its weird how we can hear recordings of the astronauts talking while they are on the moon, and yet we cant hear the valves open and close on the breathing apparatus.

The dupes will explain that the reason we cant hear the valves open and close, is because they didnt have valves, and the astronaut was supplied with a constant flow of breathing air,

Which would have run out the air even faster than a breathing apparatus that uses valves.

For reference, a SCBA in 2023 is good for less than 20 minutes.

Oh, and then theres the air conditioning in the space suit, which would be quite a challenge, to keep the astronauts body temperature in a very narrow range.

But keep telling yourself you are a competent engineer LOL
