England appearances, a courtroom drama and a spell in prison were
just the start. He later returned to Sheffield Wednesday's first
team before going into management and guiding Matlock town to the
FA Trophy, but since retiring he has faced an increasing battle
with Alzheimers. Setting the Record Straight lifts the lid on what
was termed 'the biggest sports scandal of the century' and all that
happened afterwards for this outstanding footballer.
In the last year, the International Space Elevator Consortium
assessed that basic technological needs can be met with current
capabilities: and, each segment of the Space Elevator
Transportation System is ready for engineering validation. Because
of the availability of a new material as a potential Space Elevator
tether, the community strongly believes that a Space Elevator will
be initiated in the near term. Included in the book is a series of
appendices that are tremendous references to the status of the
space elevator today. Included are a lexicon of space elevator
terms, over 750 references in the bibliography, short descriptions
of eight ISEC year-long studies and two IAA 4-year studies on space
elevators, as well as a summary of over 20 Architectural Notes
covering the development of space elevator technologies.
The study team took on the challenge of expanding the "body of
knowledge" pertaining to the Apex and Geosynchronous elements of
the Space Elevator. A special effort was made to describe the
elements in the context of an entire Space Elevator. The report
complements and expands earlier ISEC Space Elevator reports on the
Climber, Operations Concept, Architectures & Roadmaps, and
Earth Port. To do so, we have established; 1.A robust set of
definitions within the Geosynchronous and Apex Regions, and 2.The
Strategic Approach to Architectural Development of a Space Elevator
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
