Launch Date - End 24 October 1978 - 1 August 1994
État Decommissioned
Orbit type sun-synchronous
Satellite family: Nimbus
Nimbus is a NASA meteorological research-and-development satellite program (parallel to the operational TIROS program) which started in 1963 with the prime objective to test new instrument concepts (introduction of sensor technology), a secondary objective was to provide atmospheric data for improved weather forecasts. Eventually, the series grew more into a major Earth sciences program (study of oceans, land surfaces and atmosphere) with the availability of better sensing instrumentation. The ERTS (Earth Resources Technology Satellite, later renamed to Landsat-1) program, developed in the early 1970s, is a direct descendent of the Nimbus program.Sensor characteristics
