"Yan Gong, the recoverable rocket in X-space is about to be launched, and the members of the group are watching the live broadcast together, do you want to come?

Knocking on the door and asking about Yan Guoping's right-hand man Wang Zhiwei, as the first batch of aerospace professionals recruited by Infinite Future Company after the implementation of the "Thousand Talents Plan", Wang Zhiwei is like a fish in water in the group.

At the beginning, after he finished his aerospace doctoral degree in the United States, because he was unwilling to join the American nationality, all the well-known laboratories and aerospace companies in the country closed the door to him, and even the project team with teachers did not allow him to participate because of confidentiality requirements.

After entering the group, he devoted himself to the study of technology, and soon showed his R&D talent in the electric propulsion system, and is now the head of the electric propulsion engine project team of the Space Division, playing an important role in the process of digesting the black technology reserves.

The live broadcast that Wang Zhiwei mentioned was made up by X Space, a private space company in the United States. This company is also a high-tech star enterprise in the United States, claiming to have mastered the technology of repeatable launch rockets, this launch test is to show this technology, and the rocket used for display this time is also the latest model, it is said that the carrying capacity has been improved a lot compared with the previous model, the topic has been hyped by the global media for several days, and today's launch site has been broadcast live by several major television networks in the United States.

As a competitor, the people in the Space Business Division are of course also paying attention to this matter, and the company has a special application for satellite signals, which can watch the mainstream TV network channels in various countries around the world, and the departments that need it have access to it. In the middle of the night, the managers and technical backbones of the business unit remained in the office, just to watch the live broadcast for the first time and discuss with each other. Otherwise, there is no need for everyone to get together, just brush their work tablets in the single dormitory.

"Okay, I'll come right over." Yan Guoping agreed, put down the work at hand, and came to the department's conference room. The technicians had already transferred the satellite signal to the virtual projection equipment, projecting it above the open space in the middle of the large round table of the conference, and a circle of people sat around, and the best viewing effect could be obtained from any position. There are also many technicians who have no place to sit, so they stand around the table, and the conference room of the University is full.

The launch time is not far away, the picture is divided into two screens, half of which is the picture of the rocket launch site, and the rocket of 1+2 (main rocket + booster rocket) has been standing quietly on the launch stand. The other half of the screen is the host talking with a person who looks like an expert in suits and leather shoes. The grandstand signs, using the signal of the United American Television Network, as for the English dialogue, it was not a problem for everyone present.

The moderator was starting the conversation: "Dr. Max, you have just introduced the advantages of rocket recovery technology, and now that the rocket is about to be launched, can you please introduce the rocket itself to the audience?" ”

"Of course, gladly." The expert who was invited seemed to be well prepared, and he opened his mouth to come, "The rocket to be launched today is the most powerful rocket designed and manufactured by mankind since Saturn V in the Apollo era." Its carrying capacity will reach an unprecedented 63.8 tons, which is equivalent to being able to send a 737 passenger plane into space. You see, the tallest rocket in the middle is 230 feet (note: 70 meters), plus the two booster rockets on both sides, a total of 27 high-power engines are equipped, and can produce 2,260 tons of thrust during the takeoff phase, which is the largest rocket thrust since the end of the Space Shuttle era. ”

The moderator continued to guide the conversation and set the mood, "Wow, that sounds very exciting. So, Doctor, what's the point of us building such a big guy that can take civil airliners to outer space? ”

The expert had a "Are you an idiot" look on his face, "Some people will say that there is no point in making this, it has nothing to do with our lives. But I want to tell you that most of the new technologies that have emerged in modern society in the past 30 years have come from the scientific research results created during the space race. If the rocket is successfully launched and successfully recovered, it means that our new technology can significantly reduce the unit price per kilogram of cargo sent into space, and successfully occupy the global satellite launch market. Even in the near future, space cities and moon bases in science fiction movies may become reality, and the living space of human beings will expand indefinitely. ”

"How far can it be reduced?"

"As far as I know, NASA currently spends $15,000 per kilogram of cargo into space, and if the rocket can be reused, I estimate that the cost can be reduced to less than $10,000."

"Incredible, that sounds cool. Is it okay to say that if all goes well, we are far ahead of other countries in this area? ”

The expert hesitated, "China is catching up quickly in the aerospace field, especially in cost control projects, and the Chinese are particularly talented." In the past two years, there is a company in China that has made a new breakthrough in the electric propulsion engine, although there is no public data, but I suspect that the unit cost may be less than 5,000 yuan. ”

The host looked incredulous, "Really? Are you sure? China? I really like to eat Chinese food, and Zuo Zongtang chicken is particularly delicious. ”

The expert's expression was very serious, and he was about to continue to say something, but was interrupted excitedly by the host, "Look, it's time for the countdown, and the big guy is about to take off." The countdown counts start popping up on the screen.

It is not surprising that most of the people in the conference room of the Space Division have overseas study experience, and it is not surprising that Americans are notoriously indifferent to other countries, and some people's impression of China is still stuck in 50 years ago. It's okay, we accumulate grain, slowly become kings, and once we become famous and known to the world.

The foreplay has passed, and finally got to the point.

As the countdown ends, the rocket ignites and launches into the air.

At 2 minutes and 33 seconds, the two booster rockets separated.

In 3 minutes and 07 seconds, the first and second stages of the main rocket separated.

At 3 minutes and 49 seconds, the fairing was thrown, and the second-stage rocket successfully entered orbit with the cargo.

Everyone is focused, and the next thing is key:

At 7 minutes and 58 seconds, two booster rockets appeared on the live broadcast screen again, and the two rockets were only about 100 meters apart, and landed vertically in the designated area at the same time.

At 9 minutes and 33 seconds, a signal was sent from an unmanned barge in the Atlantic, and the first stage of the main rocket also landed vertically on the barge deck as planned.

There was jubilation and celebration in the picture, but it was quiet in the conference room. Yan Guoping stood up, "We are improving, and the opponent will not stand still." It's getting late, so let's get here first, let's make preparations, start with the parts we are responsible for, and have a meeting tomorrow morning to make a comparative analysis. ”
