Earth Observation Satellites

Earth Observation Satellites

1. EARTH OBSERVATION SATELLITES

2. Earth observation satellites are satellites specifically designed to observe Earth from orbit. Earth-observation satellites help us monitor and protect our environment, manage our resources

3. Uses: Environmental monitoring Meteorology Mapping of terrain

4. ASTER Advanced Spaceborne Thermal Emission And Reflection Radiometer Government of Japan and NASA One of the 5 payloads on the Terra Satellite Terra (EOS AM-1)
