I was wondering whether one could bring several asteroids in a regular orbit near Earth and Mars with minimal need for correction. Perhaps there exist orbits which might take significantly longer than a more direct trajectory (e.g. several years), but ultimately it might pay off in terms of reducing radiation exposure.

- QAPereo 9y agoI’m not sure that sweet spot exists, and a lot would depend on composition and entry angle.
- WalterBright 9y agoUsing ice would take a lot less energy to blow it apart on reentry.
- QAPereo 9y agoIce would be ideal for a number of reasons; a shield you could then use for water, air, and fuel! To get a big enough chunk though, you'd probably need to send drones to drag some icebergs from around Saturn. That... would be something! Doable, although probably very expensive, it would share tech with asteroid mining so maybe there's hope for it.
