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! TAKE THE BATTLE TO THE STARS About Mission to Methone: "The spirit of Arthur C. Clarke and his contemporaries is alive and well in Johnson's old-fashioned first-contact novel, set in 2068. . . . includes plenty of realistic detail and puts fun new spins on familiar alien concepts. . . .

What if you discovered an infinitesimally thin material capable of conducting electricity, able to suspend millions of times its own weight, and yet porous enough to filter the murkiest water? And what if this incredible substance is created from the same element that fills the common pencil? That's graphene--a flat, two-dimensional, carbon-based molecule with a single sheet measuring only one atom thick. In this layperson's introduction to this revolutionary substance, a physicist and a chemist explain how graphene was developed, discuss the problems in scaling up production for large-scale commercial use, and forecast the potentially transformative effects of incorporating graphene into everyday life. Recent research developments include adding graphene to Silly Putty to make extremely sensitive and malleable medical sensors and compressing and fusing flakes of graphene to create a three-dimensional material that's ten times stronger than steel. This widely adaptable substance promises to change the way we interact with smartphones, laptops, information storage, and even condoms. It may also enable significant improvements to air purification, water filtration technologies, and drug delivery. This entertaining and widely accessible book offers a fascinating look into one of the most exciting developments in materials science in recent decades.

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? About Mission to Methone: "The spirit of Arthur C. Clarke and his contemporaries is alive and well in Johnson's old-fashioned first-contact novel, set in 2068.... includes plenty of realistic detail and puts fun new spins on familiar alien concepts.... There's a great deal here for fans of early hard SF."--Publishers Weekly "With equal parts science fiction and international intrigue....an exciting, fast-paced read that you will not want to put down."--Booklist About Rescue Mode by Ben Bova and Les Johnson: "... a suspenseful and compelling narrative of the first human spaceflight to Mars."--Booklist

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.

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.

"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.
