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...
NASA's James Webb Space Telescope: Knowledge-Based Acquisition Approach Key to Addressing Program Challenges
GAO-06-634: Published: Jul 14, 2006. Publicly Released: Jul 14, 2006.
The National Aeronautics and Space Administration's (NASA) James Webb Space Telescope (JWST) is being designed to explore the origins and nature of the universe. It should allow scientists to look deeper into space--and thus farther back in time--than ever before. The program, however, has experienced cost growth of more than $1 billion and its schedule has slipped nearly 2 years. NASA recently re...
Defense Acquisitions: Space System Acquisition Risks and Keys to Addressing Them
GAO-06-776R: Published: Jun 1, 2006. Publicly Released: Jun 1, 2006.
On April 6, 2006, we testified before Congress on the Department of Defense's (DOD) space acquisitions. In fiscal year 2007, DOD expects to spend nearly $7 billion to acquire space-based capabilities to support current military and other government operations as well as to enable DOD to transform the way it collects and disseminates information, gathers data on its adversaries, and attacks targets...
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...
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...
Space Station: Cost to Operate After Assembly is Uncertain
NSIAD-99-177: Published: Aug 6, 1999. Publicly Released: Aug 18, 1999.
Pursuant to a congressional request, GAO reviewed the National Aeronautics and Space Administration's (NASA) estimate for the cost to operate the International Space Station after assembly is completed, focusing on: (1) whether any space station-related costs are not included in NASA's estimate; (2) the level of uncertainty in the cost estimate for operations, especially with regard to the potenti...
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...
