Reborn Technology Scholar

sa(first update)

"Qin Yuanqing, are you free tomorrow morning?" Just as Qin Yuanqing was thinking, a voice came into his ears, interrupting his thoughts.

Qin Yuanqing opened his eyes and saw that it was the dean. He immediately smiled and said: "Dean, why didn't you tell me in advance when you came here? Tomorrow, there are no other arrangements for the time being. What's wrong?"

"There is a place that calls for you to go over and help! No, I can only come to your place in person!" the dean said with a smile.

"Oh? Call me by name to come over and help? Do you want the dean to come over?" Qin Yuanqing was stunned for a moment, then asked in confusion: "Where is it?"

The dean smiled and whispered a few letters: "CNSA!"

Qin Yuanqing suddenly realized, sa, no wonder he has this energy!

cnsa is an abbreviation.

Its full name is China National Space Administration!

cnsa was established on April 22, 1993. It organizes or leads activities such as foreign exchanges and cooperation in the aerospace field on behalf of the Chinese government. With the hard work of batches of astronauts, it has completed the Dongfanghong-1 satellite, the Shenzhou series of manned

Aerospace, Chang'e series lunar exploration projects, Beidou series navigation satellite systems, resource exploration remote sensing satellites and other scientific research achievements.

The biggest impression I have on sa is that Shenzhou 5 went to heaven, China's first manned space flight, which symbolized a big step forward for China's space industry and served as a milestone.

At that time, there was a nationwide sensation, and people including Qin Yuanqing and others were singing and dancing in their villages.

only......

Qin Yuanqing didn't remember any interactions with sa.

Qin Yuanqing frowned slightly and asked, "Dean, are you asking me for help?"

"I don't know about this." The dean shook his head and said, "You also know that that place is researching some confidential projects and will not easily leak information to the outside world. You should also know the confidentiality regulations."

Qin Yuanqing nodded slightly.

With the reform and opening up in China, confidentiality regulations in many places have been relaxed. In places such as SA, confidentiality regulations have not been relaxed, but have become stricter. After all, confidentiality is involved there, and once it is leaked, it will cause huge losses to the country.

"Okay, no problem, it's just about the specific time and place!" Qin Yuanqing asked.

When sa asked him for help, Qin Yuanqing would not refuse. After all, this was to help the country, and Qin Yuanqing still had this awareness.

The dean smiled bitterly and said: "I don't know about this. Someone will come to pick you up when the time comes!"

sa, what do you need help from? There are many Chinese talents gathered there. sa, the field of Chinese aerospace and aviation has not yet been opened to private companies, sa, whether it is a launch site or something else.

The next day, early in the morning, not long after Qin Yuanqing arrived at the office, he received a notice that the car coming to pick him up had arrived at the school gate.

At the school gate, an inconspicuous black car stopped. The security department of Shuimu University confirmed with the other party, and then made further inquiries to confirm that there was no problem with the other party's identity.

Qin Yuanqing just got on the bus. As an academician of the two academies, Qin Yuanqing's status is no longer ordinary. His daily life is fine. When encountering such a thing, he needs to confirm again and again to ensure safety.

After all, this world is not peaceful!

As soon as Qin Yuanqing got in the car, he immediately discovered that this car was different from ordinary cars. It had been modified. The glass was bulletproof glass, and with this kind of glass, people could see out from the inside, but they could never see out from the outside.

Qin Yuanqing closed his eyes slightly, while the security personnel next to him pulled down the curtains and the driver started the car.

About an hour and a half later, the car stopped, and the security personnel opened the curtains and said politely: "Academician Qin, we are here!"

Qin Yuanqing opened the car door and stepped out. He was surrounded by steel bars and concrete, and soldiers with loaded guns and ammunition could be seen everywhere.

The security personnel met the soldiers at the entrance and gave a standard military salute. Then the soldiers drove a military vehicle over, asked Qin Yuanqing to sit in the military vehicle, and led Qin Yuanqing into the research base.

The interior of the base is a spiral structure.

At the bottom of a piece of transparent glass protection is a huge piece of equipment.

Dozens of engineers wearing natural-colored protective clothing were busy working in front of the huge equipment.

On one side of the equipment, there were several large red characters printed in standard fonts - Chang'e 2!

sa's logo!

When Qin Yuanqing's eyes fell on those four big characters, his pupils shrank suddenly, and he immediately knew where he was currently. If his prediction was good, it was the R&D base of the Chang'e lunar exploration series under SA.

In 2006, the lunar exploration satellite Chang'e-1 was launched to detect the earth's surface environment, topography, geological structure and physics.

If Qin Yuanqing remembered correctly, the Chang'e-2 lunar exploration satellite will be launched this year and land on the moon in a soft landing for detection. He still clearly remembers the sci-fi patrol vehicle and the automatic robot that made a sensation.

Covering the entire world, it represents another firm step taken by China in the lunar exploration project.

At this time, Qin Yuanqing couldn't help but feel a little excited. You must know that it was a lunar exploration project. Except for the United States, no other country has landed on the moon in so many years.

But now that I have seen the Chang'e-2 lunar exploration satellite at such a close distance, the excitement in my heart is beyond words.

Just as Qin Yuanqing was looking at the Chang'e-2 detector, two old men appeared and walked towards Qin Yuanqing.

"Academician Sun! Academician Ouyang!" Qin Yuanqing saw the two old men and hurriedly stepped forward to shake hands. These two were aerospace giants.

Academician Sun is 81 years old this year. In 1951, he and 29 soldiers were sent to Zhukovsky Engineering Institute to study aircraft engines. After returning to China, he participated in original work on missiles. In 1960, at the age of 31, he was awarded

He also served as the overall chief designer of the model. In 1967, he served as the overall design director of China's first artificial satellite. Later, he served as the technical director and chief designer of China's first remote sensing satellite and the first returnable satellite.

He is also the chief engineer of China Communication Satellites, Meteorological Satellites, Earth Resources Exploration Satellites, and Beidou Navigation Satellites. It is unceremonious that Academician Sun is the "Father of Satellites" of China, and it is his outstanding contribution that

In 1999, the country awarded him the Medal of Merit for Two Bombs and One Star.

Of course, Qin Yuanqing knew about this old man. In 2019, he was awarded the highest national honor, the Medal of the Republic. This is the largest medal awarded by the party and the country for his lifetime contribution to Chinese science.

And Academician Sun is still the chief designer of China's lunar exploration project! Even though he is now over 80 years old, Academician Sun is still exerting his light and heat.

Academician Ouyang, who is now 75 years old, graduated from the Beijing Institute of Geology in 1956. In 1978, he took 0.5 grams of a 1-gram lunar rock sample presented by Brzezinski, the U.S. National Security Advisor during his visit to China.

Research, he was elected as an academician of the Academy of Sciences in 1991. He is also the chief scientist of the lunar exploration project.

Qin Yuanqing did not expect to meet two academicians here.

"Academician Qin, we have encountered a difficult problem this time and need help from mathematicians to analyze and solve it. I have no choice but to invite you over!" Academician Sun shook hands with Qin Yuanqing and said.

Then he took Qin Yuanqing to take a look at the base. The Chang'e-2 satellite is China's second lunar exploration satellite, the first man-made solar system asteroid, and the technical lead star for the second phase of China's lunar exploration project. It is China's first exploration satellite.

The backup satellite for the lunar satellite Chang'e-1 costs about 600 million yuan.

According to the plan, the Chang'e-2 satellite was originally to be launched on October 1 as a National Day gift. However, due to some problems, the launch was delayed.

The problem we are encountering now is that the complete orbit of Chang'e-2 cannot be calculated.

"Academician Qin, we invite you here because we want to ask you to help us calculate the orbit. I wonder if there is any way!" Academician Sun brought Qin Yuanqing to an office area, where everyone used computers to calculate the orbit.

working.

"This...I need some data!" Qin Yuanqing said.

Academician Sun took Qin Yuanqing to a computer, which contained several folders and a large amount of data, including relevant parameters of the Chang'e-2 satellite and a large amount of data on the earth and the moon.

It took Qin Yuanqing more than two hours to find the relevant data, then opened a software, set various parameters, and compiled lines of code by himself.

This includes satellite launch, orbiting the earth, earth-moon transfer, and orbiting the moon.

Qin Yuanqing saved the information, and when he looked at it, he found that seven hours had passed. He was the only one in the entire office.

Qin Yuanqing stood up, stretched, and then opened the door to the room.

It is already evening, but scientific researchers are still working day and night. It is the tireless efforts of these aerospace personnel that have allowed China's aerospace industry to continue to move forward.

"Academician Qin, how is it? Is there any way?" Academician Sun asked when he saw Qin Yuanqing appearing at the door.

"We're close. I've finished the model and set all the relevant parameters!" Qin Yuanqing said with a smile.

"So fast..." Academician Sun was surprised.

You must know that it has only been seven hours since Qin Yuanqing came into contact with the data. Not only have the parameters been calculated, but the model has also been completed.

"Academician Sun, you can go to the computer and have a look!" Qin Yuanqing said with a smile.

Then the two came to the computer. Qin Yuan took inventory of the folders he had created and clicked on the model. The entire Chang'e-2 was launched, lifted off, entered the earth's orbit, moved between the earth and the moon, and flew around the moon.

It is displayed in a very vivid and dynamic way.

"This orbit is the best orbit I calculated. It saves fuel and can run longer. According to calculations, it will return to the earth in 10 years. The remaining fuel will even be enough to land here!" Qin Yuanqing pointed to a location in Inner Mongolia.
