Sarah Parcak uses satellites orbiting hundreds of miles above Earth to uncover hidden ancient treasures buried beneath our feet. There's a lot to discover; in the Egyptian Delta alone, Parcak estimates we've excavated less than a thousandth of one percent of what's out there. Now, with the 2016 TED Prize and an infectious enthusiasm for archaeology, she's developed an online platform called GlobalXplorer that enables anyone with an internet connection to discover unknown sites and protect what remains of our shared human inheritance.
