VANDENBERG AIR FORCE BASE, CALIF. - Workers on Space Launch Complex 2 at Vandenberg Air Force Base in California secure the engine on the first stage of a Boeing Delta 2 rocket. The rocket will be lifted up the launch service tower. The Delta 2 is the launch vehicle for the National Oceanic and Atmospheric Administration (NOAA-N) spacecraft.The NOAA-N satellite will be placed into a polar orbit aboard a Boeing Delta 2 rocket. The spacecraft will continue to provide a polar-orbiting platform to support (1) environmental monitoring instruments for imaging and measuring the Earth's atmosphere, its surface, and cloud cover, including Earth radiation, atmospheric ozone, aerosol distribution, sea surface temperature, and vertical temperature and water profiles in the troposphere and stratosphere; (2) measurement of proton and electron flux at orbit altitude; (3) data collection from remote platforms; and (4) the Search and Rescue Satellite-Aided Tracking (SARSAT) system. Additionally, NOAA-N is the fourth in the series of support dedicated microwave instruments for the generation of temperature, moisture, surface, and hydrological products in cloudy regions where visible and infrared (IR) instruments have decreased capability. Launch is currently scheduled for no earlier than May 11, 2005.
