NASA archaeologist Dr. Tom Sever explores the Guatemalan jungle, which hides the ruins of one of the world’s oldest and most mysterious civilizations — the Maya. Sever and his partners, archaeologist Dr. William Saturno of the University of New Hampshire in Durham, and researcher Daniel Irwin of NASA’s Marshall Space Flight Center in Huntsville, Ala., are using advanced imaging technology developed for the space program to uncover the ruins. High-resolution satellite imaging, which detects variations in the color of plant life around the ruins, has enabled the researchers to pinpoint the sites of several Maya settlements from space — before taking a single step into the jungle. The research, primarily conducted at the National Space Science and Technology Center in Huntsville and the University of New Hampshire, is made possible by a partnership between NASA and the Guatemalan Institute of Anthropology and History.
