This book presents the history of planetary protection by tracing the responses to the concerns on NASA's missions to the Moon, Mars, Venus, Jupiter, Saturn, and many smaller bodies of our solar system. The book relates the extensive efforts put forth by NASA to plan operations and prepare space vehicles that return exemplary science without contaminating the biospheres of other worlds or our own. To protect irreplaceable environments, NASA has committed to conducting space exploration in a manner that is protective of the bodies visited, as well as of our own planet.

Electrostatic Phenomena on Planetary Surfaces (Hardcover): Carlos I. Calle Electrostatic Phenomena on Planetary Surfaces (Hardcover)
Carlos I. Calle
R3,070 Discovery Miles 30 700 Ships in 10 - 15 working days

The diverse planetary environments in the solar system react in somewhat different ways to the encompassing influence of the Sun. These different interactions define the electrostatic phenomena that take place on and near planetary surfaces. The desire to understand the electrostatic environments of planetary surfaces goes beyond scientific inquiry. These environments have enormous implications for both human and robotic exploration of the solar system. This book describes in some detail what is known about the electrostatic environment of the solar system from early and current experiments on Earth as well as what is being learned from the instrumentation on the space exploration missions (NASA, European Space Agency, and the Japanese Space Agency) of the last few decades. It begins with a brief review of the basic principles of electrostatics.

Annette Froehlich
R4,236 Discovery Miles 42 360 Ships in 12 - 19 working days

This book is the highly anticipated sequel to the previous volume under the same title, dedicated to presenting a diverse range of timely and valuable contributions on the legal and policy related questions evoked by satellite constellations, including emerging mega-constellations. Given the proliferation of activities in the field of satellite constellations, and the critical roles they play in supporting and enabling communication, navigation, disaster monitoring, Earth observation, security and scientific activities, the insights of legal and policy experts from around the world have been gathered in this second volume to help expand the scientific literature in this precious field. Topics range from legal obstacles and opportunities facilitating small satellite enterprise for emerging space actors, international cooperation in the compatibility and interoperability of navigation systems, the designation of satellite constellations as critical space infrastructure, to an analysis of the paradigm shift which has occurred over the last decade to make the proliferation of small satellite constellations possible, and more.

A Brief History of Colour Theory - Foundations of Colour Science (Hardcover, 1st ed. 2021): George Pavlidis A Brief History of Colour Theory - Foundations of Colour Science (Hardcover, 1st ed. 2021)
George Pavlidis
R3,543 Discovery Miles 35 430 Ships in 12 - 19 working days

This book offers a comprehensive introduction in to the various theories of colour and how they developed over the centuries and millennia. As colour is the perception of light by our brains, the book captures not only the physical phenomena but also psychological and philosophical aspects of colours. It starts with ancient studies of Greek philosophers and their insights into light and mirrors, then reviews the theory of colors in the middle ages in Europe and Middle East. The last big part of the book explains the theories of colours by modern scientists and philosophers, starting with Isaac Newton and ending colour schemes of modern digital pictures.

Destination Mars - New Explorations of the Red Planet (Paperback): Rod Pyle Destination Mars - New Explorations of the Red Planet (Paperback)
Rod Pyle; Foreword by Robert Manning
R538 Discovery Miles 5 380 Ships in 12 - 19 working days

In the next decade, NASA, by itself and in collaboration with the European Space Agency, is planning a minimum of four separate missions to Mars. Clearly, exciting times are ahead for Mars exploration. This is an insider's look into the amazing projects now being developed here and abroad to visit the legendary red planet. Drawing on his contacts at NASA and the Jet Propulsion Laboratory, the author provides stunning insights into the history of Mars exploration and the difficulties and dangers of traveling there.
After an entertaining survey of the human fascination with Mars over the centuries, the author offers an introduction to the geography, geology, and water processes of the planet. He then briefly describes the many successful missions by NASA and others to that distant world. But failure and frustration also get their due. As the author makes clear, going to Mars is not, and never will be, easy. Later in the book, he describes in detail what each upcoming mission will involve.
In the second half of the book, he offers the reader a glimpse inside the world of Earth-based "Mars analogs," places on Earth where scientists are conducting research in hostile environments that are eerily "Martian." Finally, he constructs a probable scenario of a crewed expedition to Mars, so that readers can see how earlier robotic missions and human Earth simulations will fit together.
All this is punctuated by numerous firsthand interviews with some of the finest Mars explorers of our day, including Stephen Squyres (Mars Exploration Rover), Bruce Murray (former director of the Jet Propulsion Laboratory), and Peter Smith (chief of the Mars Phoenix Lander and the upcoming OSIRIS-REx missions). These stellar individuals give us an insider's view of the difficulties and rewards of roaming the red planet.
The author's infectious enthusiasm and firsthand knowledge of the international space industry combine to make a uniquely appealing and accessible book about Mars.

Expanding Worldviews: Astrobiology, Big History and Cosmic Perspectives (Hardcover, 1st ed. 2021): Ian Crawford Expanding Worldviews: Astrobiology, Big History and Cosmic Perspectives (Hardcover, 1st ed. 2021)
Ian Crawford
R6,314 Discovery Miles 63 140 Ships in 12 - 19 working days

This book collates papers presented at two international conferences (held at the Australian National University in 2018 and Birkbeck College London in 2019) exploring the relationships between big history and astrobiology and their wider implications for society. These two relatively new academic disciplines aim to integrate human history with the wider history of the universe and the search for life elsewhere. The book will show that, despite differences in emphasis, big history and astrobiology share much in common, especially their interdisciplinary approaches and the cosmic and evolutionary perspectives that they both engender. Specifically, the book addresses the unified, all-embracing, nature of knowledge, the impact of big history on humanity and the world at large, the possible impact of SETI on astrobiology and big history, the cultural signature of Earth's inhabitants beyond our own planet, and the political implications of a planetary worldview. The principal readership is envisaged to comprise scholars working in the fields of astrobiology, big history and space exploration interested in forging interdisciplinary links between these diverse topics, together with educators, and a wider public, interested in the societal implications of the cosmic and evolutionary perspectives engendered by research in these fields.

Why is it dark at night? - Story of dark night sky paradox (Hardcover): Peter Zamarovsky Why is it dark at night? - Story of dark night sky paradox (Hardcover)
Peter Zamarovsky
R800 Discovery Miles 8 000 Ships in 12 - 19 working days

"Why is it dark at night?" might seem a fatuous question at first sight. In reality it is an extremely productive question that has been asked from the very beginning of the modern age, not only by astronomers, for whom it is most appropriate, but also by physicists, philosophers, and even poets. The book you have just opened uses this question as a pretext to relate in the most interesting way the history of human thought from the earliest times to the here and now. The point is that if we want to appreciate the magic power of this ostensibly naive question we need to discover how it fits into the wider context of the natural sciences and learn something of the faltering steps towards an answer. In doing so the author guides us through periods that we regard as the dim and distant past. However, as we start reading these passages we are amazed to discover just how searching were the questions the ancient philosophers asked themselves in spite of their fragmentary knowledge of the universe, and how clairvoyantly they were able to gaze into its mysterious structure. The author goes on to explain very graphically how this increasingly prickly question was tackled by many great men of science. It is bound to come as a surprise that it was not a philosopher, a physicist or an astronomer, but instead the poet Edgar Alan Poe, who hinted at the right answer. I know of no other similar publication that has dealt so graphically or so succinctly with a question which, after four centuries of fumbling and chasing up blind alleys, was only solved in our lifetime.

T. Encrenaz
R4,110 Discovery Miles 41 100 Ships in 10 - 15 working days

This book presents a global and synthetic vision of planetology - the study of objects in the Solar System. In the past several decades, planetology has undergone a real revolution, marked in particular by the discovery of the Kuiper belt beyond Neptune, the discovery of extrasolar planets, and also by the space exploration of ever more distant objects. Today, it is at the crossroads of many disciplines: astronomy, geophysics, geochemistry and biology. The Solar System 2 studies the outer Solar System: satellites and rings of giant planets, small bodies and dwarf planets. It also deals with meteorites and cosmochemistry, as well as the formation and dynamics of the Solar System. It addresses the question of the origin of life and extraterrestrial life, and presents all of the methods in the study of planetology.

Ileana Chinnici, Guy Consolmagno
R3,915 Discovery Miles 39 150 Ships in 12 - 19 working days

Angelo Secchi was a key figure in 19th century science. An Italian Jesuit and scientist, he helped lead the transition from astronomy to astrophysics and left a lasting legacy in the field. Secchi’s spectral classification of stars was a milestone that paved the way for modern astronomical research. He was also a founder of modern meteorology and an innovator in the design and development of new instruments and methods across disciplines.This contributed volume collects together reviews from an international group of historians, scientists and scholars representing the multiple disciplines where Secchi made significant contributions during his remarkable career. It analyzes both his famous and lesser known pioneering efforts with equal vigor, providing a well-rounded narrative of his life’s work. Beyond his scientific and technological work, his role as a Jesuit priest in Rome during the turbulent years of the mid 19th century is also described and placed in the context of his scientific and civic activities.

R586 Discovery Miles 5 860 Ships in 12 - 19 working days

This Model of the Universe concludes the universe to be a spherical region within a much larger region of primordial matter. Primordial Matter is determined to be an endless array of positroniums; matter (+) and antimatter (-) particles, stabilized in and by an equally spaced (.6 cm) hexahedron arrangement. When positron + and electron - particles come in contact they annihilate into photons; when photon concentrations become adequate, they precipitate into corporeal matter of the universe. The initial annihilation started a chain reaction from a single + & - pair which upset the positronium rotation synchronization. Photons from annihilations propagate in all directions and produce more continuing chain reaction annihilations. Outward flowing photon concentrations coalesce and precipitate into subatomic particles. Accretions of particles produce the objects and matter of the universe. The continuing process is called the deflagration wave, because a simple understandable analogy relates to a flame propagating through dry grass: matter is not created nor destroyed; it is only converted from one form of matter into another. All processes in this Model have been proven, and verified; all are consistent with the Laws of Physics.
