US weather satellite launch deferred
The NOAA-N Prime satellite was scheduled to be launched aboard a Delta 2 rocket early Wednesday, but the mission was put off after a problem with gaseous nitrogen system, which is used to pressurise the liquid oxygen tank and control systems was detected.
The launch is expected to be the last in a series of polar-orbiting satellites that have been observing Earth's weather since 1960. NOAA-N Prime has sensors that will be used in the Search and Rescue Satellite-Aided Tracking System to monitor for distress signals around the world.
However, the National Oceanic and Atmospheric Administration, which manages the $ 564 million mission, did not immediately say when the launch would take place.
The weather office has predicted rains from Thursday till the weekend which could pose some problems.
