They breathe artificial "air" that is almost the same as the air on Earth. It is made up of 20% oxygen and 80% nitrogen similar to the air we breathe and it is at a pressure of 14.7psi which is the same as the atmospheric pressure on earth.
Yes there is. No pressure would mean a vacuum, and astronauts would not be able to breathe!
The Apollo 13 astronauts were not on the space shuttle.
Astronauts aboard the space shuttle were primarily NASA astronauts, astronauts from Canada, Europe and other countries.
it has an air tank and keeps the air that you can't breathe in out.
it is advantageous for astronauts to live on a space station rather a space shuttle because a space station allow astronauts to stay and work extended time . A space shuttle is a space craft to transport astronauts , satellites, and other materials to and from space.
