What scientific and technological achievements has China made?

First of all, talk about the space station in China. 202 1, 10, 16, Shenzhou XIII manned spacecraft roamed the space, and three astronauts entered the Tianhe core cabin. More importantly, China's space station will usher in an era of long-term presence. Some media reported that the pilot was in good condition and expected to return in mid-April. According to another source, China has launched six missions this year. If the normal progress is followed, the China Space Station will be completed this year, and technical experts will be stationed in the space station in the future, which may further cooperate with other countries. Let me start with China's achievements in Mars exploration. What we are familiar with is that Tian Wen-1 landed on Mars and was selected as one of the top ten scientific progress in China in 20021year. More importantly, "Tianwen-1" laid a solid foundation for exploring Mars, and also got rid of the dependence on the West to a great extent, symbolizing China's position in the world space field. Of course, this is inseparable from the efforts of countless researchers in China, and it is also an important manifestation of the strength of a big country.

Finally, let's take a look at the observation results of the sun by special observation satellites. The sun is the source of life on the earth, bringing us light and heat. It is necessary for human beings to understand the trajectory of solar activity and finally realize the "space weather" forecast. In the past year, China's river satellite undertook the task of detecting the sun. The satellite is equipped with a magnetic suspension stabilization system, which can relatively separate the optical detection part from the propulsion stabilization part. Now, there is good news from China. The first comprehensive solar exploration satellite, the advanced space-based solar observatory, will be launched this year and is expected to run in orbit for no less than four years.
