This book was released on 2017-05-04 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this paper is to present an analysis and a historical review of the Apollo Lunar Module landing dynamics from the standpoint of touchdown dynamic stability, landing system energy absorption performance, and evaluation of the first-order terms of lunar soil mechanical properties at the Apollo 11 landing site. The first-order terms of lunar surface mechanical properties consisted primarily of the surface bearing strength and sliding friction coefficient. The landing dynamic sequence started at first footpad contact. The flight dynamics data used to assess the Apollo 11 landing system performance and the lunar soil mechanical properties included the body axis pitch, roll, and yaw rate time histories as measured by the on-board guidance computer during the Apollo 11 Lunar Module touchdown maneuver, and the landing gear stroke data derived from post-landing photographs. The conclusions drawn from these studies were that the landing gear system performance was more than adequate from a stability and energy absorption standpoint for all Apollo lunar landings, and the lunar soil parameters were well within the limits of the design assumptions for all Apollo landing sites.

Book Synopsis Apollo Mission Control by : Manfred "Dutch" von Ehrenfried
Download or read book Apollo Mission Control written by Manfred "Dutch" von Ehrenfried and published by Springer. This book was released on 2018-06-21 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the history of this now iconic room which represents America’s space program during the Gemini, Apollo, Skylab, Apollo-Soyuz and early Space Shuttle eras. It is now a National Historic Landmark and is being restored to a level which represents the day the flight control teams walked out after the last lunar landing missions. The book is dedicated to the estimated 3,000 men and women who supported the flights and tells the story from their perspective. It describes the rooms of people supporting this control center; those rooms of engineers, analysts and scientists most people never knew about. Some called it a “shrine” and some called it a “cathedral.” Now it will be restored to its former glory and soon thousands will be able to view the place where America flew to the moon.

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.

Download or read book Apollo and America's Moon Landing Program - Project Apollo written by World Spaceflight News and published by . This book was released on 2018-01-05 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: This official NASA history document presents a narrative account of the Apollo lunar landing program from its origin through its assessment. The preface states: "The program to land an American on the Moon and return safely to Earth in the 1960s has been called by some observers a defining event of the twentieth century. Pulitzer Prize-winning historian Arthur M. Schlesinger, Jr., even suggested that when Americans two centuries hence study the twentieth century, they will view the Apollo lunar landing as the critical event of the century. While that conclusion might be premature, there can be little doubt but that the flight of Apollo 11 in particular and the overall Apollo program in general was a high point in humanity's quest to explore the universe beyond Earth." From the introduction: "On 25 May 1961 President John F. Kennedy announced to the nation a goal of sending an American safely to the Moon before the end of the decade. This decision involved much study and review prior to making it public, and tremendous expenditure and effort to make it a reality by 1969. Only the building of the Panama Canal rivaled the Apollo program's size as the largest non- military technological endeavor ever undertaken by the United States; only the Manhattan Project was comparable in a wartime setting. The human spaceflight imperative was a direct outgrowth of it; Projects Mercury (at least in its latter stages), Gemini, and Apollo were each designed to execute it. It was finally successfully accomplished on 20 July 1969, when Apollo 11's astronaut Neil Armstrong left the Lunar Module and set foot on the surface of the Moon." Contents include: The Kennedy Perspective on Space * The Soviet Challenge Renewed * Reevaluating NASA's Priorities * The NASA Position * Decision * An Assessment of the Decision * Gearing Up for Project Apollo * The Program Management Concept * How Do We Go to the Moon? * Prelude to Apollo: Mercury * Bridging the Technological Gap: From Gemini to Apollo * Satellite Support of Apollo * Building Saturn * The Apollo Spacecraft * The Lunar Module * Trips to the Moon * A Meaning for Apollo

Book Synopsis The Apollo Missions by : David Baker
Download or read book The Apollo Missions written by David Baker and published by Arcturus Publishing. This book was released on 2018-12-12 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long has the moon captured the imagination of world; from science fiction to astrology; howling wolves to lunar calendars. To President John F. Kennedy, however, the moon was a destination. To put a man on the moon would be to challenge Russia's recent achievements in space exploration and assert the US's technological prowess on the world stage. As we know, the mission was a success, and yet while everyone is familiar with Neil Armstrong's iconic line and his bold tread on the moon's dusty surface, few are privy to the events leading up to this moment. Former NASA engineer, David Baker, gives a behind-the-scenes account of the space race, including the political impetus behind the mission, the Apollo 8's lunar orbit on Christmas Eve, as well as some of the tale's tragedies. Bursting with fascinating stories, striking photographs of the team and exclusive material provided by NASA personnel, this book perfectly captures the risk, complexity and gravitas of this immense journey.

Book Synopsis Digital Apollo by : David A. Mindell
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.
