The technological marvel that facilitated the Apollo missions to the Moon was the on-board computer. In the 1960s most computers filled an entire room, but the spacecraft\'s computer was required to be compact and low power. Although people today find it difficult to accept that it was possible to control a spacecraft using such a \'primitive\' computer, it nevertheless had capabilities that are advanced even by today\'s standards.This is the first book to fully describe the Apollo guidance computer\'s architecture, instruction format and programs used by the astronauts. As a comprehensive account, it will span the disciplines of computer science, electrical and aerospace engineering. However, it will also be accessible to the \'space enthusiast\'. In short, the intention is for this to be the definitive account of the Apollo guidance computer.Frank O\'Brien\'s interest in the Apollo program began as a serious amateur historian. About 12 years ago, he began performing research and writing essays for the Apollo Lunar Surface Journal, and the Apollo Flight Journal. Much of this work centered on his primary interests, the Apollo Guidance Computer (AGC) and the Lunar Module. These Journals are generally considered the canonical online reference on the flights to the Moon. He was then asked to assist the curatorial staff in the creation of the Cradle of Aviation Museum, on Long Island, New York, where he helped prepare the Lunar Module simulator, a LM procedure trainer and an Apollo space suit for display. He regularly lectures on the Apollo computer and related topics to diverse groups, from NASA\'s computer engineering conferences, the IEEE/ACM, computer festivals and university student groups. Today\'s astronauts require many different abilities. They must not only be expert in performing flight simulations but must also be proficient in such dissimilar subjects as photography, thermodynamics, electrical repairs, flight procedures, oceanography, public affairs, and geology. In Prepare for Launch, the author introduces the technologies and myriad activities that constitute or affect astronaut training, such as the part-task trainers, emergency procedures, the fixed-based and motion-based simulators, virtual environment training, and the demands of training in the Weightless Environment Training Facility. With plans to return to the Moon and future missions to Mars, the current selection criteria and training are very different from those used for short duration mission Space Shuttle crews. Dr. Erik Seedhouse in this book focuses on how astronaut candidates are taught to cope with different needs and environments (for example, hibernation, artificial gravity, and bioethics issues) and also includes brief discussions of the astronaut application and selection process. The book focuses on the design, testing and manufacture of the F-1 engine, but also covers its incorporation into the first stage of the Saturn V and in-flight record. It concludes with an examination of what might have been, if the F-1 had not been discarded, together with the Saturn V, at the conclusion of the Apollo program. The account draws on original documents and interviews with engineers and managers, and is illustrated by many never-before-published photographs, both colour and monochrome. The intention is for this to be the definitive account of the development of this most powerful of rocket engines. As NASA is developing an evolved version of the hydrogen-burning J-2 engine for use in the forthcoming Ares launch vehicles, the author includes development of the J-2 engine within the context of the Saturn V development, thus bringing rocket engine development up to the present and thus provide this book with a long shelf life. On 25 May 1961, John F Kennedy announced the goal of landing an American man on the Moon by the end of the decade. This challenge forced NASA to review the planned lunar landing of a three-man spaceship named Apollo in the mid-1970s. In 1962, it was decided that a specialized vehicle would accompany the main spacecraft, to make the lunar landing while the mothership remained in lunar orbit. To send these vehicles to the Moon would require the development of an enormous rocket. Development was protracted, but in December 1968 Apollo 8 was launched on a pioneering mission to perform an initial reconnaissance in lunar orbit. When Apollo 17 lifted off from the Moon in December 1972, the program was concluded. Now, at long last, there is a real prospect of a resumption of human exploration of the Moon.This book provides an overview of the origins of the Apollo program and descriptions of the ground facilities, launch vehicles and spacecraft that will serve as an invaluable single-volume \'sourcebook\' for space enthusiasts, space historians, journalists, and programme-makers on radio/TV. It supplements other books that have focused on the politics and management of the Apollo program, the astronauts, and their training and exploits. Creating spacesuits is an ongoing challenge that has spanned over four decades. This book details the evolution of U. S. spacesuits from their roots in high altitude aviation and vacuum tube development to the present day, with a glimpse into the future. David Harland opens with a review of the robotic probes, namely the Rangers which returned television before crashing into the Moon, the Surveyors which \'soft landed\' in order to investigate the nature of the surface, and the Lunar Orbiters which mapped prospective Apollo landing sites. He then outlines the historic landing by Apollo 11 in terms of what was discovered. He concludes with a review of the robotic spacecraft that made remote-sensing observations of the Moon. The book develops the scientific theme of lunar geology, and therefore will be of use as background reading for undergraduate students of planetary sciences. Highlighted as a Commemorative Edition on the cover, this second edition has a new Foreword by one of the original astronauts and a short extra section at the end previewing the prospect of a renewal of human exploration of the Moon. It includes new extra high quality graphics which are only now available and 32 pages of color illustrations. This accessible book offers an imaginative journey through the Universe in search of water, founded on the latest science. The author begins by re-introducing the molecule H2O, its physical and chemical characteristics, its cosmic formation and abundance. The book goes on to describe methods by which the presence of water is detected, within the solar system and beyond. The book explores the presence and absence of water in the bodies of the Solar System: in the giant planets, with their rings and satellites, in comets, asteroids and in the terrestrial planets. The author explains how small differences in temperature cause water to exist in different states on different planets - vapour on Venus, liquid on Earth and solid ice on Mars - leading to divergence in the evolutionary paths of the three planets. The book concludes with a look at the important role played by water in studies of habitable exoplanets. The book focuses on the design, testing and manufacture of the F-1 engine, but also covers its incorporation into the first stage of the Saturn V and in-flight record.

In Energiya-Buran: the Soviet Space Shuttle, the authors describe the long development path of the Soviet space shuttle system, consisting of the Energiya rocket and the Buran orbiter. The program eventually saw just one unmanned flight in November 1988 before the end of the Cold War and the collapse of the Soviet Union sealed its fate.After a Foreword provided by lead Buran test pilot Igor Volk, the authors look at the experience gradually accumulated in high-speed aeronautics with the development of various Soviet rocket planes and intercontinental cruise missiles between the 1930s to 1950s and the study of several small spaceplanes in the 1960s. Next the authors explain how the perceived military threat of the US Space Shuttle led to the decision in February 1976 to build a Soviet equivalent, and explore the evolution of the design until it was frozen in 1979. Following this is a detailed technical description of both Energiya and Buran and a look at nominal flight scenarios and emergency situations, highlighting similarities and differences with the US Space Shuttle.The authors then expand on the managerial aspects of the Energiya-Buran program, sum up the main design bureaus and production facilities involved in the project and describe the infrastructure needed to transport the hardware and prepare it for launch at the Baikonur cosmodrome. They go on to detail the selection and training of teams of civilian and military test pilots for Buran, crew assignments for the first manned missions and preparatory flights aboard Soyuz spacecraft.Next the focus turns to the extensive test program that preceded the first flight of Buran, notably the often trouble-plagued test firings of rocket engines, the first flight of Energiya with the enigmatic Polyus payload, test flights of subscale models and atmospheric approach and landing tests. After an analysis of Western speculation on the Soviet space shuttle effort in the pre-glasnost era, a detailed account is given of final preparations for the maiden flight of Buran and the mission itself.In the final chapters the authors look at the gradual demise of the project in the early 1990s, the fate of the Soviet orbiters and their cosmodrome infrastructure, cancelled missions, and the many planned derivatives of the Energiya rocket. Attention is also paid to technological spin-offs such as the Zenit and Sea Launch projects and the RD-180 and RD-191 rocket engines. Finally, an overview is given of alternative spaceplane proposals during and after the Buran era, including the MAKS air-launched spaceplane, the Kliper spacecraft and various single-stage-to-orbit systems.The book closes off with key specifications of the Energiya-Buran system, short biographies of the Buran pilots, an extensive list of Russian acronyms, a short bibliographical essay and a detailed index. Based largely on Russian sources, it is richly illustrated with some 250 pictures and diagrams.Although Energiya-Buran was primarily a program of unfulfilled promises and shattered dreams, it represented a major technological breakthrough for the Soviet Union and its story deserves to be told.
