Landsat 7

NSSDCA/COSPAR ID: 1999-020A

Description

Landsat 7 continued the long-term earth observation Landsat program begun in 1972. Landsat 7 was a joint project between NASA, NOAA, and the US Geological Survey to obtain continuous high-resolution imagary of the earth's surface for environmental monitoring, disaster assessment, land use and regional planning, cartography, range management, oil and mineral exploration. Under the Land Remote Sensing Act of 1992 (PL 102-555), the Landsat program returned to the US Government and responsibilities assigned to NASA, NOAA, and the USGS. The Landsat 7 carried one instrument: (the Enhanced Thematic Mapper Plus (ETM+) The ETM+ was an improved version of the ETM on Landsat 6. The instrument provided improved spatial resolution. The Landsat 7 spacecraft provided improved ephemeris and attitude determination. The Landsat 7 spacecraft was built by Lockheed Martin Missiles and Space.
