Space Shuttle: Actions Needed to Better Position NASA to Sustain Its Workforce Through Retirement
GAO-05-230: Published: Mar 9, 2005. Publicly Released: Mar 24, 2005.
The President's vision for space exploration (Vision) directs the National Aeronautics and Space Administration (NASA) to retire the space shuttle following completion of the International Space Station, planned for the end of the decade. The retirement process will last several years and impact thousands of critically skilled NASA civil service and contractor employees that support the program. K...
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...
NASA: Compliance with Cost Limits
GAO-04-648R: Published: Apr 2, 2004. Publicly Released: Apr 2, 2004.
Section 202 of the National Aeronautics and Space Administration (NASA) Authorization Act of 2000 (P.L. 106-391) requires that GAO verify NASA's accounting for amounts obligated against established limits for the space station and related space shuttle support. Under the act, obligations are limited to $25 billion for the space station and $17.7 billion for shuttle support.In the past, we reported...
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...
NASA: Shuttle Fleet's Safe Return to Flight Is Key to Space Station Progress
GAO-04-201T: Published: Oct 29, 2003. Publicly Released: Oct 29, 2003.
Since its inception, the International Space Station has experienced numerous problems that have resulted in significant cost growth and assembly schedule slippages. Following the Columbia accident and the subsequent grounding of the shuttle fleet in February 2003, concerns about the future of the space station escalated, as the fleet has been key to the station's assembly and operations. In Augus...
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...
Major Management Challenges and Program Risks: National Aeronautics and Space Administration
GAO-03-114: Published: Jan 1, 2003. Publicly Released: Jan 1, 2003.
In its 2001 performance and accountability report on NASA, GAO identified important management, oversight, and workforce issues facing the agency. The information GAO presents in this report is intended to help sustain congressional attention and an agency focus on continuing to make progress in addressing these challenges--and others that have arisen since 2001--and ultimately overcoming them. Th...
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...
