NOAA-19

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 6 February 2009.

Launch

On 4 November 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 27 January 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 06, 2009 aboard a Delta II flying in the 7320 configuration from Vandenberg Air Force Base.
