Commercial Launch Vehicles: NASA Taking Measures to Manage Delays and Risks
GAO-11-692T: Published: May 26, 2011. Publicly Released: May 26, 2011.
Since the National Aeronautics and Space Administration (NASA) created the strategy for the Commercial Orbital Transportation Services (COTS) project in 2005, the space landscape has changed significantly--the Space Shuttle program is retiring and the Ares I will not be available--increasing the importance of the timely development of COTS vehicles. The lack of alternatives for supplying the Inter...
International Space Station: Significant Challenges May Limit Onboard Research
GAO-10-9: Published: Nov 25, 2009. Publicly Released: Dec 22, 2009.
In 2010, after about 25 years of work and the expenditure of billions of dollars, the International Space Station (ISS) will be completed. According to the National Aeronautics and Space Administration (NASA), the ISS crew will then be able to redirect its efforts from assembling the station to conducting research. In 2005, Congress designated the ISS as a national laboratory; in addition, the NAS...
NASA: Briefing on National Aeronautics and Space Administration's Programs and Associated Activities
GAO-10-87R: Published: Oct 15, 2009. Publicly Released: Oct 15, 2009.
The National Aeronautics and Space Act of 1958, as amended, established the National Aeronautics and Space Administration (NASA) as the civilian agency that exercises control over U.S. aeronautical and space activities and seeks and encourages the fullest commercial use of space. NASA's activities span a broad range of complex and technical endeavors, from investigating the composition, evaluation...
NASA: Agency Has Taken Steps Toward Making Sound Investment Decisions for Ares I but Still Faces Challenging Knowledge Gaps
GAO-08-51: Published: Oct 31, 2007. Publicly Released: Nov 29, 2007.
One of the first steps in the National Aeronautics and Space Administration's (NASA) efforts to implement the President's plan to return humans to the moon and prepare for eventual human space flight to Mars is the development of the Ares I Crew Launch Vehicle. In 2005, NASA outlined a framework for implementing the President's plan and has awarded contracts for Ares I and the Orion Crew Explorati...
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: 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: 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...
