This is a nice mix of the new finding the old. Satellite sensors are being used to find possible sites for further exploration in Egypt. The remote sensing data makes finding the sites easier than more traditional means of digging around. Thus far, dozens of sites have been found that span as far back as 5,000 years ago. While some of this may be going on in other parts of the world already, this is a first for Egypt. It will be interesting to see what these efforts can add to our knowledge of the ancient world.
