Detailed explanation-1: -Spacecrafts must provide their passengers with oxygen to breathe. Spacecrafts carry their own sources of oxygen and nitrogen. These gases are circulated throughout the spacecraft to provide similar air to the one we breathe on Earth. Astronauts must also carry their entire food supply when they travel to space.
Detailed explanation-2: -Information about the items that astronauts take with them is usually kept very private, but typical PPK items include family photos, organizational flags, t-shirts, ball-caps, books, religious texts, and personal mementos.
Detailed explanation-3: -Above the 63, 000-foot threshold, humans must wear spacesuits that supply oxygen for breathing and that maintain a pressure around the body to keep body fluids in the liquid state. At this altitude the total air pressure is no longer sufficient to keep body fluids from boiling.
