Available in PDF, EPUB and Kindle. Book excerpt: Progress in Astronautics and Rocketry, Volume 10: Technology of Lunar Exploration is an overview of the technical base of the lunar exploration problem. This volume is organized into six sections encompassing 35 that follow the various stages of accomplishment of a lunar mission, involving landing on or orbiting the moon and returning to the earth. The first section is devoted to the problem of trying to define the lunar environment, emphasizing the theories of the lunar environment as it relates to the internal structure of the moon. This section also describes some activities to achieve a reasonable theory concerning what might be encountered in some of the previous lunar flight programs. The second section explores the problems associated with the limitations imposed upon lunar missions by the launch vehicles and launching facilities. The third section looks at the spacecraft systems and techniques required for lunar missions, particularly the technology and specific subsystems in relation to the requirements imposed by specific lunar mission objectives. The fourth section deals with the actual landing on the moon and the subsequent surface operations, while the fifth section covers the lunar launch, return, flight re-entry, and subsequent landing on earth. The sixth section reports the status of the projects that represent the United States lunar exploration program, which integrates the technologies developed in the preceding sections into certain discrete projects.

Download or read book One Giant Leap written by Charles Fishman and published by Simon & Schuster. This book was released on 2020-09-22 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: The New York Times bestselling, “meticulously researched and absorbingly written” (The Washington Post) story of the trailblazers and the ordinary Americans on the front lines of the epic Apollo 11 moon mission. President John F. Kennedy astonished the world on May 25, 1961, when he announced to Congress that the United States should land a man on the Moon by 1970. No group was more surprised than the scientists and engineers at NASA, who suddenly had less than a decade to invent space travel. When Kennedy announced that goal, no one knew how to navigate to the Moon. No one knew how to build a rocket big enough to reach the Moon, or how to build a computer small enough (and powerful enough) to fly a spaceship there. No one knew what the surface of the Moon was like, or what astronauts could eat as they flew there. On the day of Kennedy’s historic speech, America had a total of fifteen minutes of spaceflight experience—with just five of those minutes outside the atmosphere. Russian dogs had more time in space than US astronauts. Over the next decade, more than 400,000 scientists, engineers, and factory workers would send twenty-four astronauts to the Moon. Each hour of space flight would require one million hours of work back on Earth to get America to the Moon on July 20, 1969. “A veteran space reporter with a vibrant touch—nearly every sentence has a fact, an insight, a colorful quote or part of a piquant anecdote” (The Wall Street Journal) and in One Giant Leap, Fishman has written the sweeping, definitive behind-the-scenes account of the furious race to complete one of mankind’s greatest achievements. It’s a story filled with surprises—from the item the astronauts almost forgot to take with them (the American flag), to the extraordinary impact Apollo would have back on Earth, and on the way we live today. From the research labs of MIT, where the eccentric and legendary pioneer Charles Draper created the tools to fly the Apollo spaceships, to the factories where dozens of women sewed spacesuits, parachutes, and even computer hardware by hand, Fishman captures the exceptional feats of these ordinary Americans. “It’s been 50 years since Neil Armstrong took that one small step. Fishman explains in dazzling form just how unbelievable it actually was” (Newsweek).
Download or read book Digital Apollo written by David A. Mindell and published by MIT Press. This book was released on 2011-09-30 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: The incredible story of how human pilots and automated systems worked together to achieve the ultimate achievement in flight—the lunar landings of NASA’s Apollo program As Apollo 11’s Lunar Module descended toward the moon under automatic control, a program alarm in the guidance computer’s software nearly caused a mission abort. Neil Armstrong responded by switching off the automatic mode and taking direct control. He stopped monitoring the computer and began flying the spacecraft, relying on skill to land it and earning praise for a triumph of human over machine. In Digital Apollo, engineer-historian David Mindell takes this famous moment as a starting point for an exploration of the relationship between humans and computers in the Apollo program. In each of the six Apollo landings, the astronaut in command seized control from the computer and landed with his hand on the stick. Mindell recounts the story of astronauts’ desire to control their spacecraft in parallel with the history of the Apollo Guidance Computer. From the early days of aviation through the birth of spaceflight, test pilots and astronauts sought to be more than “spam in a can” despite the automatic controls, digital computers, and software developed by engineers. Digital Apollo examines the design and execution of each of the six Apollo moon landings, drawing on transcripts and data telemetry from the flights, astronaut interviews, and NASA’s extensive archives. Mindell’s exploration of how human pilots and automated systems worked together to achieve the ultimate in flight—a lunar landing—traces and reframes the debate over the future of humans and automation in space. The results have implications for any venture in which human roles seem threatened by automated systems, whether it is the work at our desktops or the future of exploration.
Download or read book A Constrained Space Exploration Technology Program written by National Research Council and published by National Academies Press. This book was released on 2009-01-29 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: In January 2004, President George W. Bush announced the Vision for Space Exploration (VSE), which instructed NASA to "Extend human presence across the solar system, starting with a human return to the Moon by the year 2020, in preparation for human exploration of Mars and other destinations," among other objectives. As acknowledged in the VSE, significant technology development will be necessary to accomplish the goals it articulates. NASA's Exploration Technology Development Program (ETDP) is designed to support, develop, and ultimately provide the necessary technologies to meet the goals of the VSE. This book, a review of the ETDP, is broadly supportive of the intent and goals of the VSE, and finds the ETDP is making progress towards the stated goals of technology development. However, the ETDP is operating within significant constraints which limit its ability to successfully accomplish those goals-the still dynamic nature of the Constellation Program requirements, the constraints imposed by a limited budget, the aggressive time scale of early technology deliverables, and the desire to fully employ the NASA workforce.

Download or read book Extended Duration Lunar Lander written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-17 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selenium Technologies has been conducting preliminary design work on a manned lunar lander for use in NASA's First Lunar Outpost (FLO) program. The resulting lander is designed to carry a crew of four astronauts to a prepositioned habitat on the lunar surface, remain on the lunar surface for up to 45 days while the crew is living in the habitat, then return the crew to earth via direct reentry and land recovery. Should the need arise, the crew can manually guide the lander to a safe lunar landing site, and live in the lander for up to ten days on the surface. Also, an abort to earth is available during any segment of the mission. The main propulsion system consists of a cluster of four modified Pratt and Whitney RL10 rocket engines that use liquid methane (LCH4) and liquid oxygen (LOX). Four engines are used to provide redundancy and a satisfactory engine out capability. Differences between the new propulsion system and the original system include slightly smaller engine size and lower thrust per engine, although specific impulse remains the same despite the smaller size. Concerns over nozzle ground clearance and engine reliability, as well as more information from Pratt and Whitney, brought about this change. The power system consists of a combination of regenerative fuel cells and solar arrays. While the lander is in flight to or from the moon, or during the lunar night, fuel cells provide all electrical power. During the lunar day, solar arrays are deployed to provide electrical power for the lander as well as electrolyzers, which separate some water back into hydrogen and oxygen for later use by the fuel cells. Total storage requirements for oxygen, hydrogen, and water are 61 kg, 551 kg, and 360 kg, respectively. The lander is a stage-and-a-half design with descent propellant, cargo, and landing gear contained in the descent stage, and the main propulsion system, ascent propellant, and crew module contained in the ascent stage. The primary structure for both sta...
Download or read book Review of NASA s Exploration Technology Development Program written by National Research Council and published by National Academies Press. This book was released on 2009-01-12 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: To meet the objectives of the Vision for Space Exploration (VSE), NASA must develop a wide array of enabling technologies. For this purpose, NASA established the Exploration Technology Development Program (ETDP). Currently, ETDP has 22 projects underway. In the report accompanying the House-passed version of the FY2007 appropriations bill, the agency was directed to request from the NRC an independent assessment of the ETDP. This interim report provides an assessment of each of the 22 projects including a quality rating, an analysis of how effectively the research is being carried out, and the degree to which the research is aligned with the VSE. To the extent possible, the identification and discussion of various cross-cutting issues are also presented. Those issues will be explored and discussed in more detail in the final report.

Available in PDF, EPUB and Kindle. Book excerpt: ÔThe recent renaissance in the use of prizes to spur innovation and extraordinary novel performance warrants close attention. Luciano Kay does so through a series of compelling case studies which shows the potential of prizes, the range of factors that influence their performance and the importance of understanding their non-pecuniary dimensions, even when there is a substantial purse. This is an important contribution to the innovation literature.Õ Ð David J. Teece, University of California, Berkeley, US ÔIn the last decade innovation prizes have caught the imagination of policy makers and rich donors alike; those who actually care about the process and outcome of prizes and not only the hype, would do well to read LucianoÕs new book.Õ Ð Dan (Danny) Breznitz, Georgia Institute of Technology, US Inducement prizes Ð in which cash rewards are offered to motivate the attainment of specific targets Ð have long been used to stimulate scientific discovery and technology research and development. This volume presents an empirical investigation of the effect of these prizes on innovation. In this in-depth study, Luciano Kay focuses on three recent cases of prize competitions in the aerospace industry: the Google Lunar X Prize, the Ansari X Prize and the Northrop Grumman Lunar Lander Challenge. Using a combination of real-time and historical analysis based on personal interviews, workplace visits and questionnaire and document data analysis, the author examines the particular dynamics of the prize phenomenon and offers a comprehensive discussion of the potential of prizes to induce innovation. This fascinating volume also sets out a systematic method to studying prize incentives, offering a concrete innovation model and case study design approach that will prove highly useful to further research efforts in the field. Scholars, policymakers and corporate officials interested in incentives for innovation and the practical implementation of prize competitions will find this an invaluable resource. Potential prize sponsors and entrepreneurs, professionals and other individuals or organizations interested in participating in such competitions will also find much of interest in this groundbreaking book.
Download or read book Mars via the Moon written by Erik Seedhouse and published by Springer. This book was released on 2015-11-28 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: MOMENTUM IS BUILDING for a return to the Moon. NASA’s international partners on the International Space Station are in favor of returning to the lunar surface, as are India and China. The horizon goal may be Mars, but the political, funding and the technological and medical infeasibility of such an objective means the next logical step is a return to the Moon. While much has been learned about the Moon over the years, we don’t understand its resource wealth potential and the technologies to exploit those resources have yet to be developed, but there are a number of companies that are developing these capabilities. And, with the discovery of water in the lunar polar regions, plans are in the works to exploit these resources for fuel for transportation operations in cis-lunar space and in low Earth orbit (LEO). The time has come for commercial enterprise to lead the way back to the lunar surface. Embarking on such a venture requires little in the way of new technologies. We don’t need to develop super-fast propulsion systems like those required to get us to Mars safely, nor do we need hundreds of billions of dollars that the experts reckon it will cost to transport humans to the Red Planet. What we do need is a place to test the technologies and deep space experience that will enable us to build a pathway that will lead us to Mars. That place is the Moon and this book explains why.
Download or read book Early Exploration of the Moon written by Tom Lund and published by Springer. This book was released on 2018-12-26 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Luna 2, launched by the USSR in 1959, was the first spacecraft from Earth to land on the moon. That first voyage was followed by increasingly capable lunar exploration spacecraft from Russia and the United States. A total of 36 successful lunar exploration missions were conducted from 1959 to the last Apollo manned exploration in 1972 and the final travels of the Lunokhod lunar rover in 1973. Of all the missions, that of Apollo 17 was the pinnacle of manned space exploration. Apollo 17 astronauts traveled 21 miles on the lunar surface in a dune buggy-type vehicle, stopping frequently to explore and gather samples. The spacecraft that enabled lunar exploration were ingenious, and reflected the best efforts of talented people working with the technology of the day. This book showcases the engineering involved in those incredible machines. The spacecraft covered, and their missions, are listed below. From the United States: • Ranger – Photography en route to lunar impact • Lunar Orbiter – Photography of front and back side of moon • Surveyor – Soft landing, photography, and soil analysis • Apollo – Manned exploration. Lunar Rover expanded range From the USSR: • Luna 2 – Photography en route to lunar impact • Luna 3 – Photography of back side of moon on flyby • Luna 9 and 13 – Soft landing, photography, and soil analysis • Luna 10, 11, 12, 14 – Photography from lunar orbit • Luna 16, 20, 24 – Soft landing, return of soil sample to Earth • Lunokhod-1, -2 – Lunar roving vehicle driven from Earth • L1 – Planned manned lunar flyby but only flew unmanned • L3 – Planned manned lunar landing but never flew to moon To tell the story of these spacecraft, Tom Lund draws on over 40 years’ work on aircraft and spacecraft systems. He was technical lead for the landing radars for the Surveyor and Apollo spacecraft, and his practical experience is augmented by master’s degrees in electrical engineering, physics, and business administration.
Download or read book Moon Lander written by Thomas J. Kelly and published by Smithsonian Institution. This book was released on 2012-01-11 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chief engineer Thomas J. Kelly gives a firsthand account of designing, building, testing, and flying the Apollo lunar module. It was, he writes, “an aerospace engineer’s dream job of the century.” Kelly’s account begins with the imaginative process of sketching solutions to a host of technical challenges with an emphasis on safety, reliability, and maintainability. He catalogs numerous test failures, including propulsion-system leaks, ascent-engine instability, stress corrosion of the aluminum alloy parts, and battery problems, as well as their fixes under the ever-present constraints of budget and schedule. He also recaptures the exhilaration of hearing Apollo 11’s Neil Armstrong report that “The Eagle has landed,” and the pride of having inadvertently provided a vital “lifeboat” for the crew of the disabled Apollo 13.

Available in PDF, EPUB and Kindle. Book excerpt: AFTER THE LUNAR LANDING Our concern in this volume is the impact upon science, technology and international cooperation of man's emer gence from the "cradle," the biosphere of Earth, to visit the surface of another planet. The editors invited experts in the physical and social sciences who had been think ing, talking and writing about space programs for a long time. Some had been critical of manned space flight, its motives and its costs. Some have been or are currently involved in Project Apollo. Some had not committed themselves to value judgments but were fascinated by probable results. In general, the authors regard the moon landing as a climactic event in man's evolution. Sir Bernard Lovell is likely to have a cataclysmic effect on society suggests it and that an international effort should be mounted to send men to Mars in the 1980s. The question of how Project Apollo relates to a scheme of priorities which takes into account such needs as housing, health, pollution and the problems of urbaniza tion enters the discussion from several points of view. Eugene Rabinowitch suggests that Apollo may stimulate the development of a system of establishing national priorities in the application of the nation's resources. Freeman Dyson, on the other hand, does not believe that ix PREFACE x any "hierarchy of committees" can devise an accepted order of priorities.
