- QAPereo 9y agoI’m not sure that sweet spot exists, and a lot would depend on composition and entry angle.

- 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.
