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: 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...
Space Shuttle: Status of NASA's Efforts to Address Workforce Issues Related to the Space Shuttle's Retirement
GAO-05-718T: Published: May 18, 2005. Publicly Released: May 18, 2005.
The National Aeronautics and Space Administration's (NASA) space shuttle program is key to implementing the President's vision for space exploration, which calls for completing the assembly of the International Space Station (ISS) by the end of the decade. Currently, the space shuttle, which is to be retired after ISS assembly is completed, is the only launch system capable of transporting ISS com...
Space Shuttle: Actions Needed to Better Position NASA to Sustain Its Workforce Through Retirement
GAO-05-230: Published: Mar 9, 2005. Publicly Released: Mar 24, 2005.
The President's vision for space exploration (Vision) directs the National Aeronautics and Space Administration (NASA) to retire the space shuttle following completion of the International Space Station, planned for the end of the decade. The retirement process will last several years and impact thousands of critically skilled NASA civil service and contractor employees that support the program. K...
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...
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...
