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...
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...
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...
