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.

It takes minutes to play, but 'Unmanned' sticks with you for long after the credits roll.
