@JackEnrod @wonderofscience that's what I have been thinking too. I am sure those view glasses could handle a bump or two, but I would have need a space underwear change every time I felt I was loosing my balance

The Apollo space suits were actually very cleverly designed with the inner pressure vessel being covered by many layers of various protective fabrics (including fiberglass cloth IIRC).

Even if the suit did somehow get a tear, they were only pressurized to 3–5 PSI (the partial pressure of oxygen in air) so if the astronaut found the leak they could probably just cover it with their hand and seal it until they got back to the capsule and could either abort the mission or permanently reseal it (dunno if they had a method of repairing suits in Apollo yet, I'd assume so). They could connect to the other astronaut's space suit as well if their air supply started running out.

The space suit used in the Apollo missions without all the outer protective layers, showing just the internal pressure vessels. There's rigid fabric in the torso, and what looks like corrugated semiflexible plastic in the limbs (so they don't inflate out into round balloons)
The full space suit from the moon, it is substantially thicker because of all the padding, insulation, and other protective layers

I just realized that engineers are mostly nerds who watch alot horror or disaster movies who can think of any horror scenario imaginable and find a solution to those scenarios.

Apparently, that superpower didn’t transfer from atoms to bits.

@nytpu @JackEnrod @wonderofscience Thank you for this insightful and probably-correct post. I went to Space Camp four times and was a space geek as a kid, so I already knew that the suits weren’t pressurised to 1 bar.

Doesn’t change the fact the astronauts were probably had a bit of mild panic at each fall that they could tear some sort of hole in the suit, but you have articulately and clearly explained why that even that fear on the Moon would have been more or less irrational: the chance of a life-threatening situation was fairly low.

You've just ruined tons of sci-fi where someone dies or has a major emergency from a tiny leak that empties the high pressure suit in a matter of minutes or seconds. It's cool to learn how they actually worked though! 😂 😁
