The Terra (formerly called EOS AM-1) satellite is the flagship of NASA’s Earth Science Missions. Terra is the first EOS (Earth Observing System) platform and provides global data on the state of the atmosphere, land, and oceans, as well as their interactions with solar radiation and with one another.
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is an imaging instrument flying on Terra, a satellite launched in December 1999 as part of NASA's Earth Observing System (EOS).
MISR (Multi-angle Imaging SpectroRadiometer) is a scientific instrument on the Terra satellite launched by NASA on December 18, 1999. The device is designed to measure the solar radiation reflected by the Earth system (planetary surface and atmosphere) in various directions and spectral bands.
Measurements of Pollution in the Troposphere (MOPITT) is a payload scientific instrument launched into Earth orbit by NASA on board the Terra satellite in 1999. It is designed to monitor changes in pollution patterns and its effect in the lower atmosphere of the Earth.
