A smaller factor in ozone depletion is the rising levels of N2O in the atmosphere from combustion and the use of nitrogen-rich fertilizers, since they ate the sources of NO in the stratosphere that can destroy ozone catalyticaHy. Another concern in the depletion of ozone layer, under study by the National Aeronautics and Space Administration (NASA), is a proposed fleet of supersonic aircraft that can inject additional nitrogen oxides, as weU as sulfur dioxide and moisture, into the stratosphere via their exhaust gases (155). Although sulfate aerosols can suppress the amount of nitrogen oxides in the stratosphere...

Since World War 11, the U.S. space program and the military have used small amounts of insoluble chromates, largely barium and calcium chromates, as activators and depolarizers in fused-salt batteries (214,244). The National Aeronautics and Space Administration (NASA) has also used chromium (111) chloride as an electrolyte for redox energy storage cells (245).

The Montreal Protocol of July 1987 resulted in an international treaty in which the industrialized nations agreed to halt the production of most ozone-destroying chlorofluorocarbons by the year 2000. This deadline was hastily changed to 1996, in February 1992, after a U.S. National Aeronautics and Space Administration (NASA) satellite and high-altitude sampling aircraft found levels of chlorine monoxide over North America that were 5i % greater than that measured over Antarctica. 

The fuel eell is a nineteenth eentuiy invention in the twentieth eentury it heeame the heart of an eleetroehemical power plant and power souree, whieh is now in a stage of advaneed technology development. Its first and only applieation since the early 1960s, has been as an auxiliary power souree for spaee flights by the National Aeronautics and Space Administration (NASA). During the past decade, development for terrestrial (eivihan and defense) applieations has led to its commercialization and research on utilization in a variety of applications. Programs in the United States, Japan, Europe, and some other eoimtries are focused on the development of fuel cell power plant/power sources for (1) base-load,...

SIMS imaging was theoretically invented in 1949 by Herzog and Viehb of the Vienna University in Austria. The first SIMS device was completed by Liebel and Herzog in 1961 with the support of the National Aeronautics and Space Administration (NASA) and was used to analyze metal surfaces. However, it was not suitable for analyzing biological macromolecules because the second electronic ion beam breaks the molecules into atoms. 

This effort was funded by the National Aeronautics and Space Administration (NASA) Grant NNX07AB93A under a project entitled Basic Studies for the Production and Upgrading of Fischer-Tropsch Synthesis Products to Fuels and the Commonwealth of Kentucky. This research was carried out, in part, at the National Synchrotron Light Source, Brookhaven National Laboratory, which is supported by the U.S. DOE, Divisions of Materials Science and Chemical Sciences. Special thanks to Dr. Nebojsa Marinkovic (Beamline X18b, NSLS, Brookhaven) for help with X AFS studies and Joel Young (University of Oklahoma, Department of Physics) for XAFS cell construction.

Space Stations. The final example I have selected results from work done by the National Aeronautics and Space Administration (NASA) in preparation for flying the space station. NASA s general problem is that many space station systems must be repairable in orbit by astronauts who will not be familiar with the detaib of all the systems. Therefore, NASA is looking to the technology of expert systems to diagnose problems and provide advice to the astronauts on how to repair the problems. 

Foil balloons are derived from the effort of National Aeronautics and Space Administration (NASA) Space Command with the concept and technology to metalizate plastic sheeting. While the balloons are often referred to as Mylar or silver Mylars, they are not made from Mylar, a trade name for certain polyester film. They should be simply referred to as foil balloons. They are made from nylon film coated on one side with PE and metallized on the other. The nylon film gives the balloon some strength and the PE gives it some flexibility and helps retard the release of the held gas.

Smart systems involve sensing changing conditions and activating some sort of response, usually with an actuator. A project known as Active Aeroelastic Wing (AAW), conducted by the National Aeronautics and Space Administration (NASA), the U.S. Air Force Research Laboratory, and Boeing Company, studied wing elasticity in a modi-...
