THE SECOND TIME AROUND¾IS HARDER . . . Decades after the last footprints were left on the Moon, the U.S. was preparing to return to the Lunar surface in a new class of rockets, when the mission suddenly became much more urgent. It would have to be a rescue mission. Unbeknownst to the rest of the world China had sent its own Lunar expedition. A manned expedition. Until a distress call was received, no human outside of China even knew that the mission was manned¾or that their ship had crash-landed and couldnu0090t take off again. Time was running out, and if the four Chinese astronauts were to be rescued, the American lunar mission would have to launch immediately, with only a skeleton crew. Once the heroic U.S. astronauts were underway the army of engineers and scientists back home had the daunting task of deciding what equipment could be left on the Moon to permit the Lunar lander vehicle vehicle to lift safely from the Moon with the two U.S. astronauts and the four stranded Chinese taikonauts! Could the U.S. mount such a mission successfully¾and would thousands of years of instilled honor _allowÓ the Chinese astronauts to accept a rescue?

ORIGINAL SF TRADE PAPERBACK. Humanity is not alone in the universe. Across the galaxy, a war rages between advanced alien races. And its about to be brought to our doorstep. The year is 2065 and an accidental encounter in space leads to the discovery that we are not alone in the universe—and that our continued existence as a species may be in jeopardy. Chris Holt, working in his office at the Space Resources Corporation, discovers that one of the asteroids he is surveying for mining is actually not an asteroid at all but a derelict spaceship. The word gets out and soon the world''s powers are competing to explore and claim for themselves the secrets that it holds. What they don''t know is that across the galaxy, a war has been underway for millennia. A war between alien civilizations that have very different ideas about what should be done about emerging spacefaring civilizations like our own. The artificial intelligence resident in the derelict Holt discovered has been in our solar system since before the dawn of human civilization, watching, waiting and keeping quiet lest the interstellar war return and wipe out the sentient race that now resides there—humanity. And that war might soon be again coming to our front door. The truth can only be discovered on Methone, a tiny, egg-shaped moon of the planet Saturn. Who will get there first? And will it be in time? p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; color: #454545} At the publisher''s request, this title is sold without DRM (Digital Rights Management).

“Sky Alert! What Happens When Satellites Fail” explores for the first time what our modern world would be like if we were suddenly to lose most, if not all, of our space assets. The author demonstrates humankind’s dependence on space satellites and show what might happen to various aspects of our economy, defense, and daily lives if they were suddenly destroyed. The book opens with a consideration of how our space assets might be lost in the first place: through orbital debris, war, and solar storms. The author then looks at what would happen if our satellites were lost, including the effect on weather forecasting, and the Global Positioning System, explaining GPS in detail and its importance to the military, including spy satellites and military reconnaissance, commerce, civilians, communications and remote sensing – both resource monitoring and locating and environmental monitoring and science. The effects of losing such assets as the International Space Station as well as such research satellites as the Hubble Space Telescope or the Chandra X-Ray Observatory are also considered. Part III of the book looks at how we can protect our satellites, preparing for the worst, reducing the growth and amount of orbital debris, preventing acts of war in space and hardening against space radiation. The book ends on an optimistic note: most spacefaring nations are now working together to develop new technologies to reduce the threat posed by orbital debris and in-space nuclear detonations and treaties exist to limit the development and use of weapons in space. Finally, it is hoped that it will not be long before we will be able to better predict and take precautions against solar storms. The global economy has now become so dependent upon satellites that their loss would be devastating – to the economy, to national security, and potentially, to the day-to-day survival of those who live in the world’s most advanced economies.

A BRILLIANT BLEND OF MILITARY SCIENCE FICTION AND ARTHUR C. CLARKE-LEVEL SPECULATIVE WONDER BY A WORKING SPACE SCIENTIST! NO TIME LIKE THE PRESENT Humanity has finally made it to the stars. Colony worlds thrive and there is general peace among the settled systems. Until now. Matte black ships of an advanced design appear in colonial systems. Their drives and weapons are not extremely advanced beyond their Terran counterparts — just superior enough to be utterly devastating. Colonies and their populations are obliterated. Once settled worlds are rendered radioactive wastelands. Earth herself lies defenseless before the marauding enemy. DEFEND THE SKIES OF EARTH Standing against the invasion are two of humanity’s finest starship captains, Winslow Price of the British Space Navy and Anika Ahuja of the Indian Space Forces. Compatriots. Fierce competitors. Former lovers. Now they are on a quest that will plumb the scientific wells of existence itself, where the primordial knot of spacetime may be unraveling. Price and Ahuja are sworn to do whatever it takes to defend Earth and humanity from ultimate obliteration by an enemy that will not even speak its name. Even if it pushes each to the brink of life and death in battle. Even if it leads each beyond space and time—and to the edge of ultimate possibility!

LOOMING DESTRUCTION FROM SPACE! It''s the beginning of a new golden age of space exploration. Finally, humanity is taking the commercialization of space to the next level—mining asteroids. The new gold rush of the commercial space era has begun. Another commercial venture, an attempt to put a hotel on the Moon, is seeking the space tourism gold of the ultra wealthy. And it seems as if the dream of finally sending people to Mars is finally going to happen using a ship propelled by a powerful nuclear rocket. But space travel isn’t cut and dry, and there is nothing routine about it. In order to mine an asteroid the goal is to bring it closer to Earth, but orbital mechanics are tricky and close to Earth proves to be far too close for comfort—with looming destruction from space about to become a grim reality. Now astronauts, scientists, engineers, and people in all the burgeoning space businesses must team together to stop the asteroid before it is too late for humanity and the planet it calls home.

Time is running out for the inhabitants of Proxima Centauri. Unsettling discoveries there and at Luyten’s star now threaten both Proxima and Earth, in a new hard science fiction thriller from Travis S. Taylor and Les Johnson. First contact with the seemingly impossible human civilization at Proxima Centauri is not going well. The Earth ships sent to render aid have not been able to reverse the contagion ravaging their population and, worse, many Proximans are now wondering if the humans from Earth are there for other, not so charitable, reasons. Can the extinction-level disaster faced at Proxima be reversed by the combined ingenuity of scientists from both worlds working together? Unsettling discoveries in the Proxima Centauri planetary system beg the questions: What if the evil gods depicted in Proxima’s ancient mythologies were real and far more powerful than even the humans from Earth with their late 21st century technologies? Worse, what if their ancient oppressors never truly left? At the publisher''s request, this title is sold without DRM (Digital Rights Management). Praise for Travis S.

This book presents a visionary concept for future development of space travel. It describes the enabling technology for future propulsion concepts and demonstrates how mankind will ‘live off the land in space’ in migration from Earth. For the next few millennia at least (barring breakthroughs), the human frontier will include the solar system and the nearest stars. Will it be better to settle the Moon, Mars, or a nearby asteroid and what environments can we expect to find in the vicinity of nearby stars? These are questions that need to be answered if mankind is to migrate into space.

The year is 2072. At the lunar farside radio observatory, an old school radio broadcast is detected, similar to those broadcast on Earth in the 1940s and early 1950s, but in an unknown language, coming from an impossible source, and originating at an equally impossible location—Proxima Centauri. While the nations of Earth debate making First Contact, they learn that the Proximans are facing an extinction-level disaster, forcing a decision: Will Earth send a ship on a multiyear trip to provide aid? Interstellar travel is not easy, and by traveling at the speeds required to arrive before disaster strikes at Proxima, humans will learn firsthand the effects of Einstein’s Special Relativity and be forced to ponder the ultimate of questions of "Are we alone in the universe?" and "What does it mean to be human?"

We are all touched by death in some way. Les Johnson''s, Tell Everyone, takes you through the jarring experiences of loss and pain that left him without a wife, and almost without his daughter, Heather. The ripples that move through his family after these events are devastating, and his vulnerable retelling makes it relatable. The narrative weaves through a series of events, journals, and letters to his daughter while she was in a coma for weeks. However, the lasting message is the one she brings back with her when she awakens and is determined to tell everyone, of the glad tidings sent directly from Jesus to be shared with all the world. The question of God''s existence, his plan for us, and where we go after this life are beautifully answered in a captivating way. This is a gift in book form, and is addressed to me, you and everyone, so give a gift that lasts, and Tell Everyone.

The reality of sunlight-based sailing in space began in May 2010, and solar sail technology and science have continued to evolve rapidly through new space missions. Using the power of the Sun''s light for regular travel propulsion will be the next major leap forward in our journey to other worlds. This book is the second edition of the fascinating explanation of solar sails, how they work and how they will be used in the exploration of space. Updated with 35% new material, this second edition includes three new chapters on missions operated by Japan and the US, as well as projects that are in progress. The remainder of the book describes the heritage of exploration in water-borne sailing ships and the evolution to space-vehicle propulsion; as well as nuclear, solar-electric, nuclear-electric and antimatter rocket devices. It also discusses various sail systems that may use either sunlight or solar wind, and the design, fabrication and steering challenges associated with solar sails. The first edition was met with overwhelmingly positive reviews, and deemed “a title that needs to be on your shelf if you’re seriously interested in the next step as we move beyond rocketry" (Centauri Dreams, September 2008). Written with a mixed approach, this book appeals to both the general public as well as those with a more scientifically technical background.

What was our planet like in years past? How has our civilization affected Earth and its ecology? Harvesting Space for a Greener Planet, the Second Edition of Paradise Regained: The Regreening of the Earth, begins by discussing these questions, and then generates a scenario for the restoration of Earth. It introduces new and innovative ideas on how we could use the Solar System and its resources for terrestrial benefit. The environmental challenges that face us today cannot be resolved by conservation and current technologies alone. Harvesting Space highlights the risk of humankind’s future extinction from environmental degradation. Population growth, global climate change, and maintaining sustainability of habitats for wildlife are all considered, among other issues. Rather than losing heart, we need to realize that the solutions to these problems lie in being good stewards of the planet and in the development of space. Not only will the solutions offered here avert a crisis, they will also provide the basis for continued technological and societal progress. Tapping the resources of near-Earth asteroids will lead to methods of diverting those asteroids that threaten Earth. Space-based terrestrial power generation systems will work synergistically with Earth-based conservation. This book needs to be read urgently and widely, if we are to save ourselves from environmental disaster, reduce the risk of catastrophic cosmic impacts, and build a prosperous and sustainable future for all the creatures of Earth.

Gritty and scientifically accurate science fiction adventure from New York Times best-selling author Ben Bova and NASA space scientist Les Johnson. The first human mission to Mars meets with near-disaster when a meteoroid strikes the spacecraft, almost destroying it. The ship is too far from Earth to simply turn around and return home. The eight-person crew must ride their crippled ship to Mars while they desperately struggle to survive. On Earth, powerful political forces that oppose human spaceflight try to use the accident as proof that sending humans into space is too dangerous to continue. The whole human space flight program hangs in the balance. And if the astronauts can’t nurse their ship to Mars and back, the voyagers will become either the first Martian colonists—or the first humans to perish on another planet.

About Mars, Inc.: "The Hugo winner returns to his most popular subject: the quest for Mars."—Publishers Weekly About the award winning novels of Ben Bova: “Technically accurate and absorbing . . .”—Kirkus “[Bova is] the science fiction author who will have the greatest effect on the world.”—Ray Bradbury “A masterful storyteller”—Vector “Gives a good read while turning your eyes to what might be in the not so distant future, just like Clarke and Asimov used to do so well.”—SFX

What was our planet like before the advent of our modern civilization? What effects has our civilization had on the planet and its ecological systems? Paradise Regained discusses these questions and then creates a scenario for the re-greening of Earth. The authors introduce new and innovative ideas on how humankind might use the resources of the solar system for terrestrial benefit. Earth would then become a place for a technologically advanced human civilization to live in synchronization, if not in harmony, with the environment which gave us birth. Since the formation of our solar system, the resources and ecological state of Earth have undergone many changes. The environmental challenges facing humanity today, as the authors posit them, will not be resolved simply by conservation and Earth-based alternative technologies. Paradise Regained considers the environmental dilemma and highlights the risk of humankind''s future extinction from environmental degradation. Human population growth, climate change, and the strained sustainability of the few remaining habitats for wild life are all discussed. The authors, however, are not discouraged and offer a potential solution through the development of space. Not only will extraterrestrial resources help avert environmental disaster, but will also provide the basis for continued technological and societal progress. The resources of the solar system will help meet our projected industrial needs and feed our industry once terrestrial sources are depleted. Space-based power generation systems will work synergistically with Earth-based conservation. Paradise Regained concludes with the discussion on how closed ecological systems in space will help us to build a prosperous and sustainable future for all humanity.
