While the Moon was once thought to hold the key to space exploration, in recent decades, the U.S. has largely turned its sights toward Mars and other celestial bodies instead. In The Value of the Moon, lunar scientist Paul Spudis argues that the U.S. can and should return to the moon in order to remain a world leader in space utilization and development and a participant in and beneficiary of a new lunar economy. Spudis explores three reasons for returning to the Moon: it is close, it is interesting, and it is useful. The proximity of the Moon not only allows for frequent launches, but also control of any machinery we place there. It is interesting because recorded deep on its surface and in its craters is the preserved history of the moon, the sun, and indeed the entire galaxy. And finally, the moon is useful because it is rich with materials and energy. The moon, Spudis argues, is a logical base for further space exploration and even a possible future home for us all. Throughout his work, Spudis incorporates details about man's fascination with the moon and its place in our shared history. He also explores its religious, cultural, and scientific resonance and assesses its role in the future of spaceflight and our national security and prosperity.
NASA has been in the news lately for reasons beyond theexciting discoveries of various and vast quantities of wateron the Moon. Unfortunately, the long, drawn outrepositioning of our national space program has brought thespace community to loggerheads, leaving the future of theU.S. manned space program in jeopardy. The upheaval ......

Concepts" is a search for theism's roots - coined prototheism - a science of religion. Its notion is: Belief in God is a misconception of the Life Urge emerging from deep in human nature. "Concepts" traces Life's trajectory - from Earth's origin, to consciousness, to today's runaway material culture.
An understandable perspective on the types of space propulsion systems necessary to enable low-cost space flights to Earth orbit and to the Moon and the future developments necessary for exploration of the solar system and beyond to the stars.
The updated and expanded third edition of this book focuses on the multi-disciplinary coupling between flight-vehicle hardware alternatives and enabling propulsion systems. It discusses how to match near-term and far-term aerospace vehicles to missions and provides a comprehensive overview of the subject, directly contributing to the next-generation space infrastructure, from space tourism to space exploration. This holistic treatment defines a mission portfolio addressing near-term to long-term space transportation needs covering sub-orbital, orbital and escape flight profiles. In this context, a vehicle configuration classification is introduced covering alternatives starting from the dawn of space access. A best-practice parametric sizing approach is introduced to correctly design the flight vehicle for the mission. This technique balances required mission with the available vehicle solution space and is an essential capability sought after by technology forecasters and strategic planners alike.

The bestselling Invitation to Oceanography continues to provide a modern, comprehensive, and student-friendly introduction to this fascinating field. Spanning the four major divisions of ocean science—geology, chemistry, physics, and biology— it is an ideal text for majors and nonmajors alike. The Seventh Edition has been updated with sophisticated and cutting-edge graphics and photos throughout, and includes trending content on climate change, Superstorm/Hurricane Sandy, and the tsunami in Japan. Updated and expanded feature boxes reinforce key concepts and support knowledge building, and additional information on current research and the clinical and practical applications of oceanography contextualize scientific ideas within a real-world framework. Accessible yet substantive, Invitation to Oceanography, Seventh Edition is the ideal resource for anyone diving into the thrilling depths of the world’s oceans.
This impressive scientific resource presents up-to-date information on ten thousand years of volcanic activity on Earth. In the decade and a half since the previous edition was published new studies have refined assessments of the ages of many volcanoes, and several thousand new eruptions have been documented. This edition updates the book’s key components: a directory of volcanoes active during the Holocene; a chronology of eruptions over the past ten thousand years; a gazetteer of volcano names, synonyms, and subsidiary features; an extensive list of references; and an introduction placing these data in context. This edition also includes new photographs, data on the most common rock types forming each volcano, information on population densities near volcanoes, and other features, making it the most comprehensive source available on Earth’s dynamic volcanism.
Seesengood traces the life and impact of Paul – one ofChristianity’s most influential figures – through themajor periods Christian history. Exploring the changinginterpretations of Paul and his work, the author throws new lighton his writings and on religious history. Offers a unique, insightful journey through the many and variedinterpretations of Paul’s life and work over 2,000 years– from the Gnostic controversy, to Luther and theReformation, to contemporary debates over religion and science Explains Paul’s pivotal role within Christian history,and how his missionary journeys, canonized epistles and theologicalinsights were cornerstones of the early Church and central to theformation of Christian doctrine Argues that each new interpretation of Paul is the result of afresh set of cultural, social and ideological circumstances –and so questions whether it is ever possible to discover the realPaul
