Would You Freeze In Space
If you were to step outside a spacecraft such as the international space station or on a world with little or no atmosphere such as the moon or mars without the protection of a space suit then the following things would happen.
Would you freeze in space. You would lose consciousness because there is no oxygen. If you do die in space your body will not decompose in the normal way since there is no oxygen. If you were not it would freeze.
Well space is really really cold. If we talk about going to interstellar space far away or shadowed from any stars the only temperature comes from the leftover glow from the big bang. The only way to transfer heat is via infrared radiation.
However in space there is no oxidation so decomposition cannot occur before the body either freezes if you are not near a source of heat or mummifies all the moisture will be sucked out of your body. In space there s nothing to insulate you so eventually you ll freeze to death. Hannah in the vacuum of space where it s a low pressure water boils at a lower temperature.
After water vaporizes in a vacuum the vapor could condense into ice or it could remain a gas. And in this case the vacuum of space. On earth heat can be transferred via convection but outer space is mostly nothingness.
This could occur in as little as 15 seconds. It expands creating gas and this could possibly cause you to explode or if you re sitting in the earth s orbit you ll eventually end up at about 4 degrees celsius in the sun. But the question here isn t about temperature differences but how efficiently heat transfers our of your body.
Though space is typically very cold most floating objects have a surface temperature of 454 8 degrees fahrenheit a person would not instantly freeze because heat does not transfer away from the body very quickly. But fortunately that loss of 100 watts of heat isn t all that much compared to the sheer mass of your body. If your body was mummified all biological processes would stop rather quickly so there would be no further breakdown of your body.
