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...
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'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 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 Acquisitions: Committing Prematurely to the Transformational Satellite Program Elevates Risks for Poor Cost, Schedule, and Performance Outcomes
GAO-04-71R: Published: Dec 4, 2003. Publicly Released: Dec 4, 2003.
In a multibillion-dollar effort, the Department of Defense (DOD) plans to build a space-based communications system that leverages technologies never before used in space. Such a system would enable DOD to transform how information is collected on potential U.S. adversaries and how military forces are warned of hostile action. The backbone of this system will be the Transformational Satellite (TSA...
Space Surveillance: DOD and NASA Need Consolidated Requirements and a Coordinated Plan
NSIAD-98-42: Published: Dec 1, 1997. Publicly Released: Dec 1, 1997.
GAO reviewed the Department of Defense's (DOD) and the National Aeronautics and Space Administration's (NASA) space surveillance requirements and DOD's space surveillance capabilities, focusing on: (1) how well DOD's existing surveillance capabilities support DOD's and NASA's current and future surveillance requirements; and (2) the extent to which potential surveillance capabilities and technolog...
