CENTER, FL – The
key weather observing instrument on board the nations newest advanced weather
observatory, GOES-17, has suffered a serious anomaly with the cooling system essential
for enabling measurements with most of the spectral bands, say NOAA managers.
GOES-17 failed to start up properly during the normal on-orbit check out and commissioning
phase, said top managers of The
National Oceanic and Atmospheric Administration, or NOAA, at a May 23 media
briefing. NOAA runs the nations fleet of
weather observing satellites.

failure with the cooling system impacts observations from 13 of the 16 spectral
bands in the infrared and near infrared wavelengths. Only the 3 visible band
channels appear to be unaffected at this time.

channels, are significantly affected.”

they are not functioning fully, it is a loss. It is a performance issue we have
