World Reading Day on 23rd April-Tenveo
It is not the work of one man or even a group of men. It is a historical process that humanity carries out in accordance with the natural laws of human development.-Yuri Gagarin

April 12nd is the International Day of Human Space Flight.  Sixty-one years ago today, Soviet cosmonaut Yuri Gagarin completed the world's first manned space flight aboard the Vostok 1 spacecraft, which orbited the Earth at an apogee of 301 kilometers for one hour and 48 minutes before returning safely.  

Through the ages, the dream of "flying" has never stopped.  In different mythological systems, there are angels with wings and immortals flying in the clouds, although in different forms, they all express the yearning of human beings for flying in the sky.  

Wan Hu of Ming Dynasty was the first person in the world to put the idea of flying into practice.  He tied 47 homemade rockets to a chair and sat on it with a kite in his hand, ordering people to fire and launch, in an attempt to fly with the power of rockets.  Unfortunately, the rocket exploded, and he not only failed, but lost his life.  Although it was a very primitive attempt to "fly", it seems very funny now, but that hasn't stopped people from "flying".  

After World War II, manned spaceflight developed rapidly.  Much was achieved during the "space race" between the United States and the Soviet Union.  Since the late 1950s and early 1960s, the two countries have done a lot of preparation.  After many experiments, the Soviet Union was the first to send a man into space in 1961.  In an effort to even up the game, President Kennedy announced that by the end of the 1960s, the United States would put a man on the moon and return him safely. This became known as the Apollo program.  

In the years since, the two countries have been engaged in fierce competition: "three-man flight", "space walk", "space docking", "first landing on the moon", "the first manned space station"...  Humanity pushes the envelope every time, but every time it breaks new ground.  

In the 1970s and 1980s, China made great progress in space technology, which laid a solid foundation for manned space technology research.  In 1992, China's manned space program was approved by the government.  In 1999, China's first unmanned experimental spacecraft shenzhou I took off and successfully completed its mission.  In 2003, China successfully launched its first manned spacecraft, Shenzhou V.  

In the following ten years, China's manned space career has made great progress.  In October last year, the Shenzhou 13 manned spacecraft was successfully launched. While in orbit, the three astronauts carried out tests on key technologies for the assembly and construction of the space station and examined the performance of various systems in the project.  Accomplished a number of tasks excellently.  

In a few days, three astronauts will return to Earth on a business trip, marking the end of China's space station's key technology verification phase. Let's wait and see.
