Wonder of Science

A short compilation of astronauts falling over on the Moon during the Apollo missions, showcasing their challenges with balance and movement caused by the Moon's low gravity, bulky spacesuits, and navigating the loose, dry lunar regolith.

@wonderofscience The tiniest pinhole and they would be dead.

@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! 😂 😁

So slapstick has gone farther than capitalism.
That's a good sign.

This needs a soundtrack.
Something like a slow version of Yakkety Sax

@wonderofscience I need this set to Benny Hill music or something goofy, lol.

GhostOnTheHalfShell

@wonderofscience It's funny how they look like they have springs

@wonderofscience
Great recovery by one of those astronauts.

Imagine tripping, reacting as you normally would, but the ground isn't as close as it should be because you're falling slowly. Apollo astronauts probably felt like toddlers taking their first steps.

@wonderofscience So how did they do this on a soundstage on Earth?🙄🤪😛🤣🤣🤣

@RebeccaBoyce @wonderofscience This is one for you flat earthers- you can’t believe the evidence of your own eyes! So, you invent another conspiracy… #ufo #uap #moon

🔥torstein🔥

@RebeccaBoyce @wonderofscience According to the Corridor Crew (a VFX channel on YouTube) these "blooper" videos are clearest evidence for the Moon landing being real, because the technologies (camera mechanics, image manipulation) needed to make these shots didn't exist for several decades after the landings.

@wonderofscience henceforth, I will refer to those bare patches in the backyard as the regolith.

No officer, I haven't been drinking. It's just the gravity.

@wonderofscience Pratfalls in space.

Buster Keaton would've been a natural.

Michael Cormido

@wonderofscience it’s crazy they aren’t more careful with falls like these… something could puncture the suit, damage some important equipment, etc.. I’m the caring parent 😂

Aunty Miche🛡🇺🇦

@mikecormido @wonderofscience They were designed so the chances of that were very low. There's a comment upthread that goes into detail.

apgarcia

@wonderofscience too bad break dancing hadn't been invented yet..

Timotei

@wonderofscience More proof that the moon-landing wasn't faked.

Patty Kimura

@wonderofscience

Sorry, NASA spacemen, but this was funny.

You can also see why collapsable carts and bungee cords were invented.

Zero gravity is, however, a great excuse I will try when I trip over my own feet.

TransitBiker

@wonderofscience The reason for the outer bulky space suits, is to protect the inner suit from rocks and stuff. Probably did not help that their boots had a very basic tread.

Nick ✅

@wonderofscience But why didn't the director just yell "cut!" and have them re-film the scenes without tripping? Surely the studio execs would want it to look convincing!

Scorpil 🇺🇦🇪🇺

@wonderofscience I wonder, could they even roll over if they fall back?..

Aunty Miche🛡🇺🇦

@scorpil @wonderofscience They always went outside in pairs. Their buddy would help them up.

Dieses Video nutze ich gerne im #Physik #Unterricht um die Gewichtskraft auf dem Mond zu erklären. Der Rucksack der Astronauten wiegt etwa 80 kg. Zur Veranschaulichung sollen sich die SuS vorstellen, sie müssten ihren Vater Huckepack nehmen und dann springen.

Selbst in der Mittelstufe werden die SuS plötzlich ernst, wenn der Astronaut berichtet, dass aus Spaß Ernst wurde und er plötzlich Todesangst verspürte…

@wonderofscience That's me after a few beers, although I am not sure my knees could take that hammering now!

@wonderofscience These videos are what finally convinced me that the Moon Landing was real.

@wonderofscience Michael Jackson was too graceful. "Ooh ooh ooh!" should have been "Oops oops oops!"

@wonderofscience guess I'll just have to hum the Benny Hill Theme to myself...

@wonderofscience Not to mention the secret dehydrated vodka in the Tang.

@wonderofscience
Wow.
I'm really glad their suits were high-spec. Money well spent!

Some of them are like: "Hey I have less weight, less weight!! Ohhh, oops still got the same momentum................" FLOPCRASH

@wonderofscience I wonder if they ever felt like if they bounced too high, they wouldn't come back down.

@wonderofscience We have a saying in roller derby: Falling is learning.

It applies here too.

It doesn't matter how many times you fall down. It's how many times you get up.

@wonderofscience I love the one where they fall forward, then just sproing back up :zerotwo_excited:​

@wonderofscience It's a dirt trampoline! One of the recoveries is a thing of beauty.
