The Geostationary Operational Environmental Satellite Program (GOES) is a joint
effort of NASA and the National Oceanic and Atmospheric Administration (NOAA).
Currently, there are two satellites GOES-12 and GOES-10 operating as 'GOES-East'
and 'GOES-West'. These spacecraft help meteorologists observe and predict local
weather events, including thunderstorms, tornadoes, fog, flash floods, and
other severe weather. In addition, GOES observations have proven helpful in
monitoring dust storms, volcanic eruptions, and forest fires.
GOES - NO/P is the next series of GOES satellites. The GOES-R Series, which is
currently in the formulation phase, will follow GOES - NO/P. The first launch
is scheduled for the 2012 timeframe.
