To excavate a pyramid is the dream of every archaeologist.

My dream is to map every archaeological site in the world because, if we can do that, then we have this massive global data base that all sorts of global heritage organizations and heritage organizations within countries can use, and they can use that information to protect what's there.

I'm looking at looting photos from space, and there are people putting their lives on the line every day protecting their heritage. I call these people the real culture heroes.

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've found numerous things - settlements, temples, possible pyramids, forts, roads - the list goes on and on. I'm not as interested in the discoveries as the types of questions they help us formulate.

It's both Indiana Jones and 'National Geographic' that inspired me to be an Egyptologist.
