The first satellite in the GOES program (GOES-1) was launched on October 16, 1975 and quickly became an essential component of services provided by the National Weather Service. From the earliest days of the GOES program, implementing satellite imagery to perform such tasks as tracking hurricanes and volcano ash, as well as deriving cloud drift winds and their temperatures, were (and still are today) used by operational forecast centers to help with analyses in data sparse areas.
The newer satellites have benefited from the experiences of the other seven (GOES-1 through GOES-7) and results are shown through their improved capabilities. GOES-7 (pictured below) was only recently discontinued in 1995 and replaced by the more advanced GOES-9.
