Super Mothership
Chapter 189 Lagrange Points
When the third child was frightening the children, the eldest was holding a small red flag in his hand.
"Cough! Good evening, all grandpas, this time we will be in charge of picking you up. Please keep order after boarding the boat for a while, and line up to follow my little red flag. If the flag does not fall, you are not allowed to run around and get If I lose one, my salary will be deducted! Thank you for your cooperation..."
This familiar tour guide's opening remarks made everyone's mouth twitch. Look at the people present. Apart from seven or eight hands and feet, it is convenient to move on their own. The rest are either in wheelchairs or lying on stretchers.
"Hey! Old Liang, these two people who came to pick us up look unreliable... What kind of SOS organization is really okay?" An old man with gray hair and a wrinkled face sat beside him. The old man with rosacea in the wheelchair said.
"Old Yu has confirmed it, so it shouldn't be a problem! Besides, with our old bones that are about to sink into the earth, what can people expect from us? With the technologies in our minds, maybe people really don't like it."
Before these scientists set off, they were informed of some information from Captain Ghost and the SOS organization in advance. No one could not say a word about Captain Ghost's black technology. The style of painting is really different from this era!
"Well, after seeing the old man for a while, we will know whether this is true or not..."
"Oh! It's here!" At this moment, the boss suddenly turned his head and said.
"Wow~" Under the moonlight, like a silver giant whale slowly emerging from the water, everyone slowly opened their eyes...
...
Earth's secret base.
"Lagrange point?!" Nie Yun looked at the excited old Yu in front of him and wondered.
Information about Lagrange points immediately popped into his mind.
Lagrangian point refers to some special position in space where the gravitational and centrifugal force of two celestial bodies are balanced at that point, so that the third object remains relatively stationary with the first two objects .
For example, if a satellite is placed at the Lagrangian point of the sun-terrestrial system, the satellite can remain relatively stationary with the sun and the earth, and can stably observe the two.
This property of Lagrangian points makes them of considerable strategic value in the space age!
Because it requires no or very little fuel to maintain orbital stability,
In the space age, the operating cost is low, and it has the best conditions to become a transportation hub!
This is like Shanghai's natural strategic location, 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 is still a blind spot in his thinking!
Immediately in his mind, he began to quickly analyze the possibility of alien probes existing at Lagrangian points...
There are a total of 5 Lagrangian points around a large celestial body such as a planet or a star. 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 a million miles from Earth.
Observing the sun from L1 can be free from gravitational interference. The point has now been occupied by the human "Solar and Heliosphere Explorer" (SOHO) and "Deep Space Weather Satellite".
L2 is also located about 1 million miles from Earth, but unlike L1, it is not between the sun and the earth, but on the extension 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 behind it.
NASA's Wilkinson Microwave Anisotropy Probe (MAP) is currently measuring the thermal radiation left over from the 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 were renamed Nie in the "Solar System Reconnaissance Network" project. The detector is unlikely to be able to engage in espionage activities under Nie Yun's nose, and it can basically be ruled out.
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 detector is at L3, then the difficulty of penetrating stars to detect the earth may have broken through. Skyrim can basically be ruled out.
Then, there are only two points L4 and L5 left!
They are located on both sides of the earth, and are the two intersections of the vertical bisector of the sun-earth line and the earth's orbit.
And these two points are one of Nie Yun's current detection blind spots!
"Yeah! Considering the kinematics of celestial bodies, this is the best possible location for the detector! I prefer the two points L4 and L5!" Yu Lao said a similar judgment to Nie Yun.
"Well... but considering that the other party's technology may far exceed the earth, the possibility of other locations cannot be ruled out...
If you want to be very concealed, it 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 very likely that the appearance of camouflage has been done, and even optical stealth processing!
In addition, since it cannot be discovered by the earth's existing detection technology, the other party's communication method should not be traditional radio technology, perhaps it is extremely difficult to detect, extremely confidential laser communication, or more advanced quantum communication, even beyond The means of communication I know..."
Yu Lao said while observing 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 obviously acquiesced in the existence of "the other party", and he couldn't help but feel more certain about his previous judgment.
Sure enough, it's not for yourself to find a location for the detector! The boss's opponent... I'm so excited all of a sudden...
How could Nie Yun not be able to find out about Yu Lao's careful thoughts, but he had to let them know sooner or later. He didn't tell them directly because even he himself didn't know much about this group of B-stars, and even whether the probe even existed or not. question.
If you make an oolong by yourself, it will be very embarrassing as a boss!
Could it be that he said, "Oh, I made a mistake, it turned out to be scaring myself, so embarrassing..."
If you say that, the tall SOS organization will fall to the bottom of it!
"Well! You did a good job. I will send detectors to inspect these two locations on the spot. Regardless of the results, as a reward, all the detection data of the Sea Wolf will be open to you!" Nie Yun said with a smile.
Yu Lao was instantly excited. This kind of space observation data is the most precious thing for an astrophysicist like him!
However, 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 person in charge and old acquaintance, let's go and say hello to them before that, it will also make them feel more at ease.
In addition, I will arrange the gene reflux surgery as soon as possible, and you are ready to prepare. "Nie Yun gave Yu Lao a meaningful look.
"Hey! Don't worry, boss, leave it to me!" Yu Lao smiled...
