The first Earth Observing System (EOS) satellite called Terra (previously AM-1) was launched on December 18, 1999. ASTER data contributes to a wide array of global change-related application areas including vegetation and ecosystem dynamics, hazard monitoring, geology and soils, hydrology, and land cover change. It’s also perfect background material for your home PC.

But it’s not just pretty pictures that NASA is releasing – this is useful data, which all of us can use for our own studies. Whether you’re a professional or an amateur, you can draw valuable information from these images. Example applications include monitoring glacial advances and retreats, monitoring potentially active volcanoes, identifying crop stress, determining cloud morphology and physical properties, evaluating wetlands, monitoring thermal pollution, monitoring coral reef degradation, mapping surface temperatures of soils and geology, and measuring surface heat balance.

“We anticipate a dramatic increase in the number of users of our data, with new and exciting results to come,” said Michael Abrams, ASTER science team leader at NASA’s Jet Propulsion Laboratory in Pasadena, California, home to ASTER’s U.S. science team. ASTER data are processed into products using algorithms developed at JPL and the National Institute of Advanced Industrial Science and Technology (AIST) in Japan. A joint U.S./Japan science team validates and calibrates the instrument and data products.

The 2.95 million individual scenes that have been released can be accessed through the Land Processes Distributed Active Archive Center with a smaller (and more easily accessible) selection on the ASTER website.

Andrei's background is in geophysics, and he's been fascinated by it ever since he was a child. Feeling that there is a gap between scientists and the general audience, he started ZME Science -- and the results are what you see today.
