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...
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...
Space Station: Inadequate Planning and Design Led to Propulsion Module Project Failure
GAO-01-633: Published: Jun 20, 2001. Publicly Released: Jun 29, 2001.
This report discusses the National Aeronautics and Space Administration's (NASA) contract with Boeing Reusable Space Systems to build the now-canceled follow-on propulsion module for the International Space Station. GAO found that the initial propulsion module project did not meet performance, cost, and schedule goals largely because NASA proceeded with Boeing's proposal without following fundamen...
International Space Station: U.S. Life-Cycle Funding Requirements
NSIAD-98-147: Published: May 22, 1998. Publicly Released: Jun 1, 1998.
Pursuant to a congressional request, GAO reviewed issues associated with the National Aeronautics and Space Administration's (NASA) International Space Station program, focusing on: (1) estimates of the station's development, assembly, and operations costs and comparing this estimate with the estimate in GAO's June 1995 report; (2) program uncertainties that may affect those costs; (3) potential d...
National Space Issues: Observations on Defense Space Programs and Activities
NSIAD-94-253: Published: Aug 16, 1994. Publicly Released: Aug 16, 1994.
Pursuant to a congressional request, GAO reviewed the Department of Defense's (DOD) space programs and activities.GAO found that: (1) since 1989, the government's efforts to acquire a new space launch system have been unsuccessful; (2) the administration's current national space transportation strategy does not identify a mechanism for implementing high-level management within the Executive Office...
Military Space Programs: Comprehensive Analysis Needed and Cost Savings Available
T-NSIAD-94-164: Published: Apr 14, 1994. Publicly Released: Apr 14, 1994.
GAO discussed two Department of Defense (DOD) satellite programs. GAO noted that: (1) DOD has an opportunity to assess its needs for early missile warning information, since it cancelled the most recent follow-on program for its Defense Support Program (DSP) and replaced DSP with the Alert, Locate, and Report Missiles System (ALARM) which has more tactical emphasis; (2) DOD needs to review and val...
NASA: Major Challenges for Management
T-NSIAD-94-18: Published: Oct 6, 1993. Publicly Released: Oct 6, 1993.
GAO discussed management challenges facing the National Aeronautics and Space Administration (NASA), focusing on: (1) matching program goals with likely budgets; (2) managing systems development efforts more efficiently; (3) improving operations and oversight; and (4) preserving U.S. aeronautical leadership. GAO noted that: (1) NASA efforts to match its strategic plan with its budget have been ina...
