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...
NASA's Deep Space Network: Current Management Structure Is Not Conducive to Effectively Matching Resources with Future Requirements
GAO-06-445: Published: Apr 27, 2006. Publicly Released: May 22, 2006.
The President's Vision for Space Exploration calls for human and robotic missions to the Moon, Mars, and beyond. In response, over the next two decades, NASA may spend $100 billion on new technologies and facilities that will require reliable ground communications to achieve those missions. Presently, that communications capability is provided by NASA's Deep Space Network--a system of antennas loc...
Space Acquisitions: DOD Needs a Departmentwide Strategy for Pursuing Low-Cost, Responsive Tactical Space Capabilities
GAO-06-449: Published: Mar 14, 2006. Publicly Released: Mar 14, 2006.
For more than two decades, the Department of Defense (DOD) has invested heavily in space assets to provide the warfighter with mission-critical information. Despite these investments, DOD commanders have reported shortfalls in space capabilities. To provide tactical capabilities to the warfighter sooner, DOD recently began developing TacSats--a series of small satellites intended to be built withi...
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...
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...
Observations on the National Aeronautics and Space Administration's Fiscal Year 1999 Performance Report and Fiscal Year 2001 Performance Plan
NSIAD-00-192R: Published: Jun 30, 2000. Publicly Released: Aug 1, 2000.
Pursuant to a congressional request, GAO reviewed the National Aeronautics and Space Administration's (NASA) fiscal year (FY) 1999 performance report and FY 2001 performance plan required by the Government Performance and Results Act of 1993.GAO noted that: (1) NASA made progress in meeting its FY 1999 performance targets for the three key agency outcomes included in GAO's assessment; (2) however,...
Advanced Solid Rocket Motor Status
NSIAD-93-258R: Published: Aug 13, 1993. Publicly Released: Aug 13, 1993.
Pursuant to a congressional request, GAO provided information on the status of the National Aeronautics and Space Administration's (NASA) Advanced Solid Rocket Motor Program. GAO noted that: (1) the need for the advanced motor has diminished since the development program was first approved in 1988; (2) NASA had no actual flight experience with the advanced motors when the program was approved; (3)...
Space Projects: Improvements Needed in Selecting Future Projects for Private Financing
NSIAD-90-147: Published: Sep 21, 1990. Publicly Released: Sep 21, 1990.
GAO assessed the National Aeronautics and Space Administration's (NASA) efforts to find acceptable private financing sources for seven space projects.GAO found that: (1) the Office of Management and Budget (OMB) and NASA selected and removed six of the seven projects selected from the NASA budget request before adequately evaluating their suitability for commercialization; (2) commercial aerospace...
Investment in Foreign Aerospace Vehicle Research and Technological Development Efforts
T-NSIAD-89-43: Published: Aug 2, 1989. Publicly Released: Aug 2, 1989.
GAO discussed foreign countries' aerospace goals and objectives, current aerospace vehicle programs, technological challenges, testing, and prospects for international cooperation. GAO found that: (1) foreign countries developed technologies for various concepts of operational aerospace vehicles to secure independent access to space, reduce launching costs, and ensure a competitive role in future...
