Chapter 579 Want to be an astronaut?
The BFR rocket was successfully launched, and countless people cheered.

Qin Yuanqing also adjusted the news to the Spring Festival Gala. It is estimated that at this time, the Spring Festival Gala program team will be relieved, otherwise the ratings would definitely be terrible.

"Dad~~ Can the United States really succeed in manned landing on the moon? This time their rocket was successfully launched, does it mean that manned landing on the moon can also be successful?" Doudou asked.

"Now the American BFR rocket is equipped with a small life capsule and a detector. At present, the successful launch of the rocket means that it reaches the orbit around the earth. The success of the entire project requires continuous orbital changes from the orbit around the earth to enter. The earth-moon migration orbit, braking and decelerating from the second half of the earth-moon migration orbit until it is captured by the moon's gravity, and orbiting the moon!" Qin Yuanqing popularized the common sense of the operation between the earth and the moon to the two children: "Flying in orbit around the moon is not counted. Success requires landing on the moon. Although the gravitational force of the moon is far inferior to that of the earth, this is also very important. After all, the moon is a celestial body, and its gravitational force cannot be underestimated. There are many technologies involved in this, and any link that goes wrong , will cause the probe to crash into the moon, and the entire launch mission will fall short.”

"There is also the landing point. If the landing point is different from the original setting, the life capsule sent up will not be used in the future, and will not have any effect." Qin Yuanqing said: "And at this point, it can only be considered a success. Half of the time, the probe still needs to leave the moon and return to Earth!"

Seeing that the two children were stunned, Qin Yuanqing directly asked the artificial intelligence to turn on the simulated video of "manned landing on the moon", and then speed up the video.

No matter how you say it, it is not as good as video dynamic simulation.

"This step is to ignite and launch the manned rocket, and use the huge thrust to carry the spacecraft to orbit around the earth, which is what we normally call space,"

"This step is to accelerate the orbit change. Only when the speed is accelerated to a certain speed can the spacecraft escape from the shackles of the earth. This orbit is the earth-moon migration orbit. There are countless earth-moon migration orbits between the earth and the moon. Different migration orbits, The flight time in this orbit is different. For example, the relocation orbit chosen by the "Chang'e" spacecraft is the shortest among all aircrafts, less than a day."

"The speed of the aircraft in the migration orbit of the earth and the moon is very fast. If it flies at this speed, the speed is too high, and the moon cannot be captured. The aircraft will either smash into the moon and crash, or the moon cannot be captured and fly to the universe." Qin Yuanqing pointed out The video is decelerating and braking in reverse: "Therefore, braking is required. The braking is through the reverse engine, providing a reaction force, allowing the spacecraft to decelerate. The spacecraft decelerates continuously until it reaches the speed required for the set orbit, and then Follow the set orbit to fly around the moon!"

"."

For children's education, Qin Yuanqing was very patient, allowing them to see the simulation of the whole process of the manned moon landing of the entire spaceship, and also give pointers.

This is also Qin Yuanqing's condition. If a child from an ordinary family doesn't even have a video, even if there is a video, the parents don't understand the reason.

"Dad~~ When I retire, I want to be an astronaut!" Maodou, who was watching seriously, suddenly said.

"You choose your own path, but you must know that astronauts need to have a very high reserve of knowledge and rigorous training. If you want to be an astronaut, you have to work hard." Qin Yuan smiled lightly.

At this time, the astronauts are definitely the elite among the elites. Every astronaut is trained by the country with huge resources, and the astronauts are extremely outstanding in terms of knowledge reserve and physical fitness.

As a result, some people think that astronauts are much more valuable than gold of their own weight, and they are a well-deserved wealth of human beings!

The two children wanted to become astronauts in the future, so Qin Yuanqing naturally would not object. He felt that the children had their own hobbies and goals, and Qin Yuanqing thought it was pretty good.

Wealth is no more than three generations!
Children and grandchildren have their own children and grandchildren!
These are summed up by Huaxia for a long time. Qin Yuanqing thinks it makes sense. Even he does not think that his children and grandchildren can be rich for generations. Qin Yuanqing thinks that is impossible. I want my descendants to be emperors for generations, but which great emperor can really achieve it?
So, children and grandchildren have their own blessings, so there is no need to worry too much.

"However, now that you are also professional table tennis players, you still have to aim for Dzogchen in your career." Qin Yuanqing said: "Whenever you do something, you must go all out to achieve it, instead of giving up halfway!"

Table tennis is China's national sport, and it is also a sport in which China has ruled the world since the mid-20s. Whether it is men's or women's table tennis, the criterion for success has never been to become a world champion. The world champion is a specialty of the national table tennis team. , Even the sweeper and cook are world champions. For the national team table tennis players, the real success is to achieve the great consummation of their careers.

"Understood!" The daughter said with a curl of her lips.

Qin Yuanqing smiled. He was very reassured about his children. He believed that they would make the right choice instead of changing their goals day and night. In that case, no matter how good the talent is, there will definitely be nothing in the future. Achievement.

"They are all young table tennis players who have begun to make their mark in the competition. The national team attaches great importance to them and cultivates them as the next generation of table tennis leaders." Jing Tian said here, full of pride.

Qin Yuanqing smiled and did not refute. Qin Yuanqing is not surprised that the two little guys can be regarded as the next generation of national table tennis leaders.First of all, the two of them have very good physical fitness. They have been practicing Taijiquan with Qin Yuanqing since they were six years old. Their physical fitness is definitely among the best among their peers, and they are both very talented. In the early stage, they had the big devil Zhang Yining as their coach. , and laid a solid foundation, even now, he often accepts Zhang Yining's guidance.Secondly, with Qin Yuanqing behind him, even if Qin Yuanqing didn't say a word or say hello, the national team would take special care of the two little guys.Thirdly, Jing Tian is now the sponsor of the Huaxia Table Tennis Tournament. Whether it is the prize money of the tournament or the endorsement contract, it is much more than before.

Therefore, children who have a background and are willing to work hard are often more successful than ordinary people.

But to be honest, whether the children can really have a perfect career depends mainly on them. After all, there are many talented and hard-working table tennis players. Wang Manyu, who changed his own destiny by playing table tennis, no one can predict whether a very bright star will rise in their careers, dazzling.

Every Dzogchen is the right time, place and people, and it is a combination of hard work, talent and luck.

On the first day of the Lunar New Year, when Chinese people were still sleeping late, on the other side of the ocean, the news of the successful launch of the BFR rocket hit the headlines without any suspense.

The United States has once again demonstrated to the world its ambition and strength in the aerospace field, and various newspapers, TV news, and talk shows have carried out related themes and reports.

As Space X, which played an important role in the BFR rocket launch, its stock price rose out of control.

Shareholders don't care at all. The so-called BFR rocket was actually built by NASA and its experts based on the super-heavy launch vehicle technology of the 'Saturn V'. It just looks a little different in appearance. In fact, the technology is still the 'Saturn V' 'Technology.

It is the life capsule, which was also developed by NASA in the past to support Space X!

Including this BFR launch, it seems that Space X is the main force on the bright side, but NASA is still behind it.

But stockholders don’t care about this at all. They only know that Space X is very powerful. Space X successfully launched the BFR rocket. BFR is the most powerful rocket in the world today and has taken the lead in the aerospace field.They only know that Space X's life capsule is the most advanced life capsule in the world. They don't know the truth, but that's what Space X and experts claim.

Shareholders frantically used their money to buy Space X shares, pushing up Space X's stock price.

So much so that even Wall Street is envious of Space X, because this BFR rocket launch will bring billions or even tens of billions of dollars in market value growth to Space X.

"We have the BFR rocket, which is a super-heavy launch vehicle, specially developed for the lunar landing spacecraft. Now we can transport the life module to the moon, and we also have the ability to send astronauts to the moon! We in the United States are still in the aerospace field. leader of!"

"The last time was just an accident. As we all know, space activities are extremely risky activities, and failures are normal! The last launch was just an accident, and now it represents our progress in the field of spaceflight. strength!"

"Look, we have successfully launched so many probes and satellites to Mars. Mars is much farther away from the earth than the moon is from the earth. We can detect and study Mars, and we can even go to Mars. How could it be impossible to land a man on the moon?"

"Space X is just a private aerospace company with such powerful technology. NASA, as the world's number one space agency, must have more advanced technology! We will be able to achieve manned landing on the moon!"

"."

Although the life capsule and the lunar probe are still flying around the earth in geosynchronous orbit, and have not yet entered the earth-moon migration orbit, this is undoubtedly a shot in the arm and a sedative for the American aerospace field, so that the American people are concerned about their own The aerospace field is full of confidence again.

This is the field of aerospace, which represents the high-tech of human beings, the crystallization of a country's industry and technology, and the embodiment of a country's comprehensive national strength.

Each of its milestones is inspiring and able to unite the hearts of the people and inspire their pride and self-confidence in the country.

This, even in the United States is no exception!

　It's not easy to maintain full attendance this month!

　　I wish my friends continue to swim in the sea of ​​books and browse the web in the new year, and keep getting stronger!
　　I wish myself a new year in online writing to a higher level, and set off on the road of great gods!
