Book Description
The U.S. Government Accountability Office (GAO) is an independent agency that works for Congress. The GAO watches over Congress, and investigates how the federal government spends taxpayers dollars. The Comptroller General of the United States is the leader of the GAO, and is appointed to a 15-year term by the U.S. President. The GAO wants to support Congress, while at the same time doing right by the citizens of the United States. They audit, investigate, perform analyses, issue legal decisions and report anything that the government is doing. This is one of their reports.

Book Description
Following the decision to disband the National Polar-orbiting Operational Environmental Satellite System (NPOESS) program in 2010, both the National Oceanic and Atmospheric Administration (NOAA) and the Department of Defense (DOD) made initial progress in transferring key management responsibilities to their separate program offices. Specifically, NOAA established a Joint Polar Satellite System (JPSS) program office, documented its requirements, and transferred existing contracts for earth-observing sensors to the new program. DOD established its Defense Weather Satellite System program office and modified contracts accordingly. However, recent events have resulted in major program changes at both agencies. NOAA plans to revise its program requirements to remove key elements, including sensors and ground-based data processing systems, to keep the program within budget. Further, in early 2012, DOD decided to terminate its program and reassess its requirements. Over the past year, NOAA has made progress in developing its satellite system, but critical decisions and milestones lie ahead. In October 2011, the JPSS program office successfully launched a satellite originally called the NPOESS Preparatory Project (NPP). Data from the satellite are currently being calibrated and validated, and NOAA meteorologists started using selected satellite data products in their weather forecasts in May 2012. Further, the three major components of the JPSS program (the flight, ground, and free-flyer projects) are at different stages of development. Within the flight project, development of the sensors for the first JPSS satellite is well under way; however, selected sensors are experiencing technical issues. The ground project is currently in operation supporting NPP and NOAA is planning to upgrade parts of the ground system infrastructure to increase its security and reliability. The free-flyer project, intended to integrate and launch key instruments that could not be accommodated on the JPSS satellites, is still in a planning stage because NOAA has not yet decided which satellites will host the instruments or when these satellites will launch. The JPSS program office has implemented elements of an effective risk management process; however, the program still faces significant risks. It does not yet have a cost and schedule baseline in place, the program office is not yet fully staffed, and there will likely be a gap in satellite data lasting 17 to 53 months from the time NPP is projected to cease operations and the first JPSS satellite begins to operate. There are also potential satellite data gaps in the DOD and European polar satellite programs, which provide supplementary information to NOAA forecasts. The JPSS program office is managing the first two risks, but NOAA has not established plans to mitigate potential satellite gaps. Until these risks are mitigated and resolved, civilian and military satellite data users may not have the information they need for timely weather forecasting, thereby risking lives, property, and commerce.

Book Description
In the 8 years since a contract was awarded, the National Polar-Orbiting Operational Environ. Satellite System (NPOESS) -- a tri-agency program managed by NOAA, DoD, and NASA -- has experienced escalating costs, schedule delays, and ineffective interagency mgmt. The launch date for a demo. satellite has been delayed by 5 years and the cost estimate for the program has more than doubled. In Feb. 2010, NPOESS was disbanded, and, instead, the agencies have undertaken separate acquisitions. This report: (1) assessed efforts to establish separate satellite programs; (2) evaluated the status and risks of the NPOESS components still under development; and (3) evaluated the implications of using the demo. satellite's data operationally.

Book Description
The National Polar-Orbiting Environmental Satellite System (NPOESS) is a tri-agency acquisition -- managed by the DoD & NASA -- which experienced escalating costs, schedule delays, & technical difficulties. These factors led to a June 2006 decision to restructure the program, thereby decreasing the program¿s complexity, increasing its estimated cost to $12.5 billion, & delaying the first two satellites by 3 to 5 years. The author was asked to: (1) assess progress in restructuring the acquisition; (2) evaluate progress in establishing an effective mgmt. structure; (3) assess the reliability of the cost & schedule estimate; & (4) identify the status & key risks facing the program¿s major segments. Includes recommendations. Charts & tables.

Book Description
In summary, today's polar-orbiting weather satellite program is essential to a variety of civilian and military operations, ranging from weather warnings and forecasts to specialized weather products. NPOESS is expected to merge today's two separate satellite systems into a single state-of-the-art weather and environmental monitoring satellite system to support all users. This new satellite system is expected to provide vast streams of data, far more than are currently handled by the four central processing centers. To prepare for these increased data volumes, the four data processing centers must address key data management challenges including building up their respective infrastructures and working to be able to efficiently incorporate new data in their derived weather products and models. Because the NPOESS launch date is still several years in the future, the four processing centers and the integrated program office have time to continue to develop, define, and implement their plans to address key data management challenges. Each of the processing centers is planning activities to build its capacity to handle increased volumes of data, but more can be done to coordinate and define these plans-including sharing information on what is needed in order for the centers to use particular weather products and developing a plan to address these scientific issues. Unless more is done to coordinate and define these plans, the centers could risk delays in using NPOESS data in operational weather products and forecasts.
