Comment on We really should have all seen this coming.

  ISS is done in (maybe max) 6 years?! We getting a new one for Christmas anytime soon? Gotta be much more… science to do up there that’s inconvenient in a space tent or even a teardrop or something.

  Totally took it for granted.

    Well, yes we’re getting a better one. I worked on Artemis adjacent projects and NASA isn’t just dreaming, they have plans for an actual moon base. It might take a decade or two, but it represents much more sustainable research and more beneficial research than what we have now in the ISS.

    For those interested, I worked as an intern on a few lunar soil related projects and the plan is to actually build stuff with it. If you’re interested, AMA

      You NASA folks just might be used to a challenge here and there:

      Blow my mind with lunar soil in one sentence?

        Not sure what will blow your mind but here’s some fun facts I feel like people don’t commonly know:

        1. Lunar regolith isn’t shallow, in many areas the regolith is 5m deep in the highlands and in craters and other areas it can be as much as 15m deep
        2. The regolith contains agglutinates, particles of rock that have been melted together by meteor impacts. They’re basically rock glass that contributes to the high abrasion of the regolith. We don’t have much of that stuff on earth and it’s very hard to make ourselves.
        3. Due to the lack of atmosphere, much of the dust is charged statically and will cling to astronauts and machines. I knew teams working on a sort of pulsing electricity in a grid of wires to repel the dust off of panels and suits.

  Yeah. I’m not sure how well it’d survive reentry either, but personally, I kinda think broken but repairable is better that fully vaporized.

  Another possibility I considered is welding some steel beams to the outside, vacating the internal atmosphere and then pushing it into a stable orbit; or even pushing it into the moon’s orbit (if it was in the moon’s orbit then you wouldn’t have to worry as much about debris generated by collisions). Then it could sit there until we have the technology to either repair and recommission it, tow it back to earth, or renovate it and turn it into a tourist attraction (yanno, hoping we survive long enough for space tourism to be an actual thing).

  That said, I have no idea if it’d be able to survive deceleration if you tried to put it in the moon’s orbit though. While acceleration could probably be slow and gentle, the deceleration required to keep it in the moon’s orbit might be too much for it.

    Unfortunately the amount of delta-V you’d need to boost it to a parking orbit of some kind, or to the moon, would be deeply impractical. And it doesn’t have the shielding required to support any sort of deep space habitation.

    I’d love to see some or all of it returned to be displayed in a museum, but it would probably be more expensive to do that than it was to build it in the first place. The vehicles to return it in whole or in pieces simply don’t exist right now, and on-orbit disassembly would be incredibly difficult and dangerous for astronauts to carry out.

      I mean, my idea was that it would be effectively mothballed until we have the technology to restore it or something, so the shielding doesn’t really matter. But yeah, the delta-v would probably destroy it. I kinda doubt it could handle it.

      I just found out that the ISS is protected from some cosmic rays by the Earth’s magnetosphere! Hurrah for only getting 90 chest x-rays worth during your stay there, instead of say, 100! Small victories.
