Chapter 190 Lagrangian Point

When the third child was frightening the children, the eldest was holding a small red flag in his hand.

“Ahem! Good evening, grandpas, this time we are responsible for picking up you all. Please keep order after boarding the boat for a while, line up and follow my little red flag. If the flag doesn’t fall, you are not allowed to run around. If I lose one, I will be deducted from my salary! Thank you for your cooperation…”

This familiar tour guide’s opening remarks made everyone twitch their mouths. Look at the people present. Except for the seven or eight hands and feet, it is convenient to be able to move on their own. The rest is either in a wheelchair or lying on a stretcher. You run one and let me see!

“Hey! Lao Liang, these two people who came to pick us up look unreliable…what SOS organization is really okay?” An old man with gray hair and wrinkles sat next to him. The rosacea old man in the wheelchair said.

“Lao Yu has confirmed it, there should be no problem! Besides, just our old bones, what can others use for us? Just the technology in our minds, maybe people really look down on it.”

Before they set off, these scientists were informed in advance of some information from Captain Ghost and the SOS organization. No one could not say a word about the black technology of Captain Ghost. The style of painting is so different from this era!

“Well, after seeing the old one in a while, it will be clear whether this matter is true or not…”

“Oh! Coming!” At this moment, the boss suddenly turned his head and said.

“Wow~” Under the moonlight, like a giant silver whale slowly emerging from the water, everyone slowly opened their eyes…

…

Secret base of the earth.

“Lagrangian?!” Nie Yun looked at the excited Yu Lao in front of him and wondered.

Information about the Lagrange point immediately appeared in his mind.

Lagrangian point (Lagrangian point) refers to some special positions in space, at which the gravitational and centrifugal forces of two celestial bodies are balanced at this point, so that the third object remains relatively stationary with the first two objects.

For example, if a satellite is placed on the Lagrangian point of the solar-terrestrial system, then the satellite, the sun and the earth can remain relatively stationary, and the observation activities of the two can be carried out stably.

This characteristic of Lagrange point makes it of considerable strategic value in the space age!

Because it does not need to consume fuel or consume very little fuel to maintain orbit stability, and in the space age, the operating cost is lower, and it has the best conditions to become a transportation hub!

This is like Shanghai’s natural strategic location, which is destined to become an important transportation hub in global trade!

“I didn’t consider this before. Indeed, this feature is really suitable for placing monitors!”

Although Nie Yun has a large amount of astronomical data in his mind, he is not a professional astronomer after all, and there are still blind spots in his thinking!

In his mind, he immediately began to quickly analyze the possibility of the existence of the alien probe at the Lagrangian point…

There are a total of 5 Lagrangian points around a large celestial body such as Planet or Star. Taking the solar-earth system as an example, these 5 Lagrangian points are L1~L5.

Among them, L1~L3 are on the line between the two celestial bodies.

The first Lagrangian point L1 is located between the earth and the sun, about one million miles away from the earth.

Observing the sun on L1 can be free from gravitational interference. This point has now been occupied by the human “Solar and Heliospheric Probe” (SOHO) and “Deep Air Elephant Satellite”.

L2 is also located at a distance of about 1 million miles from the earth, but unlike L1, it is not between the sun and the earth, but on the extended line of the sun and earth.

The spacecraft in this position can clearly observe Mars and the entire deep space because the sun, the earth, and the moon are all behind it.

At present, NASA’s Wilkinson Microwave Anisotropy Probe (WMAP) is measuring the residual thermal radiation after the Universe Big Bang at point L2.

These two Lagrangian points have been occupied by the above-mentioned probes from Europa and NASA, and these probes are very close to the earth. Not long ago, they have been changed to Nie by the way in the “Solar System Reconnaissance Network” project. The detector is unlikely to be able to engage in espionage under Nie Yun’s nose, and it can basically be ruled out.

The third Lagrangian point L3 is located on the extended line of the Earth and the Sun opposite to the direction of the Earth. It is separated from the Earth by the Sun. If the probe is at L3, the difficulty of penetrating the Star to detect the Earth may have been a breakthrough. Skyrim can basically be eliminated.

So, there are only two points left, L4 and L5!

They are located on both sides of the earth and are the two intersection points of the vertical bisector of the sun-earth line and the earth’s orbit.

These two points are one of Nie Yun’s current detection blind spots!

“Well! Considering the kinematics of celestial bodies, this is the best possible position for the detector! I prefer the two points L4 and L5!” Yu Lao said similar judgments to Nie Yun.

“Um… But considering that the other party’s technology may far exceed the earth, the possibility of other locations is not ruled out…

But if you want to be very concealed, this is probably a passive detector. For the fixed target of the earth, the amount of passive detection is actually enough!

It is also very possible to do appearance camouflage, or even optical stealth processing!

In addition, since it cannot be discovered by the existing detection technology on the earth, the communication method of the other party should not be traditional radio technology, perhaps it is extremely difficult to detect, laser communication with excellent confidentiality, or more advanced quantum communication, or even beyond The means of communication I know…”

While talking, Mr. Yu observed Nie Yun’s expression.

He used the “other party” many times in his words just now, but Nie Yun didn’t say anything about it. He apparently acquiesced in the existence of the “other party”, and he couldn’t help but feel more certain about his previous judgment.

Sure enough, I didn’t find myself the location of the detector! Is the boss’s opponent… Suddenly so excited…

How could Nie Yun fail to discover Yu Lao’s careful thoughts, but sooner or later, he must let them know, not telling them directly because even he himself knows very little about this group of B star people, even whether the detector exists or not. Questions.

If you have an oolong yourself at that time, you will have no face as a boss, okay!

Could it be said: “Oh, I made a mistake, it turned out that I scared myself, so embarrassing…”

If you say that, the tall SOS organization will force the grid to fall to the end, okay!

“Well! You did a good job. I will send detectors to inspect these two locations. Regardless of the results, as a reward, all the detection data of the Sea Wolf will be available to you!” Nie Yun smiled.

Yu Lao got excited in an instant, this kind of space observation data is the most precious thing for astrophysicists like him!

But he will soon discover that Seawolf’s detection data is not only in the orbit of the earth…

“By the way, your colleagues are almost here, as their leaders and old acquaintances, go and say hello to them before then, and they can feel relieved.

In addition, I will arrange gene reflux surgery as soon as possible, and you are also ready to prepare. “Nie Yun gave Yu Lao a meaningful look.

“Hehe! Boss, don’t worry, leave it to me!” Yu Lao smiled…
