Now a major film starring Ryan Gosling, Claire Foy and Kyle Chandler, directed by Oscar-winner Damien Chazelle, First Man by James Hansen offers the only authorized glimpse into the life of America's most famous astronaut, Neil Armstrong - the man whose "one small step" changed history. In First Man, Hansen explores the life of Neil Armstrong. Based on over 50 hours of interviews with the intensely private Armstrong, who also gave Hansen exclusive access to private documents and family sources, this "magnificent panorama of the second half of the American twentieth century" (Publishers Weekly, Starred Review) is an unparalleled biography of an American icon. When Apollo 11 touched down on the moon's surface in 1969, the first man on the moon became a legend. Hansen vividly recreates Armstrong's career in flying, from his seventy-eight combat missions as a naval aviator flying over North Korea to his formative transatmospheric flights in the rocket-powered X-15 to his piloting Gemini VIII to the first-ever docking in space. For a pilot who cared more about flying to the Moon than he did about walking on it, Hansen asserts, Armstrong's storied vocation exacted a dear personal toll, paid in kind by his wife and children. In the years since the Moon landing, rumors swirled around Armstrong concerning his dreams of space travel, his religious beliefs, and his private life. This book reveals the man behind the myth. In a penetrating exploration of American hero worship, Hansen addresses the complex legacy of the First Man, as an astronaut and as an individual. In First Man, the personal, technological, epic, and iconic blend to form the portrait of a great but reluctant hero who will forever be known as history's most famous space traveler.

Viewing and Imaging the Solar System - A Guide for Amateur Astronomers (Paperback, 2015 ed.): Jane Clark Viewing and Imaging the Solar System - A Guide for Amateur Astronomers (Paperback, 2015 ed.)
Jane Clark
R1,784 Discovery Miles 17 840 Ships in 18 - 22 working days

Viewing and Imaging the Solar System: A Guide for Amateur Astronomers is for those who want to develop their ability to observe and image Solar System objects, including the planets and moons, the Sun, and comets and asteroids. They might be beginners, or they may have already owned and used an astronomical telescope for a year or more. Newcomers are almost always wowed by sights such as the rings of Saturn and the moons of Jupiter, but have little idea how to find these objects for themselves (with the obvious exceptions of the Sun and Moon). They also need guidance about what equipment, besides a telescope, they will need. This book is written by an expert on the Solar System, who has had a lot of experience with outreach programs, which teach others how to make the most of relatively simple and low-cost equipment. That does not mean that this book is not for serious amateurs. On the contrary, it is designed to show amateur astronomers, in a relatively light-hearted-and math-free way-how to become serious.

Weird Astronomical Theories of the Solar System and Beyond (Paperback, 1st ed. 2016): David Seargent Weird Astronomical Theories of the Solar System and Beyond (Paperback, 1st ed. 2016)
David Seargent
R1,726 Discovery Miles 17 260 Ships in 18 - 22 working days

After addressing strange cosmological hypotheses in Weird Universe, David Seargent tackles the no-less bizarre theories closer to home. Alternate views on the Solar System's formation, comet composition, and the evolution of life on Earth are only some of the topics he addresses in this new work. Although these ideas exist on the fringe of mainstream astronomy, they can still shed light on the origins of life and the evolution of the planets. Continuing the author's series of books popularizing strange astronomy facts and knowledge, Weird Astronomical Theories presents an approachable exploration of the still mysterious questions about the origin of comets, the pattern of mass extinctions on Earth, and more. The alternative theories discussed here do not come from untrained amateurs. The scientists whose work is covered includes the mid-20th century Russian S. K. Vsekhsvyatskii, cosmologist Max Tegmark, British astronomers Victor Clube and William Napier, and American Tom Van Flandern, a specialist in celestial mechanics who held a variety of unusual beliefs about the possibility of intelligent life having come from elsewhere. Despite being outliers, their work reveals how much astronomical understanding is still evolving. Unconventional approaches have also pushed our scientific understanding for the better, as with R.W. Mandl's approaching Einstein with regard to gravitational lensing. Even without full substantiation (and some theories are hardly credible), their hypotheses allow for a new perspective on how the Solar System became what it is today.

'Sarah Cruddas is a gifted writer and Look Up is an inspired book. I am hopeful that we will never stop looking up.' Apollo 11 astronaut Michael Collins Most of us have never been to space. To date, of the more than 100 billion humans that have ever existed, fewer than 600 humans have ever left Earth. But the exploration of space is the most significant thing we will ever do as a species. Sarah Cruddas has been looking to the skies her entire life. Her childhood was spent staring at the Moon and hearing stories of the space race, and she worked in a fruit factory to fund her love of the subject. Her subsequent career studying astrophysics, and becoming a television host and space journalist has seen her report on space exploration and chase launches across the world. In Look Up Sarah explains why she has always been a passionate advocate for why space should matter - to everyone. From our ancestors who first painted patterns of the stars in caves, to the US and Soviet pioneers who first forged a path beyond our planet, Sarah Cruddas explores the stories and sacrifices that humankind has made to understand more about our place in the universe. And even today, when Moon walking and people in space suits seem less relevant to us than climate change and conflicts here on Earth, she shows how everything from medicine to mobile phones is affected by space technology, and how a new generation of entrepreneurs have kick-started a new story with the stars. This is an inspirational and enlightening introduction to the importance of space to everyone, and why we should all learn to Look Up.

R2,168 Discovery Miles 21 680 Ships in 18 - 22 working days

White dwarfs, each containing about as much mass as our Sun but packed into a volume about the size of Earth, are the endpoints of evolution for most stars. Thousands of these faint objects have now been discovered, though only a century ago only three were known. They are among the most common stars in the Milky Way Galaxy, and they have become important tools in understanding the universe. Yet a century ago only three white dwarfs were known. The existence of these stars completely baffled the scientists of the day, and solving the mysteries of these strange objects required revolutionary advances in science and technology, including the development of quantum physics, the construction and utilization of large telescopes, the invention of the digital computer, and the ability to make astronomical observations from space. This book tells the story of the growth in our understanding of white dwarf stars, set within the context of the relevant scientific and technological advances. Part popular science, part historical narrative, this book is authored by one of the astrophysicists who participated directly in uncovering some of the secrets of white dwarf stars.

As our closest stellar companion and composed of two Sun-like stars and a third small dwarf star, Alpha Centauri is an ideal testing ground of astrophysical models and has played a central role in the history and development of modern astronomy-from the first guesses at stellar distances to understanding how our own star, the Sun, might have evolved. It is also the host of the nearest known exoplanet, an ultra-hot, Earth-like planet recently discovered. Just 4.4 light years away Alpha Centauri is also the most obvious target for humanity's first directed interstellar space probe. Such a mission could reveal the small-scale structure of a new planetary system and also represent the first step in what must surely be humanity's greatest future adventure-exploration of the Milky Way Galaxy itself. For all of its closeness, Centauri continues to tantalize astronomers with many unresolved mysteries, such as how did it form, how many planets does it contain and where are they, and how might we view its extensive panorama directly? In this book we move from the study of individual stars to the study of our Solar System and our nearby galactic neighborhood. On the way we will review the rapidly developing fields of exoplanet formation and detection.

R524 Discovery Miles 5 240 Ships in 10 - 15 working days

NASA's ambitious but essential Gemini Program was culminated in November 1966 with the launch of Gemini 12 from Kennedy Space enter's Launch Complex 19. This tenth manned Gemini mission was the final opportunity to develop and practice many new techniques that were integral to the upcoming Apollo program. With the successful conclusion of the Gemini 12 mission, veteran astronaut Command Pilot James Lovell had set another new record with a total of 18 days in space, and Pilot Edwin (Buzz) Aldrin held the EVA duration record with an umbilical EVA at the Agena work station of 2 hours and 9 minutes. In all, three EVA (extra-vehicular activity) sessions were performed during the mission. Going into the Gemini 12 mission, many questions of EVA procedure were still unresolved. In the past, astronauts had expended too much energy simply staying in position. In an effort to better develop techniques and train astronauts, for the first time, underwater simulation was incorporated into EVA training. Using a submerged mock-up of the Gemini-Agena spacecraft, EVA training proceeded almost to the eve of launch.;Training in the neutral-buoyancy underwater simulation allowed the astronauts to practice the entire EVA procedure in a single session - just as they would be required to do in space. This was a major advance over simulated weightlessness in aircraft parabolic flights, which provided only 30 seconds of weightlessness at a stretch. Gemini 12 successfully executed a fuelless station-keeping exercise for 4 hours and 20 minutes with the use of a dacron tether between the Gemini and Agena vehicles. Once the tether had been pulled taut, the reaction control systems for both vehicles were turned off, and the slight difference in the Earth's gravitational effect on the two space vehicles was sufficient to keep the tether taut, so the two spacecraft remained at a constant separation, without the use of any reaction control fuel. Despite mission changes brought on by a radar lock-on failure and by a malfunction of the Agena Primary Propulsion System (PPS), the Gemini 12 mission was considered to be a major success, continuing the success story of the entire Gemini program.;Apollo could take man to the Moon only after Gemini had introduced him to the space environment and taught him how to perform there. CD included.
