In April of 1991, the U.S. National Aeronautics and Space Administration concluded that o2one depletion was occurring even faster than had been estimated, and at the third meeting of the patties to the Montreal Protocol in June of 1991, an eadiet phaseout of controlled substances was proposed. An assessment of the technical and economic consequences of a 1997 phaseout is cuttendy underway, and further acceleration of the phaseout schedule to as soon as 1995 seems likely. Many countnes already have undatetaHy banned or curbed the use of controlled substances well ahead of the Montreal Protocol timetable. As of eadyjuly 1992, there were 81 parties to the Protocol.

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 equilibrium solubility of common inorganic gases in petroleum liquids can now be estimated by nomograph. The relationship is based on an earlier correlation established by the U.S. National Aeronautics and Space Administration and the subject of a standard method approved by the American Society of Testing and Materials. 

This work was funded by the U.S. National Aeronautical and Space Administration (Contract NASW-99044). The DEM and GIS infrastructure data were supplied by the Pacific Disaster Center. The method for preparing the two-dimensional flood maps is based in part by a method described to us by Andy Rost of the National Operational Hydrologic Remote Sensing Center.

The largest volcano on Mars, Olympus Mons, Is much larger than the largest volcano on Earth. Olympus Mons Is over 15.5 miles (25 km) tall, three times as tall as Mt. Everest, and has a base the size of the state of Arizona.This photo shows how large Olympus Mons Is compared to Arizona. U.S. National Aeronautics and Space Administration (NASA). 

Bright rayed craters and large craters, called basins, are prominent in this vi of Mercury Because, unlike Earth and Mars, Mercury has no atmosphere, its landscape is not continuously shaped by erosion and deposition. Aithough the exterior of Mercury resembles that of the Moon, the interior of the planet is probably more similar to that of Earth. U..S. National Aeronautics and Space Administration (NASA). 

A photo of the full moon taken from Apolto 77.The mare regions, which are relatively flat, appear as dark areas because they reflect less light.The highlands are lighter In color and have a more rugged surface than the mare. About 1 of the surface shown In this picture cannot be seen from the Earth. U.S. National Aeronautics and Space Administration Q ASA). JLM dsuals. Reproduced by permission.

Great scientific discoveries and important scientific expeditions are usually thought of, planned, and carried out by scientists, but major projects that involve the investment of billions of dollars of public money are often administered and managed by individuals who have little or no background in science and technology itself. The efforts of such individuals are often responsible for the ultimate success (orfailure) of research projects. One of the best examples of this truism is James E. Webb, second administrator of the U.S. National Aeronautics and Space Administration (NASA).

The Atlas and Catalogue of infrared sources in the Magellanic Clouds was prepared from data obtained with the Infrared Astronomical Satellite (IRAS). IRAS was developed and operated by the Netherlands Agency for Aerospace Programs (NIVR), the U.S. National Aeronautics and Space Administration (NASA) and the U.K. Science and Engineering Research Council (SERC).
