China is rapidly expanding its footprint in the space sector. China wants to overtake America in space in the future. For this purpose, it has recently sent three of its astronauts to the Tiangong space station.
If we talk about these three astronauts, they include Commander Cai Shuzhe and two new astronauts, Song Lingdong and Wang Haoze. These people will stay at Tiangong Space Station for about 6 months and work on many projects there. Apart from this, these astronauts will also do space walk. Let us tell you about it in detail.
What is a space walk?
What is a space walk? "extravehicular activity" Also called (EVA). This means that astronauts go out of their space station or spacecraft to work in open space or to investigate something. This work done in open space is called space walk in the language of science.
How did space walk start
Know the history of space walk. Talking about it, it started in 1965, when Soviet astronaut Alexei Leonov stepped into space for the first time. He decided that he would exit the space station in his space suit. He also went out into open space for the first time and worked there for about 12 minutes. After this, in 1966, America’s NASA organized its first EVA program. It is said that since then space walk has become an important aspect in space science.
What is the suit for space walk
Space walk To do this, the astronaut has to wear a specially designed space suit. This suit is equipped with many features, such as temperature control, oxygen supply and safety equipment. Apart from this, when astronauts exit their spacecraft, their suit is connected to the spacecraft through a cable. This is so that astronauts do not get swept away in space.
