NASA: Challenges in Completing and Sustaining the International Space Station
GAO-08-581T: Published: Apr 24, 2008. Publicly Released: Apr 24, 2008.
The International Space Station (ISS), the most complex scientific space project ever attempted, remains incomplete. NASA expects the station's final construction cost will be $31 billion and expects sustainment costs through the station's planned retirement in fiscal year 2016 to total $11 billion. The space shuttle, the only vehicle capable of transporting large segments of the station into orbi...
NASA: Progress Made on Strategic Human Capital Management, but Future Program Challenges Remain
GAO-07-1004: Published: Aug 8, 2007. Publicly Released: Aug 8, 2007.
The National Aeronautics and Space Administration (NASA) is engaged in efforts to replace the Space Shuttle with the next generation of human space flight systems and implement the President's space exploration policy. To do this, NASA must recruit, develop, and retain certain critical skills in its workforce, guided by its strategic human capital management plan. GAO was asked to examine the exte...
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...
U.S. Aerospace Industry: Progress in Implementing Aerospace Commission Recommendations, and Remaining Challenges
GAO-06-920: Published: Sep 13, 2006. Publicly Released: Sep 28, 2006.
The U.S. aerospace industry's wide-ranging activities--including commercial aviation, national security, and space exploration--make it critical to the economic health and strategic strength of our nation. However, the industry faces challenges, such as a national air traffic management system that, in its present form, cannot handle expected increases in demand; an aging aerospace workforce; and...
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...
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 Deep Space Network: Current Management Structure Is Not Conducive to Effectively Matching Resources with Future Requirements
GAO-06-445: Published: Apr 27, 2006. Publicly Released: May 22, 2006.
The President's Vision for Space Exploration calls for human and robotic missions to the Moon, Mars, and beyond. In response, over the next two decades, NASA may spend $100 billion on new technologies and facilities that will require reliable ground communications to achieve those missions. Presently, that communications capability is provided by NASA's Deep Space Network--a system of antennas loc...
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 Transportation: Challenges Facing NASA's Space Launch Initiative
GAO-02-1020: Published: Sep 17, 2002. Publicly Released: Oct 2, 2002.
In 2001, the National Aeronautics and Space Administration (NASA) began undertaking a new effort--the Space Launch Initiative (SLI)--to develop a new generation of space transportation vehicles. SLI is expected to result in development of the second generation of reusable launch vehicles, the space shuttle being the first generation. NASA plans to define basic requirements for its second-generatio...
Defense Space Activities: Status of Reorganization
GAO-02-772R: Published: Jun 26, 2002. Publicly Released: Jun 26, 2002.
To meet long-standing concerns about the Department of Defense's (DOD) organization and management of national security space activities, Congress chartered the Commission to Assess United States National Security Space Management and Organization to study the organization and management of space activities that support U.S. national security interests and make recommendations for improvements. DO...
