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: Key Management and Program Challenges
GAO-10-387T: Published: Feb 3, 2010. Publicly Released: Feb 3, 2010.
The National Aeronautics and Space Administration (NASA) is in the midst of many changes and one of the most challenging periods in its history. The space shuttle is slated to retire this year, the International Space Station nears completion but remains underutilized, and a new means of human space flight is under development. Most recently, the administration has proposed a new direction for 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: Commercial Partners Are Making Progress, but Face Aggressive Schedules to Demonstrate Critical Space Station Cargo Transport Capabilities
GAO-09-618: Published: Jun 16, 2009. Publicly Released: Jun 16, 2009.
After the planned retirement of the space shuttle in 2010, the National Aeronautics and Space Administration (NASA) will face a cargo resupply shortfall for the International Space Station of approximately 40 metric tons between 2010 and 2015. NASA budgeted $500 million in seed money to commercial partners to develop new cargo transport capabilities through its Commercial Orbital Transportation Se...
Space Acquisitions: DOD's Goals for Resolving Space Based Infrared System Software Problems Are Ambitious
GAO-08-1073: Published: Sep 30, 2008. Publicly Released: Sep 30, 2008.
In 1996, DOD initiated the Space Based Infrared System (SBIRS) to replace the nation's current missile detection system, and to provide expanded missile warning capability. Since then, SBIRS has been restructured several times to stem cost increases and schedule delays, including revising program goals in 2002, 2004, and 2005. These actions were partly due to the challenges of developing sophistic...
Space Acquisitions: Uncertainties in the Evolved Expendable Launch Vehicle Program Pose Management and Oversight Challenges
GAO-08-1039: Published: Sep 26, 2008. Publicly Released: Sep 26, 2008.
The Department of Defense (DOD) plans to spend over $27 billion acquiring launch services through the Evolved Expendable Launch Vehicle (EELV) program over the next 12 years. The EELV program uses two families of commercially owned and operated vehicles to launch satellites. Partly because the commercial space market did not develop as expected, the EELV program has undergone significant changes....
Space Acquisitions: Actions Needed to Expand and Sustain Use of Best Practices
GAO-07-730T: Published: Apr 19, 2007. Publicly Released: Apr 19, 2007.
DOD's space system acquisitions have experienced problems over the past several decades that have driven up costs by hundreds of millions, even billions of dollars, stretched schedules by years, and increased performance risks. DOD has recognized the need to change its approach to developing space systems and is attempting to instill best practices in new efforts. GAO was asked to testify on its f...
NASA: Issues Surrounding the Transition from the Space Shuttle to the Next Generation of Human Space Flight Systems
GAO-07-595T: Published: Mar 28, 2007. Publicly Released: Mar 28, 2007.
On January 14, 2004, the President announced a new Vision for space exploration that directs the National Aeronautics and Space Administration (NASA) to focus its efforts on returning humans to the moon by 2020 in preparation for future, more ambitions missions. Implementing the Vision will require hundreds of billions of dollars and a sustained commitment from multiple administrations and Congres...
Space Acquisitions: DOD Needs to Take More Action to Address Unrealistic Initial Cost Estimates of Space Systems
GAO-07-96: Published: Nov 17, 2006. Publicly Released: Nov 17, 2006.
Estimated costs for the Department of Defense's (DOD) major space acquisition programs have increased by about $12.2 billion from initial estimates for fiscal years 2006 through 2011. Cost growth for ongoing Air Force programs above initial estimates accounts for a substantial portion of this 44 percent increase. In light of the role that optimistic estimating is believed to have played in exacerb...
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...
