Extractions: made to orbit the Earth. Gravity is such an accepted part of our lives that we rarely think about it even though it affects everything we do. Any time we drop or throw something and watch it fall to the ground, we see gravity in action. Although gravity is a universal force, there are times when it is not desirable to conduct scientific research under its full influence. In these cases, scientists perform their experiments in microgravity - a condition in which the effects of gravity are greatly reduced, sometimes described as "weightlessness." Any object in freefall experiences microgravity conditions, which occur when the object falls toward the Earth with an acceleration equal to that due to gravity alone (approximately 9.8 meters per second squared [m/s2], or 1 g at Earth's surface). Brief periods of microgravity can be achieved on Earth by dropping objects from tall structures. Longer periods are created through the use of airplanes, rockets, and spacecraft. The microgravity environment associated with the space shuttle is a result of the spacecraft being in orbit, which is a state of continuous freefall around the Earth.

Space Product Development Fundamental Microgravity Research in the Physical Sciences combines cutting-edge experimental facilities with long-duration access to low-Earth orbit and beyond to overcome gravity-induced limitations and to enable new scientific discoveries. The program is sponsoring multi-disciplinary research in fundamental and applied sciences, addressing the details of physical and chemical processes in both non-living as well as biological systems. The ground-based and flight research drives technological innovation for space exploration and Earth-based applications. Elements in the program include combustion science, fluid physics and engineering, fundamental physics, and materials science. Guiding the research in all of these fields are three major goals of the program: to build and sustain a fundamental research program enabled by the space environment, to create a knowledge base to enable future exploration mission technologies, and to return tangible value from the nation's investment in space. In addition to flight-based research, there is a strong ground-based program carrying out leading-edge research in all the above mentioned disciplines. The program supports experimental, theoretical, and numerical modeling activities to develop the foundation for a rigorous and productive flight-based program.

A Review Of Geophysical Methods Used In Archaeology Paper by Jeffrey C. Wynn which discusses the uses of electrical resistivity, magnetics, and groundprobing radar, as well as microgravity, radiometric, thermal infrared imagery, and sonic or seismic techniques. http://www.terraplus.com/papers/wynn.htm
Extractions: ABSTRACT Before proceeding further, a digression into essential terminology is necessary. "Archaeogeophysics" and "archaeological prospection" are the terms most commonly applied to the field described in this paper. This field includes geophysical methods used in site prospection but not isotopic provenance or archaeomagnetic dating. Provenance, incidentally, (sometimes spelled "provenience") is the study of the source of ancient artifacts to document ancient trade and communication patterns (Aitken, 1974). The latter technologies are included along with prospection methods in the broader term "archaeophysics." A survey of the broader field of physics applied to archaeology is available in excellent summaries by Aitken (1974), and Wolfman (1984). Archaeologists frequently use the term rescue archaeology." It refers to emergency evaluation of an area for human cultural resources. This normally is done, under pressure, in advance of industrial development (the bulldozer used to prepare a site for modern human cultural occupation). It is nearly impossible to do this effectively without assistance from geophysical methods. The term "non-destructive archaeology" refers to using remote sensing" methods to provide three-dimensional information about a large tract of land. The key element here is that the evaluation is done without disturbing the land. Archaeologists commonly use the term "remote sensing," incidentally, for more than just photo or LANDSAT image analysis. For them, it includes the whole range of surface geophysical and geochemical methods.
