The biggest difference is gravity. On the earth, objects are attracted by gravity and produce weight, which can be firmly "fixed" on the ground; But in space, without gravity, everything will float in the air, so in space, whether you eat, bathe, sleep or go to the toilet, you must have special utensils, otherwise you will not be able to eat delicious food, sleep well, and even defecate will float around!

The environment in space is very bad, without gravity and air, the temperature will be as cold as ice and as hot as fire, full of all kinds of harmful rays. Therefore, astronauts must wear spacesuits with special functions when they want to leave the spaceship for outdoor activities to ensure their life safety.

Basic necessities of life for astronauts

have a meal

Most of the food is sealed in bags or cans and squeezed with toothpaste.

Dressed

The space shuttle is equipped with pressurization equipment, so don't worry about air pressure, just wear ordinary clothes.

have a bath

The shower equipment is a folding closed nylon cloth cover, which contains an electric heater and a nozzle, as well as a vacuum water absorber, which can suck away soap sewage.

Go to the bathroom.

The toilet is specially designed with foot covers and belts to help fix the posture.

sports

In space, if there is no exercise, muscles and bones will gradually shrink because of the loss of gravity, so astronauts should do at least 15 minutes of exercise every day.

sleep

In order to avoid floating in the air, astronauts have to fix themselves in sleeping bags when they sleep.
