First Generation TIROS series - research satellites with: TV cloud imagery scanning IR radiometer low resolution E.R.B. experiments DMSP - Defense Meteorological Satellite Program (classified until 1973) IR; cloud cover information ESSA (TOS) became operational system Nimbus series - NASA research series with: passive radiometric sensors for sounding atmosphere survey land and ocean surfaces 7th operated for about 10 years experiments became operational instruments on several systems (IR/MW sounding, MW imaging, Ocean color, ERB) ATS - geostationary research series first multispectral imagery from geostationary orbit SMS and then GOES became operational system
Second Generation Landsat - land (earth resources) research NOAA - series of operational polar orbiters SMS/GOES - operational geostationary Third Generation TIROS-N/NOAA - operational polar orbiters, advanced sounders and imagers GOES - added sounders from geostationary orbit Additional research systems: SAGE ERBE Seasat - active and passive MW for ocean remote sensing (1978) GEOS-3 - altimeter (1975) Landsat - 4/5 and many other Current Generation - too many to list completely

Objectives: Seasat A was the first satellite designed for sensing of the Earth's oceans with active microwave instruments. Specific objectives were to collect data on sea-surface winds, ocean topography, sea-surface temperatures, wave heights, wave length and direction, atmospheric water, and sea ice features. The mission ended after 116 days due to a failure of the vehicle's electric power system. The mission demonstrated the feasiblity of using microwave sensors to monitor ocean conditions, and laid the groundwork for future ocean missions. The major difference between Seasat-A and previous Earth observation satellites was the use of active and passive microwave sensors to achieve an all-weather capability.
