An astonishing exploration of planet formation and the origins of life by one of the world's most innovative planetary geologists. In 1959, the Soviet probe Luna 3 took the first photos of the far side of the moon. Even in their poor resolution, the images stunned scientists: the far side is an enormous mountainous expanse, not the vast lava-plains seen from Earth. Subsequent missions have confirmed this in much greater detail. How could this be, and what might it tell us about our own place in the universe? As it turns out, quite a lot. Fourteen billion years ago, the universe exploded into being, creating galaxies and stars. Planets formed out of the leftover dust and gas that coalesced into larger and larger bodies orbiting around each star. In a sort of heavenly survival of the fittest, planetary bodies smashed into each other until solar systems emerged. Curiously, instead of being relatively similar in terms of composition, the planets in our solar system, and the comets, asteroids, satellites and rings, are bewitchingly distinct. So, too, the halves of our moon. In When the Earth Had Two Moons, esteemed planetary geologist Erik Asphaug takes us on an exhilarating tour through the farthest reaches of time and our galaxy to find out why. Beautifully written and provocatively argued, When the Earth Had Two Moons is not only a mind-blowing astronomical tour but a profound inquiry into the nature of life here-and billions of miles from home.

'An astronomical Sherlock Holmes' WASHINGTON POST 'Visionary' STEPHEN GREENBLATT 'Compelling . . . The book is not so much a claim for one object as an argument for a more open-minded approach to science - a combination of humility and wonder' NEW STATESMAN Harvard's top astronomer takes us inside the mind-blowing story of the first interstellar visitor to our solar system In late 2017, scientists at a Hawaiian observatory glimpsed a strange object soaring through our inner solar system. Astrophysicist Avi Loeb conclusively showed it was not an asteroid; it was moving too fast along a strange orbit, and leaving no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization. In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his theory and its profound implications: for science, for religion, and for the future of our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars-and to think critically about what's out there, no matter how strange it seems.

Dynamic Mars: Recent and Current Landscape Evolution of the Red Planet presents the latest observations, interpretations, and explanations of geological change at the surface or near-surface of this terrestrial body. These changes raise questions about a decades-old paradigm, formed largely in the aftermath of very coarse Mariner-mission imagery in the 1960s, suggesting that much of the interesting geological activity on Mars occurred deep in its past, eons ago. The book includes discussions of (1) Mars' ever-changing atmosphere and the impact of this on the planet's surface and near-surface; (2) the possible involvement of water in relatively new, if not contemporary, gully-like flows and slope streaks (i.e. recurring slope lineae); and (3) the identification of a broad suite of agents and processes (i.e. glacial, periglacial, aeolian, meteorological, volcanic, and meteoric) that are actively revising surface and near-surface landscapes, landforms, and features on a local, regional, and hemispheric scale. Highly illustrated and punctuated by data from the most recent Mars missions, Dynamic Mars is a valuable resource for all levels of research in the geological history of Mars, as well as of the three other terrestrial planets.

Some might think that the 27 thousand tons of material launched by earthlings into outer space is nothing more than floating piles of debris. However, when looking at these artifacts through the eyes of historians and anthropologists, instead of celestial pollution, they are seen as links to human history and heritage.

Space: The New Frontier for Archeologists

Handbook of Space Engineering, Archaeology and Heritage, published this month by CRC Press Taylor and Francis Group, brings together 43 anthropologists, historians, physicists, and engineers, a scientific team as culturally diverse as the crew of any science fiction cruiser. They offer a range of novel historical and technological perspectives on humankind s experience in space. This ambitious work presents an informative, thought-provoking, and educational text that discusses the evolution of space engineering, spacecraft reliability and forensics, field techniques, and mission planning, as well as space programs for the future. The book is edited by a pair of scientists from different sides of the campus: Ann Garrison Darrin, aerospace engineer and NASA veteran and Beth Laura O Leary, anthropologist and member of the World Archaeological Congress Space Heritage Task Force.

The handbook delves into the evolution of space archaeology and heritage, including the emerging fields of Archaeoastronomy, Ethnoastronomy, and Cultural Astronomy. It also covers space basics and the history of the space age from Sputnik to modern day satellites. It discusses the cultural landscape of space, including orbital artifacts in space, as well as objects left on planetary surfaces and includes a look at the culture of Apollo as a catalog of manned exploration of the moon. It also considers the application of forensic investigation to the solving of cold case mysteries including failed Mars mission landing sites and lost spacecraft, and even investigates the archaeology of the putative Roswell UFO crash site and appraises material culture in science fiction.

Synthesizing concepts from all branches of astro-sciences into one, the book is a valuable reference for researchers in astrogeology, astrophysics, cosmochemistry, astrobiology, astronomy, and other space science fields, helping users better understand the intersection of these sciences.

A sweeping tour of the infrared universe as seen through the eyes of NASA's Spitzer Space Telescope Astronomers have been studying the heavens for thousands of years, but until recently much of the cosmos has been invisible to the human eye. Launched in 2003, the Spitzer Space Telescope has brought the infrared universe into focus as never before. Michael Werner and Peter Eisenhardt are among the scientists who worked for decades to bring this historic mission to life. Here is their inside story of how Spitzer continues to carry out cutting-edge infrared astronomy to help answer fundamental questions that have intrigued humankind since time immemorial: Where did we come from? How did the universe evolve? Are we alone? In this panoramic book, Werner and Eisenhardt take readers on a breathtaking guided tour of the cosmos in the infrared, beginning in our solar system and venturing ever outward toward the distant origins of the expanding universe. They explain how astronomers use the infrared to observe celestial bodies that are too cold or too far away for their light to be seen by the eye, to conduct deep surveys of galaxies as they appeared at the dawn of time, and to peer through dense cosmic clouds that obscure major events in the life cycles of planets, stars, and galaxies. Featuring many of Spitzer's spectacular images, More Things in the Heavens provides a thrilling look at how infrared astronomy is aiding the search for exoplanets and extraterrestrial life, and transforming our understanding of the history and evolution of our universe.

This book is primarily concerned with fundamental components of solar physics, terrestrial geophysics and general climate issues. Phenomena such as planetary influence on solar variability, the Sun's irradiance and solar wind continue to fascinate members of the scientific community. What is more astounding is the way in which our planet reacts to these occurrences; climate changes, sea levels, tides, ocean circulation and geomagnetism, all caused by the processes mentioned above. The pages that follow analyze and calculate the relationships between solar causation and terrestrial reaction. This work begins with a foreword from Walter Cunningham, the famous Apollo 7 astronaut who in 1968 took part in the first manned space flight. Section A is devoted to the concept of planetary-solar-terrestrial interaction and driving forces that represent a break-through in science. The book begins with a high-lightening of records indicating a planetary influence on solar activity and continues with multiple discussions of terrestrial variables. It concludes with an account of the physics behind the changes in the Sun and in the Earth. Section B presents the remarkable decision to terminate the journal of pattern recognition in physics because the authors concluded that we are now on our way into a new grand solar minimum. This inspires doubt in an accelerating global warming. In the name of science and ethics, five papers respond to this "modern book-burning". Section C is devoted to general conclusions, co-authored by 19 eminent scientists in the field of solar physics, geophysics, geology, hydrology and climatology. It also includes a short note on concluding editorial views.

Chinas position in the world has been evolving. It seeks increased influence and independence from foreign powers with the ultimate goal of preserving Chinas sovereignty, independence, territorial integrity, and political system. Over the long term, China seeks to transform the international system to better suit its interests, but seeks to integrate itself into the existing international system over the short term with the goal of reshaping the Asia-Pacific political environment into one in which its interests must be given greater attention. Chinas pursuit of space power is intended to support this strategy. China views the development of space power as a necessary move for a country that wants to strengthen its national power. Indeed, Chinas goal is to become a space power on par with the United States and to foster a space industry that is the equal of those in the United States, Europe, and Russia. This book begins with an elaborate discussion on China's progress in space technologies and examines the implications it has on the United States. Furthermore, this title reviews the evolution of Chinas military thinking and the changed role of space within that context. It briefly examines Chinas space capabilities and development before discussing its concepts for military space operations and concludes with future Chinese space operations.

We all know the names: Grissom, Armstrong, Cernan-legends of the space age whose names resonate with people around the world and whose deeds need no introduction. We know less about the men who led the organization that planned and began the US exploration of space: the National Aeronautics and Space Administration (NASA). Thomas O. Paine grew up an ordinary boy in northern California during the Great Depression of the 1930s. He would go on to serve as NASA's third administrator, leading the space agency through the first historic missions that sent astronauts on voyages away from Earth. On his watch, seven Apollo flights orbited our planet and five reached our moon. From those missions came the first of twelve men to walk on the moon. Years later, in 1985, the Reagan administration would call on Paine again to chair the nation's first-ever National Commission on Space. The Paine Commission Report of 1986 challenged twenty-first-century America to "lead the exploration and development of the space frontier, advancing science, technology, and enterprise, and building institutions and systems that make accessible vast new resources and support human settlements beyond Earth orbit, from the highlands of the Moon to the plains of Mars." In Piercing the Horizon, Sunny Tsiao masterfully delivers new insights into the behind-the-scenes drama of the space race. Tsiao examines how Paine's days as a World War II submariner fighting in the Pacific shaped his vision for the future of humankind in space. The book tells how Paine honed his skills as a pioneering materials engineer at the fabled postwar General Electric Company in the 1950s, to his dealings inside the halls of NASA and with Johnson, Nixon, and later, the Reagan and Bush administrations.As robotic missions begin leaving the earth, Tsiao invites the reader to take another look at the plans that Paine articulated regarding how America could have had humans on Mars by the year 2000 as the first step to the exploration of deep space. Piercing the Horizon provides provocative context to current conversations on the case for reaching Mars, settling our solar system, and continuing the exploration of space.
