You're at a time frame where you have to worry about subduction. There's areas of the ocean floor that are candidates, but I'd seriously consider a high orbit or lunar placement if you're going for that time period. Also saves a lot of environmental challenges.
- JoeAltmaier 5y agoThat's true. I suspect the major risk in such a timeframe isn't tectonics, corrosion or environmental weathering. It's likely 'human interference'. Maybe a million-year orbit? So it's safely out of range of meddling for the duration.
