Some small corrections:
1: the astronauts did not use the OPS while disposing of the PLSS. Rather, they were tethered to an oxygen supply within the LEM while they disposed of the PLSS portion of the backpack.
2: diving suits do not maintain a standard sea level pressure. They are kept relatively close to the pressure of the depth that they are used at.

No the reason they bunny hopped on the moon was to try to appease the moon rabbits who were less than thrilled about their intrusion

I like the stripes being named “public affairs stripes.” I can just imagine an engineer with no interest in aesthetics coming up with that name

I need to binge watch moon footage. The way they talk is so funny. “That ain’t any fun, is it?” when your buddy almost dies lmao

Early suits go hard. They look so cool, especially knowing how cutting edge they were

56:54 "Italian astronaut was caught boiling pasta in his space suit"

So fun fact!
My Grandfather helped United Technologies as a senior project engineer on the equipment used on space suits!!
If memory serves right he worked on the rings for supplying oxygen, and water for cooling.

I don’t care if it was a tiny piece, or the whole suit.
He was a part of history.

Thank you for reminding your viewers that "The Everyday Astronaut" tried to earn himself a Darwin award.

Charlie Duke once said in an interview that the moment he fell over was the only time during the Apollo 16 were he was afraid

Best quote: "early spaceflight was truly the stuff of nightmares" . I think few people realize what "The right stuff" really means....to not panic and the ability to control your fear being a big part of it.  Just the shear claustrophobic conditions alone would freak me out, let alone having to sort out a life or death problem while cramped inside a tiny tin can.

21:50 Seeing Gura in this video was one of the last things I could have expected 😂

Regarding diving suits versus space suits:

Diving suits require the same internal volume as pressure outside changes to hundreds of atmospheres.

A spacesuit only requires a difference of at most two atmospheres. Since breathing is the only requirement and we breathe 20% O2 at 1atm you could theoretically get away with just 0.2atm at 100% O2. This was done in early designs of space capsules but cancelled after a certain fire.

A leak in a high depth diving suit will instantly kill whoever is inside, the water will expand inwards at the speed of sound of the medium (1400m/s) and the mass flow rate is determined by the pressure (per 10 meters of depth ~+1atm of pressure) This combination is a guaranteed millisecond death.

A leak in a spacesuit will move at a glacial 340m/s and a pressure of 1atm.

note that these are rough calculations, obviously the diving suit wouldn't kill you at low depth and the spacesuit requires additional isothermic protection.

By the way the smallest spacecraft was the vostok, it was infact so small they specifically hand picked cosmonauts under a certain height just so they could fit inside the craft

1:06:16 A note about the suit from The Martian - it looks to me like it was inspired heavily by the MIT BioSuit, which uses a very tight fabric to provide mechanical pressure instead of air (i remember watching a documentary when i was younger where mike massimino got to wear one and said that he "felt like an italian sausage", although i dont remember which one it was.) Im guessing that the actual mechanical pressure layer is worn on the inside, with an outer layer that houses some kind of temperature control system which would explain why it doesnt look super tight in the movie. The vacuum EVA suits are much bulkier and basically just look like the EMU suit with some extra hinges for better mobility.

21:42 They went to the trouble of spray painting 2 pairs of boots, but they couldn't put the guys without boots in the back so their feet weren't visible in the first place???

14:31 that's a British Boys anti tank rifle, .55 caliber, and that drawing is badass as hell

12:43 This feels like an album cover

I don’t understand why you don’t have millions of views on your videos. The quality of your work is as good or even better as any other content provider on YouTube or any streaming channel. I’m glad you have advertisers; you deserve it for your hard work. Great video by the way.

1:07:29 Thanks to you for commissioning me, it was fun making the drawing of the gooba ;D

Arthur C. Clarke had a fairly close prediction of space suits as he knew our legs would be a major struggle in space. He described an EVA suit that's basically a dive suit again, but with the waist down in an enclosure.
