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.
Can we walk on mars without a spacesuit.
Atmospheric pressure on mars is very low.
Lack of oxygen will cause you to los.
You would become unconscious within 15 seconds because there s no oxygen.
If you were to step outside a spacecraft such as the international space station or onto a world with little or no atmosphere such as the moon or mars and you weren t wearing a space suit here s what would happen.
Also i suspect that cooling the suit would be easier since there s atmosphere so they can get away with a less bulky cooling system than what was used on the moon.
Insofar as the human body is concerned you might as well be in empty space.
How could this be possible.
If you were to venture there without any gear you would survive for less than 2 minutes provided that you held your breath.
Without your spacesuit you d either freeze or instantly turn into a carbon brick depending on which side of the planet you were standing on.
Yup a spacesuit for mars should need less protection than one for the moon since it s farther from the sun and has at least a little atmosphere to block radiation.
