The recently-rechristened Environmental Sciences Service Administration (previously the U.S. Weather Bureau) launches, with the help of NASA, the first “Operational TIROS” weather satellite, ESSA-1. Based on the architecture of the later TIROS satellites, this is intended to be the first fully-operational, long-life weather satellite, in the tradition of many of the long-lived TIROS weather satellites. But eight months into its operational lifetime, ESSA-1’s on board camera system fails, rendering it blind – it becomes useless as a weather satellite and is kept online for engineering experiments until spring 1967.
