دانلود کتاب Stepping-Stones to the Future of Space Exploration: A Workshop Report

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 relationship of the various stakeholders in advancing human and robotic exploration and development of space. The first workshop, which is the topic of this report, focused on policy issues about the development and demonstration of space technologies. Four policy topics?selected by the project steering committee as the foci of this first workshop?are discussed in the report: the rationale for human and robotic space exploration; technology as a driver for capability transformation; risk mitigation and perception; and international cooperation and competition.
