Perchlorate: Occurrence Is Widespread but at Varying Levels; Federal Agencies Have Taken Some Actions to Respond to and Lessen Releases
GAO-10-769: Published: Aug 12, 2010. Publicly Released: Sep 13, 2010.
Perchlorate is both a man-made and naturally occurring chemical. It is used in rocket fuel, explosives, fireworks, and other products. Naturally occurring perchlorate is produced through atmospheric processes and then settles on surface water or land. Perchlorate can disrupt the uptake of iodide in the thyroid, potentially interfering with thyroid function and negatively affecting fetal and infant...
Next Generation Air Transportation System: FAA and NASA Have Improved Human Factors Research Coordination, but Stronger Leadership Needed
GAO-10-824: Published: Aug 6, 2010. Publicly Released: Aug 6, 2010.
To address challenges to the aviation industry's economic health and safety, the Federal Aviation Administration (FAA) is collaborating with the National Aeronautics and Space Administration (NASA) and other federal partners to plan and implement the Next Generation Air Transportation System (NextGen). NextGen will transform the current radar-based air traffic control system into a satellite-based...
Polar-Orbiting Environmental Satellites: Agencies Must Act Quickly to Address Risks That Jeopardize the Continuity of Weather and Climate Data
GAO-10-558: Published: May 27, 2010. Publicly Released: Jun 29, 2010.
In the 8 years since a contract was awarded, the National Polar-orbiting Operational Environmental Satellite System (NPOESS)--a tri-agency program managed by the National Oceanic and Atmospheric Administration (NOAA), the Department of Defense (DOD), and the National Aeronautics and Space Administration (NASA)--has experienced escalating costs, schedule delays, and ineffective interagency manageme...
Environmental Satellites: Planning Required to Mitigate Near-term Risks and Ensure Long-term Continuity
GAO-10-858T: Published: Jun 29, 2010. Publicly Released: Jun 29, 2010.
Environmental satellites provide data used for weather forecasting, measuring variations in climate over time, and predicting space weather. Due to the continuing cost, schedule, and tri-agency management challenges of the National Polar-orbiting Operational Environmental Satellite System (NPOESS)--a key satellite acquisition managed by the National Oceanic and Atmospheric Association (NOAA), the...
Campaign Finance Reform: Additional Information Related to Program Goals in Two States Offering Full Public Funding for Political Candidates (GAO-10-391SP), an E-supplement to GAO-10-390

In 2003, GAO reviewed the public financing programs in Maine and Arizona and found the programs' goals were to (1) increase electoral competition; (2) increase voter choice; (3) curb increases in campaign co...
Environmental Satellites: Strategy Needed to Sustain Critical Climate and Space Weather Measurements
GAO-10-456: Published: Apr 27, 2010. Publicly Released: May 27, 2010.
Environmental satellites provide data on the earth and its space environment that are used for forecasting the weather, measuring variations in climate over time, and predicting space weather. In planning for the next generation of these satellites, federal agencies originally sought to fulfill weather, climate, and space weather requirements. However, in 2006, federal agencies restructured two ke...
Helium Program: Key Developments Since the Early 1990s and Future Considerations
GAO-10-700T: Published: May 13, 2010. Publicly Released: May 13, 2010.
The federal government has been extensively involved in the production, storage, and use of helium since the early part of the 20th Century. The federal helium program is currently managed by the Department of the Interior's Bureau of Land Management (BLM). During the 1960s and early 1970s, Interior purchased about 34 billion cubic feet of crude helium for conservation purposes and to meet federal...
Space Acquisitions: DOD Poised to Enhance Space Capabilities, but Persistent Challenges Remain in Developing Space Systems
GAO-10-447T: Published: Mar 10, 2010. Publicly Released: Mar 10, 2010.
The majority of large-scale acquisition programs in the Department of Defense's (DOD) space portfolio have experienced problems during the past two decades that have driven up costs by billions of dollars, stretched schedules by years, and increased technical risks.
