Space spirit

In order to adapt to the harsh external vacuum environment of leaving the cabin and entering space, astronauts must enter the low-pressure chamber to exercise their super endurance in order to overcome the threats of low pressure and hypoxia that may occur during spacecraft flight. Entering the low-pressure chamber is like climbing Mount Everest on a snowy plateau. The hypobaric chamber can simulate the oxygen environment at an altitude of 5,000-10,000 meters, but this kind of training is completely different from the plateau environment. Because when climbing on the ground, you can gradually climb from low to high, and there is a gradual adaptation process. However, astronauts perform low-pressure cabin exercises. From the moment they enter the cabin, they immediately ascend to an altitude of 5,000 meters above sea level at a speed equivalent to 15 meters per second without wearing oxygen masks. It only takes a few seconds to find the cabin. The astronauts inside developed symptoms of chest tightness, headache, and nausea. However, they persisted in pushing the limits even though they were breathing heavily. The height of the low-pressure chamber is 6,000 meters, 7,000 meters, and continues to rise to 10,000 meters... Training in a low-pressure chamber is definitely a test like a life and death experience! However, they challenge the limits one subject after another, creating new selves in these challenges again and again, and constantly climbing towards new goals.

There is a touching saying from a Chinese astronaut: "From the day we joined the astronaut corps, we have been always ready to extend the flight trajectory of a nation into the vast space outside the atmosphere." They always hold on to one belief: "Get on the spacecraft, We are flying warriors; when we step off the spacecraft, we are ordinary soldiers. We are a special team, but there can be no special soldiers in this team!"
