Is There Pressure In Space
Pressure may be detected from the molecule of air or water hitting you.
Is there pressure in space. Pressure is no longer sufficient to keep body fluids from boiling. In space outside of the earth s atmosphere there are almost no molecules in the gas that surrounds the international space station. The pressure in outer space is so low that many consider it as non existant.
With the helmet visor and gloves locked in place the suit fully encloses the astronaut in an air bubble inflated to 3 5 pounds about the same air pressure as a person would find 30 000 feet above earth. The absence of molecules means that the air pressure is extremely low in fact it is almost zero so it is nearly a perfect vacuum. The pressure in outer space is so low that many consider it as non existant.
It has a pressure of 1 322 10 11 pa. Spacesuits for the space shuttle era are pressurized at 4 3 pounds per square inch psi but because the gas in the suit is 100 percent oxygen instead of 20 percent the person in a spacesuit actually has more oxygen to breathe than is. Most space suits use around 30 39 kpa of pure oxygen about the same as on the earth s surface.
As we travel into orbit outer space and ultimately intergalactic space the pressure varies by several orders of magnitude. Since there is very little air and hardly ever water hitting you in space pressure is almost zero or negligible. Atmospheric pressure is variable but standardized at 101 325 kpa 760 torr.
