Whats inside a space suit
Under the suit astronauts wear another lay of clothes this layer covers their body except for their head hands and feet. Tubes are woven into this layer to keep the astronauts cool. On the back of a space suit there is a backpack that holds oxygen. This backpack also releases carbon dioxide that the astronauts have exhaled. The backpack also holds the electronic system for the suit, and a fan that moves the oxygen throughout the suit also the water cooling system. Connected to the back of all space suits is something called SAFER. SAFER is a tool that is used when an astronaut floats away from the space station they can use SAFER to get back safely.
