Why do astronauts wear bizarre suits and travel in weird spacecrafts?

      The shuttle of the missioners is especially designed to defeat the space gravity and Newton's Law: special cabins with beds, ways for eating…

       Moreover in space, there is no air nor air pressure, so it is theoretically impossible to breath by our own out there. The temperature is extremely low, unless you face the sun's rays that could simply burn you as long as there is no atmosphere or any layer (e.g. ozone layer) to protect the body. That is why Astronauts must wear spacesuits whenever they leave a spacecraft and are exposed directly to the environment of space. Without all this protection, an astronaut would quickly die. "Spacesuits are specially designed to protect astronauts from the cold, radiation and low pressure in space. They also provide air to breath, water to drink and even a built in toilet! Wearing a spacesuit allows an astronaut to survive and complete his mission."
