A Traveler’s Guide to the Stars

Travis S. Taylor

A message from space leads to a desperate race against time and across space to our nearest stellar neighbor in a new hard science fiction thriller from Travis S. Taylor and Les Johnson. THE ANSWER LIES OUT THERE 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, 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?” About Travis S.

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.

Stellaris: People of the Stars

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 couldnt 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?

Back to the Moon

Gregory Matloff

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.

Going Interstellar

Joseph E. Meany

Two scientists give an enthusiastic, layperson's overview of a new supermaterial now in development that could transform many features of daily life, from creating new conveniences to improving health and safety. 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.

The Superstrong, Superthin, and Superversatile Material That Will Revolutionize the World

Graphene

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.
