The latest polar-orbiting operational environmental weather satellite developed by NASA for the National Oceanic and Atmospheric Administration, called NOAA-N Prime, is offloaded from the trailer at Vandenberg Air Force Base, Calif. The spacecraft will be moved into a NASA payload processing facility and prepared for a Feb. 4 launch. NOAA-N Prime, built by Lockheed Martin, is similar to NOAA-N launched on May 20, 2005.
