Weather satellite of rotation and its elliptical orbit kept it from collecting a notable amount of useful data. The Explorer VI and VII satellites also contained weather-related experiments. The first weather satellite to be considered a success was TIROS-1, launched by NASA on April 1, 1960. TIROS operated for 78 days and proved to be much more successful than Vanguard 2. TIROS paved the way for the Nimbus program, whose technology and findings are the heritage of most of the Earth-observing satellites NASA and NOAA have launched since then. Beginning with the Nimbus 3 satellite in 1969, temperature information through the tropospheric
History of The Weather Channel plan for the new network was that it would be able to provide localized weather information to its viewers. This would be done through the use of specialized computer units, known as WeatherStars ("STAR" being an acronym for "Satellite Transponder Addressable Receiver"), which would be installed at the headends of cable providers that agreed to carry the channel. These WeatherStars were able to insert current local conditions, forecasts and weather warnings over the national feed, with the weather data being received from the vertical blanking interval of the TWC video feed and via satellite, which is then transmitted to the
