Chapter 190 Lagrangian Points
When the third child was scaring the children, the eldest was holding a small red flag in his hand.
"Ahem! Good evening, grandpas. We will pick you up this time. Please maintain order after boarding the ship. Line up and follow my little red flag. If the flag does not fall, you are not allowed to run around. If I lose one, my wages will be deducted! Thank you for your cooperation..."
The familiar opening remarks of the tour guide made everyone’s mouths twitch. Look at the people present, except for seven or eight hands and feet who are more comfortable and able to move on their own.
"Hey! Old Liang, these two people who came to pick us up don't look very reliable... Is this SOS organization really okay?" An old man with gray hair and wrinkled face sat beside him. Said the rosacea-nosed old man in the wheelchair.
"Old Yu has confirmed it, there should be no problem! Besides, with our old bones that are about to sink into the ground, what can people think of us? With the technology in our minds, maybe they really don't like it."
Before setting off, these scientists were informed of some information about Captain Ghost and the SOS organization in advance. No one could help but say a word of convincing about Captain Ghost's black technology. The style of painting is really far from this era!
"Well, after seeing Lao Yu for a while, you will know whether this matter is true or not..."
"Oh! Here we come!" At this moment, the boss suddenly turned his head and said.
"Wow~" Under the moonlight, like a giant silver whale slowly surfacing from the water, everyone slowly opened their eyes wide...
……
Earth's secret base.
"Lagrangian point?!" Nie Yun looked at the excited Yu Lao in front of him and asked in confusion.
Information about Lagrangian points immediately came to his mind.
Lagrangian points refer to certain special positions in space where the gravitational and centrifugal forces of two celestial bodies are balanced at this point, making the third object remain relatively stationary with the first two objects .
For example, if a satellite is placed on the Lagrangian point of the sun-earth system, then the satellite, the sun and the earth can remain relatively stationary, and observation activities can be carried out stably.
This characteristic of Lagrangian point makes it have considerable strategic value in the space age!
Because it does not need to consume fuel or consumes very little fuel to maintain a stable orbit, and in the space age, the operating cost is low, so it has the best conditions to become a transportation hub!
This is like the natural strategic location of Shanghai, destined to become an important transportation hub in global trade!
"I didn't think about this before. Indeed, this feature is really suitable for placing monitors!"
Although Nie Yun has a huge amount of astronomical data in his mind, he is not a professional astronomer after all, and there are still blind spots in his thinking!
He immediately began to analyze the possibility of alien probes existing at Lagrangian points in his mind...
There are a total of 5 Lagrangian points around large celestial bodies such as planets or stars. Taking the Sun-Earth system as an example, these 5 Lagrangian points are L1~L5 respectively.
Among them, L1~L3 are on the connecting line between the two celestial bodies.
The first Lagrangian point, L1, is located between the Earth and the Sun, about 100 million miles from the Earth.
Observing the sun on L1 can be free from gravitational interference.This point has now been occupied by humanity's "Sun and Heliospheric Observatory" (SOHO) and "Deep Space Weather Satellite".
L2 is also located about 100 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 the earth.
The spacecraft in this position can clearly observe Mars and even the entire deep space because the sun, the earth and the moon are all behind it.
NASA's Wilkinson Microwave Anisotropy Probe (WMAP) is currently at point L2 to measure thermal radiation left over from the Big Bang.
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 were renamed Nie in the "Solar System Reconnaissance Network" project, extraterrestrial It is unlikely that the detector can still engage in espionage activities under Nie Yun's nose, which can basically be ruled out.
And the third Lagrangian point L3 is located on the extension 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, then the difficulty of penetrating the stars to detect the earth may have been broken Skyrim can basically be ruled out.
Then, there are only two points L4 and L5 left!
They are respectively located on both sides of the earth, and are the two intersections of the perpendicular bisector of the line connecting the sun and the earth and the earth's orbit.
And these two points are one of Nie Yun's current detection blind spots!
"Well! Considering astrokinematics, this is the best possible position for the detector! I am more inclined to L4 and L5!" Yu Lao expressed a judgment similar to Nie Yun.
"Well... but considering that the other party's technology may be far superior to that of the earth, the possibility of other locations cannot be ruled out...
And if you want to be very concealed, this is likely to be a passive detector. For the fixed target of the earth, the detection amount of passive detection is actually enough!
It is also likely to be camouflaged, or even optically invisible!
In addition, since it cannot be detected 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, even beyond The means of communication I know..."
As Yu Lao spoke, he observed Nie Yun's expression.
He used "the other party" many times in what he said just now, but Nie Yun didn't say anything about it. He obviously acquiesced in the existence of the "opponent", and he couldn't help but become more certain about his previous judgment in his heart.
Sure enough, it's not for me to find a place for the detector!Is the boss's opponent... suddenly so excited...
How could Nie Yun fail to discover Yu Lao's little thoughts, but sooner or later he would let them know, and he didn't tell them directly because even he himself knew very little about this group of Star B people, and he didn't even know whether the detector existed or not. question.
If I make an own mistake at that time, I will lose face as the boss!
Could it be said: "Oh, I made a mistake, it turned out that I was scaring myself, so embarrassing..."
In this way, the tall SOS organization has fallen to the bottom, okay?
"Well! You did a good job. I will send the detectors to inspect these two locations. No matter what the results are, as a reward, all the detection data of the Sea Wolf will be open to you!" Nie Yun smiled.
Yu Lao instantly became excited. This kind of space observation data is the most precious thing for an astrophysicist like him!
But he will soon discover that the detection data of the Sea Wolf is not only in the earth's orbit...
"By the way, your colleagues are almost here, as their managers and old acquaintances, go and say hello to them before that, it will also make them feel at ease.
In addition, I will arrange the gene reflux operation as soon as possible, and you are also ready to prepare. "Nie Yun gave Yu Lao a meaningful look.
"Hey! Boss, don't worry, leave it to me!" Yu Lao smiled...
