SOLAR SYSTEM

Detailed explanation-1: -This means that there is no air pressure in space. Therefore, spacesuits are inflated with a certain amount of air, just like a balloon, to apply the necessary external pressure to the astronaut. Thus, the body fluids of astronauts can remain in liquid form during a spacewalk.

Detailed explanation-2: -Also because of the lack of atmosphere, the astronauts would be subjected to extreme temperatures in outer space. Hence space suits are designed to protect astronauts against extreme heat and cold.

Detailed explanation-3: -On the back of the spacesuit is a backpack that houses the supplies and equipment to make the suit work. This backpack contains the oxygen that astronauts breathe and that pressurizes the suit. A regulator in the backpack keeps the suit at the correct pressure.

Detailed explanation-4: -Like a tire, a space suit is essentially an inflated balloon that is restricted by some rubberized fabric, in this case, Neoprene-coated fibers. The restriction placed on the “balloon” portion of the suit supplies air pressure on the astronaut inside, like blowing up a balloon inside a cardboard tube.

Detailed explanation-5: -Spacesuit requirements It must provide: a stable internal pressure. This can be less than earth’s atmosphere, as there is usually no need for the spacesuit to carry nitrogen. Lower pressure allows for greater mobility, but introduces the requirement of pre-breathing to avoid decompression sickness.
