Comment Re:expensive clean up (Score 1) 142

surely it would be possible to use existing vehicles and relatively inexpensive thrusters to boost the ISS into some kind of parking orbit which, even if not permanently stable, would keep it aloft for another 15-20 years until we figure out a long-term solution for it?

I agree with others that it's worth an attempt to keep it for historical purposes, but it's also hard to see how spending a billion dollars is the cheapest option.

The ISS is quite heavy. Boosting it would require really a lot of v! You'd either need to run the station thrusters for a *long* time, with probably thousands of refuelings from vehicles that currently don't have the ability to reach it at those higher orbits, or you'd need an external booster with something like 900 *tons* of propellant. You'd also have to worry about it just gradually falling apart mechanically as things wear out from thermal cycling and collisions. But you're right, this proposal is not the cheapest option. The cheapest option would be to do nothing, let it enter uncontrolled, and roll the dice as to where the parts come down.

Another disadvantage: the time when you would most want to tow something else, like an actual trailer or a boat - on a longer trip - you can't, because you're towing part of your car instead. There's also the issue of safety: trailers are terrible for handling and make driving, dangerously lethal as it already is, even more difficult.

There's no inherent reason you *have* to rebuild everything, it's just that our resuable designs are not sufficiently advanced. Early jet engines had to be rebuilt after almost every flight; but after a few decades of refinement, they can operate almost continuously for months without major maintenance.

You're on to something, but I think it's simply a case of chronological proximity bias. The problems we face today always *feel* like the most severe problems ever faced, but that is probably often just because they are the most prominent in our minds. I mean, look how many writers from the last century predicted widespread famine, because when you ran the numbers it just didn't seem possible. They thought it was the biggest problem humanity ever faced. Eventually we managed to overcome it and now it feels like a big nothing. Instead we have our own, new, biggest problems humanity has ever faced. Except they're not, not really. They just seem that way because we know that the other ones got solved, and we don't know yet how to solve the unsolved ones. And those writers, in turn, were probably overestimating the relative severity of that problem compared to other historical problems.

It's the same perspective problem that causes doomsdayism.

The point is that there is nothing that will be preventing you from doing whatever you want to the hardware you bought: hack it, wipe it, blend it, nobody will stop you. What you are actually complaining about is that the hardware you bought isn't exactly the hardware you want. But, it's a lot harder to blame other people for the poor purchasing decision you made.

I don't recall the specific physics principle, but it is something along the lines of 'particles below a certain size cannot be measured without affecting their behavior'.

It's the Heisenberg uncertainty principle. However, by reversing the polarity of the entangled particles and running them through the matrix field of a Heisenberg compensator, you get a controlled tachyon burst that counteracts entropy. At least, that's what I gathered from this write-up.
