What satellites help to show us is we've actually only found a fraction of a percent of ancient settlements and sites all over the world... It's the most exciting time in history to be an archaeologist.

Scientists use satellites to track weather, map ice sheet melting, detect diseases, show ecosystem change... the list goes on and on. I think nearly every scientific field benefits or could benefit from satellite imagery analysis.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
