Deep Space Planet Leader

Li Zhendong was surprised, but looking at Zhang Yuan's face, it shouldn't be talking nonsense.

Furthermore, working on a project with a professor in the university sounds much more reliable than his "game".

Inexplicably, Li Zhendong kind of wants to take refuge in each other.

However, he can't shame at all!

He said again: "What about the thesis? Have you considered it? I plan to take a postgraduate entrance examination on spaceship. Undergraduates like ours may be from the bottom of the society, so miserable."

"...I should pass the grade point and pass the postgraduate exam, but I don't have a particularly good paper. Where did the undergraduates get a good paper... so annoying! My dad doesn't bother to guide me!"

Zhang Yuan scratched his head, not knowing what to say.

If his paper is successfully published in "Modern Science", as long as the written test results are decent, there will be a teacher who will ask him to be generally speaking.

A regional journal of the level of "Modern Science", an average university professor, it is not bad to publish such an article for a lifetime.

"Do you have a good idea of ​​what major to study for graduate students?" Zhang Yuan is a bit sorry, "I have already submitted a paper to Modern Science. If it can be published, I should be able to add a bit of interview points."

"Huh, "Modern Science", you?" Li Zhendong was taken aback again, but he couldn't react for a while.

Just as the two were chatting, there was a burst of joyous screams from the girl next door.

"The sun!"

"What a beautiful sun!"

It is the sun rising from the horizon.

When you witness the sun at an altitude of several hundred kilometers, you will find that it becomes unusually bright.

The position of the sun became very accurate, without any halo, exuding a dazzling and overbearing white light.

If there is no radiation shielding material, this solar radiation can easily sunburn people, and even damage the DNA of human cells, causing permanent damage.

Because of this, human astronauts in the old age were not allowed to go to heaven before giving birth. But now with the generation of improvements in radiation protection materials, there is no such requirement.

There are several dark clouds underneath that are bursting with lightning, flashing like dianthus flowers in full bloom. Sometimes you can see lightning from different cloud layers in five or six places, illuminating the entire cloud layer.

These scenery are not visible on the ground.

The girls screamed excitedly: "These clouds are so small, they are not the same as those seen on the plane!"

"It must be different. The plane is only a few kilometers away. High..."

"It's kind of like a cotton ball exploding!"

"If we really fall from this height, we will become a fireball, just like a meteor. . It’s burned to death, not to death!” A boy threatened very badly, “Can you imagine the scene turned into coke?”

"Ah!"

chirp chirp twitter twitter's yelling, coupled with all kinds of panic screams, made Zhang Yuan couldn't help laughing.

Perhaps, he was in the same mood when he first took the space elevator.

In the next few hours, as the altitude increased sharply, the entire Eastern Hemisphere could be seen.

The pure white snow of the Himalayas is vast and desolate; the reddish-brown vortex on the Cavill Desert carries a kind of primordial mysteriousness; the Spiritual God of the Southeast Asian Islands shines like an emerald... …

Exciting, really exciting!

Overlooking the entire Earth, there is a sense of boldness that "the world is in my hands".

The vast Earth really floats quietly in the universe just like in the photo.

Earth is really round, and naked eye is visible.

The current height is 600 kilometers.

According to a scientific survey, at this height, more than 90% of people will have an unparalleled sense of worship for natural science, the motherland and the space elevator.

Earth is very big, too big!

Even the "octagon", the largest building for humans, is just as insignificant as an ant.

But a small human being, from this angle, can easily see every trace of Earth's outline!

This kind of strong contrast has produced another kind of visual impact. Looking down like a Spiritual God, everyone has a strange pride, the entire world has been stepped under their feet.

Humanity has actually developed to this level. The Tower of Babylon that leads to the boundless sky, the incomparably powerful force against nature, is really... incredible!

Compared to space travel, what is the world travel?

Hearing the exclamation of the passengers, Zhang Yuan sighed: "You are young, so good."

Li Zhendong nodded agrees: "too-young, too-native."

The girls next door are still on chirp chirp twitter twitter, very excited, they are looking for famous buildings and natural landscapes on the surface.

"There should be Donghua City..."

"There——Imperial Capital?"

"That mountain is Mount Everest, right?"

"No, it should be Nanga Bawa Peak."

"That, it should be Wanwan Island..."

Unfortunately, the Seventh World One of the miracles-the Great Wall, there is no way to distinguish it with naked eye. It is a pity that everyone feels it strange.

I used Warwick’s P888 mobile phone to shoot the Great Wall.

There are also several broad asphalt roads, because they are in sharp contrast with the surrounding environment, and can be vaguely seen, just like strands of hair.

The girls were discussing excitedly, taking pictures and cheering.

……

After a few hours, the tourists finally lost interest and became quiet again. There is no network here, and there is no way to post to Moments. I was in a state of interest but I couldn't share it. I was panicked.

"That... handsome guy?"

Zhang Yuan and Li Zhendong looked at each other.

What about me?

It's me!

"...Handsome guy, are you that one, that Zhang Yuan? The one who donated money! You turned out to be an astronaut!" The other party looked very excited.

Zhang Yuan touched his head, is he already so famous?

The girl opposite took a look at him and said excitedly: "...At that time, I happened to be watching the live broadcast. I really didn't expect you to be an astronaut. Don't you want to stay in Earth? Enter the entertainment industry?"

"When did I say that I would enter the entertainment industry? I never planned to..." Zhang Yuan coughed and replied: "I will follow spaceship and leave the solar system."

"I knew! The son of a great scientist, how could he do such boring tricks. Haha, I am not saying that being a star is not good, but the social value created is definitely not as good as that of a scientist. I Can you clarify this fact by posting to Moments?"

"Post it, it’s okay."

The girl clicked on her phone and found that there was no internet, so she could only give up.

She seemed to see that Zhang Yuan was a little embarrassed, and again asked a very well-answered question: "Well, I have a question to ask you. Outside the window, those ring-shaped ones will light up. What’s the device?"

Zhang Yuan replied: "That is an ion propulsion device. When we reach the Earth synchronous orbit, the linear velocity is about 3.1 kilometers per second, and the lateral linear velocity of this part is determined by The electric propulsion engine is provided to reduce the lateral deformation of the elevator track."

"Oh..." The girl seemed to understand.

Zhang Yuan smiled.

Actually, there are more ion engines on the "Tenglong" space city to maintain the orbital height of the space city.

Think about it. When a person pulls a hydrogen balloon to obtain an upward pulling force, the hydrogen balloon will receive a reaction force, that is, a downward pulling force.

For the same reason, when the freight elevator climbs up the cable track, it will lower the height of the space city. Therefore, it is necessary to rely on jet working fluid to push the space station to a synchronous orbit again to maintain dynamic balance.

Even if the space elevator has been built, it is still necessary to use working fluid to maintain balance. What a tragic thing.

But this is already the best way to climb the gravitational well. Who said that the space elevator is not a rigid body?

Human technology, in fact, is far from being as superb as imagined.
