In the future, the National Polar-orbiting Operational Environmental Satellite System (NPOESS) is to combine the two current satellite systems into a single state-of-the-art environment monitoring satellite system. This new satellite system is considered critical to the United States' ability to maintain the continuity of data required for weather forecasting and global climate monitoring through the year 2020. Because of changes in funding levels after the contract was awarded, the program office recently developed a new cost and schedule baseline for NPOESS. GAO was asked to provide an interim update to (1) identify any cost or schedule changes as a result of the revised baseline and determine what contributed to these changes and (2) identify factors that could affect the program baseline in the future. In commenting on a draft of this report, DOD, NOAA, and NASA officials generally agreed with the report and offered technical corrections, which we incorporated where appropriate. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-04-1054/html/GAOREPORTS-GAO-04-1054.htm GAO-04-1054 https://www.govinfo.gov/app/details/GAOREPORTS-GAO-04-1054 Other Written Product GAO-04-1054; Polar-Orbiting Environmental Satellites: Information on Program Cost and Schedule Changes; Cost overruns Earth resources satellites Environmental research Future budget projections Interagency relations Life cycle costs Procurement planning Research and development contracts Schedule slippages Environmental monitoring Polar-orbiting satellites Defense Meteorological Satellite Program National Polar-Orbiting Operational Environmental Satellite System
