SOLAR SYSTEM

Detailed explanation-1: -If an astronaut is exposed to a space vacuum without protection, other nasty stuff would happen, too. Without atmospheric pressure to balance things out, the unfortunate space traveler’s final breath would expand in his or her lungs, tearing the delicate gas-exchange tissues that line them.

Detailed explanation-2: -Contrary to how the lungs are supposed to function at atmospheric pressure, oxygen diffuses out of the bloodstream when the lungs are exposed to a vacuum. This leads to a condition called hypoxia, or oxygen deprivation.

Detailed explanation-3: -Outer space is not completely empty; it is a near-perfect vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays.

Detailed explanation-4: -Vacuum cleaners work by creating a pressure difference-if there is no pressure, they do not work. Therefore, the vacuum cleaner will not work in space.

Detailed explanation-5: -Vacuums are indeed lethal: Under extremely low pressure air trapped in the lungs expands, tearing the tender gas-exchange tissues. This is especially grave if you are holding your breath or inhaling deeply when the pressure drops.

Detailed explanation-6: -The short answer is the astronauts and cosmonauts (that means a Russian astronaut) bring oxygen from Earth, and they make oxygen by running electricity through water. This is called electrolysis. The air and water on the Space Station all originally came from Earth.

Detailed explanation-7: -The Earth’s atmosphere contains an abundance of oxygen. In contrast, space has a lack of it. Without oxygen you wouldn’t be able to breathe and would become unconscious after about ten seconds. Unfortunately, even trying to hold your breath, to keep all your oxygen in, wouldn’t work in space.
