"Prophesying is very difficult, especially when it comes to the future." Forecasting the weather is especially difficult. However, with the arrival of artificial meteorological satellites to the aid of terrestrial weather services, the accuracy of meteorological information has improved 15 times. Today satellites can forecast the weather for 14 days, their radars record the origin of rain and snow, and their sensors make it possible to calculate the temperature of oceans, land areas, and clouds with great accuracy.
Recently, scientists can control the level of the world ocean with satellites help with an accuracy of 1 cm. Which meteo or other satellites do you find most useful or interesting?

On April 1, 1960, NASA's first operational weather satellite, TIROS-1, launched from Cape Canaveral. TIROS stands for Television InfraRed Observation Satellite. On June 15, 1960, an electronics failure occurred. However, this weather satellite can be considered the coolest only because it was the first.
Now we have so much information about different weather phenomena thanks to such projects.
