The U.S. aviation industry, airline passengers, aircraft pilots, airports, and airline companies are all facing challenges. The air transportation system is experiencing unprecedented and increasing levels of use. The federal government understands the critical need to update the U.S. air transportation system, and plans to implement the Next Generation Air Transportation System (NextGen) by 2025. This system is an example of active networking...

To meet the objectives of the Vision for Space Exploration (VSE), NASA must develop a wide array of enabling technologies. For this purpose, NASA established the Exploration Technology Development Program (ETDP). Currently, ETDP has 22 projects underway. In the report accompanying the House-passed version of the FY2007 appropriations bill, the agency was directed to request from the NRC an independent assessment of the ETDP. This interim repor...

The Vision for Space Exploration (VSE) announced by President George W. Bush in 2004 sets NASA and the nation on a bold path to return to the Moon and one day put a human on Mars. The long-term endeavor represented by the VSE is, however, subject to the constraints imposed by annual funding. Given that the VSE may take tens of years to implement, a significant issue is whether NASA and the United States will have the workforce needed to achiev...

The U.S. air transportation system is very important for our economic well-being and national security. The nation is also the global leader in civil and military aeronautics, a position that needs to be maintained to help assure a strong future for the domestic and international air transportation system. Strong action is needed, however, to ensure that leadership role continues. To that end, the Congress and NASA requested the NRC to underta...

In 2003, Congress directed the Secretary of Transportation to establish the Next Generation Air Transportation System (NGATS) Joint Planning and Development Office (JDPO) to plan the development of an air transportation system capable of meeting potential air traffic demand for 2025. All federal agencies involved in aviation participate in the JDPO providing the opportunity overcome many of the major barriers to developing an effective NGATS. ...

NASA's Human Exploration and Development of Space (HEDS) program within the Office of Space Flight has proposed a new framework for space technology and systems development?Advanced Systems, Technology, Research, and Analysis (ASTRA) for future space flight capabilities. To assist in the development of this framework, NASA asked the National Research Council to convene a series of workshops on technology policy issues concerning the relationsh...

Ever since the completion of the Apollo program, there has been a lack of consensus about the future of human spaceflight. The Columbia tragedy in February 2003 rekindled public debate about this question. In November 2003, the Space Studies Board and the Aeronautics and Space Engineering Board organized a workshop to explore aspects of the question, what should be the principal purpose, goals, and priorities of the U.S. civil space program? T...

The National Research Council (NRC) of the National Academies was asked by NASA and the Office of Management and Budget to perform an assessment of NASA's Aerospace Technology Enterprise. The first such review, which began in early 2002, examined Pioneering Revolutionary Technology (now known as Mission and Science Measurement Technology). The assessment presented here, of the Aeronautics Technology Programs, began in early 2003 and is the sec...

The Committee for the Review of NASA's Pioneering Revolutionary Technology (PRT) Program and its three supporting panels were charged by the National Aeronautics and Space Administration (NASA) with assessing the overall scientific and technical quality of the PRT program and its component programs, along with their associated elements and individual research tasks. Major issues addressed in the review include (1) research portfolios, (2) rese...

Each new generation of commercial aircraft produces less noise and fewer emissions per passenger-kilometer (or ton-kilometer of cargo) than the previous generation. However, the demand for air transportation services grows so quickly that total aircraft noise and emissions continue to increase. Meanwhile, federal, state, and local noise and air quality standards in the United States and overseas have become more stringent. It is becoming more ...

This report evaluates the Defense Threat Reduction Agency prior and present sponsored efforts, assess the present state of the art in thermionic energy conversion systems, assess the technical challenges to the development of viable thermionic energy conversion systems for both space and terrestrial applications, and recommend a prioritized set of objectives for a future research and development program for advanced thermionic systems for spac...

High-speed flight is a major technological challenge for both commercial and business aviation. As a first step in revitalizing efforts by the National Aeronautics and Space Administration (NASA) to achieve the technology objective of high-speed air travel, NASA requested the National Research Council (NRC) to conduct a study that would identify approaches for achieving breakthroughs in research and technology for commercial supersonic aircraf...

In the five decades since NASA was created, the agency has sustained its legacy from the National Advisory Committee on Aeronautics (NACA) in playing a major role in U.S. aeronautics research and has contributed substantially to United States preeminence in civil and military aviation. This preeminence has contributed significantly to the overall economy and balance of trade of the United States through the sales of aircraft throughout the wor...

The Space Communications Office (SCO) at NASA has two primary roles. The first is to manage two of the communications networks that enable spaceflight operations and research, and the second is to integrate agency-wide telecommunications issues. In 2005, NASA asked the NRC to review the effectiveness of the SCO in carrying out its responsibilities by assessing the overall quality of the space communications program. This report presents a revi...

In January 2006, the President announced a civilian space policy focusing on exploration. This book provides a review of the workforce implications of NASA's plans, an assessment of science and technology workforce demographics, an analysis of factors affecting the aerospace workforce for both NASA and the relevant aerospace industry, and more.

For the National Aeronautics and Space Administration (NASA) to achieve many of its space science and exploration goals over the next several decades, dramatic advances in space technology will be necessary. NASA has developed a set of 14 draft roadmaps to guide the development of such technologies under the leadership of the NASA Office of the Chief Technologist (OCT). Each roadmap focuses on a particular technology area. OCT requested that t...

In response to requests from Congress, NASA asked the National Research Council to undertake a decadal survey of life and physical sciences in microgravity. Developed in consultation with members of the life and physical sciences communities, the guiding principle for the study is to set an agenda for research for the next decade that will allow the use of the space environment to solve complex problems in life and physical sciences so as to d...

The NASA Institute for Advanced Concepts (NIAC) was formed in 1998 to provide an independent source of advanced aeronautical and space concepts that could dramatically impact how NASA develops and conducts its missions. Until the program's termination in August 2007, NIAC provided an independent open forum, a high-level point of entry to NASA for an external community of innovators, and an external capability for analysis and definition of adv...

In 2006, the NRC published a Decadal Survey of Civil Aeronautics: Foundation for the Future, which set out six strategic objectives for the next decade of civil aeronautics research and technology. To determine how NASA is implementing the decadal survey, Congress mandated in the National Aeronautics and Space Administration Act of 2005 that the NRC carry out a review of those efforts. Among other things, this report presents an assessment of ...
