SKY ARCHAEOLOGY Eng.sub

Archaeologist Richard Hansen and his team trek through the Guatemalan rainforest while above them a satellite sees through the dense jungle and points the way towards a lost Mayan city.

This jungle holds a secret, a treasure abandoned two thousand years ago. It's a secret unlocked from outer space with a breathtaking new technology. Sensors mounted in satellites and on spacecraft can see what the human eye cannot. Ancient cities hidden under jungle canopies, entire civilizations buried under great dunes of desert sand: this is sky archaeology.
