So awesome! I’d love to see a test where they shoot the module with different firearm rounds to demonstrate its real resilience against micro-meteorite impacts.
I live in the city where they are testing these things. We have an arsenal where they literally test bombs and detonate expired ordinances. So, we hear booms basically every single day. But when they blow these things up, it is way more intense. It literally shook houses miles away. For some reason they tested one on October 29th at around 9:30 or 10 p.m. and woke up basically half of North Alabama.
I'm surprised the engineers didn't include a layer with a self-hardening chemical mix to improve the habitat's rigidity after inflation. I'm also bemused about why they favored a catastrophic failure mechanism over a progressive one with the same ultimate pressure as a progressive mechanism would not only enhance safety for the inhabitants but also prevent explosive disassembly in the event of a puncture
No need, as any internal pressure will help it keep its shape. The extra mass would be no so good. In terms of failure mechanism, most actual failures would likely be progressive. But building that in would require essentially building in weakness.
They do longer tests as well. They just don't make as cool a vid. As for some chemical process that happens post-deployment, that sounds like a huge pain.
Rigid structures have there own drawbacks like stress and material fatigue. Over pressure valves are common enough to prevent ever reaching failure point...
Looks like Bigelow Aerospace sold their rights to the inflatable space station. Bigelow Aerospace version was called the BEAM short for bigelow expandable activity module. I know this because I’ve worked on it in Las Vegas.
The ISS should be put into a higher orbit, and maintained as a museum. As technology improves, launch and operations costs decrease, the ISS should be moved into a higher, stable orbit, where it can await, for maintenance and use.
Unfortunately, it's not that simple. If it's not taken down, it will fall apart and become a hazard. The pressure vessels (and the joining seals) have gone through countless hot and cold cycles, etc. It is at the end of it's life.
Actually, probably still 77. Typically, when you're measuring pressure in the atmosphere, it's already accounting for atmospheric pressure, so you're just measuring the difference. So it's likely that they inflated it to the absolute pressure of 91.7 psia, which would read as 77 psig. In space, it would fail still at 77 psia.
Right, right. Also, there's no outside atmospheric pressure in space that presses against the habitat from all sides. Wow! That's some crazy level material engineering! You could use maintenance bots in space that slowly paint aluminum on the outside to reinforce the inflatable for prolonged usages.
I would think the next step instead of trying to blow it up is to have it hold at 60 PSI for 48 hours without leaking. Just a pressure test to hold it cuz even though it holds at 15 psi it can still have a small leak somewhere.
11:02 I wonder how large of a micrometeorite that skin could withstand. Generally you want multiple layers of protection rather than a single thick skin. With using an inflatable bubble I would expect that a single hole would compromise the rest of the bubble's ability to hold its shape rather quickly. Patching it wouldn't necessarily be that bad if you got it patched within a minute or so (see The Expanse)... Getting to that layer through the 7 other sealed layers around it though.... How would you even start?
If you're testing at 15 PSI outside and only 65 psi inside, correct me if I'm wrong... That is in a 4X safety factor, in order to do a 4X safety factor you would have to multiply 15 PSI * 5 so you would be at 75 PSI for a burst test. And since it's a pressure vessel, shouldn't you be testing it with liquid internally instead of air? I was routinely testing pressure vessels and we always had to test with liquid not air.
Great innovation. What would happen if the bag was tripled bagged then aired up. Will this increase more pressure. Would love to see more testing on this subject. In theory more layers the better. Triple the mass of everything ignore the weight and go for a bigger test. If successful then the team and company can make it more possible for the future.
@Amsterdampardoc1 It's not so much the parts as the materials that they are composed of. Better to salvage what is already there to be recovered for use again. No sense wasting all that gold, copper, platinum, etc. burning up on re-entry. Every penny counts.
Definitely going in the right direction. I'll be really impressed when the can make it a mile diameter. Not verry thick walled for all the features considered so there's room for reinforcement like a "retread". Spin it to 1.5 g and be naturally buff.😁
Gently placing to the side my passion for watching researchers safely blow things up, I am heartened by the new ideas which will be used for building habitats in space. Looking forward to NASA weening off of SpaceX as NASA moves towards supporting/enlisting the help of space organizations which do not harbour hate and anti-science enablers (e.g., Elon Musk types). Please, do not get me wrong. The people working for Elon are incredible. It is that they their work and ideas are benefitting a harmful and unfit member of our species. Say no to owning a Tesla and say no to relying on SpaceX for any of our of international space goals and explorations. Say yes to keeping space a place for our humanity and not for our weaknesses, e.g., hate, corruption, and psychopathies, just to name a few.🌸
Is also annoying generally. This is not a music video. There have been a few videos where for some strange reason the video creators chose music which had about the same beat as the person's voice & it greatly interfered with understanding the speakers.
Former Boeing... this new type of habitat has many advantages over former habitats. I am all for a new International Space Station... however I am not in favor of returning to the Moon or sending humans to Mars. We've been to the Moon numerous times and there is no reason to go to Mars in person. We already have probes on the surfaces and satellites overhead. We know more about the Moon and Mars than we do our own deep oceans. Let's replace ISS and map our own planet including deep oceans. If anyone has a valid reason to go back to Moon or send people to Mars please let me know. I have 3 advanced degrees and decades of experience... I was the biggest supporter of NASA and was around when Sputnik was launched and when men walked on the Moon. Don't give me 'trickle down technology' that was pushed for decades. ROI is only about 1:100. Money is better spent on directly funding R / D here on Earth. Cheers...
need the uk versions, also hate the repetition of information on u.s. media. repeat everything twice by default. mars cant hold an oxygen rich atmosphere due to its low gravity. its a dead end mining colony. venus on the other hand can be easily tweaked to be more earthllike, has all the ingridients.
Use the same methods used for the balloons which get used as spacesuits. For one reference, look up Cosmo BC astroblog of March 13, 2010, about inflatable space stations. It mention's Bigelow's testing which showed that at least some particles which would puncture a rigid metal structure would end up bouncing off a resilient inflatable structure. 🛰 In addition, it is expected that these inflatable habitats can borrow the concept of self-sealing fuel tanks like military aircraft have used since the previous century. 🛰 Plus, NASA and others hold patents for things such as the "Multi-Layered Self-Healing Material System For Impact Mitigation, LAR-TOPS-122". 🛰 And I'll bet the concept was being looked at as far back as 1961 when NASA commissioned Goodyear to build a 30 foot diameter prototype of a ring shaped inflatable space station, but only here on the ground. Mostly what I remember of that one is the astronauts found the interior fragrance of 'old tire' objectionable.
I once saw a building being demolished with a wrecking ball. I thought, it's a good thing they're tearing it down, if it can't even stand up to a wrecking ball.
Human bodies will never inhabitate another planet or space, maybe Mars for brief stints. Human bodies are too fragile and temporary. Ithinks it's great to explore the universe to better understand and improve Earth's existence.
Please please take a page from spaceX’s playbook. Just get one of these in space and test it for real and stop bullshiting. You have been in development since 2018. C’mon! Development’s of new tech shouldn’t be taking 1/2 a decade.
Love your videos, NOVA!
This looks like something you'd see at a space trailer park in the distant future...
Space hobo tents will come with a roll of duct tape, for the micro meteorites zipping thru.
Yurts in space. It was bound to happen. Good design has no expiration.
Hippie encampments
Imagine the unregulated beer bottles, junked spacecraft, and poop...
Mom, to kids in space... "Close the damn door!! You're letting the space in!"
And dark matter.....racist....haha
That's not how it works.
So awesome! I’d love to see a test where they shoot the module with different firearm rounds to demonstrate its real resilience against micro-meteorite impacts.
Agreed. Its more realistic the issue is space projectiles.

I was wondering about that. I was also concerned for animals😢

That burst at 77 psi on earth with 15 psi pushing on it from the outside. What would the burst pressure be in the vacuum of space
Just subtract. 77-15=62 psi
Actually, probably still 77. Typically, when you're measuring pressure in the atmosphere, it's already accounting for atmospheric pressure, so you're just measuring the difference. So it's likely that they inflated it to the absolute pressure of 91.7 psia, which would read as 77 psig. In space, it would fail still at 77 psia.
@@tarktari Bingo!
Yeah, i feel they are trying to say 77 psi difference from inner/outer
@@tarktari This
Right, right. Also, there's no outside atmospheric pressure in space that presses against the habitat from all sides. Wow! That's some crazy level material engineering!

@11:00 use 1/4 Speed!
This is great but living beyond earth's magnitosphe is still a problem due to cosmic radiation.
I would think the next step instead of trying to blow it up is to have it hold at 60 PSI for 48 hours without leaking. Just a pressure test to hold it cuz even though it holds at 15 psi it can still have a small leak somewhere.

How would you even start?
Double or triple layer with thin ice layer so csn recoverable and cooling also use air pressure to push fast maneuver avoid missile or debris
That was great!
I had no idea they are devellopping this.
Honestly, the Habitat looks like a giant HomePod.

How are they going to insulate from high energy particals ?
Didn’t know “explode” was a way to get to somewhere.
Elon musk has already captured the lucrative space screen door and window market.
10:42 - if you just want to skip the blah, blah, blah...
You know what that means?
No beans and cornbread in space 😅

Would these work underwater?
I won't be waving my hand to be part of the first space launch (or the second.) 😳
'basket Weave design' 😂 the aliens t laughing at us right now
Why de-orbit ISS? Leave it in orbit and salvage its parts during the life of the next ISS.
The parts were designed and made ages ago, also stuff is breaking down frequently. The parts wouldn’t be useful later.
@Amsterdampardoc1 It's not so much the parts as the materials that they are composed of. Better to salvage what is already there to be recovered for use again. No sense wasting all that gold, copper, platinum, etc. burning up on re-entry. Every penny counts.
Obsolescence.

Soooooo uh next test explosion in orbit? That's gonna be soooo kewl. Where does oxygen go in the vacuum of outer space!

:) Interesting idea; having special work out space stations at spinning gravities above 1.0 . And old people living in stations below 1.0
It looks just like my flat in England.

I didn't realize that it takes so many people to blow up a balloon. 😅
Legend has it that if you cross the ozone layer... You will burn in minutes which eventually leads to boiling to death 💀
Well, legend trumps science any day.
@falcychead8198 sorry i don't understand your point of opinion🙄
Nice! A little mythbusteresque. Keep up the habitatin'!
Why do you have this ridiculous music competing with what's being said and ruining what could have been an interesting video ?
Before thinking about building safe housing on Mars shouldn’t we first solve the homelessness crisis on Earth?
No, send them to mars, they're the perfect guinea pigs
No music behind the commentary please. It’s annoying for people with anxiety. ❤

But 77psi isn't a lot.
A repost dajvew
Balloons in space is a hard no for me. Thanks.😊
I absolutely would not approve a habitat that catastrophically fails like that 😬 i would rather see a gradual failure...
The failure of a metal tube in space would be from a puncture or an explosive incident - the same as with this fabric enclosure.
I once saw a building being demolished with a wrecking ball. I thought, it's a good thing they're tearing it down, if it can't even stand up to a wrecking ball.
🤔Nice, but with the recent "junk", asteroid movement, magnetic crap and UFO stuff happening better make sure its armored and carrying shovels.😊😅😂

After you listen to SpaceX development, these things feels like a high school project. Nothing seriously. Ana I have a feeling, this will not go far.
As long as you have Sean Buckley leading the team, this project will never succeeded. Ask him about the beam.
Yeah, ya proved it in front of a green screen in a film studio harnessed to suspension cables lol.. tf outa here
