An illustrated timeline of spacesuit design.

Some incredible Redditors have compiled a visual timeline of spacesuits designed for use in the space program. The chart includes both Soviet, Russian and American space suits as well as technology demonstrators, prototype, and  other suits that didn’t actually make it into space.

Check out the full-sized image here.

Interestingly enough, the G5C suit used on Gemini 8 isn’t included on here, although its immediate two predecessors are. Those were modified G3C suits and only used on that mission. Additionally, the Apollo A1C suit, a modified Gemini G3C, is not included either. That was to be used for the ill-fated Apollo 1 and cancelled Apollo 5 crewed missions.
