The International Space Elevator Consortium has created this position paper as a recognition that the space debris problem is an engineering one and can be mitigate. The question: "Will space debris be a show stopper for space elevators?" is answered emphatically - NO! The mitigation concepts presented change the issue from a perceived problem to an engineering concern; but, by no means is it a significant threat. This pamphlet illustrates how the development office for a future space elevator can attack this problem, predict probabilities of collision, and convert the concern into another manageable engineering problem.

This history of SAFSP is dedicated to all those men and women who fought the Cold War, in silence - from above. No organization is better at gathering overhead intelligence than the U.S. National Reconnaissance Office (NRO). Today's NRO grew out of 3 organizations: AF, CIA, and Navy. The AF office for satellite reconnaissance was called the Secretary of Air Force's Office of Special Projects [SAFSP]. This monograph describes the birth of Air Force satellite reconnaissance. When SAFSP was created in response to Presidential recognition of a national imperative, 4 tenets captured the sense of urgency: direct access to national leadership, covert management/operations, highest national priority, and rapid procurement. In addition, 3 management principles led to SAFSP's success over 30+ years of providing reconnaissance intelligence: strong dedication to mission, empowerment at all levels, and reporting by exception.

The subject selected for this 2013 study is the Space Elevator Tether Climber. The objective of the one year study was to survey current concepts and technologies related to tether climbers, identify critical issues, questions, and concerns, assess their impact on the development of space elevators, and project towards the future. The following are a few of the conclusions: * The study used the concept of "constant power" as a baseline because of its ability to lower design requirements on the tether climber. * The mass breakout of 6 MT for a climber and 14 MT for customer payloads seems feasible. The estimate is that with a travel time of one week to GEO seven tether climbers can be on a tether simultaneously. * The communication architecture should be integrated into the space elevator infrastructure and nodal layout. * Solar power, as the sole source, appears achievable. * The use of laser power as the sole source also seems achievable.

While the development of Space Elevator tethers and climbers is a daunting task, their operation will leverage 50 years of satellite operations. This leads to the conclusion: Operations for a Space Elevator Have NO Showstoppers Have Reasonable Costs Meet the Challenges i?

Today's tech-savvy and digitally connected students present a new challenge for today's school librarians. This book offers the 21st-century tools and know-how necessary for educators to appeal to and challenge students to learn-and to want to learn. What are the best ways to motivate students to become engaged and develop a passion for learning? Can appealing to their desire for socialization and constant communication-attributes of their lives outside of education-via the integration of cutting-edge technologies and "new media" in the library or classroom serve to ignite creativity, curiosity, and critical thinking? This book shows how you can make use of non-traditional tools such as popular social networks, collaborative technologies, and cloud computing to teach information and communications technologies integrated with the school curriculum to improve student learning-and demonstrates how these same technologies can help you measure skills and mastery learning. The book provides an easy-to-follow blueprint for using collaborative techniques, innovation, and teaching for creativity to achieve the new learning paradigm of self-directed learning, such as flipping the classroom or library. Readers of this book will find concrete, step-by-step examples of proven lesson plans, collaborative models, and time-saving strategies for the successful integration of American Association of School Librarians (AASL) standards. The authors-both award-winning teachers-explain the quantitatively and qualitatively measurable educational value of using these technologies for core curricular and information and communications technologies instruction, showing that they both enhance student learning outcomes and provide data for measuring their impact on learning. Includes innovative, practical lesson plans designed to promote problem solving skills, flexible thinking, and metacognition as well as an extensive bibliography of additional resources Addresses how to analyze quantitative and qualitative data to perform the assessment necessary to improve learning outcomes Provides essential information and guidance for K-12 librarians, technology integration teachers, and educators as well as school administrators Addresses key aspects of learning such as critical thinking, inquiry, learning spaces, blended learning, engagement, motivation, and Common Core State Standards (CCSS)
