Black technology: starting with space jump machine

A large astronomical observatory in the United States.

As an astronomical observatory built in recent years for the so-called new round of space hegemony, in addition to defrauding a huge amount of capital investment, this facility has the most sensitive radio telescope array in North America, and its accuracy can even track meteorite fragments and space debris with a diameter of only half a meter - as long as it is within the Earth-Moon system.

It can only be said that the United States still has some things left, and in addition to China's intention to promote some marginal technologies in recent years, the United States built this observatory.

However, this little thing is destined to be far behind by China, which is developing by leaps and bounds.

This astronomical observatory is nominally looking for habitable planets outside the solar system, but in fact most of the observation tasks are concentrated in the Earth-Moon orbit, and its purpose is self-evident.

About a few days ago, China announced its launch schedule to the international community, announcing to the world that it would carry out a staggering collective launch.

The scale of its launch is so large that experts wonder whether China's aerospace industry has left all other countries behind and entered the interstellar era.

In the astronomical observatory, most of the American experts have gray hair. In fact, they are about the same age as the Chinese experts, but China's life extension technology and nanotechnology have made the two sides of the same age look very different.

In fact, if they are willing to apply for Chinese citizenship, like many of their former colleagues, they can also line up to enjoy various high-tech medical treatments.

After all, the Chinese scientific community has never closed the door to absorb elites from various countries in recent years. Nearly half of the scientists who participated in the astronomical conference a few years ago chose to become Chinese citizens.

But every country has some scientists who are still willing to stick to certain principles, such as this old expert who is now gray-haired and holding a cup of coffee in front of the projection screen.

Since China officially announced the launch plan, he and the observation team he led have not taken a day off. They are on call at their work posts almost 24 hours a day, and they dare not relax even for an hour.

"This collective launch will include 166 space shuttles, with a 100% success rate."

"According to the carrying capacity of China's space shuttles, my God! Do they want to build another lunar base at the North Pole of the Moon at one time?"

The reports came one after another, and the expert listened expressionlessly. But for some reason, he actually felt a slight sense of relief in his heart.

Once upon a time, they were the only leaders in deep space exploration on this planet. Now that China has changed its previous mild launch plan and revealed its true aviation level, the experts understand that there has even been a technological gap between them.

Those NASA officials can't even deceive themselves now, right?

Deep space development is the future of all mankind. Isn't it good to join the Federation's agreement honestly?

It has been rumored that China is going to start building a space elevator. Now it seems... there is actually some possibility!

Just as he was thinking about this, his assistant quickly walked in to report.

"The shuttle fleet didn't go to the moon?"

"They headed for the second Lagrange point?"

The professor's eyes widened for a moment. The projection screen made in China showed that the huge shuttle fleet did not go to the moon by using the gravitational slingshot effect of the earth, but went to the second Lagrange point in the sun-earth system.

When Lagrange was studying the restricted three-body problem, he found that there were five special coplanar points of the third body moving around the two celestial bodies. The gravitational force and centrifugal force on the objects at these five points were basically balanced. Later, people called these five points Lagrange points, also known as libration points. In the sun-earth system, the sun, the earth and the probe constitute a restricted three-body problem, and there are five Lagrange points L1, L2, L3, L4, and L5.

By arranging relay satellites at these five points, the satellites can be orbited with less energy consumption, and the relay satellites can exist stably for a long time, thereby reducing the operating costs of the space network.

Looking at such a large-scale launch, it is certainly not as simple as building a satellite?

As time went by, they even connected to the space telescope to synchronously observe what was happening in space.

When the space shuttles were about to reach the second Lagrange point, they opened their cabins and ejected groups of standard blocks.

What surprised the institutions that were always observing the situation here was that the groups of standard blocks slowly approached each other and then merged at the connection!

You know, they look like they are moving slowly, but in fact they still retain a very high speed and kinetic energy. If you are not careful, they will immediately cause a space accident.

They should explode immediately when they collide with each other. How can they be as smooth as seamless connection?

Groups of standard blocks seemed to be assembled by a pair of invisible hands. All the blocks were combined to form a ring that firmly occupied the second Lagrange point!

And this process took only two hours!

In the eyes of Americans, it was like a miracle!

"This is impossible!"

"They are not building a space station, but a space city!! They are using nanorobots to assemble these modules!"

"Oh my God! Their nanotechnology can already be used in cutting-edge medical treatment. I should have known that this technology would be used in aerospace engineering sooner or later!"

The expression on the expert's face was equally shocked.

If the carrying capacity of the space shuttle was not limited, and the cubes transported this time were only these, the expert had no doubt that when he woke up, the first space city in human history would have been completed!

Building a city overnight!

And it was a space city, which sounded like a dream, but it really happened before his eyes!

This is no longer a generation gap, but a gap in the level of civilization!

No matter how much you know shame and then be brave, you are destined to not catch up with the gap...

[Is it too late to apply for naturalization now? ]

The expert once again felt deep regret. If he had chosen to stay after the astronomical conference, he didn't know if he could also enjoy the joy of completing this great project on the other side, instead of just staring at it in amazement now.

"Please submit my resignation letter to NASA for me."

Looking at the space city in front of him, the expert realized that his persistence was no longer meaningful.

God no longer blesses the United States. Next, they need China to bless them, especially from space...

Written on the successful launch of Shenzhou XIV and the postponement of the new generation of American moon rockets.
