太空考古

太空考古学是利用高分辨率卫星影像和激光技术发现、测绘地下考古遗址的新兴领域。TED研究员萨拉·帕尔卡克深耕这一领域，借助卫星遥感在埃及等地发现了大量隐藏遗址，并指出我们对古埃及的认知目前仍只是冰山一角，未来25年将迎来全面突破。

Ancient Peru was home to many cultures, most of them still mysterious. But as Sarah Parcak points her satellite-archaeology lens (and her new citizen-explorer project) at the Peruvian wilderness, the invisible past is primed to make a remarkable comeback.
