NOAA-19, designated NOAA-N' (NOAA-N Prime) prior to launch, is the last of the United States National Oceanic and Atmospheric Administration's POES series of weather satellites (which was scheduled to be replaced by the next-generation NPOESS series before the NPOESS project was cancelled). NOAA-19 was launched on February 6, 2009.
On November 4, 2008, NASA announced that the satellite had arrived at Vandenberg aboard a C-5 Galaxy military transport aircraft. Installation of the payload fairing took place January 27, 2009; second stage propellant was loaded on 31 January.
Several attempts were made to conduct the launch. The first attempt was scrubbed after a failure was detected in a launch pad gaseous nitrogen pressurization system. The second attempt was scrubbed after the failure of a payload fairing air conditioning compressor, which is also part of the ground support equipment at the launch pad.
The satellite was successfully launched at about 2:22 a.m. PST. February 6, 2009 aboard a Delta II flying in the 7320 configuration from Vandenberg Air Force Base.
NOAA-N Prime carries a suite of instruments that provides data for weather and climate predictions. Like its predecessors, NOAA-N Prime provides global images of clouds and surface features and vertical profiles of atmospheric temperature and humidity for use in numerical weather and ocean forecast models, as well as data on ozone distribution in the upper part of the atmosphere, and near-Earth space environments—information important for the marine, aviation, power generation, agriculture, and other communities. The NOAA-N Prime primary instruments —the Advanced Very High Resolution Radiometer (AVHRR/3), High Resolution Infrared Radiation Sounder (HIRS/4), and the Advanced Microwave Sounding Unit (AMSU-A)—were all designed for a three-year mission. The Solar Backscatter Ultraviolet Spectral Radiometer (SBUV/2) was designed for a two-year mission, and the Microwave Humidity Sounder (MHS) was designed for a five-year mission.
