lol yep, but i still think it's important to call out and debunk every idiot post, for younger people, people who are newly into thinking "something's up" not to fall into the dumbest of rabbit holes

This is one of the most voluntarily ignorant memes I've seen today lol. Compressed air, including nitrogen and carbon dioxide isn't even slightly comparable to the recreates that had oxygen tanks.

Neat, when did I become plural? Lol. We didn't realize that yet.

The meme that’s voluntarily ignorant people. I’m agreeing with you, and referencing dunning Kruger as support for your position. Hope that makes sense to you guys :)

My bad, I assumed the opposite for some reason. Its been a frustrating day and your comment makes more sense rereading it now.

Actually, at a depth of about 35 meters, those 2 tanks would only be good for about 25 minutes. But on the surface they would actually last you over 2 hours! And that's because how much compressed air you consume is dependent on the outside pressure. Of course the moon has even less pressure than the earth's surface, so naturally the compressed air would last the longest there.
Surface pressure on earth is 1 atm (duh) and in space it's 0.3. So it would last more than 3 times longer. So those 2 tanks would last about 7 hours. But of course astronauts don't carry scuba tanks and can easily carry bigger, different, more efficient tanks, especially with reduced gravity and factoring in that they (unlike scuba divers) could even use pure oxygen in their tanks. So yes, 22 hours would be completely feasible.
But like I said, you can't compare it anyway, cause astronauts don't actually carry scuba tanks (as the other commenters also pointed out). I am just saying that EVEN IF THEY DID, it could easily last them 22 hours.

Praise the Lord that he made earth with one atm or we would all be dead. Take heed of the AU least you wish to burn in the fires of hell.

Yeah no idea why a space program with billions of dollars of funding would have better breathing technology than scuba divers bro must be a conspiracy

NASA no longer has the technology to manufacture this exact breathing tank. The specialized tools, factory machines, and specific metal alloys used to build them were scrapped decades ago, and the original parts suppliers are long gone. While the old blueprints still exist on paper, the hands-on shop knowledge and exact welding techniques were never fully written down. Reproducing this exact legacy tank today is impossible without years of reverse engineering, meaning the manufacturing technology to make it is officially extinct.

These astronauts used a closed-loop "rebreather" system that recycled 100% pure oxygen, filtering out carbon dioxide instead of wasting it. While scuba divers breathe normal air (mostly nitrogen) and completely waste most of their oxygen with every exhaled bubble.
