UFOs in Low Earth Orbit
Here, Tang Zhenli, who had returned to the infirmary, was planning the return route on the desk beside the hospital bed, with Chu Wenqian’s reminder.
One after another dense formulas and equations are covered on the original white paper.
From time to time, Chu Wenqian, who came to watch curiously, frowned.
In my heart, my impression of Tang Zhenli was even more profound…
Although she can’t understand most of them, she can also guess that this is the formula for calculating the orbit…
The question is, when did Tang Gong know so much about the field of astronomical orbits?
For a while, Chu Wenqian looked at Tang Zhenli with a slightly complicated look. This man… The more you get along with him, the more terrifying he can feel… Charm, temperament, knowledge. .
“One forty zero” and these qualities are not static. Every once in a while, she can see new things in Tang Zhenli…
This kind of feeling is like this person is always making progress. The most terrifying thing is that Chu Wenqian can’t see the end of this kind of progress…
More importantly, this is only what she saw when she and Tang Zhenli got along for a short time…
If Tang Gong had been like this since he was a child, it would be hard to imagine how much Tang Gong’s brain and brain circuits surpassed that of ordinary people…
No wonder sister Tianxian fell in love at first sight when she was a child, and fell in love with Tang Gong…
If that’s the case, then it’s not hard to explain…
Who can’t stand it?
A man who exudes this kind of charming temperament all the time, no one can stand it..
For a while, Chu Wenqian looked at Tang Zhenli’s eyes gradually lost…
On the other hand, Tang Zhenli didn’t know that Chu Wenqian, who was beside him, was talking about him secretly in his heart.
At this moment, he is concentrating on planning the fastest route for the ‘Phoenix’ to return.
That’s right, planning the best route in space where there is no up, down, left or right!
It sounds incredible, but Tang Zhenli knows that it can be done in theory!
And all of these are the enlightenment Tang Heguang gave him when he was a child.
As an expert in astronomical orbital science, Tang Heguang is only in low-Earth orbit, but what Tang Heguang said to Tang Zhenli when he was a child impressed him deeply…
It looks boundless, and in the vast and boundless space, there is also a direction!
And the basis of this sentence is from the cognition of human beings themselves!
This cognition is the cognition of the coordinate system!
On the surface of the earth, we usually mean the opposite direction of gravitational acceleration, and left and right are defined according to the direction of self and rotation.
To put it simply, it is to determine the approximate inertial reference frame of the earth’s surface, and then combine with its own attitude to define up, down, left and right.
while in spaceAmong them, there is a similar coordinate system.
For example, the most commonly used coordinate system in astronomy is the solar ecliptic coordinate system. The origin of this coordinate system is at the center of the earth, the x-axis is the straight line from the earth to the sun, the z-axis is vertical to the north of the x-axis, and the y-axis is the sum of the x-axis and The z-axis forms a right-handed Cartesian coordinate system.
Simply speaking, this kind of coordinate system is to use the earth and the sun as reference objects to determine the specific position of an object in the solar system.
But what Tang Zhenli is doing at this moment is not using the solar ecliptic coordinate system. Now he is using his own estimation of the direction and speed of the ‘Phoenix’ departing from the earth to determine a new coordinate system.
The reference objects of this coordinate system come from the earth and the moon. Although the reference range of this coordinate system is not as wide as the solar ecliptic coordinate system, it is more accurate.
In other words, Tang Zhenli is using this coordinate system to determine the specific position of the “Phoenix” in the coordinate system he created at this time.
Although it sounds a bit magical, it is indeed feasible!
And it takes a whole day to do this job. If Chu Wenqian hadn’t persuaded him to sleep in the end, Tang Zhenli probably would have skipped this sleep cycle..
After going through this sleep cycle, Tang Zhenli woke up and started to calculate again from the blank paper.
Although Tang Zhenli’s understanding of astronomical orbits is not very deep, with the help of the system, he is able to handle it with ease at this moment……
Finally, after half a day’s calculations, Tang Zhenli finally came up with a return route that only he could see!
If you want to talk about why only Tang Zhenli can understand it, then you have to talk about the coordinate system newly established by Tang Zhenli.
If ordinary people want to agree with this coordinate system, they have to go through a series of cognitive transformations, otherwise it is easy to substitute their own cognitive coordinate system into it.
In other words, Tang Zhenli will act as a human navigator during the next return journey, guiding the ‘Phoenix’ on its difficult return journey.
And in the afternoon of that day, good news came from the maintenance team of the power system.
All three Qinglong power modules have been successfully activated and are turning successfully.
As soon as he heard the news, Tang Zhenli came to a cabin on the bow of the current “Phoenix”.
When the main control room was damaged, the staff of the “Phoenix” used the only cabin at the bow as a temporary command room.
And outside this cabin is the space-based laser cannon that is hailed as the “Sword of Slaying God” by the crew of the “Phoenix”!
In the past half a month, all the crew members of the “Phoenix” basically knew that the hero of Tang Gong’s successful killing of the gods was the strange machine that was not paid attention to by everyone when the “Phoenix” took off. equipment!
That is, the space-based 4.2 laser cannon!
Under this premise, the awe of the crew of the “Phoenix” for this space-based laser cannon has also accumulated over time.
After all.. It is such a small and unremarkable instrument that successfully saved all mankind at a time when all mankind was in crisis!
Fortunately, the location of this space-based laser turret is quite ingenious, and its size is small, so it didn’t receive too much damage from the previous shock wave.
But even so, some crew members still come here from time to time, just to admire the sharp weapon of the ‘Slaying God’!
But now that the cabin at the bow of the ship is used as a temporary command room, there are naturally fewer people coming.
