    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.

    • @PiDsPagePrototypes
      @PiDsPagePrototypes 7 годин тому

      What would be best, is if modules could be retrieved in the new Heavy Lift vehicle, like Starship, and brought back to be sent out to national museums for their country of origin, and then de-orbit the frame work structures that are keeping those modules running.
      As Patrick commented above, it's been through so many heating and cooling cycles, that it's fatigued to the point where it needs replacing.
      The only orbit that would keep the whole ISS intact is one where it remains at a constant temperature, either in the sunlight or in the shade. In the light, it eventually over heats unless it's moved further out away from the Sun, in the shade it quickly freezes and cracks.

    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

    • @UncleKennysPlace
      @UncleKennysPlace 5 днів тому +2

      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.

    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.

      That sounds like it was the second test-to-fail unit, where they vastly exceeded the expected fail points, so the pressure achieved was much higher, with a inside to outside ratio of close to 7:1, compared to this tests 4:1 (remembering that it's 1:1 at around 15psi, because of the outside air.)

      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!

      White works better for heat rejection - the materials used to make the white coatings are mirror-reflective at Infra Red frequencies.
      When they hit Four times atmospheric pressure inside, that's effectively the same loading as Three times inside when in space. The latest version has gone higher again before failure.

    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.

    Sierra are really taking the NASA TRANSHab and Bigelows B.E.A.M technology and doing amazing work with it. The size these modules will be able to reach when flown on the new Heavy Lift class of rockets being developed by SpaceX and Blue Origin, will be like launching Apartment Buildings in to space, giving much more useable volume for sciences, engineering, and living, for those working there.

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.🌸

    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.

    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?

    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...

      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.
