    All three astronauts were experienced pilots and had dreams of one day walking on the moon, but little did they know, nor did anyone else, that once they entered the spacecraft that cold winter day they would never leave it alive. The Apollo program would be perilously close to failure before it ever got off the ground. But rather than dooming the space program, this tragedy caused the spacecraft to be completely overhauled, creating a stellar flying machine to achieve the program’s primary goal: putting man on the moon. Apollo 1 is a candid portrayal of the astronauts, the disaster that killed them, and its aftermath. In it, readers will learn: How the Apollo 1 spacecraft was doomed from the start, with miles of uninsulated wiring and tons of flammable materials in a pure oxygen atmosphere, along with a hatch that wouldn’t open How, due to political pressure, the government contract to build the Apollo 1 craft went to a bidder with an inferior plan How public opinion polls were beginning to turn against the space control before the tragedy and got much worse after Apollo 1 is about America fulfilling its destiny of man setting foot on the moon. It’s also about the three American heroes who lost their lives in the tragedy, but whose lives were not lost in vain.

    It discusses how to plan your stargazing and what you can see with your eyes, as well as how to choose binoculars and telescopes and what you can see using them. The book also offers seasonal star charts and constellation charts and gives readers specific objects to look for in the sky. This guide from Royal Observatory Greenwich provides all you need to know to get started in stargazing and discover the universe.

    But Beyond Earth does not offer another wide-eyed technology fantasy: instead it is grounded not only in the human capacity for invention and the appeal of adventure but also in the bureaucratic, political, and scientific realities that present obstacles to space travel - realities that have hampered NASA's efforts ever since the Challenger fiasco. In Beyond Earth, the authors offer groundbreaking research and argue persuasively that not Mars but Titan - a moon of Saturn with a nitrogen atmosphere, a weather cycle, and an inexhaustible supply of cheap energy, where we will be able to fly like birds in the minimal gravitational field - offers the most realistic and thrilling prospect of life without support from Earth.

    Everything around us, including matter, is energy. A deep look into the mysteries of the subatomic world – the particles that make up the atom – provides answers to basic questions about how the universe works. To solve the future of mankind’s energy needs we need to understand the basic building blocks of the universe, including the atom and its parts. By exploring the subatomic world we’ll find more answers to our questions about time, forces like gravity and the matter that surrounds us. More importantly, we’ll find new ways to tap into the energy that exists around us to power our growing needs. In a new branch of particle physics, where tiny particles are thought of as energy waves, we find new answers that may help us in our quest to find alternative energy sources.

    Dark matter. These strange and invisible substances don't just sound mysterious: their unexpected appearance in the cosmic census is upending long-held notions about the nature of the Universe. Astronomers have long known that the Universe is expanding, but everything they could see indicated that gravity should be slowing this spread. Instead, it appears that the Universe is accelerating its expansion and that something stronger than gravity--dark energy--is at work. In Einstein's Telescope Evalyn Gates, a University of Chicago astrophysicist, transports us to the edge of contemporary science to explore the revolutionary tool that unlocks the secrets of these little-understood cosmic constituents. Based on Einstein's theory of general relativity, gravitational lensing, or "Einstein's Telescope," is enabling new discoveries that are taking us toward the next revolution in scientific thinking--one that may change forever our notions of where the Universe came from and where it is going.

    We just want to lie down, look up, and understand the heavens above. The National Geographic Backyard Guide to the Night Sky shows us how.Authors Howard Schneider and Patricia Daniels take an expert but easygoing approach that doesn’t overwhelm—it invites. Ten chapters cover everything a beginning stargazer will need to know, from understanding the phases of the moon to picking Mars out of a planetary lineup to identifying the kinds of stars twinkling in the constellations.Throughout the book, star charts and tables present key facts in an easy-to-understand format, sidebars and fact boxes present illuminating anecdotes and fun facts to sweep us swiftly into the stardust, and by the time we realize we’ve been schooled in solid science we’re too engrossed to object.Along with practical advice and hands-on tips to improve observation techniques, the guide includes an appendix full of resources—from books and web sites to lists of astronomy clubs and associations to local planetariums and museums. This indispensable book guides us on a new path into the night sky, truly one of the greatest shows on Earth.

    A starry night is one of nature's most magical wonders, yet in our artificially lit world, three-quarters of Americans' eyes never switch to night vision, and most no longer experience true darkness. In The End of Night, Paul Bogard restores awareness of the spectacularly primal, wildly dark night sky and how it has influenced the human experience across everything from science to art.From Las Vegas's Luxor Beam (the brightest single spot on this planet) to nights so starlit the sky looks like snow, Bogard blends personal narrative, natural history, science, and history to shed light on the importance of darkness--what we've lost, what we still have, and what we might regain--and the simple ways we can reduce the brightness of our nights tonight.

    Buzz Aldrin, one of the first moonwalkers, has no shortage of these ideas. And in Mission to Mars he treats us to how, when, and why we should travel there." -Neil deGrasse TysonLegendary "space statesman" Buzz Aldrin speaks out as a vital advocate for the continuing quest to push the boundaries of the universe as we know it. As a pioneering astronaut who first set foot on the moon during mankind's first landing of Apollo 11--and as an aerospace engineer who designed an orbital rendezvous technique critical to future planetary landings--Aldrin has a vision, and in this book he plots out the path he proposes, taking humans to Mars by 2035.Foreword by Andrew AldrinChapter 1: The View from Air Force OneChapter 2: Time for Decision-makingChapter 3: Your Space: Building the Business CaseChapter 4: Dreams of My MoonChapter 5: Voyage to ArmageddonChapter 6: The March to MarsChapter 7: Homesteading the Red PlanetChapter 8: The Clarion Call

    Nobody is perfect. And that includes five of the greatest scientists in history—Charles Darwin, William Thomson (Lord Kelvin), Linus Pauling, Fred Hoyle, and Albert Einstein. But the mistakes that these great luminaries made helped advance science. Indeed, as Mario Livio explains, science thrives on error, advancing when erroneous ideas are disproven.As a young scientist, Einstein tried to conceive of a way to describe the evolution of the universe at large, based on General Relativity—his theory of space, time, and gravity. Unfortunately he fell victim to a misguided notion of aesthetic simplicity. Fred Hoyle was an eminent astrophysicist who ridiculed an emerging theory about the origin of the universe that he dismissively called “The Big Bang.” The name stuck, but Hoyle was dead wrong in his opposition.They, along with Darwin (a blunder in his theory of Natural Selection), Kelvin (a blunder in his calculation of the age of the earth), and Pauling (a blunder in his model for the structure of the DNA molecule), were brilliant men and fascinating human beings. Their blunders were a necessary part of the scientific process. Collectively they helped to dramatically further our knowledge of the evolution of life, the Earth, and the universe.
