    The accompanying CD-ROM features a special student version of the award-winning virtual planetarium software Starry Night plus software animations and videos, all illustrations from the text, interactive Q&A and exercises, and supplementary resources. Material can be updated periodically from the Freeman Web site. www.whfreeman.com/astronomy. There is an online study guide offering a CD-Web guide, chapter objectives, key terms, review questions, Starry Night observations exercises and online tutorials.

    The book covers the fundamental aspects of analysis and design, and also discusses practical requirements such as safety, feasibility, and economy of structural elements. It is hoped that the text would also serve as an introduction to postgraduate students. Practicing civil engineers and consultants who need a review of current practice and current IS specifications will also find it useful as a reference.

    

    

    The future is here: Civilians are launching into orbit. How to Build Your Own Spaceship takes readers on a fun and quirky trip to the forefront of commercial space travel-the latest technology, the major business players, and the personal and financial benefits that are ripe for the picking. Science-writer Piers Bizony's breadth of knowledge, quick wit, and no-nonsense explanations of the hard science in this emerging arena will satisfy even the most dedicated space fanatics. With practical advice (from picking the best jet fuel to funding your own fleet of space crafts), unbelievable space facts, and fascinating photos, Bizony's user-friendly guide to blasting off is a must-have ticket to the final frontier.

    As huge as the Pantheon of Rome and as heavy as the Statue of Liberty, this magnificent instrument is so precisely built that its seventeen-foot mirror was hand-polished to a tolerance of 2/1,000,000 of an inch. The telescope's construction drove some to the brink of madness, made others fearful that mortals might glimpse heaven, and transfixed an entire nation. Ronald Florence weaves into his account of the creation of "the perfect machine" a stirring chronicle of the birth of Big Science and a poignant rendering of an America mired in the depression yet reaching for the stars.

    They and several heroes of future space flight take on and do the impossible, build a program to explore and settle the red planet in a very short time period. Along the way they dig up old and invent new technology to overcome the many problems facing them. Mario and his wife are forced to take his brother's place when he is viciously attacked moments before launch. The team must overcome many problems, weather, radiation, and politics to get the colony started. Along the way they must divert an asteroid which has some far reaching consequences. Mankind will never be the same after the Mario brothers come on the scene!

    However, after researching the facts, the author did something he rarely does. He made a complete about-face on his views regarding The Hollow Moon Theory! Just why did he do this? For a good reason: because the evidence to support the idea of our Moon being hollow was far greater than he had ever suspected and comes from a wide variety of scientific disciplines and sources. The Author discovered there is also a veritable avalanche of evidence for the existence of aliens being on or in a hollow Moon. If you have ever wondered if the Moon might just be hollow, after reading this book, For The Moon Is Hollow And Aliens Rule The Sky, you will wonder no more. This book includes evidence for: -- Recorded historical evidence for our Moon not always having been in our skies. -- Discusses the truth of the Spaceship Moon Theory (Hollow Moon Theory). -- Names the five main theories of our Moon’s origin and what’s wrong with them. -- Shows evidence for not just one, but possibly two hollow moons! -- Develops a new theory, that of the Diaspora of alien civilizations to the stars. -- Bizarre physical oddities about our Moon. -- Strange evidence for alien structures on the Moon. -- Weird events show evidence for aliens in space, in our skies, and on the Moon. -- Convincing evidence and arguments as to just why the Moon is hollow. -- Documented account of aliens and our astronauts. -- An in-depth discussion of just what all this may mean for humanity? And more! The author builds his case for the idea of our Moon being hollow step by easy step, and provides information from a wide variety of sources to support this theory. Is our Moon hollow? Do aliens dwell within it? Do such strange beings rule our sky? The answers all lie in For The Moon Is Hollow And Aliens Rule The Sky, a cutting edge look at all the latest ideas, theories, and facts to support them, as well as including a new theory of just why it may well be that all intelligent civilizations might take to the stars in hollowed-out worlds! And what fear drives them to do so!

    A mindless alien race has swept across the colonies, consuming structures and people along the way. As humanity stands on the brink of destruction, we have one hope to preserve what’s left of our culture and very lives. The Passage.One of the greatest scientific achievements of humanity, a gateway that will hyper-accelerate our faster than light drives so we can cover an unimaginable distance. A new home waits beyond, one far from our aggressors. But can we escape the desolation of our old empire before it’s too late?

    He signed up to escape the grinding poverty of the Housing Blocks. And the unlikely friends envisioned boring, peacetime careers as shuttle pilots. The Tahni Imperium had other ideas... Caught in the desperate fury of the Battle for Mars, the two young pilots wind up the last defense against an alien armada, but their war is just beginning. Recruited to fly the Fleet's newest weapon in this new war, they take the fight deep into the heart of the Imperium and battle not just against the enemy but against incompetent leadership and ineffectual tactics. Can the unconventional strategies of a pair of hotshot young pilots change the course of the war? And when the time comes that a choice has to be made between duty to command and loyalty to a friend, which of the two will be willing to make one last flight alone... From the author of the bestselling Drop Trooper Military Sci-Fi Series comes another tale of war against an alien menace known as the Tahni. Perfect for fans of Jay Allan, Jasper T. Scott, and Scott Bartlett. (less)

    

    Now, using never-before-published quotes taken from his in-depth interviews with twenty-three of the twenty-four Apollo lunar astronauts, Chaikin and his collaborator, Victoria Kohl, have created an extraordinary account of the lunar missions. In Voices from the Moon the astronauts vividly recount their experiences in intimate detail; their distinct personalities and remarkably varied perspectives emerge from their candid and deeply personal reflections. Carefully assembled into a narrative that reflects the entire arc of the lunar journey, Voices from the Moon captures the magnificence of the Apollo program like no other book. Paired with their own words are 160 images taken from NASA's new high-resolution scans of the photos the astronauts took during the missions. Many of the photos, which are reproduced with stunning and unprecedented detail, have rarely-if ever-been seen by the general public. Voices from the Moon is an utterly unique chronicle of these defining moments in human history.
