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. Sarah Parcak analysisbenefitchange share on social
When I was a child growing up in Maine, one of my favorite things to do was to look for sand dollars on the seashores of Maine, because my parents told me it would bring me luck. But you know, these shells, they're hard to find. They're covered in sand. They're difficult to see. Sarah Parcak bringchildcover share on social
What satellites help to show us is we've actually only found a fraction of a percent of ancient settlements and sites all over the world... It's the most exciting time in history to be an archaeologist. Sarah Parcak ancientarchaeologistexcit share on social
Archaeologists have used aerial photographs to map archaeological sites since the 1920s, while the use of infrared photography started in the 1960s, and satellite imagery was first used in the 1970s. Sarah Parcak 1920s1960s1970s Change image and share on social
That's what I want to do, ultimately: figure out a way to get the world engaged with discovery and protecting these ancient sites. Sarah Parcak ancientdiscoveryengage Change image and share on social
The only technology that can 'see' beneath the ground is radar imagery. But satellite imagery also allows scientists to map short- and long-term changes to the Earth's surface. Buried archaeological remains affect the overlying vegetation, soils and even water in different ways, depending on the landscapes you're examining.

Before doing fieldwork in Middle Egypt, I analyzed satellite imagery to determine exactly where I wanted to go. Within three weeks, I found about 70 sites. If I had approached this as a traditional foot survey, it would have taken me three and a half years. Sarah Parcak analyzeapproachdetermine share on social
Satellite datasets like WorldView can see objects as small as 1.5 feet in diameter. In 2014, WorldView-3 will be able to see objects a small as a foot. Sarah Parcak datasetdiameterfoot Change image and share on social
We want to excite the world about what's out there. But we don't want them to say, 'Oh, there are lots of sites in Egypt - let's loot.' Sarah Parcak egyptexciteloot Change image and share on social
WorldView-3 goes into the mid-infrared wavelength, allowing you to see very subtle geological differences on the sites at a 0.4-metre resolution. Sarah Parcak allowdifferencegeological Change image and share on social
