Finally, after a long high-speed flight, the 'Chang'e 2' spacecraft finally arrived at the predetermined braking point. The reverse force of the plasma engine was seen, providing a reaction force to the 'Chang'e 2' spacecraft, causing the 'Chang'e 2' spacecraft to stop.

The spacecraft began to slow down.

The mass of the moon is much smaller than that of the earth, so the first cosmic velocity of the moon is much smaller than the first cosmic velocity of the earth. In order for the aircraft to be captured by the moon, it must reach the first cosmic velocity of the moon before it can be captured by the moon.

, into lunar orbit.

Otherwise, if the speed is too high, the aircraft will be thrown off the moon and never enter the lunar orbit. This can be seen from the circular motion.

As the plasma engine continues to provide reverse force, the 'Chang'e 2' spacecraft continues to decelerate, and the Earth-Moon Monitoring System continuously monitors the speed and trajectory of the 'Chang'e 2' spacecraft, thereby transmitting it back to the earth for ground command.

center.

Braking is related to the success or failure of the Chang'e 2 spacecraft, and it can be said to be a key node.

The ground command center is keeping an eye on the Chang'e 2 spacecraft and is in constant contact with the astronauts.

"The spacecraft is in normal condition and is currently undergoing deceleration. It is expected that the speed will reduce to the moon's second cosmic speed of 2.38km/s in 1.5 hours and enter the lunar orbit. The spacecraft will complete the orbit change and reduce to the moon's first cosmic speed of 1.68 after 2 hours.

km/s, make a circular motion around the moon!" The commander of the 'Chang'e 2' spacecraft reported.

At this time, the speed of the 'Chang'e 2' spacecraft reached an astonishing 14km/s, and then the speed dropped from 14km/s to 2.38km/s within 1.5 hours. If it had not dropped to this range, 'Chang'e 2' would have

The spacecraft will pass by the moon and will not be captured by the moon. It will have to readjust its direction and angle to correct its orbit and direction.

And this is undoubtedly very time consuming.

Therefore, manned lunar landing is not easy. Every link requires precise control of the spacecraft. Any error in any link may cause the entire manned lunar landing project to fall short.

"Three minutes later, the 'Chang'e 2' spacecraft switched from the Earth-Moon Migration Orbit to the Moon Orbit!" Liu Yang reported the speed of the spacecraft against the time.

As the 'Chang'e 2' spacecraft reached a predetermined speed at a predetermined position, it was immediately captured by the moon's gravity, thus entering the lunar orbit. Although it was not a circular motion, it was in the lunar orbit, and the next step was to continuously decelerate.

Constantly changing course.

"Beijing, Beijing, the Chang'e 2 spacecraft is currently in synchronous orbit of the moon!" Commander Liu Yang reported the situation to the Earth Ground Command Center.

"The lunar module will separate in 15 minutes!" the ground command center issued an instruction.

"receive!"

At the same time, in the command module of the 'Chang'e 2' spacecraft, Liu Yang ordered the other five astronauts to enter the lunar module. As commander, she will stay in the command module. This is a tradition left over from the 'Chang'e' spacecraft.

But this time, the "Chang'e 2" spacecraft is different. The lunar module will travel to and from space and the lunar surface many times, carrying out multiple missions. Therefore, as commander, Liu Yang will also have the opportunity to set foot on the lunar surface again.

"Lunar module separates!" When the time comes, the lunar module separates from the command module according to the set procedure. Next, the lunar module will start to land on the lunar surface. There is no doubt that compared with the spacecraft landing on the earth, it takes

After experiencing the atmosphere and terrifying gravity, it is much easier for the lunar module to land on the lunar surface. The real difficulty lies in whether the lunar module can land accurately and steadily to the set landing point.

This time the lunar module landed on the lunar surface without any accidents. It landed steadily at the set landing point. It was only 500 meters away from the life module and the Moon Rabbit rover that were launched last time. It can be said to be extraordinary.

Accurate.

At this time, the ground command center burst into warm applause when they saw the scene at the landing point. They knew that the Chang'e 2 spacecraft had been successful once they got here. Even if there was any accident, the astronauts could live on their own for more than one day.

month time.

Within a month, SA launched a manned spacecraft again to rescue.

As astronauts stepped out of the lunar module one by one, they continued to celebrate in various ways, and once again set off the 'lunar landing style'. At this moment, countless people couldn't help but imitate it, and it also made people watch.

The distinctive personalities of this group of astronauts born around 2000.

Wang Yaping was the last astronaut to step out of the lunar module. This was her second time on the lunar surface, and she became the first female astronaut in the world to step on the lunar surface twice.

At this time, as the astronauts walked out of the lunar module, the ground command center on the earth burst into warm applause, celebrating the second time that China had successfully sent astronauts to the lunar surface, which was a great pioneering feat.

Compared with the Apollo project, the 'Chang'e' spacecraft and the 'Chang'e 2' spacecraft both carried six astronauts. The number at a single time far exceeded the Apollo project. The entire Apollo project had six manned lunar landings, that is,

It sent 12 astronauts to the lunar surface, and now China's two manned lunar landings have tied this record.

Even if the Apollo program is true, China's manned moon landing is only a quantitative difference from the Apollo program, but it is far superior in terms of quality.

The astronauts began to test drive the Lunar Rabbit vehicles. These Lunar Rabbit vehicles require authorization from the ground command center, otherwise they will not be started at all.

Then, people on earth who were watching the live broadcast saw astronauts driving the Moon Rabbit Car on the surface of the moon. Although the Moon Rabbit Car was not fast and was far inferior to cars on Earth, there was no doubt that it was on the moon.

An important tool for operations on the moon.

An hour later, the live broadcast entered the commentary and advertising time, and the astronauts began to activate the life capsule, build and install various equipment, which they had practiced many times at the Earth Training Center.

Wang Yaping, as the deputy commander of the Chang'e 2 spacecraft, opened the door of the life capsule.

Five hours later, Wang Yaping will conduct an online lunar class here, telling everyone about the manned lunar landing project and the situation of the moon. This will help people understand the moon more intuitively and clearly, and understand that the moon is a great treasure.

It can provide a large amount of resources for mankind and is the bridgehead for mankind to step out of the earth, the cradle of life, and enter the universe.

As an astronaut, in a sense, he is at the forefront of the times. Wang Yaping even came into contact with some confidential things and knew that developing the moon would be the general trend.

For example, what they will install next is helium-3 mining equipment. The mining equipment is modular and only needs to be set up, and it will naturally mine automatically. Then the helium-3 mined will be collected and brought back to the earth before they leave the moon, including 1

The same is true at the No. 1 scientific research station.

"Dear students, I am currently giving a lecture to you at my country's No. 2 Scientific Research Station..." When the time came, Wang Yaping gave a lecture on the moon on time.

As the first astronaut to give lectures in space, many students engaged in aerospace engineering or became astronauts because of Wang Yaping's special course.

"It's so awesome. Just a few hours after landing on the moon, a scientific research station was successfully established. In this way, our country will have two lunar scientific research stations and take the lead in lunar exploration."

"Looking inside the scientific research station, there is everything you need. I even saw a lot of tomatoes and white radishes... Sure enough, we are going to open up fertile fields on the moon and plant food and vegetables in the future.

, specifically for the needs of the earth.”

"It turns out that the moon has so many resources, even more rare earth reserves than the earth. A lunar crater is an impact of an extraterrestrial meteorite. Each lunar crater is a vein of minerals that can be mined and refined for gold, platinum, etc...

.. Dear fellow Taoists, I want to start a crowdfunding campaign and go to the moon to mine, it will definitely be very profitable!”

"I want to go to the moon and build a moon palace so that tourists can go to the moon palace and look at the beautiful earth... That is the real heaven and earth!"

"It is said that Fairy Chang'e, Fairy Chang'e, is the most beautiful woman in the fairy world. It's a pity that Fairy Chang'e has not been found even after landing on the moon and looking around every corner of the moon. Otherwise, she must have been very good at bringing her back to Earth."

"..."

Compared with the various positive and negative comments from China, far away in the NASA conference room on the other side of the Pacific, hundreds of people were in the conference room at this time, with heavy faces. No one thought that China would be the second manned moon landing.

The 'Chang'e 2' spacecraft went so smoothly, with no trouble at all.

Look at the Chinese people, they built a scientific research station in a few hours. With this scientific research station, Chinese astronauts can stay on the moon for a longer time.

With a scientific research station, China's exploration of the moon will be in front of everyone!

No one even knows whether missiles can be launched from that scientific research station? In that case, even the most advanced missile defense systems in the world would not be able to defend it.

"Damn it, they are really pressing forward step by step, without giving us any time to breathe!" A middle-aged man cursed in a low voice.

China has succeeded in its second manned lunar landing. Even though NASA has successfully completed a manned lunar landing before, it still feels a lot of pressure.

After all, the image NASA has always established to the outside world is that of a leader in the world's aerospace field, leading the development of the world's aerospace, and even rewriting the Soviet Union's aerospace contribution in the 20th century. But now, the outlined aerospace supremacy has collapsed.

.

However, aerospace technology is real and cannot be faked at all. It relies on hard power! As for the United States, the last aerospace accident has not yet recovered, and the problem has not yet been discovered.

Although NASA has been claiming that NASA will launch a manned mission to Mars in 2030, but by then the blond old man has left with a slap on his ass, then the manned mission to Mars may be delayed again and again.

At least now, NASA doesn’t really hype the topic of manned landing on Mars. Those who speculate on colonizing Mars are private space companies such as Space

, as for whether it is really manned to land on Mars, this is not very important to the super rich at all.
