Laying the Foundation for Space Solar Power
In March 2000, NASA's Office of Space Flight asked the Aeronautics and Space Engineering Board of the National Research Council to perform an independent assessment of the space solar power program's technology investment strategy to determine its technical soundness and its contribution to the roadmap that NASA has developed for this program. The program's investment strategy was to be evaluated in the context of its likely effectiveness in meeting the program's technical and economic objectives.

Space-Based Solar Power
With growing international awareness of energy security challenges, the promise of space-based solar power for clean and unlimited energy for all humankind is certainly appealing. While significant progress continues in the enabling technologies of such systems, is there compelling evidence that space-based solar power systems will provide the best energy solution? How does the Army's current approach to incorporating a diverse portfolio of renewable energy sources in distributed locations compare to the potential of enterprise ventures that beam energy from solar collectors in space? For over 4 decades, many credible organizations in government and industry have explored the concept of spac...
Assessment of Options for Extending the Life of the Hubble Space Telescope
The Hubble Space Telescope (HST) has operated continuously since 1990. During that time, four space shuttle-based service missions were launched, three of which added major observational capabilities. A fifth â€" SM-4 â€" was intended to replace key telescope systems and install two new instruments. The loss of the space shuttle Columbia, however, resulted in a decision by NASA not to pursue the SM-4 mission leading to a likely end of Hubble's useful life in 2007-2008. This situation resulted in an unprecedented outcry from scientists and the public. As a result, NASA began to explore and develop a robotic servicing mission; and Congress directed NASA to request a study from the National Research Council (NRC) of the robotic and shuttle servicing options for extending the life of Hubble. This report presents an assessment of those two options. It provides an examination of the contributions made by Hubble and those likely as the result of a servicing mission, and a comparative analysis of the potential risk of the two options for servicing Hubble. The study concludes that the Shuttle option would be the most effective one for prolonging Hubble's productive life.
Solar and Space Physics and Its Role in Space Exploration
In February 2004, the President announced a new goal for NASA; to use humans and robots together to explore the Moon, Mars, and beyond. In response to this initiative, NASA has adopted new exploration goals that depend, in part, on solar physics research. These actions raised questions about how the research agenda recommended by the NRC in its 2002 report, The Sun to the Earth and Beyond, which did not reflect the new exploration goals, would be affected. As a result, NASA requested the NRC to review the role solar and space physics should play in support of the new goals. This report presents the results of that review. It considers solar and space physics both as aspects of scientific exploration and in support of enabling future exploration of the solar system. The report provides a series of recommendations about NASA's Sun-Earth Connections program to enable it to meet both of those goals.
TWENTY-FIRST CENTURY'S FUEL SUFFICIENCY ROADMAP
We badly need new sources of clean energy to generate electricity, heat and power our industries, homes and workplaces. Up to now, we have relied on and used only fossil fuels to power our industrial and domestic activities. The byproducts of fossil fuels include: irreversible pollution and contamination of our Earth, climate change, global warming, and increase in pathogenic and medication-resistant diseases. Exhaustible fossil fuels are expensive to produce and distribute, and not everybody can afford them. Why not switch to natural, non-polluting, inexpensive, inexhaustible fuels such as solar, wind, water, etc., fuels? This is the timely message contained in TWENTY-FIRST CENTURY'S FUEL SUFFICIENCY ROADMAP. You can make this message realisable. Go on reading! Thanks.
Government/Industry/Academic Relationships for Technology Development
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 developmentâ€"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 second workshop, which is the summarized in this report, focused on the interrelationship between government, industry, and academia in the development of technology. Examples from Defense Advanced Research Projects Agency, the Department of Defense, and the National Science Foundation were covered in order to discuss best practices of such cooperative efforts as possible lessons for NASA's space exploration activities.
