NOAA-N Prime Launch Scrubbed

NASA scrubbed the launch of the Lockheed Martin NOAA-N Prime weather satellite at 2 a.m. PST Feb. 4 when a pressurization system on the Boeing Delta II rocket failed.
An immediate repair of the gaseous nitrogen pressurization system was undertaken on the launch pad at Vandenberg Air Force Base, Calif., and a second attempted launch was set for 2:22 a.m. PST Feb. 5. But NASA later announced that the launch had been postponed for an additional 24 hours and is now set to take off on Feb. 6 at 2:22 a.m. PST.
The system maintains pressurization and purges of various components on the rocket.
The satellite is the 16th in a series of polar-orbiting weather satellites that NASA has launched for the National Oceanic and Atmospheric Administration over the past 31 years.
