TIROS-10

NASA and the United States Weather Bureau launch the tenth and final experimental TIROS weather satellite, TIROS-10. Continuing to test technological upgrades for a fully-functional weather satellite fleet, TIROS-10 also provides additional coverage during hurricane seasons, and remains operational for exactly two years, at which point NASA begins a planned shutdown and phase-out of the experimental TIROS satellites in favor of the Nimbus and ESSA weather satellites.
