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: 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...
NASA: Implementing a Knowledge-Based Acquisition Framework Could Lead to Better Investment Decisions and Project Outcomes
GAO-06-218: Published: Dec 21, 2005. Publicly Released: Jan 23, 2006.
The National Aeronautics and Space Administration (NASA) plans to spend over $100 billion on capabilities and technologies to achieve the initial goals of the President's 2004 Vision for Space Exploration. In the past, NASA has had difficulty meeting cost, schedule, and performance objectives for some of its projects because it failed to adequately define project requirements and quantify resource...
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...
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 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 Shuttle: Further Improvements Needed in NASA's Modernization Efforts
GAO-04-203: Published: Jan 15, 2004. Publicly Released: Feb 13, 2004.
The Columbia tragedy has accentuated the need to modernize the 20-year-old space shuttle, the only U.S. launch system that carries people to and from space. The shuttle will now be needed for another two decades. As it ages, the spacecraft's components will also age, and it may become increasingly unreliable. GAO examined the National Aeronautics and Space Administration's (NASA) plans to upgrade...
Space Station: Impact of the Grounding of the Shuttle Fleet
GAO-03-1107: Published: Sep 12, 2003. Publicly Released: Oct 14, 2003.
In 1998, the National Aeronautics and Space Administration (NASA) and its international partners--Canada, Europe, Japan, and Russia--began on-orbit assembly of the International Space Station, envisioned as a permanently orbiting laboratory for conducting scientific research under nearly weightless conditions. Since its inception, the program has experienced numerous problems, resulting in signifi...
