Book excerpt: NASA's detailed programmatic goals, system architectures, and mission designs for future human spaceflight beyond Earth orbit remain unspecified. Given this uncertainty, it is not clear exactly which technologies are necessary for enabling future exploration. The process of establishing technology development strategy relies on methods to evaluate the benefits and cost of potential investments. While the cost of technology development is often the primary uncertainty, in this application it is particularly difficult to quantify the benefit of technology development without a clear understanding of the system architecture to which it is being applied. With destinations and exploration strategy left to be determined, the potential benefits of any given technology can not be stated with certainty. While challenging, it is necessary to identify a prioritization of these development projects for early investment before the system architecture is defined. This thesis develops a framework for evaluating technologies in the context of long term system architecture planning for the future human space exploration transportation system. An abstracted solution-neutral formulation of the transportation architecture to any arbitrary destination is defined as a combination of multiple architectural sub-problems. To evaluate technologies within the tradespace, two measures are adapted from design of experiments literature. Main effects analysis is used as a measure of a technology's influence on the best architectures. Similarly, the strength of coupling effects between two technologies is captured by interaction effects. The measures of technology influence and coupling enable architects to prioritize technologies based on their performance, and to organize investment decisions by those that must be treated together and those that can be taken in parallel. The system architecture tradespace for Mars, the Moon, and two representative Near-Earth Asteroid (NEA) missions are explored and presented. Results from the proposed influence and coupling measures are used to evaluate technologies considered in the tradespace and to understand the benefits and tradeoffs presented by investing in different technologies in relation to each destination. Following the results from each tradespace, some suggestions of favorable pre-cursor missions to the Moon or NEAs are proposed as preparation for a future Mars exploration mission.

Download or read book Lunar Outpost written by Erik Seedhouse and published by Springer Science & Business Media. This book was released on 2009-04-22 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lunar Outpost provides a detailed account of the various technologies, mission architectures, medical requirements and training needed to return humans to the Moon within the next decade. It focuses on the means by which a lunar outpost will be constructed and also addresses major topics such as the cost of the enterprise and the roles played by private companies and individual countries. The return of humans to the surface of the Moon will be critical to the exploration of the solar system. The various missions are not only in pursuit of scientific knowledge, but also looking to extend human civilization, economic expansion, and public engagement beyond Earth. As well as NASA, China’s Project 921, Japan’s Aerospace Exploration Agency, Russia, and the European Space Agency are all planning manned missions to the Moon and, eventually, to Mars. The Ares-I and Ares-V are the biggest rockets since the Saturn V and there is much state-of-the-art technology incorporated into the design of Orion, the spacecraft that will carry a crew of four astronauts to the Moon. Lunar Outpost also describes the human factors, communications, exploration activities, and life support constraints of the missions.

This book was released on 2008-06-29 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of the Vision for Space Exploration (VSE), NASA is planning for humans to revisit the Moon and someday go to Mars. An important consideration in this effort is protection against the exposure to space radiation. That radiation might result in severe long-term health consequences for astronauts on such missions if they are not adequately shielded. To help with these concerns, NASA asked the NRC to further the understanding of the risks of space radiation, to evaluate radiation shielding requirements, and recommend a strategic plan for developing appropriate mitigation capabilities. This book presents an assessment of current knowledge of the radiation environment; an examination of the effects of radiation on biological systems and mission equipment; an analysis of current plans for radiation protection; and a strategy for mitigating the risks to VSE astronauts.

This book was released on 2004-06-16 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Aerospace Initiative (NAI) was conceived as a joint effort between the Department of Defense (DOD) and the National Aeronautics and Space Administration (NASA) to sustain the aerospace leadership of the United States through the acceleration of selected aerospace technologies: hypersonic flight, access to space, and space technologies. The Air Force became concerned about the NAI's possible consequences on Air Force programs and budget if NAI program decisions differed from Air Force priorities. To examine this issue, it asked the NRC for an independent review of the NAI. This report presents the results of that assessment. It focuses on three questions asked by the Air Force: is NAI technically feasible in the time frame laid out; is it financially feasible over that period; and is it operationally relevant.

Available in PDF, EPUB and Kindle. Book excerpt: At the time of ?nalising this second volume of the ?Yearbook on Space Policy? which covers the period mid-2007 to mid-2008, Europe is as visible and strong in the area of space activities as never before. Its space probes are present on the Moon, around Mars, and on Saturn?s Moon Titan, and are chasing asteroids and comets; Ariane V is the most successful commercial launch vehicle; and more and more European space applications satellites are in operation. Finally, with the successful launch of the Columbus Orbital Facility (COF) – the most prominent highlight of this period which is also depicted on the cover of this Yearbook – and the ?rst Automated Transfer Vehicle (ATV), Europe has become a decisive player in human space?ight. This is accompanied by new policy initiatives on the ministerial level which have been bringing the European Space Agency and the European Union steadily closer. Europe?s outstanding development and positioning in the space ?eld is based not only on Europe?s successful engineering and scienti?c capabilities and capacities, but also on the forceful political determination of all European actors to maintain and even further their engagement in the use of outer space. And it is this political determination which provides the focus for this ?Yearbook on Space Policy?. The Yearbook describes and analyses the contexts and contents of space policy. Its primary ?eld of investigation is Europe, but it also covers the whole range of global space activities and their in?uence on European endeavours.

Book excerpt: The Republic of Korea's industrial policy has directed that nation's economy through nearly three decades of spectacular growth. But the authors of this paper maintain that this policy is showing signs of being outmoded. The time has come, the authors argue, for the Korean government to stop managing the economy's structural development and to redefine the responsibilities of business and government. Under this proposed compact, the allocation of resources would shift from the government to the private industrial and financial sectors. The transformation of the government bureaucracy from an ad hoc policy role to one of a transparent and predictable regulator is a key to the success of this undertaking. These new directions would present the government with enormous challenges. Greater competitive discipline and regulatory oversight would be required. While dealing with the complexities of the transition, the government would have to maintain macroeconomic stability and the momentum of savings and investment. For comparison, the study examines the industrial economies of France, Germany, Japan, and the United States, which underwent similar shifts.
