Why do we have to wear space suites in space?

Answer 1

So we can:

breathe
communicate with Mission Control
not have our blood boil away from the lack of pressure in space
be protected from micrometeorites and other space debris
have somewhere to wear our cool mission patches

Answer 2

One reason astronauts wear the suits is to protect from extreme temperatures. The suits circulate water in them to regulate temperature, and has massive amounts of insulation. Without that protection an astronauts blood could literaly freeze or boil.

Another reason, There is no oxygen in space and the suits have self-contained breathing devices in them, so they can breathe

Answer 3

The short answer to that is it's extremely cold in space, and there is no oxygen, so we need the suits for warmth, and to have an enclosed system, so the oxygen in our air tanks ends up in our lungs instead of just floating off into space!

Answer 4

White dwarfs p.c.. between .17-a million.3 photograph voltaic plenty or 50-4 hundred,000 situations the mass of the Earth right into a sphere with .9-2.2 situations Earth's diameter. a very cooled black dwarf might, if something, probably be even denser. Offhand, except you have been in an extremely stable completely robotic physique i individually doubt you should proceed to exist the gravity. of direction, the earliest you should objective this feat the two way would be ~a million X 10^15 years interior the destiny, or whilst the universe is ~seventy 5,000 situations its contemporary age. this is a low-end estimate for the way long a white dwarf will take to relax right into a black dwarf.

Answer 5

Under pressure at the surface of the earth, air is dense enough that you can inhale and exhale, and 20% oxygen is enough to supply your body. At higher altitudes, the pressure on your body is less so you move air in and out of your lungs at a much smaller density; you can still survive if you breathe 100% oxygen at a low pressure. But in space you have zero pressure, so whatever oxygen you could breathe in would be so thin it still wouldn't sustain your life, even at 100%. Your lungs can't hold any appreciable pressure, they only move air in and out at whatever pressure you have around you.

The only solution is a pressurized suit, in addition to the other reasons given above.

Answer 6

your body is under pressure right now, at about one "atmosphere" (the weight of the atmosphere on you). you need to equalize the pressure between your body and the atmosphere so that you dont get squished. so when you go into space, you tend to explode because your body has high pressure compated to the no pressure of space. to equalize, you explode. if you wear a space suit, it keeps a pressure of 1 atmosphere on you, so you dont explode. its materials can withstand the stress.

Answer 7

you would not be able to breathe and the suns rays would be extremely hot if you didn'y wear a space suit

Answer 8

The same reason we have to wear earth suits on earth.
Indecent exposure?

Answer 9

So we don't die - space is not very conducive to human life.

Answer 10

Well, there is no cute aliens there to flirt with if we wear bikinis..hehehe
