Associated Programs
  • Tiros TIROS spacecraft were the beginning of a long series of polar-orbiting meteorological satellites. TIROS was followed by the TOS (TIROS Operational System) series, and then the ITOS (Improved TIROS) series, and later the NOAA series. TIROS spacecraft were developed by GSFC and managed by ESSA (Environmental Science Services Administration). The objective was to establish a global weather satellite system. More...
