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
Meteor (satellite) Meteor (satellite) The Meteor spacecraft are weather observation satellites launched by the USSR and Russia. The Meteor satellite series was developed during the 1960s. The Meteor satellites were designed to monitor atmospheric and sea-surface temperatures, humidity, radiation, sea ice conditions, snow-cover, and clouds. Meteor 1-26 was considered to be the most likely candidate for a 7 January 2017 satellite near collision. The Joint Space Operations Center which announced the possible collision didn't identify the satellites involved but third-party observers were of the opinion that Meteor 1-26 and DMSP F15 were the most likely candidates. Meteor-2-21/Fizeau is the twenty-first and last
