Landsat 4
Landsat 4 introduced the Thematic Mapper alongside the Multispectral Scanner after its July 16, 1982 launch. The seven-band Thematic Mapper provided 30 m reflective observations and a 120 m thermal channel, improving spectral coverage and land-surface detail over earlier Landsats. Science collection ended in late 1993, while spacecraft decommissioning followed on June 15, 2001. Its observations remain part of the Landsat archive maintained by USGS EROS.
