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

want to go? How do I do it? Who shall I go with? How much do I
pack? What do I need on the trip? What
Your guide to preparation for an underwater photo safari. The Step
Zero process helps you understand the basics of.. where to go? how
to go? and, who to go with? This book is to help with the very real
problem of how to go about refining your thoughts into a plan that
can be executed toward a SCUBA trip of a lifetime.
An initial top-level view of a Space Elevator concept through space
systems architecture and space systems engineering. A first step in
an aggressive development program to build a Space Elevator.
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
