A series of meteorological satellites placed in geostationary orbit by NASA. The first generation comprised eight satellites, designated GOES-A to GOES-H, launched in 1975, 1977, 1978, 1980, 1981, 1983, 1986 (launch failed), and 1987; all are now out of commission. The second generation comprised GOES-I to GOES-M, launched in 1994, 1995, 1997, 2000, and 2001; all are now out of commission. GOES-N (launched 24 May 2006, at 75°W), GOES-O (launched 27 June 2009, at 105°W), and GOES-P (launched 4 March 2010, at 135°W) are second-generation satellites still in operation. GOES-Q was cancelled. GOES-R, launched 19 November 2016, is the first in the third generation.
