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 Shuttle: Costs for Hubble Servicing Mission and Implementation of Safety Recommendations Not Yet Definitive
GAO-05-34: Published: Nov 19, 2004. Publicly Released: Dec 17, 2004.
Hubble's continued operation has been dependent on manned servicing missions using the National Aeronautics and Space Administration's (NASA) shuttle fleet. The fleet was grounded in early 2003 following the loss of the Space Shuttle Columbia, as NASA focused its efforts on responding to recommendations made by the Columbia Accident Investigation Board (CAIB). In January 2004, NASA announced its d...
Polar-Orbiting Environmental Satellites: Information on Program Cost and Schedule Changes
GAO-04-1054: Published: Sep 30, 2004. Publicly Released: Sep 30, 2004.
Our nation's current operational polar-orbiting environmental satellite program is a complex infrastructure that includes two satellite systems, supporting ground stations, and four central data processing centers. 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...
NASA: Lack of Disciplined Cost-Estimating Processes Hinders Effective Program Management
GAO-04-642: Published: May 28, 2004. Publicly Released: Jun 22, 2004.
For more than a decade, GAO has identified the National Aeronautics and Space Administration's (NASA) contract management as a high-risk area--in part because of NASA's inability to collect, maintain, and report the full cost of its programs and projects. Lacking this information, NASA has been challenged to manage its programs and control program costs. The scientific and technical expectations i...
NASA: Shuttle Fleet's Safe Return to Flight Is Key to Space Station Progress
GAO-04-201T: Published: Oct 29, 2003. Publicly Released: Oct 29, 2003.
Since its inception, the International Space Station has experienced numerous problems that have resulted in significant cost growth and assembly schedule slippages. Following the Columbia accident and the subsequent grounding of the shuttle fleet in February 2003, concerns about the future of the space station escalated, as the fleet has been key to the station's assembly and operations. In Augus...
Opportunities for Oversight and Improved Use of Taxpayer Funds: Examples from Selected GAO Work
GAO-03-1006: Published: Aug 1, 2003. Publicly Released: Aug 1, 2003.
This report is submitted pursuant to section 301(e) of the Concurrent Resolution on the Budget for Fiscal Year 2004, which directs the Comptroller General to submit to the Committees on the Budget a comprehensive report identifying instances in which the committees of jurisdiction may make legislative changes to improve the economy, efficiency, and effectiveness of federal programs within their j...
Space Station: Actions Under Way to Manage Cost, but Significant Challenges Remain
GAO-02-735: Published: Jul 17, 2002. Publicly Released: Jul 18, 2002.
The National Aeronautics and Space Administration (NASA) revealed that the cost to complete assembly of the international space station has risen from $25 billion to $30 billion. Much of that cost growth is due to inadequate definition of requirements, changes in program content, schedule delays, and poor program oversight. Weaknesses in the program's cost-estimating process call into question the...
NASA's X-33 and X-34 Programs
GAO-01-1041R: Published: Aug 13, 2001. Publicly Released: Aug 13, 2001.
This report (1) reviews the usefulness of cooperative agreements as a National Aeronautics and Space Administration (NASA) contractual mechanism, (2) the reasons behind NASA's aggressive and rapid-style management of the X-33 and X-34 programs, (3) the timeliness of NASA's plans to generate adequate program cost estimates for gauging management reserves in the 15-20 percent range, and (4) the infl...
