- logfromblammo 8y agoYou might be able to tow it in from elsewhere using a light sail, however. Beyond our current technology, but might be doable by 2100, or sooner with a fortuitous comet trajectory.
- dotancohen 8y agoAnd once it is in orbit, how do you propose stationkeeping against exospheric drag? Preferably a solution that will remain reliable for 10^n (n>>3) years.
- logfromblammo 8y agoA cubic kilometer of ice is 9.167e11 kg. Also, just keep the orbit above 800km, and the light sail will still be able to counteract its own drag. If the orbit gets too low, turn the ice into rocket fuel and use it to refuel ships boosting into higher orbits.
- dotancohen 8y agoI'm pretty sure that a cubic kilometer of ice in orbit would have more value in other purposes than as a neutrino detector!
- logfromblammo 8y agoSure, but as long as it's up there, might as well use it in every way possible.
