Spy satellites can penetrate clouds and take "crystal clear" photos. How did this happen?

I think you may have a deep misunderstanding about spy satellites because of their thick atmosphere and cloud interference. In fact, ordinary satellites rarely use traditional camera shooting methods, which was actually an backward technology in the 1960 s and 1970 s. Now spy satellites are equipped with many sensors in the name of remote sensing and resource detection, including various bands, and because of the need for high resolution, there is basically no continuous video recording function. Most of them are continuous videos formed by stitching CCD camera images and multiple photos, and only aerial photography can ensure the quality.

From ancient times to the present, the relationship between world powers is like a hedgehog, approaching cautiously for fear of being hurt. The current international situation is no longer a unipolar world dominated by the United States. After Russia remained silent, he began to exercise power in the Middle East. In Asia, China is actually a rising star of Ran Ran, which has become a necessary condition to test the military strength of the other side in this situation. American spy satellites once took a group of rare photos in China.

This caused them great shock. This is a set of photos about our military airport. Because the location is in the pear trees in the mountains, it gives people a feeling that there is no way to go. You know that if there is a war, it is most important to destroy each other's strategic weapons, but how can these planes hidden under the mountain be destroyed?

Why do you think these things are really unknown to ordinary people? After all, it is a professional thing in science and technology. I only know that countries are exploring outer space more and more frequently now, especially after China successfully brought back moon samples with Chang 'e-5 probe, other countries are gearing up and will continue to explore outer space one after another. We should not only explore all the unknown things in outer space, but also some unknown things about the earth. This time, the Russian ionospheric satellite mainly measures how the earth and the ionosphere are transformed, and the changes and intensities of magnetic and electric fields near the earth. At the same time, it will also measure proton and electron flow at a height of about 800 kilometers.

To tell you the truth, I have a headache when I look at these electron flows. We all learned it in high school. Physics knows the ionosphere. These are all related to energy. So I think Russia's exploration this time may be to understand how the ionosphere of the earth moves, or that they can be used by human beings in the future. Then in 20021year, Russia will put these two satellites into orbit from the Eastern Space Launch Site.

Since this campaign is so big, I think if the Russian research is really successful, I think it will be a great progress in human history. Because we know that people's lives have actually changed a lot since they learned and gradually mastered and used nuclear energy, if we want to find energy from other aspects, besides solar energy, ocean energy and tidal energy, we should study the ionosphere of the earth. The Japanese side indicated that the satellite was a cube made of wood with a side length of 10cm. In order to withstand the pressure of satellite ascension, wood has not been forced to deform several times, so it is said that it is made of Japanese magnolia bark, which has very strong anti-deformation ability. After this satellite launch, it will stay in the orbit of the International Space Station for up to one year. At the same time, Japan's space station will monitor the deformation of wood at any time. ?
