiaying's father's story, are a group of people who are in trouble and are powerless to change their current situation.

So, what are the characteristics of this group of people, and what are the commonalities?

Nie Peng picked up the pen and began to write: Poor, hungry and cold, war, displaced...

A lot of these words have been written, but there is only one thing to sum up: underdeveloped.

So what can you do?

He changed a blank sheet of paper and began to write again: space environment, pharmaceuticals, astronautics, moon landing...

The more I write, the clearer my thoughts become, and the tip of the pen gradually begins to connect these words, and the words become rapid and powerful:

Technology! Aerospace technology! Derivative Technology! Tech Tree! New Industry 。。。

Yes, the problem has been found. He touched the closed door.

If before he only knew how to help every victim he saw ignorantly, then now he finally knows what he is pursuing, to paraphrase a very classic sentence, the greater the ability, the greater the responsibility.

To put it more clearly, now he has put himself on a new level to think, and all the questions about the construction of the base seem to have suddenly become clear, why do it? For whom? Why did he do it?

Do you need a reason for these things?

If necessary, then the construction of the lunar base is a project that can truly fundamentally promote social development, and such development will inevitably lead to the improvement of the living standards of all mankind.

Of course, such a project naturally cannot be completed by him alone, and it is not realistic.

What he needs to do now is to base the lunar base as a catalyst for scientific and technological progress, providing excellent practical opportunities for academic research, including the study of the moon and other planets, physics and astronomy, biology and medical sciences.

After all, the moon landing project required high precision and reliability unprecedented in history. In the face of such strict requirements, people have to look for new materials and new methods; developing better engineering systems; with a more reliable production process; Make the working life of the instrument longer; There is even a need to explore entirely new laws of nature.

Through these new technologies, we will drive new industries to deal with hunger, disease, food and water pollution, and environmental pollution.

This is the root of the dilemma, and his moon base is the driving force that can make a qualitative leap forward in technology.

When my mind came to this, everything suddenly became clear.

Twelve points satisfied with his life goal, he folded the paper in front of him, full of a sense of relief and relaxation, this feeling struck suddenly, couldn't help but make him angry, so he quickly climbed into bed and prepared to go to bed, but in a trance remembered that he seemed to have forgotten something, and after a little pondering without impression, he was no longer entangled, and turned around and fell asleep.

And something he forgot was already fermenting in Jiaying's heart at this time, the box of "little raincoats" she bought was quietly hidden in the wardrobe by her at this time, and the expectation of changing from a girl to a woman couldn't be hidden no matter what, she felt that she was about to explode, it was a desire born from her heart;

It is the restlessness of the heart mixed with hormones;

It is a palpitation that cannot be supplied;

It's an itch.
