1965: First view of the whole world’s weather (TIROS-9)

This first image of weather systems over the entire sunlit side of Earth is made up of 450 images taken by TIROS-9 over a 24-hour period on Feb. 13, 1965. During each 2-hour orbit, two television cameras sent images to radio ground stations in Alaska and Virginia, which then relayed the data to Washington where they were converted into pictures.
