Highly integrated Pluto payload system (HIPPS): A sciencecraft instrument for the Pluto mission Highly integrated Pluto payload system (HIPPS): A sciencecraft instrument for the Pluto mission
We describe the design concept for the highly integrated Pluto payload system (HIPPS): a highly integrated, low-cost, light-weight, low-power instrument payload designed to fly aboard the proposed NASA Pluto flyby spacecraft destined for the Pluto/Charon system. The HIPPS payload is designed to accomplish all of the Pluto flyby prime (IA) science objectives, except radio science, set...

Dynamic mapping of urban regions: Growth of the San Francisco/Sacramento region Dynamic mapping of urban regions: Growth of the San Francisco/Sacramento region
A methodology has been developed to document the tremendous growth large metropolitan regions have experienced over time. A GIS was used to compile a database of urbanization for the San Francisco/ Sacramento urban region spanning 140 years. Historical records, USGS topographic maps, aerial photographs, and Landsat imagery were used to identify the urban spatial extent. Digital...

Microwave radiometers and their application in field and aircraft campaigns for remote sensing of land and water surfaces Microwave radiometers and their application in field and aircraft campaigns for remote sensing of land and water surfaces
The paper presents an overview of the scientific investigations and practical applications of a group of specialists working in the Institute of Radioengineering and Electronics of the Russian Academy of Sciences (IRE RAS) with their partners in Russia and the USA in the area of passive microwave remote sensing as applied to the study of soil, vegetation and water bodies. Applications...

A regional monitoring network to investigate the occurrence of agricultural chemicals in near-surface aquifers of the midcontinental USA A regional monitoring network to investigate the occurrence of agricultural chemicals in near-surface aquifers of the midcontinental USA
Previous state and national surveys conducted in the mid-continental USA have produced a wide range in results regarding the occurrence of agricultural chemicals in groundwater. At least some of these differences can be attributed to inconsistencies between the surveys, such as different analytical reporting limits. The US Geological Survey has designed a sampling network that is...
