NASA provided launch services; NOAA initially oversaw satellite operations. Landsat 4 operations were contracted out to the Earth Observation Satellite Company (EOSAT) corporation in 1984, and the USGS archived records and distributed data. The mission was unique in that it was the first observatory to use the Thematic Mapper (TM). The sensor had seven spectral bands, three in visible part of the spectrum and four in the infrared.
