Abstract:

The National Polar-orbiting Operational Environmental Satellite System NPOESS is a triagency acquisition managed by the Department of Commerces National Oceanic and Atmospheric Administration NOAA, the Department of Defense DOD, and the National Aeronautics and Space Administration NASA that has experienced escalating costs, schedule delays, and technical difficulties. These factors led to a June 2006 decision to restructure the program by reducing the number of satellites and sensors, increasing estimated costs to 12.5 billion, and delaying the first two satellites by 3 to 5 years. Among other objectives, GAO was asked to evaluate progress in restructuring the acquisition, assess the status of key program components and risks, and assess NASAs, NOAAs, and DODs plans for obtaining the data originally planned to be collected by NPOESS sensors, but eliminated by the restructuring. To do so, GAO analyzed program and contractor data, attended program reviews, and interviewed agency officials.
