Comprehensive coverage of all aspects of NASA's James Webb Space Telescope (JWST), currently under construction and planned for launch sometime near 2018, is provided in this unique compilation of official NASA material. There is complete data on the JWST mission, science investigations, instruments and subsystems, unique mirror technology, the L2 orbit, special gyros, sunshield, infrared astronomy science to be obtained by the JWST, plus in-depth coverage of the funding controversy regarding the large cost overruns and schedule delays encountered by the project - with testimony from Congressional hearings, GAO reports, and the report of the Independent Comprehensive Review Panel (ICRP) along with NASA's response. Contents: PART 1 - JWST Basic Information: Spacecraft And Science Data, Project Status Updates; PART 2 - GAO Reports On JWST; PART 3 - Independent Comprehensive Review Panel (ICRP) Final Report; PART 4 - December 2011 Congressional Hearings on JWST. Dr. Roger Blandford noted in his testimony: JWST (formerly known as Next Generation Space Telescope) is a 6.5 meter diameter telescope. It is much larger than the Hubble Space Telescope (HST-2.4 meter diameter) and unlike HST, it will observe the universe from near the "second Lagrange Point", roughly four times as far away from the Earth as the moon but along the opposite direction to the sun. It will be protected from the sun by an elaborate sunshield. JWST is an engineering marvel and its 18 beryllium mirrors will be furled up within a rocket for launch and then deployed at its destination. This operation has to work perfectly as there will be no means of servicing it after launch. The principal scientific goals of JWST are bold and exciting and a culmination of nearly fifty years of extraordinary discovery about the universe and our place in it. They are: - to observe the very first stars, galaxies and black holes which formed at a time when the universe was about four percent of its present age - to discover how stars and planets actually form today within our Galaxy - to study planets orbiting nearby cool stars and assess their habitability However, JWST will also operate as an astronomical observatory and many, and perhaps most, areas of astronomy will be transformed by JWST in much the same way as they have been revolutionized by HST. JWST is specialized to observe in the infrared region of the spectrum. This is relevant because, although much light emitted by the most distant galaxies is in the optical and ultraviolet spectral bands, the wavelengths of this light are stretched roughly tenfold through the expansion of the universe into the infrared band, as we push out to greater distance and earlier times. There is a second reason why it is preferred to observe in the infrared and this is that the star-forming regions that will be intensively studied by JWST are filled with tiny grains of dust. These dust grains absorb and scatter optical and ultraviolet light but leave infrared radiation alone, enabling us to see deep inside them at these wavelengths. In addition, the light that is absorbed by dust will be re-emitted at infrared wavelengths and we can also observe the dust itself as a tell-tale tracer of star formation. As well as being the natural successor of HST, JWST is the infrared successor of the much smaller (0.85 meter diameter) Spitzer Space Telescope, with over 50 times the light-gathering ability and 40 times the resolution as well as the Herschel telescope, led by the European Space Agency, which only observes at longer infrared wavelengths than JWST. Given this huge increase in performance over and complementarity to previous telescopes, JWST promises to be a scientific "game changer".

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.

This publication, "Making the Invisible Visible: A History of the Spitzer Infrared Telescope Facility (1971-2003)," makes visible the invisible forces that influenced the design of Space Infrared Telescope Facility (SIRTF's) innovative technology. The lessons learned by the project team over the course of building SIRTF, now better known as the Spitzer Space Telescope, are about managing innovation over time and in the face of uncertainty. These are universal lessons, applicable to any project whose stakeholders control the necessary resources. SIRTF's stakeholders focused on a variety of issues: technical, scientific, political, and economic, as well as organizational needs and goals. What made SIRTF's evolution particularly difficult was that the stakeholders changed over time-in their composition, goals, and influence.

The steering committee was specifically asked to (1) provide an overview of the current state of astronomy and astrophysics science, and technology research in support of that science, with connections to other scientific areas where appropriate; (2) identify the most compelling science challenges and frontiers in astronomy and astrophysics, which shall motivate the committee’s strategy for the future; (3) develop a comprehensive research strategy to advance the frontiers of astronomy and astrophysics for the period 2022-2032 that will include identifying, recommending, and ranking the highest-priority research activities; (4) utilize and recommend decision rules, where appropriate, that can accommodate significant but reasonable deviations in the projected budget or changes in urgency precipitated by new discoveries or unanticipated competitive activities; (5) assess the state of the profession, including workforce and demographic issues in the field, identify areas of concern and importance to the community, and where possible, provide specific, actionable, and practical recommendations to the agencies and community to address these areas. This report proposes a broad, integrated plan for space- and ground-based astronomy and astrophysics for the decade 2023-2032. It also lays the foundations for further advances in the following decade.

This book documents highlights of NASA's interactions with outside scientific advisors over the agency's full lifetime and draws lessons from that history for research managers, decision makers, and scientists.The book is divided into three parts--the first two being focused on history and the third on synthesis and analysis. Part 1 briefly examines early forerunner activities at NACA and in the decade leading up to NASA's formation, and it then considers NASA's use of outside advice during its first three decades. Part 2 picks up the story in 1988 and follows it up to 2016. Part 3 examines a sampling of case studies, discusses recurring characteristics of notably successful advisory activities, and provides a glimpse at what past experience might imply for the future of scientific advice at NASA. The last two chapters provide big-picture summaries of themes that have emerged from earlier discussions.

"To commemorate the 50th anniversary of the first successful planetary mission, Mariner 2 sent to Venus in 1962, the NASA History Program Office, the Division of Space History at the National Air and Space Museum, NASA's Science Mission Directorate, and the Jet Propulsion Laboratory organized a symposium. "Solar System Exploration @ 50" was held in Washington, D.C., on 25-26 October 2012. The purpose of this symposium was to consider, over the more than 50-year history of the Space Age, what we have learned about the other bodies of the solar system and the processes by which we have learned it. Symposium organizers asked authors to address broad topics relating to the history of solar system exploration such as various flight projects, the development of space science disciplines, the relationship between robotic exploration and human spaceflight, the development of instruments and methodologies for scientific exploration, as well as the development of theories about planetary science, solar system origins and implications for other worlds. The papers in this volume provide a richly textured picture of important developments - and some colorful characters - in a half century of solar system exploration. A comprehensive history of the first 50 years of solar system exploration would fill many volumes. What readers will find in this volume is a collection of interesting stories about money, politics, human resources, commitment, competition and cooperation, and the "faster, better, cheaper" era of solar system exploration"--

This book describes our gradual awareness of a vast, previously concealed Universe. It is a story of expanding horizons and the discovery of invisible worlds. This voyage of discovery is presented within universal themes, such as invisibility, motion, content, form, impermanence, violence and emptiness, beginnings and ends. These are topics that concern us all, helping us take the Universe personally, so each chapter begins with the human aspect of some of these themes. The book is additionally broadened by including the perceptions of artists, poets and writers, as well as with line drawings that forcefully compact a scientific insight.
