Space Station To Be Deorbited After 2020

astroengine writes "Russia and its partners plan to plunge the International Space Station (ISS) into the ocean at the end of its life cycle after 2020 so as not to leave space junk, the space agency said on Wednesday. 'After it completes its existence, we will be forced to sink the ISS. It cannot be left in orbit, it's too complex, too heavy an object, it can leave behind lots of rubbish,' said deputy head of Roskosmos space agency Vitaly Davydov."

    Yes it would take a lot of energy to get to the moon's orbit and yes you'd need to expend some more to put it into orbit AROUND the moon. If you made judicious use of the "interplanetary expressway" (I think that's what it's called), you could use the chaotic nature of orbits to trade time for energy but you're still going to need a good deal of delta-V.

    So why not hook up an ion engine?

    Nobody will be living on the thing (it has to go through the Van Allen radiation belts) so all the power for life support from those huge solar arrays will be available. Use this power to hook up an ion engine (with a relatively modest amount of xenon fuel) and a slow spiraling orbit could take you out of LEO to almost anywhere. I'd prefer L1 because the views would be so nice but given a bit more fuel (and a lot more time) you could put it next to, say an asteroid where it could be a really useful base for scientific studies (how about the one that might clock us in 2036?).

    In fact, if put into the proper position (relative to the sun) BEHIND the asteroid (very easy due to the negligible gravity) the asteroid will block out any danger from lethal solar flares! (Of course any manned mission to an asteroid should think about using this trick, might be a lot easier than digging into the soil/pebbles/hard rock/baked lava of the asteroid's surface.

    NASA's been doing a good job of repurposing old spacecraft for new missions once they've completed their primary mission (like Deep Impact which went on to some more comets or Artemis which is now headed to the moon I think). Why not a whole space station?

    By the way, does anyone know if (now that the space shuttle doesn't go there anymore) it can be boosted to a much higher orbit? (the space shuttle barely had enough fuel to reach it). I believe Soyuz, Falcon 9/Dragon and the European resupply ship can go considerably higher.

    That's only true if you're comparing a trip from the earth surface to LEO, to a trip from earth surface to lunar orbit. And then the reason why it's exponentially more expensive is because everything you're planning on sending from LEO to the moon also has to be lifted to LEO, and whatever you're using to lift that has to be lifted, etc.

    That's why the Saturn-V had to be so huge while the return vessel could be so small -- the return vessel got to do the LEO to earth surface transition for "free".

    But if you're going to lunar transfer from LEO, then you're already most of the way there! In fact, once you're in LEO, then you're almost halfway to Mars. And I don't mean Mars orbit; I meant the surface.

    From Ye Olde WP, Delta-v for:
    Earth surface to LEO: 9.3-10 km/s
    Delta-v for LEO to LL(unar)O: 4.8
    Delta-v for LEO to LM(ars)O: 6.1
    Delta-v for LMO to Mars surface: 4.1

    This is why Saturn-V, Constellation, and other ultra-heavy lift vehicles intended to be used to lift things from earth to some destination beyond LEO make no sense -- for the future, that is. It made sense for Apollo because they didn't want to spend the time developing infrastructure in LEO for a two-step mission.

    But that's what we should be doing. When we think of going anywhere beyond high earth orbit, we should be thinking of it as two distinct steps: Earth to LEO, and the LEO to the rest of the solar system. If you can use cheap and efficient commercial lift vehicles to launch pieces of the inter-planetary mission into LEO, assemble and refuel it there, then you can have vastly expanded missions at vastly reduced prices.

    That's part of what NASA's new plan involves, if it survives Congress. And it sounds like the Russians are planning to do this with their parts of the ISS.
