Chapter 190 (2/2)
Because the sun, earth and moon are all behind it, the spacecraft in this position can clearly observe Mars and even the whole deep space.
At present, NASA's Wilkinson Microwave Anisotropy detector (WMAP) is measuring the residual thermal radiation after the big bang at L2 point.
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. Recently, they have been renamed Nie in the ”solar system investigation network” project. It is unlikely that the alien probes can engage in espionage activities under Nie Yun's eyes, which can be basically ruled out.
The third Lagrange point L3 is located on the earth day extension line opposite to the earth direction. It is separated from the earth by the sun. If the detector is at L3, then the difficulty of penetrating the stars to detect the earth may have broken through the sky, and can be basically ruled out.
So, only L4 and L5 are left!
They are located on both sides of the earth, which are the 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 areas!
”Well! From the perspective of celestial kinematics, this is the best possible position for the probe to exist! I prefer L4 and L5! ” Yu Lao said a similar judgment with Nie Yun.
”Well However, considering that the other party's technology may be far beyond the earth, the possibility of other locations can not be ruled outIf you want to be very hidden, 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 possible to do the appearance camouflage, even optical stealth processing!
In addition, since it can not be discovered by the existing detection technology of the earth, the communication means of the other party should not be the traditional radio technology, perhaps the laser communication with excellent confidentiality, which is extremely difficult to detect, or the more advanced quantum communication, or even the communication means beyond my cognition... ”
In the old side said, while observing Nie Yun's expression.
He used ”the other party” many times in his words just now, but Nie Yun didn't have any expression about it. Obviously, he acquiesced in the existence of ”the other party”, and in his heart, he couldn't help but affirm his previous judgment.
It's not to find the location of the detector for yourself! The boss's opponent I'm so excited
How could Nie Yun not find Yu Lao's careful thinking, but sooner or later, he should let them know. He didn't tell them directly because even he knew little about the group of B stars, and even whether the detector existed or not was a problem.
If you make an own oolong, as the boss will be very shameless, OK!
Do you say: ”Oh, I made a mistake. It's really embarrassing to frighten myself...”
In that case, the SOS organization on the tall will fall to the end, OK!
”Well! You've done a good job. I'll send a probe to inspect these two locations. No matter what the result is, as a reward, all the data from the sea wolf will be open to you! ” Nie Yun said with a smile.
In the old moment excited, this kind of space observation data, for his astrophysicist, is the most precious thing!
But he will soon find out that the data from the sea wolf are not only in earth orbit
”By the way, your colleagues are almost here. As their responsible person and old acquaintance, go and say hello to them before that, which will make them feel more at ease.
In addition, I will arrange gene countercurrent surgery as soon as possible, and you are ready to prepare Nie Yun took a meaningful look at Yu.
”Haha! Don't worry, boss. Leave it to me! ” Old Yu has a smile
