This peer-reviewed book provides detailed insights into how space
and its applications are, and can be used to support the
development of the full range and diversity of African societies,
as encapsulated in the African Union's Agenda 2063. Following on
from Part 1, which was highly acclaimed by the space community, it
focuses on the role of space in supporting the UN Sustainable
Development Goals in Africa, but covers an even more extensive
array of relevant and timely topics addressing all facets of
African development. It demonstrates that, while there have been
significant achievements in recent years in terms of economic and
social development, which have lifted many of Africa's people out
of poverty, there is still a great deal that needs to be done to
fulfill the basic needs of Africa's citizens and afford them the
dignity they deserve. To this end, space is already being employed
in diverse fields of human endeavor to serve Africa's goals for its
future, but there is much room for further incorporation of space
systems and data. Providing a comprehensive overview of the role
space is playing in helping Africa achieve its developmental
aspirations, the book will appeal to both students and
professionals in fields such as space studies, international
relations, governance, and social and rural development.
Astronomy in the Inca Empire was a robust and fundamental practice.
The subsequent Spanish conquest of the Andes region disrupted much
of this indigenous culture and resulted in a significant loss of
information about its rich history. Through modern
archaeoastronomy, this book helps recover and interpret some of
these elements of Inca civilization. Astronomy was intricately
woven into the very fabric of Andean existence and daily life.
Accordingly, the text takes a holistic approach to its research,
considering first and foremost the cultural context of each
astronomy-related site. The chapters necessarily start with a
history of the Incas from the beginning of their empire through the
completion of the conquest by Spain before diving into an
astronomical and cultural analysis of many of the huacas found in
the heart of the Inca Empire. Over 300 color images-original
artwork and many photos captured during the author's extensive
field research in Machu Picchu, the Sacred Valley, Cusco, and
elsewhere-are included throughout the book, adding visual insight
to a rigorous examination of Inca astronomical sites and history.
This thesis describes the application of state-of-the-art
high-energy X-ray studies to the astronomical quest for
understanding obscured active galactic nuclei (AGN). These AGN are
supermassive black holes growing by accretion of matter located in
the nuclei of galaxies. The material that feeds these black holes
also obscures them from view, rendering them challenging to study.
It is possible to study them by effectively 'X-raying' galactic
nuclei to peer through these obscuring veils. Beginning with the
proof-of-concept application of novel X-ray Monte Carlo codes to
the Nuclear Spectroscopic Telescope ARray (NuSTAR) spectrum of a
known heavily obscured AGN, the thesis establishes the relevant
parameters that characterise the AGN spectrum and central black
hole growth rate. Next the largest sample of known heavily obscured
AGN is compiled, finding the strength of a prominent iron spectral
feature to weaken with AGN power. This is puzzling, and suggests
that there may be more hidden AGN than previously thought. Finally
by combining an all-sky infrared selection with NuSTAR follow-up,
new heavily obscured AGN are identified. Obscuration emits infrared
radiation, meaning that the infrared-selected AGN catalogue should
be representative of the underlying AGN population. The absence of
such representative catalogues has continually plagued cosmological
studies, and the resultant obscured AGN fraction will be strongly
constraining for AGN models.
NASA SP 2010-4319. NASA History Series. This scholarly look at the
Altitude Wind Tunnel covers the transformations the wind tunnel
made in its long history from a wind tunnel doing full-scale
testing for wartime applications, to a vacuum chamber supporting
the Vision for Space Exploration, and even a brief period as home
to Mercury astronaut training. The book also addresses the attempts
to resurrect the facility and its eventual decommissioning and
demolition.
The review papers in this volume provide an in-depth examination of
complex astrophysical phenomena of star formation via
multi-wavelength observations and modeling. Among the fundamental
issues discussed in the book are: The role of gravity and
magnetized turbulence in the formation and evolution of molecular
clouds The stellar feedback (supernovae, HII regions, winds, cosmic
rays) in regulating star formation The origin of the stellar
initial mass function and its universality across various
environments Jets, magnetic fields and high energy particles in
stellar clusters The origin of the first stars and black holes The
goal of these papers is to review the major processes governing
star formation and to investigate how they are interlinked. In
doing so, they provide an in-depth look at the tremendous
theoretical and observational progress that has been made in the
recent past and also outline future perspectives. Previously

Formation"
The 2020 International Conference on Uncertainty Quantification
& Optimization gathered together internationally renowned
researchers in the fields of optimization and uncertainty
quantification. The resulting proceedings cover all related aspects
of computational uncertainty management and optimization, with
particular emphasis on aerospace engineering problems. The book
contributions are organized under four major themes: Applications
of Uncertainty in Aerospace & Engineering Imprecise
Probability, Theory and Applications Robust and Reliability-Based
Design Optimisation in Aerospace Engineering Uncertainty
Quantification, Identification and Calibration in Aerospace Models
This proceedings volume is useful across disciplines, as it brings
the expertise of theoretical and application researchers together
in a unified framework.
Much has been written in the West on the history of the Soviet
space program, but few Westerners have read direct first-hand
accounts of the men and women who were behind the many Russian
accomplishments in exploring space. The memoir of academician Boris
Chertok, translated from the original Russian, fills that gap.
Chertok began his career as an electrician in 1930 at an aviation
factory near Moscow. Thirty years later, he was deputy to the
founding figure of the Soviet space program, the mysterious "Chief
Designer" Sergey Korolev. Chertok's 60-year-long career and the
many successes and failures of the Soviet space program constitute
the core of his memoirs, Rockets and People. In these writings,
spread over four volumes (volumes two through four are
forthcoming), academician Chertok not only describes and remembers,
but also elicits and extracts profound insights from an epic story
about a society's quest to explore the cosmos. This book was edited
by Asif Siddiqi, a historian of Russian space exploration, and
General Tom Stafford contributed a foreword touching upon his
significant work with the Russians on the Apollo-Soyuz Test
Project. Overall, this book is an engaging read while also
contributing much new material to the literature about the Soviet
space program.

held on October 28-29, 2008 at NASA. Scholars turn a critical eye
toward NASA's first 50 years.
Ensuring a Sustainable World
We are on the cusp of a 21st century Age of Discovery - about the
Earth, about the solar system, about ourselves and our place in the
cosmos - with new opportunities to address age-old challenges, as
well as to meet emerging ones. While advancing into space is not
the answer to these challenges, it can be a significant and vital
part of an answer, providing benefits that other answers cannot.
With a thoughtful program of space activities we can ensure a
sustainable world with abundant energy and resources, a high
standard of living, and unprecedented opportunity for all. However,
to become a widely held vision that we must pursue now, rather than
just interesting ideas for some distant time, we need to see space
as integral to addressing societal issues. This book shows a way to
do that.
There are abundant opportunities in space, but the only way to
utilize them is to go there. As our ancestors crossed thresholds to
inhabit the Earth, we can cross the threshold to become a
space-faring civilization, and realize the benefits of those
efforts. Space is only 100 km (62 miles) away, you just need to
look up.
What people are saying:
"Crossing the Threshold is a carefully considered, insightful
narrative that should interest anyone and everyone who cares about
the future of spaceflight." - Homer Hickam, author of Rocket
Boys/October Sky
"Crossing the Threshold is a NASA veteran's thoughtful and
considered look at the value of space travel and exploration, not
only for satisfying humanity's seemingly unquenchable thirst for
adventure and knowledge but also for preparing and positioning us
technically to begin to solve some of the greatest problems facing
us on Earth." - Henry Petroski, Aleksandar S. Vesic Professor of
Civil Engineering and Professor of History, Duke University, author
of The Essential Engineer: Why Science Alone Will Not Solve Our
Global Problems
Crossing the Threshold "is very impressive for the range of ideas
and technical specifics." - Felix Godwin, author of The Exploration
of the Solar System.
This book shares a range of new and diverse insights on On-Orbit
Servicing (OOS), and examines its implications especially from
political, legal, economic, and security perspectives. OSS has been
evolving rapidly and presents both challenges and opportunities,
such as in-space repairs, refuelling, refurbishment of spacecraft
and servicing satellites, which could play a critical role in
extending satellite lifecycles, while also representing a valuable
next step in debris mitigation. At the same time, many legal
questions have arisen in connection with OOS: the need to prevent
hostile actions under the pretext of OSS; the distinction between
governmental and non-governmental OOS operators; the status of
re-worked and recycled space objects; the issue of control in terms
of operations performed in orbit, i.e., in the international
sphere; the status of objects manufactured in orbit and applicable
law, including liability and registration; and the impacts on
insurance law and risk management. Finally, the book examines the
implications of OOS for emerging space actors in the Global South,
and recommends a paradigm shift to help developing countries fully
recognise the necessity and urgency of being involved in
discussions on OSS, as opposed to leaving it up to the developed
space actors. This book will be of great interest to practitioners,
academics, and students working in the space sector and related
fields.
This book traces the development of Kepler's ideas along with his
unsteady wanderings in a world dominated by religious turmoil.
Johannes Kepler, like Galileo, was a supporter of the Copernican
heliocentric world model. From an early stage, his principal
objective was to discover "the world behind the world", i.e. to
identify the underlying order and the secrets that make the world
function as it does: the hidden world harmony. Kepler was driven
both by his religious belief and Greek mysticism, which he found in
ancient mathematics. His urge to find a construct encompassing the
harmony of every possible aspect of the world - including
astronomy, geometry and music - is seen as a manifestation of a
deep human desire to bring order to the apparent chaos surrounding
our existence. This desire continues to this day as we search for a
theory that will finally unify and harmonise the forces of nature.
