Affected by certain sci-fi movies, many people believe that the loss of space suit protection, astronauts will explode in space, is this really the case?
“If the astronauts want to go out of the cabin, they must wear space suits. The time for extravehicular activities is usually 3-6 hours. Although the space suit is called clothing, it is actually a small manned spacecraft that will be bad. The space environment is isolated to provide the environment needed for human survival.” Zheng Yongchun told the Science and Technology Daily reporter that if the astronauts are exposed to space without wearing a space suit, although they will die, they will not expand and explode as people think. .
Research data shows that if you do not hold your breath, the astronauts will be exposed to space for 10 seconds, there will be many minor problems, including sunburn, decompression may occur, skin and subcutaneous tissue is mild, reversible, no Painful swelling; exposure for about half a minute is unlikely to cause permanent damage; then, astronauts will lose consciousness due to hypoxia, and the damage of cellular hypoxia accumulates and dies in about a minute. It is worth noting that during this process, although the body’s air pressure is greater than the space pressure, the human body will swollen, but it will not explode.
