Our guest is the Yale- and Cambridge-trained space archaeologist, Egyptologist, and satellite-imagery pioneer, Sarah Parcak. She's known for employing infrared imaging -- i.e., hi-tech images captured by a satellite orbiting the Earth -- in order to locate thousands of undiscovered archaeological sites worldwide. Dr. Parcak is also known for developing the ongoing GlobalXplorer project, which is an online community whereby "citizen scientists" can assist in the search for lost civilizations. She'll be speaking soon here in Tulsa at the Cascia Hall Performing Arts Center; it's a Tulsa Town Hall evening event scheduled for April 11th at 7pm. (Tickets and more details are here.)
