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'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...
Technology Development: New DOD Space Science and Technology Strategy Provides Basis for Optimizing Investments, but Future Versions Need to Be More Robust
GAO-05-155: Published: Jan 28, 2005. Publicly Released: Jan 28, 2005.
The Department of Defense (DOD) is depending heavily on new space-based technologies to support and transform future military operations. Yet there are concerns that efforts to develop technologies for space systems are not tied to strategic goals for space and are not well planned or coordinated. In the National Defense Authorization Act for 2004, the Congress required DOD to develop a space scie...
Space Acquisitions: Committing Prematurely to the Transformational Satellite Program Elevates Risks for Poor Cost, Schedule, and Performance Outcomes
GAO-04-71R: Published: Dec 4, 2003. Publicly Released: Dec 4, 2003.
In a multibillion-dollar effort, the Department of Defense (DOD) plans to build a space-based communications system that leverages technologies never before used in space. Such a system would enable DOD to transform how information is collected on potential U.S. adversaries and how military forces are warned of hostile action. The backbone of this system will be the Transformational Satellite (TSA...
Space Transportation: Challenges Facing NASA's Space Launch Initiative
GAO-02-1020: Published: Sep 17, 2002. Publicly Released: Oct 2, 2002.
In 2001, the National Aeronautics and Space Administration (NASA) began undertaking a new effort--the Space Launch Initiative (SLI)--to develop a new generation of space transportation vehicles. SLI is expected to result in development of the second generation of reusable launch vehicles, the space shuttle being the first generation. NASA plans to define basic requirements for its second-generatio...
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...
Defense Space Activities: Status of Reorganization
GAO-02-772R: Published: Jun 26, 2002. Publicly Released: Jun 26, 2002.
To meet long-standing concerns about the Department of Defense's (DOD) organization and management of national security space activities, Congress chartered the Commission to Assess United States National Security Space Management and Organization to study the organization and management of space activities that support U.S. national security interests and make recommendations for improvements. DO...
NASA: International Space Station and Shuttle Support Cost Limits
GAO-01-1000R: Published: Aug 31, 2001. Publicly Released: Aug 31, 2001.
The National Aeronautics and Space Administration (NASA) Authorization Act for Fiscal Year 2000 set cost limits on the international space station and space shuttle programs. Under the act, NASA may not obligate more than $25 billion for space station development or more than $17.7 billion for shuttle launches in connection with space station assembly. The act also stipulates that for the purpose...
NASA: Status of Achieving Key Outcomes and Addressing Major Management Challenges
GAO-01-868: Published: Jul 31, 2001. Publicly Released: Jul 31, 2001.
GAO reviewed the National Aeronautics and Space Administration's (NASA) fiscal year 2000 performance report to assess the agency's progress in achieving selected key outcomes important to NASA's mission. The selected key outcomes are to (1) expand scientific knowledge of the Earth system, (2) expand the commercial development of space, and (3) deploy and operate the International Space Station saf...
