The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is an imaging
instrument onboard Terra, the flagship satellite of NASA's Earth Observing System
(EOS) launched in December 1999.
ASTER is a cooperative effort between NASA, Japan's Ministry of Economy, Trade
and Industry (METI), and Japan Space Systems
(J-spacesystems). ASTER data is used to create detailed maps of land surface temperature, reflectance,
and elevation. The coordinated system of EOS satellites, including Terra, is a major component
of NASA's Science Mission Directorate and the
Earth Science Division.
The goal of NASA Earth Science is to develop a scientific understanding of the Earth as an
integrated system, its response to change, and to better predict variability and trends in climate,
weather, and natural hazards.
