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...
Environmental Satellites: Polar-orbiting Satellite Acquisition Faces Delays; Decisions Needed on Whether and How to Ensure Climate Data Continuity
GAO-08-899T: Published: Jun 19, 2008. Publicly Released: Jun 19, 2008.
The National Polar-orbiting Operational Environmental Satellite System (NPOESS) is a tri-agency acquisition--managed by the Department of Commerce's National Oceanic and Atmospheric Administration (NOAA), the Department of Defense (DOD), and the National Aeronautics and Space Administration (NASA)--which has experienced escalating costs, schedule delays, and technical difficulties. These factors l...
Space Acquisitions: DOD Is Making Progress to Rapidly Deliver Low Cost Space Capabilities, but Challenges Remain
GAO-08-516: Published: Apr 25, 2008. Publicly Released: Apr 25, 2008.
The Department of Defense (DOD) invests heavily in space assets to provide the warfighter with intelligence, navigation, and other information critical to conducting military operations. In fiscal year 2008 alone, DOD expects to spend over $22 billion dollars on space systems. Despite this investment, senior military commanders have reported shortfalls in tactical space capabilities in each recent...
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,...
Aviation and the Environment: FAA's and NASA's Research and Development Plans for Noise Reduction Are Aligned but the Prospects of Achieving Noise Reduction Goals Are Uncertain
GAO-08-384: Published: Feb 15, 2008. Publicly Released: Mar 17, 2008.
Reducing aviation noise is important to the efficient operation and expansion of the National Airspace System because community opposition to aviation noise is a major obstacle to airport and runway development. Such development is needed to help address congestion and meet the nation's rapidly growing demand for air travel. The Federal Aviation Administration (FAA) and the National Aeronautics an...
Space Based Infrared System High Program and its Alternative
GAO-07-1088R: Published: Sep 12, 2007. Publicly Released: Sep 12, 2007.
The U.S. relies on infrared satellites to provide early warning of enemy missile launches and protect the nation, its military forces, and allies. In 1996, the Department of Defense (DOD) initiated the Space Based Infrared System (SBIRS) program to replace the nation's current missile detection system and provide expanded capabilities to support intelligence, surveillance, and reconnaissance missi...
Business Modernization: NASA Must Consider Agencywide Needs to Reap the Full Benefits of Its Enterprise Management System Modernization Effort
GAO-07-691: Published: Jul 20, 2007. Publicly Released: Aug 20, 2007.
Since 1990, GAO has designated the National Aeronautics and Space Administration's (NASA) contract management as an area of high risk in part because it lacked modern systems to provide accurate and reliable information on contract spending. In April 2000, NASA began a system modernization effort, known as the Integrated Enterprise Management Program (IEMP). When GAO last reported on the status of...
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: Challenges in Completing and Sustaining the International Space Station
GAO-07-1121T: Published: Jul 24, 2007. Publicly Released: Jul 24, 2007.
This testimony discusses the challenges faced by the National Aeronautics and Space Administration (NASA) on the International Space Station (ISS) and the Space Shuttle. NASA is in the midst of one of the most challenging periods in its history. As part of its Vision for Space Exploration, NASA is simultaneously developing a range of new technologies and highly complex systems to support future ex...
Environmental Satellite Acquisitions: Progress and Challenges
GAO-07-1099T: Published: Jul 11, 2007. Publicly Released: Jul 11, 2007.
Environmental satellites provide data and imagery that are used by weather forecasters, climatologists, and the military to map and monitor changes in weather (including severe weather such as hurricanes), climate, the oceans, and the environment. Two current acquisitions are the $12.5 billion National Polar-orbiting Operational Environmental Satellite System (NPOESS) program--which is to replace...
