21 Facts About Space suit

Space suit or spacesuit is a garment worn to keep a human alive in the harsh environment of outer space, vacuum and temperature extremes.

The first space suit worn by a human in space was the Soviet SK-1 suit worn by Yuri Gagarin in 1961.

Space suit must perform several functions to allow its occupant to work safely and comfortably, inside or outside a spacecraft.

Generally, to supply enough oxygen for respiration, a space suit using pure oxygen must have a pressure of about 32.

Virtually all workable space suit designs incorporate hard components, particularly at interfaces such as the waist seal, bearings, and in the case of rear-entry suits, the back hatch, where all-soft alternatives are not viable.
