“When a wall is slowly covered over by earth, the materials it's made from decay …” — Sarah Parcak

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.

I predict that there are hundreds of thousands, if not millions, of undiscovered ancient sites across the globe. The only way to map them and locate them quickly is from satellites.

We've got to map all of our ancient history before it's gone because, let's face it, if we don't have a common heritage to share, something to get excited about, then what are we living for?

We have so many issues with overpopulation and urbanization and site looting. And this isn't just Egypt. This is everywhere in the world, even in America. So we only have a limited amount of time left before many archaeological sites all over the world are destroyed.
