After the successful moon landing of India's Chandrayaan-3, the popularity did not drop, but many netizens questioned: the Chandnament-3 moon landing was a fake and was filmed in the studio.
I summarized the points questioned by netizens:
1: Switch live broadcast to animation
When the Indian Chandrayan-3 lander was in the last 19 meters, the live broadcast screen suddenly switched to animation.
2: Chandrayan-3 is similar to China's release of lunar topographic maps
Self-media "Kunyu Jisheng" said that the landing site of India's Chandrayan-3 is exactly the same as the lunar topographic map released by China, and some people in the comment area said: the duplicate check rate of these two maps is too high, and you can see plagiarism at a glance.
But these two pictures are originally a place!
The picture says "Topographic map of the moon released by China", but above it is the logo of India's ISRO.
In fact, this picture was originally released by ISRO after the successful moon landing on Chandrayan-3, not released by China, this is not a fake, it is a Bo advocate crown Li Dai, took the picture of others ISRO as China, and then conversely said that India's moon landing was fraudulent.
3: The direction of the light source is inconsistent
Some people on the Internet questioned that the moon rock shadow was left for a while and right for a while, suspecting that there were two light sources here where the photo was taken.
I see that there are many doubts on the Internet about the Chandrayaan-3 lighting problem, all of which mean that there is more than one light source.
In response to these doubts, we will analyze one by one to see whether India's moon landing is true or not!
Switching from live moon landing to animation: China has a precedent
In fact, you all forgot that when we landed on the moon on Chang'e 5, the live broadcast screen also became an animation, and some netizens complained:
"The whole cartoon, and it's funny to laugh at the video taken by people."
At that time, some people also questioned the falsification of our Chang'e-5 moon landing, not only because it was an animation, but because the broadcast screen was interrupted, and at that time there were still people who were worried that the mission failed, and then they were stunned and found that China announced the successful landing of Chang'e-5.
Some people abroad who don't like China, when they saw the Chang'e-5 signal interrupted, thought that our probe had failed to land, and after the subsequent mainland announced the success of the moon landing, they even questioned our fraud!
When Chang'e-3 landed on the moon, it did release real shots and simulated animations, and the simulated animation was very smooth, but the images taken by the landing camera were stuck, and some people said when watching the live broadcast:
"Why is our camera so stuck?"
During the live broadcast, the real shooting of the moon landing became an animation, not only India did this, China has already done it, and when Chang'e-5 landed, there was a signal interruption, why is this?
The specific reason is this, the moon is an average of 380,000 kilometers from the earth, and it has to pass through a vacuum layer, ionosphere, atmosphere and other different media, the transmission of signals is by electromagnetic waves, electromagnetic waves in different media will have some losses, coupled with some disturbances in the atmosphere, will cause some unstable situations.
For the aerospace team, the highest priority in the landing process of the probe is to ensure the transmission of measurement and control data, the real-time picture taken by the camera with the probe can only reduce the resolution and draw frames to transmit, this is when Chang'e-3 landed, although there are real pictures, but the pictures we see are one card and one card, one picture stays for a long time, and the next picture will be updated, not as smooth as the video.
Although the picture reduces the resolution and draws frames to transmit, it has not occupied so many resources as much as possible, but the bandwidth of the communication link is limited after all, when necessary, abandon the transmission screen, but also to ensure that the attitude data can be transmitted.
Therefore, in the process of landing on the moon, the use of animation simulation instead of real shooting is based on the priority of "moon landing first", the real shooting picture is dispensable, although China landed for 3 months, only Chang'e-3 put a real picture at the same time as landing, and it is not a full real shot, when the moon is about to land, the real shot is released, the picture is still a card and a card.
Moreover, the animation simulation is not casual, but simulates the real moon landing based on telemetry data, and the state of the detector in the animation is the same as the real situation.
From this point of view, the Indian Chandrayaan-3's approach is not at all problematic.
The direction of the Chandrayan-3 light source is inconsistent
Some people say that the direction of the light source of Chang'e-3 is inconsistent, but this I think is wronged by the Yuechuan 3.
Some people analyzed that the shadow of the moon rock is on the left, and the shadow of the moon ship is to the right. But have you thought about it, the moon rock shadow wants to do it because it is a crater, the shadow should have been in the pit, and there is no problem with the direction of the shadow.
On the contrary, the shadow angle proves that Chandrayaan-3 is located at high latitudes of the Moon.
For a long time, we have thought that Chandrayaan-3 landed at the south pole of the moon, but in fact it is not, the lunar landing site of "Chandrayaan-3" is located at 69.37 degrees south latitude, 32.35 degrees east longitude, the south pole of the moon is located in the area south of the south latitude of the moon, and Chandrayan-3 is close to the south pole of the moon, but it is not the south pole of the moon.
The lunar south pole latitude is high, the sun's position angle above or below the horizon will not exceed 1.5°, and the shadow will become very long. The landing site of Chandrayaan-3 is close to the south pole of the moon, and it can be seen from the picture released by India's Chandrayan-3 that its shadow is indeed very long and indeed located at high latitudes of the moon, which not only indicates that the moon landing was successful, but also that it successfully landed near the south pole of the moon.
Chandrayaan-3 carries a 26-kilogram lunar rover, the wheels of which are printed with the national emblem pattern, that is, the stone carvings at the top of the Mauryan Ashoka pillar, each step leaves clear "footprints" on the lunar surface, if there is no human destruction, these footprints will remain on the moon for tens of thousands of years.
After the landing of Chandrayaan-3, the "Pragyaan" lunar rover turned on the "rush mode", which is indeed the rush mode, and has traveled 8 meters, you know, after working on the lunar surface for 972 days, a total of 118.9 meters.
Pragyaan is designed for a very short lifespan of only 1 month, equivalent to 14 Earth days, and after entering the night in the landing zone, the lander and rover will lose power and cannot continue working.
This is because the moon has no atmosphere, and the temperature at night is very low, the temperature at night can drop below minus 190 °C, and the daytime temperature will be as high as 127 °C. The reason why the continental Jade Rabbit lunar rover can spend the night on the moon is because the jade rabbit uses the radioactive element polonium 210 to heat the lunar rover during the moonlit night to ensure that the instrument will not be damaged by low temperature.
"Pragyaan" did not have a design to deal with the moonlit night, so he had to take advantage of the fact that it was moonlight and hurry around, and when it was moonlit night, he could not move.
The lander and lunar rover cannot spend the night on the moon, the lifespan is too short, and the scientific results detected are limited, which does not seem to be cost-effective. However, for India, the main purpose of Chandrayaan-3 is no longer for scientific research results, but the success of the moon landing, as long as the moon landing can be successful, the scientific load can be brought less, the most important thing is to master the lunar landing technology, scientific exploration can be handed over to the next mission.
In this respect, India succeeded. #挑战30天在头条写日记#
