What do space suits do for astronauts?
Space suits protect astronauts from micrometeorites that may hit them when they are space walking, protect the astronauts from rapidly changing temperatures, the suit itself is also pressurized to make sure the astronauts blood circulates around the body and not just the bottom of the body. It is also used to help protect the astronauts from radiation (solar and infrared), and the lack of oxygen in space.
