How do primary school students tell about life in space?

Space is a magical world full of charm, and space life is a magical topic full of charm and curiosity.

The space environment is very different from the earth environment. There is no air, no gravity and dangerous space radiation. Of course, there is enough air for you to breathe in a closed space station or space shuttle cabin. Good spacecraft shielding materials can effectively block space radiation, but "weightlessness" will bring some troubles to life.

If you live in space in the way of the earth, you will definitely make a lot of big jokes. For example, when eating, you carry a bowl of rice, and the rice will float all over your cockpit. You may not be able to eat anything with your mouth open. When you keep your mouth shut, rice grains may float into your nostrils and choke you to death. You want to sleep comfortably in bed, but you will find that there is no upper and lower boundary in space, and there is almost no difference between "lying" and "standing" ...

Some people sleep with their hands or legs outside the quilt. This seems normal on the ground, but it is very dangerous in the space environment. Space weightlessness, people's limbs will swing from side to side without being dominated by the trunk during sleep. A former Soviet astronaut once put his arm out of his sleeping bag to sleep. When he woke up, he suddenly found two big hands floating on his face, which startled him. It turns out that these two fluttering big hands are his own. Shocked or trivial. If the uncontrolled "free" hands and "free" feet accidentally touch any switches or instruments after the astronauts fall asleep, wouldn't the safety of the space capsule and the life of the astronauts become a big problem? So when sleeping in space, be sure to put your hands and feet in your sleeping bag.
