Dr. Thomas L. Sever is an archaeologist with NASA's Marshall Space Flight Center.Dr. Sever is NASA's only archaeologist and works primarily with Dan Irwin to decode remote sensing readings. While most of his work has dealt with South American and ancient Mayan civilization, Dr. Sever has also used his skills in meteorology.
Remote sensing uses an apparatus that scans the earth with CAMS to detect features not seen by the human eye. While the sensitivity creates hundreds of readings and possibilities, specialists must analyze the data to determine the meanings.
Dr. Sever has found that thermal imaging can discover old routes and footpaths now covered by dense vegetation. By interpreting the data, NASA has located hundreds of old and abandoned cities, not previously known to exist.
Sever also used remote sensing technology in Costa Rica. A project team of professionals from NASA and the University of Colorado searched in the mountains for ancient footpaths, the oldest known in the New World, buried under six volcanic deposits and obscured from the air by a 150-foot jungle canopy. The difference in moisture level of the soils detected by TIMS led to their discovery.Although they saw no physical evidence of the footpaths on the ground, the team dug trenches to confirm their existence through archaeological investigation. In addition, by following the footpaths and using predictive modeling, the project team located approximately 60 settlements and other sites in areas of the Costa Rican mountains that had been believed to be uninhabited in prehistoric times. He currently teaches at the University of Alabama in Huntsville (UAH), his best class is the collapse of civilizations.
Hangar 18 is a 1980 American science fiction action film directed by James L. Conway and written by Ken Pettus from a story by Thomas C. Chapman and Conway. The film stars Darren McGavin, Robert Vaughn, Gary Collins, James Hampton, and Pamela Bellwood.
The stone spheres of Costa Rica are an assortment of over three hundred petrospheres found in Costa Rica, located on the Diquís Delta and on Isla del Caño. Locally, they are also known as bolas de piedra. The spheres are commonly attributed to the extinct Diquis culture and are sometimes referred to as the Diquís Spheres. They are the best-known stone sculptures of the Isthmo-Colombian area. They are thought to have been placed in lines along the approach to the houses of chiefs, but their exact significance remains uncertain.
Aviation archaeology is a recognized sub-discipline within archaeology and underwater archaeology as a whole. It is an activity practiced by both enthusiasts and academics in pursuit of finding, documenting, recovering, and preserving sites important in aviation history. For the most part, these sites are aircraft wrecks and crash sites, but also include structures and facilities related to aviation. It is also known in some circles and depending on the perspective of those involved as aircraft archaeology or aerospace archaeology and has also been described variously as crash hunting, underwater aircraft recovery, wreck chasing, or wreckology.
Gertrude Caton Thompson, was an English archaeologist at a time when participation by women in the discipline was uncommon. Much of her archaeological work was conducted in Egypt. She also went on expeditions in countries like Zimbabwe and South Arabia. Many of her contributions to the field of archaeology include a technique for excavating archaeological sites and information on Paleolithic to Predynastic civilizations in Zimbabwe and Egypt. Caton Thompson held many official positions in organizations such as the Prehistoric Society and the Royal Anthropological Institute.
Guayabo de Turrialba is located near the modern city of Turrialba, within the Central Volcanic Conservation Area in the Cartago Province, Costa Rica. It is almost directly in the center of the country on the Southern slope of the Turrialba Volcano. One can clearly see the volcano because one of the main roads of the site is directly in line with it. Overall, Guayabo covers about 540 acres and is surrounded by rainforest plant vegetation causing it to be extremely vibrant green due to high precipitation and rich soils. One of the most unique facts about the site is that only a small portion of it has been unearthed, excavated, and studied.
The causes and degree of Olmec influences on Mesoamerican cultures has been a subject of debate over many decades. Although the Olmecs are considered to be perhaps the earliest Mesoamerican civilization, there are questions concerning how and how much the Olmecs influenced cultures outside the Olmec heartland. This debate is succinctly, if simplistically, framed by the title of a 2005 The New York Times article: “Mother Culture, or Only a Sister?”.
Sarah Helen Parcak is an American archaeologist, Egyptologist, and remote sensing expert, who has used satellite imaging to identify potential archaeological sites in Egypt, Rome, and elsewhere in the former Roman Empire.

As of February 2015, Saturno holds a position as assistant professor in Archaeology at Boston University's (BU's) College of Arts and Sciences (CAS). He is also the director of the Proyecto San Bartolo-Xultun at the Instito de Antropologia e Historia in Guatemala, a national space research scientist at the Marshall Space Flight Center, as well as a research associate at the Peabody Museum at Harvard University. Prior to his position at BU, Saturno was a lecturer at the University of New Hampshire.
Archaeology, or archeology, is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. In Europe it is often viewed as either a discipline in its own right or a sub-field of other disciplines, while in North America archaeology is a sub-field of anthropology.
Remote sensing techniques in archaeology are an increasingly important component of the technical and methodological tool set available in archaeological research. The use of remote sensing techniques allows archaeologists to uncover unique data that is unobtainable using traditional archaeological excavation techniques.
Holmul is a pre-Columbian archaeological site of the Maya civilization located in the northeastern Petén Basin region in Guatemala near the modern-day border with Belize.
Las Mercedes (L-289-LM) is a complex archaeological site located on the Caribbean slope of Costa Rica between the foothills of Turrialba Volcano and the alluvial plain. The site contains a variety of architectural features including platforms, plazas, retaining walls or terraces, funerary areas, ramps, and paved roads.
The Arenal Prehistory Project was a multidisciplinary research effort taking place between 1984 and 1987 that uncovered evidence of human occupation from Paleoindian and Archaic times through four sedentary phases to the Spanish Conquest in the tropical rainforest of Northwest Costa Rica.
Samuel Kirkland Lothrop was an American archaeologist and anthropologist who specialized in Central and South American Studies. His two-volume 1926 work Pottery of Costa Rica and Nicaragua is regarded as a pioneering study. Lothrop was a longtime research associate of Harvard's Peabody Museum of Archaeology and Ethnology and made many contributions based on fieldwork, laboratory analysis, and evaluations of private and public collections that focused on Central and South America. He is known for archaeological excavations in Argentina and Chile as well as investigations of the archaeological contexts for the stone spheres of Costa Rica. Lothrop is also known for his research on goldwork and other artifacts from Costa Rica, the Veraguas Province of Panama, and the Sacred Cenote at Chichen Itza, Mexico.
Michael Jay Snarskis was an archeologist from the United States who founded the scientific study of archaeology in Costa Rica. At that time, almost all artifacts available to collectors were shorn of their provenance and historical significance by huaquero looters, whom Snarskis described as "the tomb-robbers ... who have [made] such studies more difficult."
Atlantis of the Sands is the fictional name of a legendary lost city in the southern Arabian sands, claimed to have been destroyed by a natural disaster or as a punishment by God. The search for it was popularised by the 1992 book Atlantis of the Sands – The Search for the Lost City of Ubar by Ranulph Fiennes. Various names have been given to this city, the most common being Ubar, Wabar and Iram.

Arlen F. Chase is a Mesoamerican archaeologist and is faculty member in the anthropology department at the University of Nevada, Las Vegas. Previously, he served as the Departmental Chair at the University of Central Florida, noted for his work on exploring traces of Mayan civilization using lidar.
La Ciudad Blanca is a legendary settlement said to be located in the Mosquitia region of the Gracias a Dios Department in eastern Honduras. This extensive area of rainforest, which includes the Río Plátano Biosphere Reserve, has long been the subject of multidisciplinary research. Archaeologists refer to it as being a part of the Isthmo-Colombian Area of the Americas, one in which the predominant indigenous languages included those in the Chibchan and Misumalpan families. Due to the many variants of the story in the region, most professional archaeologists doubt it refers to any one actual settlement, much less one representing a city of the Pre-Columbian era.
