Polar-Orbiting Operational Environmental Satellites: Restructuring Is Under Way, but Technical Challenges and Risks Remain
GAO-07-498: Published: Apr 27, 2007. Publicly Released: Jun 7, 2007.
The National Polar-orbiting Operational Environmental Satellite System (NPOESS) is a tri-agency acquisition--managed by the Departments of Commerce and Defense and the National Aeronautics and Space Administration--which experienced escalating costs, schedule delays, and technical difficulties. These factors led to a June 2006 decision to restructure the program thereby decreasing the program's co...
Space Acquisitions: Actions Needed to Expand and Sustain Use of Best Practices
GAO-07-730T: Published: Apr 19, 2007. Publicly Released: Apr 19, 2007.
DOD's space system acquisitions have experienced problems over the past several decades that have driven up costs by hundreds of millions, even billions of dollars, stretched schedules by years, and increased performance risks. DOD has recognized the need to change its approach to developing space systems and is attempting to instill best practices in new efforts. GAO was asked to testify on its f...
Space Acquisitions: DOD Needs to Take More Action to Address Unrealistic Initial Cost Estimates of Space Systems
GAO-07-96: Published: Nov 17, 2006. Publicly Released: Nov 17, 2006.
Estimated costs for the Department of Defense's (DOD) major space acquisition programs have increased by about $12.2 billion from initial estimates for fiscal years 2006 through 2011. Cost growth for ongoing Air Force programs above initial estimates accounts for a substantial portion of this 44 percent increase. In light of the role that optimistic estimating is believed to have played in exacerb...
Space Acquisitions: DOD Needs Additional Knowledge as it Embarks on a New Approach for Transformational Satellite Communications System
GAO-06-537: Published: May 24, 2006. Publicly Released: May 24, 2006.
The Department of Defense (DOD) wants to create a networked force where soldiers and systems are able to operate together seamlessly. To help facilitate this transformation, DOD began the Transformational Satellite Communications System (TSAT) program in January 2004. We reported in 2003 that TSAT was about to begin without sufficiently mature technology. In this report, at your request, we follow...
Polar-Orbiting Operational Environmental Satellites: Cost Increases Trigger Review and Place Program's Direction on Hold
GAO-06-573T: Published: Mar 30, 2006. Publicly Released: Mar 30, 2006.
Polar-orbiting environmental satellites provide data and imagery that are used by weather forecasters, climatologists, and the military to map and monitor changes in weather, climate, the oceans, and the environment. They are critical to long-term weather prediction, including advance forecasts of a hurricane's path and intensity. Our nation's current operational polar-orbiting environmental satel...
Polar-Orbiting Operational Environmental Satellites: Technical Problems, Cost Increases, and Schedule Delays Trigger Need for Difficult Trade-off Decisions
GAO-06-249T: Published: Nov 16, 2005. Publicly Released: Nov 16, 2005.
Polar-orbiting environmental satellites provide data and imagery that are used by weather forecasters, climatologists, and the military to map and monitor changes in weather, climate, the oceans, and the environment. Our nation's current operational polar-orbiting environmental satellite program is a complex infrastructure that includes two satellite systems, supporting ground stations, and four c...
National Aeronautics and Space Administration: Long-standing Financial Management Challenges Threaten the Agency's Ability to Manage Its Programs
GAO-06-216T: Published: Oct 27, 2005. Publicly Released: Oct 27, 2005.
Congress asked GAO to testify on the status of the National Aeronautics and Space Administration's (NASA) financial management reform efforts. NASA faces major financial management challenges that, if not addressed, will weaken its ability to manage its highly complex programs. NASA has been on GAO's high-risk list since 1990 because of its failure to effectively oversee its contracts, due in part...
NASA's Space Vision: Business Case for Prometheus 1 Needed to Ensure Requirements Match Available Resources
GAO-05-242: Published: Feb 28, 2005. Publicly Released: Mar 22, 2005.
In 2003, the National Aeronautics and Space Administration (NASA) initiated the Prometheus 1 project to explore the outer reaches of the Solar System. The Prometheus 1 spacecraft is being designed to harness nuclear energy that will increase available electrical power from about 1,000 watts to over 100,000 watts and enable the use of electric propulsion thrusters. Historically, NASA has had diffic...
Space Programs: NASA's Independent Cost Estimating Capability Needs Improvement
NSIAD-93-73: Published: Nov 5, 1992. Publicly Released: Nov 30, 1992.
Pursuant to a congressional request, GAO determined whether the National Aeronautics and Space Administration (NASA) implemented an advisory committee's recommendation to strengthen its independent cost estimating capability.GAO found that: (1) NASA actions to implement an independent cost estimating function did not meet the intent of the committee's recommendation; (2) NASA reported results of f...
Further Evaluation of the Proposed Interim Consolidation of the Nuclear Regulatory Commission
EMD-81-76: Published: Jun 24, 1981. Publicly Released: Jun 24, 1981.
GAO was requested to respond to questions on the proposed interim consolidation of the Nuclear Regulatory Commission (NRC). These questions sought additional information and further explanation of matters discussed in a prior report.GAO concluded that both interim consolidation options could help strengthen NRC. Key factors have changed in favor of the proposed interim consolidation: (1) General S...
