Teacher Background: How Satellites Work
example, a field of wheat might look pink; clear water may appear black. Back to Top How are satellites launched? The trick to launching a satellite is getting it high enough to do its job without losing the capsule to outer space. It's a delicate balance o...
Tracking Clouds (DAAC Study)
common birthplaces of many storms. Currently, the cloud motion data used to derive wind measurements are observed from geostationary satellites. These instruments orbit the equator, obtaining images of the Earth’s surface below to roughly 55 d...
Who wrote the Book of Life?
life-like patterns could help cut the immense scale of the Book of Life project down to a more manageable size. Â Left: How the computer neural network sees microbial life forms. From left to right: rods, cocci, filaments. An 8x8 pixel microbi...

has argued that this interpretation of network activity provides a quantitative, neurally-inspired basis for prototype theories of concepts developed recently in cognitive psychology. Using this theoretical development, Paul Churchland (1987, 1989) has offe...
On a Clear Day (DAAC Study)
studies claim there are problems," said Robert Cess an atmospheric scientist at the State University of New York at Stony Brook. Since many of the studies used short-term data sets, Cess and Xiaodu Jing, a Ph.D. candidate at SUNY, designed an experiment to test ...

U.S. Satellite Imagery, 1960-1999
detect buried structures, such as missile silos or underground construction, as a result of the heat they generate. Since thermal infrared imagery does not require visible light, it can be obtained under conditions of darkness--if the sky is free of cloud co...

and from those of some other Federal agencies. In addition, many images from such space programs as Landsat, begun in 1972, are held by the USGS. Most satellite scenes can be obtained only in digital form for use in computer-based image processing a...
Fish in the Trees (DAAC Study)
woody vegetation that are important unknown parameters in regional biogeochemical and hydrologic models. Historically, obtaining any satellite data from the Amazon basin has been as difficult as gaining physical access; radar images have provided the only reliable sourc...
