TIROS-1 prototype on display at the Smithsonian National Air and Space Museum.

TIROS-1 was the World's first ever weather satellite and was sent up in the hope it may help hurricane detection work back on earth. Vanguard 2 did also take several low quality pictures of clouds between 1959 and 1969. The optical scanner experiment was designed to obtain cloud-cover data between the equator and 35° to 45° N latitude.

It is to be noted that modern services like Google Maps, hurricane tracking services and satellite TV all owe a debt to these early satellites.
