Book Description
Alien warnings embedded in our crop circles have gone unnoticed, until now. Governments around the globe race against time to evacuate billions of inhabitants from the planet due to the discovery that Earth will be destroyed in the year 2012, a mere eight years away. Where would we go? How would we get there? Who would be left behind? And why is one race of aliens plotting to keep us here? These are just a few of the questions and obstacles faced on this galactic odyssey by our trio of heroes in Escape 2 Earth. Matt, Will, and Art are reluctantly drawn into an adventure by a secret alien organization that will unlock the mysteries of Stonehenge, the White Pyramid of China, the Mayan calendar, and the Great Sphinx in a scramble to help save the human race. This epic quest for Earth's survival takes you from the powdery pink morning skies on the planet Lazon to the subterranean cities under planet Vada and the Whistling forest. The battle between good and evil that began long ago in a far off galaxy is now being played out with the survival of mankind at stake. This sci-fi story is laced with a touch of telepathy, deception, and a murder or two. Discover the hidden alien base deep in the dark murky depths of the Marinas Trench, watch as the aliens prepare to celebrate at the Festival of Life. Who will survive the race to escape this doomed planet? It is anybody's guess. Who will Escape to Earth?

Escape from Earth
Author: Fraser MacDonald
Publisher: PublicAffairs
ISBN: 1610398696
Category : Science
Languages : en
Pages : 442
Book Description
The long-buried truth about the dawn of the Space Age: lies, spies, socialism, and sex magick. Los Angeles, 1930s: Everyone knows that rockets are just toys, the stuff of cranks and pulp magazines. Nevertheless, an earnest engineering student named Frank Malina sets out to prove the doubters wrong. With the help of his friend Jack Parsons, a grandiose and occult-obsessed explosives enthusiast, Malina embarks on a journey that takes him from junk yards and desert lots to the heights of the military-industrial complex. Malina designs the first American rocket to reach space and establishes the Jet Propulsion Laboratory. But trouble soon finds him: the FBI suspects Malina of being a communist. And when some classified documents go missing, will his comrades prove as dependable as his engineering? Drawing on an astonishing array of untapped sources, including FBI documents and private archives, Escape From Earth tells the inspiring true story of Malina's achievements--and the political fear that's kept them hidden. At its heart, this is an Icarus tale: a real life fable about the miracle of human ingenuity and the frailty of dreams.

Advanced Thermodynamics Engineering, Second Edition
Author: Kalyan Annamalai
Publisher: CRC Press
ISBN: 1439805725
Category : Science
Languages : en
Pages : 1144
Book Description
Advanced Thermodynamics Engineering, Second Edition is designed for readers who need to understand and apply the engineering physics of thermodynamic concepts. It employs a self-teaching format that reinforces presentation of critical concepts, mathematical relationships, and equations with concrete physical examples and explanations of applications—to help readers apply principles to their own real-world problems. Less Mathematical/Theoretical Derivations—More Focus on Practical Application Because both students and professionals must grasp theory almost immediately in this ever-changing electronic era, this book—now completely in decimal outline format—uses a phenomenological approach to problems, making advanced concepts easier to understand. After a decade teaching advanced thermodynamics, the authors infuse their own style and tailor content based on their observations as professional engineers, as well as feedback from their students. Condensing more esoteric material to focus on practical uses for this continuously evolving area of science, this book is filled with revised problems and extensive tables on thermodynamic properties and other useful information. The authors include an abundance of examples, figures, and illustrations to clarify presented ideas, and additional material and software tools are available for download. The result is a powerful, practical instructional tool that gives readers a strong conceptual foundation on which to build a solid, functional understanding of thermodynamics engineering.

Off Armageddon Reef

Category : Fiction

Pages : 804
Book Description
Humanity pushed its way to the stars - and encountered the Gbaba, a ruthless alien race that nearly wiped us out. Earth and her colonies are now smoldering ruins, and the few survivors have fled to distant, Earth-like Safehold, to try to rebuild. But the Gbaba can detect the emissions of an industrial civilization, so the human rulers of Safehold have taken extraordinary measures: with mind control and hidden high technology, they've built a religion in which every Safeholdian believes, a religion designed to keep Safehold society medieval forever. 800 years pass. In a hidden chamber on Safehold, an android from the far human past awakens. This "rebirth" was set in motion centuries before, by a faction that opposed shackling humanity with a concocted religion. Via automated recordings, "Nimue" - or, rather, the android with the memories of Lieutenant Commander Nimue Alban - is told her fate: she will emerge into Safeholdian society, suitably disguised, and begin the process of provoking the technological progress which the Church of God Awaiting has worked for centuries to prevent. Nothing about this will be easy. To better deal with a medieval society, "Nimue" takes a new gender and a new name, "Merlin." His formidable powers and access to caches of hidden high technology will need to be carefully concealed. And he'll need to find a base of operations, a Safeholdian country that's just a little more freewheeling, a little less orthodox, a little more open to the new. And thus Merlin comes to Charis, a mid-sized kingdom with a talent for naval warfare. He plans to make the acquaintance of King Haarahld and Crown Prince Cayleb, and maybe, just maybe, kick off a new era of invention. Which is bound to draw the attention of the Church...and, inevitably, lead to war. It's going to be a long, long process. And David Weber's epic Off Armageddon Reef is can't-miss sci-fi.

Fast Interplanetary Missions with Low-thrust Propulsion Systems
Author: W. E. Moeckel
Publisher:
ISBN:
Category : Propulsion systems
Languages : en
Pages : 40
Book Description
A simple family of indirect-transfer trajectories between circular orbits is used to evaluate the mass ratio required to complete round-trip interplanetary missions using low-thrust propulsion systems. These trajectories, although not optimum, yielded very substantial reductions in total round-trip time for Mars missions with moderate increases in initial weight. For a powerplant specific weight [alpha] of 10 pounds per kilowatt of jet power, trip times were reduced from 1200 to 600 days, for a typical manned mission, with an initial weight increase of a factor of two. Comparison with a nuclear rocket with 1000-second specific impulse indicated that the electric-propulsion system required less initial weight for trip times as low as 550 days with [alpha]=10 and as low at 400 days with [alpha]=5 pounds per kilowatt. Further weight reductions would be expected with more nearly optimum trajectories.

Comparison of Trajectory Profiles and Nuclear-propulsion-module Arrangements for Manned Mars and Mars-Venus Missions
Author: Edward A. Jr Willis
Publisher:
ISBN:
Category : Nuclear propulsion
Languages : en
Pages : 36
Book Description
A brief comparison is made between opposition class (with three impulse return), conjunction class, Venus swing-by to Mars and Mars-Venus double stopover trajectories. Vehicle configurations based on NERVA-I engines of varying life and restart capability are considered. It is found that the opposition and Venus swingby trajectories to Mars yield competitive mission performance; the double stopover entails about 30-percent penalties in initial mass and trip time; and that the minimum-weight vehicle uses a single, restartable engine.
