Space Acquisitions: Improvements Needed in Space Systems Acquisitions and Keys to Achieving Them
GAO-06-626T: Published: Apr 6, 2006. Publicly Released: Apr 6, 2006.
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. GAO was asked to testify on its findings on space acquisition problems and steps needed to improve outcomes.DOD's space acquisition programs continue to face substantial co...
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...
Space Acquisitions: Stronger Development Practices and Investment Planning Needed to Address Continuing Problems
GAO-05-891T: Published: Jul 12, 2005. Publicly Released: Jul 12, 2005.
GAO was asked to testify on problems relating to the Department of Defense's (DOD) space system acquisitions. In doing so, we drew on our previous reports related to the causes of acquisition problems, underlying incentives and pressures, and potential solutions.Our work on the acquisition of space-based capabilities over the last several years has been conducted on two levels. First, we have revi...
NASA: More Knowledge Needed to Determine Best Alternatives to Provide Space Station Logistics Support
GAO-05-488: Published: May 18, 2005. Publicly Released: May 31, 2005.
The National Aeronautics and Space Administration's (NASA) space shuttle fleet has been key to International Space Station operations. Since the grounding of the fleet in February 2003, Russia has provided logistics support. However, due to the limited payload capacity of the Russian space vehicles, on-orbit assembly of the space station stopped. In May 2004 and in February 2005, NASA testified be...
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...
Defense Space Activities: Continuation of Evolved Expendable Launch Vehicle Program's Progress to Date Subject to Some Uncertainty
GAO-04-778R: Published: Jun 24, 2004. Publicly Released: Jun 24, 2004.
The U.S. space policy states that access to and use of space is critical to preserving peace and protecting U.S. national security and also benefits the country's civil and commercial interests. Air Force guidance explains further that access to space requires the ability to launch critical space assets, when needed, by a mix of space launch systems from standard launch pads at major support facil...
Space Station: Status of Efforts to Determine Commercial Potential
NSIAD-99-153R: Published: Jun 30, 1999. Publicly Released: Jul 15, 1999.
Pursuant to a congressional request, GAO provided information on whether space-station-related commercial activities could generate revenue capable of reducing the station's annual cost of operations, which the National Aeronautics and Space Administration (NASA) estimates will average $1.3 billion, or $13 billion over a 10-year mission life after the space station is fully assembled in 2004.GAO n...
Space Station: U.S. Life-Cycle Funding Requirements
T-NSIAD-98-212: Published: Jun 24, 1998. Publicly Released: Jun 24, 1998.
GAO discussed U.S. funding requirements for the National Aeronautics and Space Administration's (NASA) International Space Station program, focusing on the station's development, assembly, and operation costs. GAO also: (1) compared the current cost estimate with the estimate in its June 1995 report; and (2) provided information on potential cost increases, current program reserves, the prime cont...
