Earth in Human Hands
For the first time in Earth's history, our planet is experiencing a confluence of rapidly accelerating changes prompted by one species: humans. Climate change is only the most visible of the modifications we've made--up until this point, inadvertently--to the planet. And our current behavior threatens not only our own future but that of countless other creatures. By comparing Earth's story to those of other planets, astrobiologist David Grinspoon shows what a strange and novel development it is for a species to evolve to build machines, and ultimately, global societies with world-shaping influence. Without minimizing the challenges of the next century, Grinspoon suggests that our present mom...
Lonely Planets
PEN Literary Award Winner: “The best, most entertaining examination of the possibility of other life in the universe since [Carl] Sagan’s best work.” —Boulder Daily Camera It’s been decades since Carl Sagan first addressed the general public about the possibility of extraterrestrial life from a scientist’s perspective. We’ve learned a lot in those years, and now planetary scientist David Grinspoon investigates the big questions: How widespread are life and intelligence in the cosmos? Is life on Earth an accident, or in some sense the “purpose” of this universe? And how can we, working from the Earth-centric definition of “life,” even begin to think about the varieties o...
Venus Revealed
Until very recently, all we really knew about Venus, our nearest planetary neighbor, was that it was roughly the same size and mass as the earth and was surrounded by a thick atmosphere. Then, in 1989, American scientists launched Magellan—the spacecraft that would revolutionize our vision of this mysterious planet. Venus Revealed is the first book to explain the breathtaking results of this mission, which unveiled a Venusian world of active volcanoes, shining mountains, and river valleys carved by torrents of flowing lava. At one time, Venus may have even had a wet, temperate climate, much like Earth's. What happened to turn it into a hostile, burning acid world? The answer could very well help us solve some of our most pressing environmental problems—from global warming to acid rain. In Venus Revealed, David Grinspoon eloquently argues that studying our exotic twin will inevitable teach us more about ourselves.
The Planet Venus
Shrouded by the thick clouds of hot, dense atmosphere, the planet Venus - Earth's closest neighbour in space - remained mysterious until recent decades. Today, with data from contemporary observations and from Russian and American spacecraft, Venus has moved into sharper focus. This comprehensive book provides an up-to-date and detailed analysis of the nature of Venus. The authors, experts in planetary science from Russia and the United States, examine all the principal aspects of Venus, with particular attention paid to the planet's formation, the development of a runaway greenhouse effect, and Venus' evolution into a planet completely different from others in our solar system. Integrating data from Galileo, Magellan, Pioneer-Venus, Venera sand other space missions, this book summarizes the history of Venus, covers the atmosphere, geomorphology and tectonic history of the planet, and considers its geology.
Chasing New Horizons
Called "spellbinding" (Scientific American) and "thrilling...a future classic of popular science" (PW), the up close, inside story of the greatest space exploration project of our time, New Horizons’ mission to Pluto, as shared with David Grinspoon by mission leader Alan Stern and other key players. On July 14, 2015, something amazing happened. More than 3 billion miles from Earth, a small NASA spacecraft called New Horizons screamed past Pluto at more than 32,000 miles per hour, focusing its instruments on the long mysterious icy worlds of the Pluto system, and then, just as quickly, continued on its journey out into the beyond. Nothing like this has occurred in a generation—a raw explo...
Venus Revealed
"Early robot probes sent by Russian and American scientists had given us some tantalizing but fragmentary glimpses of the surface and atmosphere, hinting at some of the most exotic conditions seen in the solar system. Magellan showed a planet full of beautiful landscapes, some eerily familiar and some completely unexpected - a world of active volcanoes, shining mountains, and even river valleys carved by torrents of flowing lava. Venus may once have had a wet, temperate, comfortable climate, much like Earth's. What happened to turn it into a hostile, burning, acid world? Our twin has important tales to tell us regarding several of Earth's most pressing environmental problems, including ozone...
Towards Understanding the Climate of Venus
ESA’s Venus Express Mission has monitored Venus since April 2006, and scientists worldwide have used mathematical models to investigate its atmosphere and model its circulation. This book summarizes recent work to explore and understand the climate of the planet through a research program under the auspices of the International Space Science Institute (ISSI) in Bern, Switzerland. Some of the unique elements that are discussed are the anomalies with Venus’ surface temperature (the huge greenhouse effect causes the surface to rise to 460°C, without which would plummet as low as -40°C), its unusual lack of solar radiation (despite being closer to the Sun, Venus receives less solar radiation than Earth due to its dense cloud cover reflecting 76% back) and the juxtaposition of its atmosphere and planetary rotation (wind speeds can climb up to 200 m/s, much faster than Venus’ sidereal day of 243 Earth-days).
Psychedelic Drugs Reconsidered
First published in 1979, Psychedelic Drugs Reconsidered is regarded by many as the most comprehensive, accurate, and accessible analysis of psychedelic drugs for the general reader. It records the extensive history of scientific research on, and societal experience with, psychedelic drugs. The Lindesmith Center reprint edition features a new introduction by the authors on recent developments in psychedelic research, as well as a preface by Dr. Ethan Nadelmann, director of the Lindesmith center.
Planetary Crusts
This comprehensive reference volume surveys the development of crusts on solid planets and satellites in the solar system.
