Has Yang Liwei seen Chang'e?

Yang Liwei did not see Chang'e. Yang Liwei is the first Chinese person to enter space. Yang Liwei became the first Chinese to go into space, which is of great significance. His smooth return also marked a big step forward for our aerospace industry. Yang Liwei mentioned in his autobiography that when the spacecraft came back, it was moving violently, and he received a very strong shock and was injured as a result.

Yang Liwei went to space but did not land on the moon

To go to space, the spacecraft can enter orbit around the earth. The distance is short and the apogee orbit is hundreds of kilometers. The energy required for return is relatively small. Landing on the moon It is much more complicated, the distance is more than 380,000 kilometers, and orbit transfer is required. The energy required to return to the earth after landing is many times that of going into space, and the difficulty is much higher.

The moon is 380,000 kilometers away from the earth. This distance is about thirty times the diameter of the earth. In comparison, the area of ????Yang Liwei’s space is actually not large. The space demarcated by the moon’s orbit is the earth The center of the sphere is a sphere with a radius of more than 380,000 kilometers, while the spacecraft Yang Liwei is traveling on is only a sphere with a radius of 6,000 kilometers from the center of the earth.
