The history of NASA Space Suits and their “imperfect” measures


With the start of the Apollo missions the space suit changes radically: it must offer astronauts protection from the lunar environment, with temperatures ranging between 120 ° C at midday and 170 ° C at sunset, it must be able to be worn for long periods of time up to 8 hours and must allow to move easily and guide the rover on the surface of the satellite.
Thus the A7L suit was born, much more flexible than the previous ones, even if pressurized. It is the first suit to which an external survival system (air conditioning, respiration and pressurization) can be attached that does not make the “umbilical” connection with the spacecraft necessary.
The critical element of the Apollo suit is the gloves: less thick than the other parts of the device to allow the astronauts to handle tools and collect samples, they must however be resistant to wear and cuts that could create problems of depressurization.
