Why do astronauts wear only orange or white suit? Is it simply just the universal uniform colour defined for them? Why doesn’t anyone experiment with different colours?
Dude, they are astronauts. Every act of their is very precisely calculated, so it their suit design.
The two different suits they use are:Â
Advanced Crew Escape Suit, a.k.a Orange Suit and
Extra Vehicular Activities(EVA) Suit, i.e, White Suit
Orange suit is worn during lift-off. It is a high pressure suit, and very crucial for going to high altitudes, as pressure is very low there. The suit is also equipped with different stuffs for survival during launch or landing of flight. It has flares(for signalling, I guess), survival gear, medications, radio and a parachute.
But the colour orange is selected, as it is a very visible colour for search and rescue, including sea rescue.
White suit provides protection from outer space conditions, i.e., extreme temperature, vaccum, and flying debris. So it is thicker and heavier than orange one. It contains numerous layers of insulations and protective fabric. It contains breathable air, drinkable water, and temperature controls(for surviving in both hot and cold condition). A tether ties an astronaut, when he goes for a space walk. In case, the tether breaks, the suit can be controlled by a joystick inside the space ship.
Now coming to its colour, white reflects the heat better than any other colour, keeping astronauts cool. Also, a small white spot is easier to spot in dense black space.
