Space suits are often worn inside spacecraft as a safety precaution in case of loss of cabin pressure, and are necessary for extravehicular activity (EVA), work done outside spacecraft. Why the hell would we not know? Has anyone ever flawn in outerspace without suit or these are just theoretical considerations? 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: You would lose consciousness because there is no oxygen.

Space suits are often worn inside spacecraft as a safety precaution in case of loss of cabin pressure, and are necessary for extravehicular activity (EVA), work done outside spacecraft. I've never heard of Salyut before now. Working in Outer Space is a dangerous business as it is void of life supporting atmosphere that stops radiation, creates plentiful supply of air and creates a livable climate for us to survive.
