The Cassini-Huygens mission has revolutionized our knowledge of the Saturn system and revealed surprising places in the solar system where life could potentially gain a foothold—bodies we call ocean worlds.Since its arrival in 2004, Cassini–Huygens has been nothing short of a discovery machine, captivating us with data and images never before obtained with such detail and clarity. Cassini taught us that Saturn is a far cry from a tranquil lone planet with delicate rings. Now, we know more about Saturn’s chaotic, active, and powerful rings, and the storms that rage beneath. Images and data from Saturn’s moons Titan and Enceladus hint at the possibility of life never before suspected. The rings of Saturn, its moons, and the planet itself offer irresistible and inexhaustible subjects for intense study. As the Cassini mission comes to a dramatic end with a fateful plunge into Saturn on Sept. 15, 2017, scientists are already dreaming of going back for further study. Over a period of 13 years, Cassini has captured about 450,000 spectacular images within the Saturn system, providing new views of the “lord of the rings” and a plethora of iconic images. To honor the art and science of Cassini, this book was developed collaboratively by a team from NASA’s Planetary Science Division (PSD), NASA’s Jet Propulsion Laboratory (JPL), and the Lunar and Planetary Institute (LPI). While these images represent the tip of the iceberg—each telling a story about Saturn and its mysterious moons—our hope is that the mission will inspire future artists and explorers. The sheer beauty of these images is surpassed only by the science and discoveries they represent.This book was developed collaboratively by the National Aeronautics and Space Administration (NASA) including NASA’s Planetary Science Division (PSD), NASA’s Jet Propulsion Laboratory (JPL), and the Lunar and Planetary Institute (LPI), operated for NASA by Universities Space Research Association.CreditNASA / Jet Propulsion Laboratory - Caltech / Lunar and Planetary Institute

    Few people get the experience of seeing the world from outer space--and no one has taken as many pictures of Earth from above as Terry Virts. Celebrated NASA astronaut, pilot of the space shuttle, crew member on Soyuz, and commander of the International Space Station, Virts has spent more than 200 days in space--and very few of those days went by without his reaching for his camera. Now as never before, Virts shares the astronaut's view of the world, offering astounding aerial views of our planet and the vastness that surrounds it. The colors, shapes, details--and the stories they tell--are endlessly fascinating. Virts's book marries his stunning photographs with glimpses of everyday life in orbit. And amid this amazing show of Earth spectacles, he reflects on how the astronaut's point of view has shaped his life and spirit. Filled with magnificent photographs that will astonish and inspire, this book--and its intrepid author--becomes our guide to a new way of looking at the world.

    Now, to space!’ – Hannah Fry‘Few people are more knowledgeable, celebratory and witty about space travel than Dallas Campbell.’ – Adam RutherfordNeed some space? For almost all human history we’ve been firmly rooted to the Earth. And, sure, it's got some good things going for it: nice views, friendly inhabitants, good coffee. Air. But what if you want to get off?   Whether you've got itchy feet and need a bit of a break, or you’re looking for a complete change of scene, this book has all the information you'll need to leave, with FREE expert advice from the men and woman who can actually make it happen.   Do I need a passport? How do I know if I have the right stuff? Can I take my dog? What spacesuit do I need? Where am I going to go? What am I going to eat?   As well as being a deeply impractical guide to getting off the planet, this is an eclectic and beautifully illustrated mix-tape of space travel stories – both real and imagined. From the migrating lunar geese that flew us to the moon in the 1600’s, to Elon Musk’s wild plan to get humans to Mars en masse in the future; from the history of early rocket science to the Soviet tortoises that secretly won the space race.   A collection for anyone who has looked up in wonder at the stars... And then wondered how to get there.‘The next best thing to actually heading off into space.’ – Jim Al-Khalili‘Few people are more knowledgeable, celebratory and witty about space travel than Dallas Campbell.’ – Adam Rutherford‘If, like me, you dream of going into space, this is definitely the place to start the journey.’ – Dan Snow‘A must have volume for astronauts and armchair astronauts alike.’ – Helen Sharman OBE‘Funny, factual and beautiful.’ – Shaun Keavney‘Read it, make notes, and be ready when the day comes.’ – Helen Czerski

    Yet every year, recovery from droughts and floods costs billions of dollars, and we spend billions more on dams, diversions, levees, and other feats of engineering. These massive projects not only are risky financially and environmentally, they often threaten social and political stability. What if the answer was not further control of the water cycle, but repair and replenishment? Sandra Postel takes readers around the world to explore water projects that work with, rather than against, nature’s rhythms. In New Mexico, forest rehabilitation is safeguarding drinking water; along the Mississippi River, farmers are planting cover crops to reduce polluted runoff; and in China, “sponge cities” are capturing rainwater to curb urban flooding. Efforts like these will be essential as climate change disrupts both weather patterns and the models on which we base our infrastructure. We will be forced to adapt. The question is whether we will continue to fight the water cycle or recognize our place in it and take advantage of the inherent services nature offers. Water, Postel writes, is a gift, the source of life itself. How will we use this greatest of gifts?

    This book addresses that oversight and enlightens readers about the most important aspect of one of the greatest challenges of our time. The global environment is under massive stress from centuries of human industrialization. The projections regarding climate change for the next century and beyond are grim. The impact this will have on human health is tremendous, and we are only just now discovering what the long-term outcomes may be. By weighing in from a physician's perspective, Jay Lemery and Paul Auerbach clarify the science, dispel the myths, and help readers understand the threats of climate change to human health. No better argument exists for persuading people to care about climate change than a close look at its impacts on our physical and emotional well-being. The need has never been greater for a grounded, informative, and accessible discussion about this topic. In this groundbreaking book, the authors not only sound the alarm but address the health issues likely to arise in the coming years.--Laurie Garrett, Pulitzer Prize-winning writer; author of I Heard the Sirens Scream "Publishers Weekly, Starred Review"

    Now it's one of the fastest-growing fields in astronomy with thousands of exoplanets discovered to date, and the number is rising fast.These new-found worlds are more alien than anything in fiction. Planets larger than Jupiter with years lasting a week; others with two suns lighting their skies, or with no sun at all. Planets with diamond mantles supporting oceans of tar; possible Earth-sized worlds with split hemispheres of perpetual day and night; waterworlds drowning under global oceans and volcanic lava planets awash with seas of magma. The discovery of this diversity is just the beginning. There is a whole galaxy of possibilities. The Planet Factory tells the story of these exoplanets. Each planetary system is different, but in the beginning most if not all young stars are circled by clouds of dust, specks that come together in a violent building project that can form colossal worlds hundreds of times the size of the Earth. The changing orbits of young planets risk dooming any life evolving on neighbouring worlds or, alternatively, can deliver the key ingredients needed to seed its beginnings. Planet formation is one of the greatest construction schemes in the Universe, and it occurred around nearly every star you see. Each results in an alien landscape, but is it possible that one of these could be like our own home world?

    Written by two well-known planetary scientists, this text explains the physical and chemical principles of atmospheric evolution and planetary atmospheres, in the context of how atmospheric composition and climate determine a planet's habitability. The authors survey our current understanding of the atmospheric evolution and climate on Earth, on other rocky planets within our Solar System, and on planets far beyond. Incorporating a rigorous mathematical treatment, they cover the concepts and equations governing a range of topics, including atmospheric chemistry, thermodynamics, radiative transfer, and atmospheric dynamics, and provide an integrated view of planetary atmospheres and their evolution. This interdisciplinary text is an invaluable one-stop resource for graduate-level students and researchers working across the fields of atmospheric science, geochemistry, planetary science, astrobiology, and astronomy.

    Whether and where there was gold to be mined redefined land, mineral, and water laws. Where rain falls (and where it doesn’t) determines whose fruit grows on trees and whose appears on slot machines. All this emerges from the geology of the range and how it changed history, and in so doing, changed the country.  The Mountains That Remade America combines geology with history to show how the particular forces and conditions that created the Sierra Nevada have effected broad outcomes and influenced daily life in the United States in the past and how they continue to do so today. Drawing connections between events in historical geology and contemporary society, Craig H. Jones makes geological science accessible and shows the vast impact this mountain range has had on the American West.

    Featuring an outstanding and never-before-published collection of HiRISE high-resolution color images with explanatory captions in twenty-four languages, this book offers a unique volume produced from an active NASA mission. Mars enthusiasts will appreciate these perfect snapshots of our current understanding of Mars, with soon-to-be classic pictures that have come to define our vision of the Red Planet. These images and their interpretations will be held as a yardstick for future exploration as we learn more about the surface and geologic processes of the fourth planet from the Sun. With tantalizing and artistic glimpses at actively eroding slopes, impact craters, strange polar landscapes, avalanches, and even spectacular descent pictures of probes like the Phoenix Lander and the Mars Science Laboratory, we see what researchers are seeing. Through vivid and beautiful images, this book underscores the need for such a camera on future orbiters, especially as more landing missions are planned. Mars: The Pristine Beauty of the Red Planet provides a stunning keepsake of one of humanity’s greatest accomplishments in space travel.

    Allow yourself to be taken back into deep geologic time when strange creatures roamed the Earth and Western North America looked completely unlike the modern landscape.  Volcanic islands stretched from Mexico to Alaska, most of the Pacific Rim didn’t exist yet, at least not as widespread dry land; terranes drifted from across the Pacific to dock on Western Americas’ shores creating mountains and more volcanic activity.  Landscapes were transposed north or south by thousands of kilometers along huge fault systems.  Follow these events through paleogeographic maps that look like satellite views of ancient Earth.  Accompanying text takes the reader into the science behind these maps and the geologic history that they portray.  The maps and text unfold the complex geologic history of the region as never seen before.

    Satellites play an important role in collecting climate data, offering comprehensive global coverage that can't be matched by in situ observation. And yet, as Mariel Borowitz shows in this book, much satellite data is not freely available but restricted; this remains true despite the data-sharing advocacy of international organizations and a global open data movement. Borowitz examines policies governing the sharing of environmental satellite data, offering a model of data-sharing policy development and applying it in case studies from the United States, Europe, and Japan—countries responsible for nearly half of the unclassified government Earth observation satellites.Borowitz develops a model that centers on the government agency as the primary actor while taking into account the roles of such outside actors as other government officials and non-governmental actors, as well as the economic, security, and normative attributes of the data itself. The case studies include the U.S. National Aeronautics and Space Administration (NASA) and the U.S. National Oceanographic and Atmospheric Association (NOAA), and the United States Geological Survey (USGS); the European Space Agency (ESA) and the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT); and the Japanese Aerospace Exploration Agency (JAXA) and the Japanese Meteorological Agency (JMA). Finally, she considers the policy implications of her findings for the future and provides recommendations on how to increase global sharing of satellite data.

    It provides enormous environmental benefits by keeping streams and rivers flowing. But a growing global population, widespread use of industrial chemicals, and climate change threaten this vital resource. Groundwater depletion and contamination has spread from isolated areas to many countries throughout the world. In this accessible and timely book, hydrology expert William M. Alley and science writer Rosemarie Alley sound the call to protect groundwater.   Drawing on examples from around the world, including case studies in the United States, Canada, Australia, India, and Sub-Saharan Africa, the authors examine groundwater from key scientific and socioeconomic perspectives. While addressing the serious nature of groundwater problems, the book includes stories of people who are making a difference in protecting this critical resource.

    Scientists found evidence for this theory in a "crater of doom" on the Yucat�n Peninsula, showing that our planet had once been a target in a galactic shooting gallery. In Cataclysms, Michael R. Rampino builds on the latest findings from leading geoscientists to take "neocatastrophism" a step further, toward a richer understanding of the science behind major planetary upheavals and extinction events.Rampino recounts his conversion to the impact hypothesis, describing his visits to meteor-strike sites and his review of the existing geological record. The new geology he outlines explicitly rejects nineteenth-century "uniformitarianism," which casts planetary change as gradual and driven by processes we can see at work today. Rampino offers a cosmic context for Earth's geologic evolution, in which cataclysms from above in the form of comet and asteroid impacts and from below in the form of huge outpourings of lava in flood-basalt eruptions have led to severe and even catastrophic changes to the Earth's surface. This new geology sees Earth's position in our solar system and galaxy as the keys to understanding our planet's geology and history of life. Rampino concludes with a controversial consideration of dark matter's potential as a triggering mechanism, exploring its role in heating Earth's core and spurring massive volcanism throughout geologic time.
