I'm an almighty star

Chapter 1509 Playing with the phone while riding the rocket
"Ignition, lift off."

"Fly up, fly up."

"Mo Bai flew up."

The thick flames released from the bottom of the rocket pushed the rocket into the sky continuously.At the same time, various instruments in the control room of the Huaguo Space Center are tracking the Long March 100 rocket in real time in all directions.

"The speed of the rocket was not particularly fast when it first launched, and its speed was continuously accelerated step by step."

"Let's look at the camera, and in the camera we can see that the rocket has become smaller and smaller, almost like a shooting star."

"Now we can barely see a small dot, and now we can't even see the small dot."

"Of course, our signal is still very good. It can be seen that everything is normal in the entire rocket launch."

Facing the camera, the host of CCTV continued to explain the entire launch.

Although the rocket lifted off, the whole process of landing on the moon has just begun.

Without a formal landing on the moon, it is not yet possible to say that the entire moon landing program has been successful.

With a distance of more than 30 kilometers between the earth and the moon, the Long March 100 rocket still has a series of key points to overcome.

"Professor Liu, as far as I know, it takes 8 days to land on the moon this time. Why did it take so long?"

"Theoretically speaking, if it is launched towards the moon at a straight-line distance, he does not need 8 days, one day is enough. However, our Long March 100 rocket does not go straight to the moon, but is divided into several parts. Steps. The first is to enter the 16-hour orbit. In this orbit, our Long March 100 rocket will circle the earth once, the ground will issue an acceleration command, and then enter the 24-hour orbit again. One day later, our Long March 100 rocket will accelerate again , into the 48-hour orbit... Two days later, our Long March 100 rocket will officially enter the lunar orbit, and then officially land on the moon on the eighth day."

Professor Liu Yuan explained patiently: "Maybe many friends have asked why we have to divide so many steps instead of going straight to the moon. There are many reasons for this. First, our Long March 100 rocket landing on the moon is not just a completion For the plan to land on the moon, after the rocket reaches a certain orbit, he has to collect various information.”

"This is understandable. The last time space was not easy, it can't just go to the moon."

"Second, and a relatively important reason. The reason why it is divided into several steps is to save fuel."

"Professor Liu, we don't understand this. Landing on the moon in a few days can save fuel. Didn't you save fuel by running there in one go?"

"Haha, most people probably think so."

Liu Yuan smiled and said: "In fact, it is not. Take the acceleration of our rocket as an example. If we want to accelerate the rocket, what should we do?"

"Step on the gas pedal."

"Well, there is no accelerator setting on the rocket. However, it is similar to stepping on the accelerator, that is, it consumes more fuel. Only by releasing more fuel can our speed be increased. However, according to the law of gravity, everything has Gravity, similarly, there is gravity between planets. After our Long March 100 rises to a certain height, it will use the gravitational field between the earth and the moon to accelerate the rocket, which we call gravitational acceleration."

"Gravity acceleration, I didn't expect that there is such a word in physics."

"Yes, it is precisely because of this gravitational acceleration. The Long March 100 rocket does not need to burn too much fuel. He only needs to use gravitational acceleration to push our Long March 100 to the moon. So, This also achieves the purpose of saving fuel."

"I see."

The host nodded.

A group of fans and spectators also benefited a lot from listening.

I didn't expect that there would be so much knowledge about space travel, it really is a lot of knowledge.

"We set our sights on the lunar module."

"At this time, Mo Bai was sitting in the lunar module very calmly."

At this time, the camera showed Mo Bai sitting quietly in the lunar module.

"Professor Liu Yuan, you said earlier that the astronauts will receive a very strong boost when the rocket takes off."

"Yes, it is difficult for ordinary people to adapt to this powerful boost. If an ordinary person is put on the lunar module, he may have been pushed unconscious by now."

"Mo Bai's current situation is very good. It can be seen that Mo Bai is relatively relaxed now."

"This also proves that Mo Bai's physique is indeed not comparable to that of ordinary people. Of course, this is also inseparable from the training before landing on the moon."

"By the way, Professor Liu, can our astronauts take a shower in space?"

"of course."

"Isn't there no gravity in space, how do you take a shower?"

"This one is also simple. Our researchers made a bath bag specially for astronauts. The inside of the bath bag is pressurized at 0.8 atmospheres, and an exhaust fan is placed under it. In this way, astronauts can take a bath like an earth shower. "

"Wow, it's so convenient, our scientific researchers are really amazing."

"It is convenient to say it is convenient, but it is not convenient to say it is inconvenient. After all, water resources are precious in space, and there is no gravity in space. Astronauts may only take a bath for 15 minutes, but it takes a long time to take a bath and process and recycle the water after bathing." At least 45 minutes."

"This is indeed incomparable with the earth."

The entire moon landing program lasted 8 days.

Although the ignition and the initial lift-off have just started, everyone is extremely excited.

However, when the rocket flew for more than half an hour, many people yawned and prepared to go to bed.

"Brothers, I can't stand it anymore, go to bed first."

"I'm going to sleep too, and I'll watch it tomorrow."

"Now it's impossible to fly to the moon. Everyone should go to bed early and watch the live broadcast when we land on the moon."

This is true.

For 8 days, no matter how awesome you are, you can't keep staring at it.

Besides, let’s not talk about them, even if it’s CCTV and they do the live broadcast, the first stage is only about 1 hour.

The highlight is not now, but Mo Bai actually set foot on the moon on the 8th day.

"Professor Liu, will the astronauts feel bored during the 8-day space travel?"

"How do you say this? If you say no, it is absolutely impossible. It would be fine if several people go together, and everyone can chat, but this time the moon landing is a person, and chatting is impossible."

"Then what should we do? Could it be that Mo Bai just sat there blankly all the time?"

"It's not so boring. If Mo Bai wants, he can choose to listen to music or read a book. If he is tired, he can sleep."

"Well, Mo Bai's sleep will not be broadcast live."

"Hehe, that's not the case. Astronauts have their own private space. Except for normal work arrangements, Mo Bai's other private spaces are not monitored."

It's been almost an hour since the live broadcast, and the chat is over.

We can't talk about things we shouldn't talk about for the time being.

At this time, the host chatted with Professor Liu Yuan casually.

Many fans also chose to go offline and fell asleep.

However, at this moment, Mo Bai was probably bored.

After flying for an hour, Mo Bai took out his mobile phone.

"cell phone?"

"Oh my God……"

"Professor Liu Yuan, Mo Bai actually brought his mobile phone."

The host exclaimed.
