ASTER is a cooperative effort between NASA and Japan's Ministry of Economy
Trade and Industry (METI), with the collaboration of scientific and industry organizations
in both countries. The ASTER instrument provides the next generation in
remote sensing imaging capabilities when compared to the older Landsat Thematic Mapper and Japan's JERS-1 OPS scanner.
ASTER captures high spatial resolution data in 14 bands, from the visible to the
thermal infrared wavelengths, and provides stereo viewing capability for digital
elevation model creation. As the "zoom lens" for Terra, ASTER data are used by
other Terra and space-borne instruments for validation and calibration.
Above is an illustration of the Terra spacecraft with the ASTER instrument
highlighted. The links to the left under "Mission" will tell you about EOS, science
applications, the instrument, and the ASTER airborne simulator.
