Astronauts Undergo Intense Training for Space Missions

The super abilities of Chinese astronauts are developed through rigorous training. Tasks on the Chinese space station are complex, requiring astronauts to undergo training in over a hundred different areas. One of the most challenging aspects is the sleep deprivation training in a confined space. Astronauts must complete various physiological tasks after being deprived of sleep for 72 hours in a room less than 6 square meters.
