Sometimes, it takes the very newest technology to find traces of humanity's ancient past.

That's the premise that has guided Sarah Parcak in her career as an archaeologist who relies on remote sensing data gathered by airplanes, satellites and unpiloted drones. Observations from these systems can help scientists tap into visual cues that are invisible on the ground — and in turn, find long-lost traces of humans who lived millennia before we took to the skies.

In her book, Parcak pulls together an impressive collection of discoveries made using these high-tech observations and offers behind-the-scenes stories of her work. The book, "Archaeology From Space" (Henry Holt and Co., 2019), was published in July.

Space.com sat down with Parcak to learn more. This interview has been edited for length and clarity.

And their officers said, 'Wait a minute, you can take pictures from on high?' We take this for granted. But ironically, archaeology started the field of aerial reconnaissance in the military. A lot of people don't know that. Today, we benefit from military technology, so we've shared [technology] over time. But now things are shifting from space-[based] or from air-based platforms to things like UAVs [unmanned aerial vehicles] and drones, because they're much easier to control and they're much less expensive.
