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
Navid (satellite) 3 February 2012. The satellite remained in orbit for two months, before reentering the atmosphere on 1 April 2012. Navid (satellite) Navid () or Navid-e Elm-o San'at (, "Gospel of Science and Technology") was an experimental Iranian Earth observation satellite. The satellite carried a camera for taking higher resolution imagery of Earth and it was also be used to collect weather data and monitor natural disasters. It was developed by students at the Iran University of Science and Technology. The third satellite to be launched indigenously by Iran, it was placed into orbit by a new configuration of the Safir
