NASA: Ares I and Orion Project Risks and Key Indicators to Measure Progress
GAO-08-186T: Published: Apr 3, 2008. Publicly Released: Apr 3, 2008.
The National Aeronautics and Space Administration (NASA) is in the midst of two new development efforts as part of the Constellation Program--the Ares I Crew Launch Vehicle and the Orion Crew Exploration Vehicle. These projects are critical to the success of the overall program, which will return humans to spaceflight after Space Shuttle retirement in 2010. To reduce the gap in human spaceflight,...
NASA Supplier Base: Challenges Exist in Transitioning from the Space Shuttle Program to the Next Generation of Human Space Flight Systems
GAO-07-940: Published: Jul 25, 2007. Publicly Released: Jul 25, 2007.
The Space Shuttle Program is currently supported by over 1,500 active suppliers, some of whom are the only known or certified source of a particular material, part or service. The retirement of the Shuttle and transition to planned exploration activities, as called for in the President's Vision for Space Exploration, creates the need for NASA to begin making decisions today about its supplier base...
NASA: Sound Management and Oversight Key to Addressing Crew Exploration Vehicle Project Risks
GAO-06-1127T: Published: Sep 28, 2006. Publicly Released: Sep 28, 2006.
The National Aeronautics and Space Administration (NASA) plans to spend nearly $230 billion over the next two decades implementing the President's Vision for Space Exploration (Vision) plans. In July 2006, GAO issued a report that questioned the program's affordability, and particularly, NASA's acquisition approach for one of the program's major projects--the Crew Exploration Vehicle (CEV). This t...
NASA: Long-Term Commitment to and Investment in Space Exploration Program Requires More Knowledge
GAO-06-817R: Published: Jul 17, 2006. Publicly Released: Jul 26, 2006.
The National Aeronautics and Space Administration (NASA) plans to spend nearly $230 billion over the next two decades implementing the Vision for Space Exploration. In January 2006, NASA publicly released its Exploration Systems Architecture Study (ESAS), which is an effort to identify the best architecture and strategy to implement the President's 2004 Vision for Space Exploration (Vision). The c...
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...
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...
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...
NASA's X-33 and X-34 Programs
GAO-01-1041R: Published: Aug 13, 2001. Publicly Released: Aug 13, 2001.
This report (1) reviews the usefulness of cooperative agreements as a National Aeronautics and Space Administration (NASA) contractual mechanism, (2) the reasons behind NASA's aggressive and rapid-style management of the X-33 and X-34 programs, (3) the timeliness of NASA's plans to generate adequate program cost estimates for gauging management reserves in the 15-20 percent range, and (4) the infl...
Space Station: Inadequate Planning and Design Led to Propulsion Module Project Failure
GAO-01-633: Published: Jun 20, 2001. Publicly Released: Jun 29, 2001.
This report discusses the National Aeronautics and Space Administration's (NASA) contract with Boeing Reusable Space Systems to build the now-canceled follow-on propulsion module for the International Space Station. GAO found that the initial propulsion module project did not meet performance, cost, and schedule goals largely because NASA proceeded with Boeing's proposal without following fundamen...
