Space astronomy allows access to wavelength regions that are not available to ground-based observatories.
The Space Infrared Telescope Facility (SIRTF), the fourth of the Great Observatories, will be placed in a unique solar orbit trailing the Earth, in 2001.

Recent automated and advanced techniques developed at JPL have created a streamlined and fast-track approach to initial mission conceptualization and system architecture design, answering the need for rapid turnaround of trade studies for potential proposers, as well as mission and instrument study groups.
SIRTF represents an important scientific and technical bridge to NASA's new Origins program, and is managed for NASA by the Jet Propulsion Laboratory, California Institute of Technology.
Philosophical and technical backgrounds for the application of remote sensing by earth scientists are presented. Interests and activities of participating agencies of the United States and Canadian governments, universities, and the private sector in implementing satellite technology in a diverse array of water-related programs are described. Consideration is then given to applications of satellite data to the various aspects of the hydrologic cycle and man's impact on it: meteorology, snow and ice, surface water, soil moisture, ground water, wetlands, coastal zone, water quality and environment, and water use and management.
Flooding was detected along the Mississippi River and some of its tributaries by the multispectral scanner (MSS) on the ERTS-1 on at least three orbits during the spring of 1973. The ERTS data provided the first opportunity for mapping the regional extent of flooding. Special optical data processing techniques were used to produce a variety of multispectral color composites enhancing flood-plain details. One of these, a 2-color composite of near infrared bands 6 and 7, was enlarged and registered to 1:250,000-scale topographic maps and used as the basis for preparation of flood image maps. Two specifically filtered 3-color composites of MSS bands 5,6, and 7 and 4, 5, and 7 were prepared.
