A brief guide to the real science of interstellar travel With known
exoplanets now numbering in the thousands and initiatives like 100
Year Starship and Breakthrough Starshot advancing the idea of
interstellar travel, the age-old dream of venturing forth into the
cosmos and perhaps even colonizing distant worlds may one day
become a reality. A Traveler's Guide to the Stars reveals how. Les
Johnson takes you on a thrilling tour of the physics and
technologies that may enable us to reach the stars. He discusses
the latest exoplanet discoveries, promising interstellar missions
on the not-so-distant horizon, and exciting new developments in
space propulsion, power, robotics, communications, and more. But
interstellar travel will not be easy, and it is not for the faint
of heart. Johnson describes the harsh and forbidding expanse of
space that awaits us, and he addresses the daunting challenges-both
human and technological-that we will need to overcome in order to
realize tomorrow's possibilities. A Traveler's Guide to the Stars
is your passport to the next great frontier of human discovery,
providing a rare inside look at the remarkable breakthroughs in
science and technology that will help tomorrow's space travelers
chart a course for the stars.
Traveling to the stars will be difficult, but not, perhaps, the
most difficult part. What about when we get to another star? What
then? Will the planets be immediately habitable? Not likely. Will
those who undertook the journey be able to easily turn arou
NO TIME LIKE THE PRESENT Humanity has finally made it to the stars.

Interstellar Travel: Purpose and Motivations is a comprehensive,
technical look at the necessary considerations for interstellar
travel addressed by leading experts in the field, from scientists
studying possible destinations (exoplanets) and the vast distances
between, to those concerned with building institutions and
capabilities in society that could sustain such endeavors. In
addition to the technical, medical, and anthropological aspects of
deep space travel, the ethics and morality of spreading Earth-based
life to other worlds is also examined. In the first book of a
three-book compilation, Interstellar Travel: Purpose and
Motivations offers in-depth, up-to-date and realistic technical and
scientific considerations in the pursuit of interstellar travel and
is an integral reference for scientists, engineers, researchers and
academics working on, or interested in, space development and space
technologies. With a renewed interest in space exploration and
development evidenced by the rise of the commercial space sector
and various governments now planning to send humans back to the
moon and to Mars, so also is interest in taking the next steps
beyond the Solar System and to the ultimate destination - planets
circling other stars.
Interstellar Travel: Propulsion, Life Support, Communications, and
the Long Journey addresses the technical challenges that must be
overcome to make such journeys possible. Leading experts in the
fields of space propulsion, power, communication, navigation, crew
selection, safety and health provide detailed information about
state-of-the-art technologies and approaches for each challenge,
along with possible methods based on real science and engineering.

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.
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.
"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.
Human civilization has evolved to the point at which we can
consider tapping space resources and expanding beyond Earth's
atmosphere. The Introduction surveys possible motivations for
large-scale human emigration to space. Since our early ancestors
began to move out of Africa, humans have constantly expanded their
range. Today, the pattern of human settlement extends from pole to
pole. Humans regularly visit the upper troposphere and ocean floor
and technology has enabled a few to even reside above the
atmosphere in space stations.
For the next few millennia at least (barring breakthroughs), the
human frontier will include the solar system and the nearest stars.
Will it better to settle the Moon, Mars, or a nearby asteroid and
what environments can we expect to find in the vicinity of nearby
stars are questions that need to be answered if mankind is to
migrate into space.

The answer lies out there. The year is 2072. At the lunar farside

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.

A Tale of Titanic Lifeboat # 15 Bert Johns was a quiet young man.
He came to America to start a new life. His story, although new to
us, has been told for the past 100 years in his hometown of Hardin,
Lebanon. His family relates that he was deeply affected by the
sinking of Titanic, as we can all imagine. He was consumed by
thoughts of it every day of the 40 years he lived after Titanic. He
was a very sad man. He told his story to very few people, for he
was harassed and tormented for saving himself in a lifeboat half
full of people. He moved to Marlette, Michigan after working three
years in factories in Port Huron. Marlette must have seemed as far
away from Titanic as any place in the world. I was told the story
of Bert Johns and Titanic by friends, Marlette attorney, Ward
Atkins, and Bert's friend and business associate, Earl Ingram back
in 1985. He requested of these friends that his story not be told
until 50 years after his death, for the sake of his family. Bert
died in 1952. A hundred years have passed since the sinking of the
mighty Titanic. She lies now at the bottom of the sea. Bert's story
can now be told. I am proud to be able to tell it. "The Ropes of
the Past Ring The Bells of the Future ..." -Carl Sandburg
