Rebirth of science and technology academic master

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 the Spring Festival Gala program team will be relieved at this time, otherwise the ratings will definitely be miserable.

"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.

"The American BFR rocket now carries a small life capsule and a detector. Currently, the successful launch of the rocket refers to reaching the Earth orbit. The success of the entire project also requires continuous orbit changes from the Earth orbit. In the Earth-Moon Migration Orbit, brake and decelerate from the second half of the Earth-Moon Migration Orbit until it is captured by the moon's gravity and fly around the Moon!" Qin Yuanqing popularized common sense about the movement between the Earth and the Moon to his two children: "Flying around the Moon is not considered as orbiting. To succeed, we still need to land on the moon. Although the moon's gravity is far less than that of the earth, this is also very critical. After all, the moon is a celestial body, and its gravity cannot be underestimated. This involves a lot of technology, and any link can go wrong. , will cause the probe to crash into the moon, and the entire launch mission will fall short."

"Then there is 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 play any role." Qin Yuanqing said: "At this point, it can only be considered a success. Half of it still requires the probe to leave the moon and return to the earth!"

Seeing that the two children were confused, Qin Yuanqing directly asked the artificial intelligence to open the simulation video of 'Manned Moon Landing', and then speeded up the video.

No matter what, it can't compare to video dynamic simulation.

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

"This step is to accelerate the orbit. Only by accelerating to a certain speed can the spacecraft break free from the constraints 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 migration orbit chosen by the Chang'e spacecraft is the shortest among all current aircraft, less than a day."

"The speed of the aircraft in the Earth-Moon migration orbit 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 into the universe." Qin Yuanqing pointed out. The video is decelerating and braking in reverse: "So you need to brake. Braking uses the reverse engine to provide reaction force to make the spacecraft decelerate. The spacecraft continues to decelerate until it reaches the speed required for the set orbit, and then Fly around the moon along the set trajectory!”

"."

Qin Yuanqing was very patient with his children's education, allowing them to see the entire spacecraft simulation of the manned moon landing, and also gave them guidance.

This is only Qin Yuanqing's condition. If children from ordinary families don't even have videos, even if there are videos, their parents won't understand the reason.

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

"You choose your own path, but you must know that astronauts need to have a very high knowledge reserve and undergo rigorous training. If you want to be an astronaut, you have to work hard." Qin Yuanqing said with a smile.

The astronauts at this time are definitely the elite of the elite. Each astronaut is trained by the country with huge investment of resources, and the astronauts are extremely outstanding in terms of knowledge reserve and physical fitness.

So much so that some people believe that astronauts are much more valuable than their own weight in gold and are mankind's well-deserved wealth!

Qin Yuanqing would naturally not object to the two children wanting to become astronauts in the future. He felt that it was good for the children to have their own hobbies and goals.

You can't be rich for more than three generations!

Children and grandchildren will have their own blessings!

These are all summed up by China for a long time. Qin Yuanqing thinks it makes sense. Even he does not think that his descendants can be rich and noble for generations. Qin Yuanqing thinks that is impossible. Even the ancient emperors of China think about it one by one. He wants his descendants to be emperors for generations to come, but which great emperor can really achieve that?

Therefore, children and grandchildren will have their own blessings, so there is no need to worry too much.

"However, now that you are also professional table tennis players, you should still aim for perfection in your career." Qin Yuanqing said: "In whatever you do, 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 that China has dominated the world since the mid-1990s. Whether it is men's table tennis or women's table tennis, the criterion for success has never been to become a world champion. World championships are a specialty of the national table tennis team. , even sweepers and chefs are world champions. For the national team table tennis players, real success is to achieve a great career completion.

"I know!" the daughter curled her lips and said.

Qin Yuanqing smiled. He was still very relieved about his children. He believed that they would make the right choices instead of changing their goals day by day. In that case, no matter how talented they are, they would definitely not have any problems in the future. Achievement.

"They are all young table tennis players who are now starting to make their mark in competitions. The national team attaches great importance to them and trains them as the next generation of table tennis leaders." Jingtian said this with pride.

Qin Yuanqing smiled and did not refute. Qin Yuanqing was not surprised that the two little guys could be regarded as the leaders of the next generation of national table tennis. First of all, the physical fitness of the two is very good. They have been practicing Tai Chi with Qin Yuanqing since they were more than 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. , laid a solid foundation, and even now, I often accept 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, Jingtian is now the sponsor of Chinese table tennis events. Whether it is tournament prize money or endorsement contracts, they are 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 children can really have a perfect career depends mainly on them. After all, there are many table tennis players who are talented and willing to work hard. In the past, there were 'Tibetan Mastiffs' who dared to work hard, and later there are For Wang Manyu, who changed his own destiny by playing table tennis, no one can predict whether a very bright star will rise in their career.

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

On the first day of the new year, when people in China were still sleeping in, on the other side of the ocean, the news of the successful launch of the BFR rocket made the headlines without any suspense.

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

Space X, which played an important role in the BFR rocket launch, has seen its stock price rise uncontrollably.

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

It’s the life capsule, which NASA used to support Space X to build!

Including this BFR launch, it seems that Space X is the main force, but in fact it is still NASA behind it.

But stock investors don't care about this at all. They only know that Space X is very awesome. Space They only know that Space

Investors frantically spent their money buying Space X shares, pushing up Space X's stock price.

Even Wall Street is jealous of Space X, because this BFR rocket launch will bring Space X billions or even tens of billions of dollars in market value growth.

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

"The last launch was just an accident. As we all know, aerospace activities are extremely risky activities, and failure is normal! The last launch was just an accident. Sleeping now represents our progress in the aerospace field. strength!"

"Look, we have successfully launched so many probes and satellites to Mars. Mars is much further away from the earth than the moon is from the earth. We can all detect and study Mars, and even land on Mars. How can we not be able to manned the moon?"

"Space

"."

Although the life module 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 calming drug for the American aerospace field, allowing the American people to be more concerned about their own The aerospace field is full of confidence again.

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

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

This is true even in the United States!

It’s not easy to maintain perfect attendance this month!

I wish my friends to continue to swim in the sea of ​​books, read online articles and become stronger in the new year!

I wish you to take your online writing to a higher level in the new year and set out on the road to becoming a great person!
