This book, the first of a two-volume set, focuses on the basic
physical principles of blackbody radiometry and describes
artificial sources of blackbody radiation, widely used as sources
of optical radiation, whose energy characteristics can be
calculated on the base of fundamental physical laws. Following a
review of radiometric quantities, radiation laws, and radiative
heat transfer, it introduces the basic principles of blackbody
radiators design, details of their practical implementation, and
methods of measuring their defining characteristics, as well as
metrological aspects of blackbody-based measurements. Chapters are
dedicated to the effective emissivity concept, methods of
increasing effective emissivities, their measurement and modeling
using the Monte Carlo method, techniques of blackbody radiators
heating, cooling, isothermalization, and measuring their
temperature. An extensive and comprehensive reference source, this
book is of considerable value to students, researchers, and
engineers involved in any aspect of blackbody radiometry.
The Lunar Reconnaissance Orbiter (LRO) was successfully launched on
June 18, 2009 and joined an international eet of satellites
(Japan's SELENE/Kaguya, China's Chang'E, and India's Chandrayaan-1)
that have recently orbited the Moon for scienti c exploration p-
poses. LRO is the rst step to ful ll the US national space goal to
return humans to the Moon's surface, which is a primary objective
of NASA's Exploration Systems Mission - rectorate (ESMD).
TheinitialLROmissionphasehasaone-yeardurationfullyfundedunder ESMD
support. LRO is expected to have an extended phase of operations
for at least two additional years to undertake further lunar
science measurements that are directly linked to objectives
outlined in the National Academy of Science's report on the Scienti
c Context for Exploration of the Moon (SCEM). All data from LRO
will be deposited in the Planetary Data System (PDS) archive so as
to be usable for both exploration and science by the widest
possible community. A NASA Announcement of Opportunity (AO)
solicited proposals for LRO instruments with associated exploration
measurement investigations. A rigorous evaluation process - volving
scienti c peer review, in combination with technical, cost and
management risk assessments, recommended six instruments for LRO
development and deployment. The competitively selected instruments
are: Cosmic Ray Telescope for the Effects of Rad- tion (CRaTER),
Diviner Lunar Radiometer Experiment (DLRE), Lyman-Alpha Mapping
Project (LAMP), Lunar Exploration Neutron Detector (LEND), Lunar
Orbiter Laser - timeter (LOLA), and Lunar Reconnaissance Orbiter
Camera (LROC).

This book gathers selected and expanded contributions presented at
the 5th Symposium on Space Optical Instruments and Applications,
which was held in Beijing, China, on September 5-7, 2018. This
conference series is organized by the Sino-Holland Space Optical
Instruments Laboratory, a cooperative platform between China and
the Netherlands. The symposium focused on key technological
problems regarding optical instruments and their applications in a
space context. It covered the latest developments, experiments and
results on the theory, instrumentation and applications of space
optics. The book is split into five main sections: The first covers
optical remote sensing system design, the second focuses on
advanced optical system design, and the third addresses remote
sensor calibration and measurement. Remote sensing data processing
and information extraction are then presented, followed by a final
section on remote sensing data applications.
It has been known for a long time that stars are similar to our
Sun. But it was only in 1810 that they were shown to be made of an
incandescent gas. The chemical composition of this gas began to be
determined in 1860. In 1940, it was demonstrated that the energy
radiated by the stars is of thermonuclear origin. How stars form
from interstellar matter and how they evolve and die was understood
only recently, with our knowledge still incomplete. It was also
realized recently that close double stars present a wide variety of
extraordinary phenomena, which are far from being completely
explored.This book explains all these aspects, and also discusses
how the evolution of stars determine that of galaxies. The most
interesting observations are illustrated by spectacular images,
while the theory is explained as simply as possible, without
however avoiding some mathematical or physical developments when
they are necessary for a good understanding of what happens in
stars. Without being a textbook for specialists, this book can be
profitably read by students or amateurs possessing some basic
scientific knowledge, who would like to be initiated in-depth to
the fascinating world of stars.The author, an emeritus astronomer
of the Paris Observatory, worked in various domains of astronomy
connected with the subject of this book: interstellar matter and
evolution of stars and galaxies. He directed the Marseilles
observatory from 1983 to 1988 and served for fifteen years as Chief
Editor of the professional European journal Astronomy &
Astrophysics. He has written many articles and books about physics
and astronomy at different levels.
In 1942, the logician Kurt Godel and Albert Einstein became close
friends; they walked to and from their offices every day,
exchanging ideas about science, philosophy, politics, and the lost
world of German science. By 1949, Godel had produced a remarkable
proof: "In any universe described by the Theory of Relativity, time
cannot exist," Einstein endorsed this result reluctantly but he
could find no way to refute it, since then, neither has anyone
else. Yet cosmologists and philosophers alike have proceeded as if
this discovery was never made. In "A World Without Time," Palle
Yourgrau sets out to restore Godel to his rightful place in
history, telling the story of two magnificent minds put on the
shelf by the scientific fashions of their day, and attempts to
rescue the brilliant work they did together.
Astrobiology not only investigates how early life took hold of our
planet but also life on other planets - both in our Solar System
and beyond - and their potential for habitability. The book take
readers from the scars on planetary surfaces made by space rocks to
the history of the Solar System narrated by those space rocks as
well as exoplanets in other planetary systems. But the true
question is how life arose here or elsewhere. Modern comparative
genomics has revealed that Darwin was correct; a set of highly
conserved genes and cellular functions indicate that all life is
related by common ancestry. The Last Universal Common Ancestor or
LUCA sits at the base of the Tree of Life. However, once that life
took hold, it started to diversify and form complex microbial
communities that are known as microbial mats and stromatolites. Due
to their long evolutionary history and abundance on modern Earth,
research on the biological, chemical and geological processes of
stromatolite formation has provided important insights into the
field of astrobiology. Many of these microbialite-containing
ecosystems have been used as models for astrobiology, and NASA
mission analogs including Shark Bay, Pavilion and Kelly Lakes.
Modern microbialites represent natural laboratories to study
primordial ecosystems and provide proxies for how life could evolve
on other planets. However, few viral metagenomic studies (i.e.,
viromes) have been conducted in microbialites, which are not only
an important part of the community but also mirror its
biodiversity. This book focuses on particularly interesting sites
such as Andean lake microbialites, a proxy of early life since they
are characterized by very high UV light, while Alchichica and
Bacalar lakes are characterized by high-salt and oligotrophic
waters that nurture stromatolites. However, it is only the oasis of
Cuatro Cienegas Basin in Mexico that stored past life in its marine
sediments of the Sierra de San Marcos. This particular Sierra has a
magmatic pouch that moves the deep aquifer to the surface in a
cycle of sun drenched life and back to the depths of the magmatic
life in an ancient cycle that now is broken by the overexploitation
of the surface water as well as the deep aquifer in order to
irrigate alfalfa in the desert. The anthropocene, the era of human
folly, is killing this unique time machine and with it the memory
of the planet.
This well-documented and fascinating book tells how, over the
centuries, a series of visionaries, scientists, technologists, and
politicians fostered the involvement of Italy in space exploration.
The lives of these pioneers was often far from easy, yet they
persevered. The fruits of their efforts can today be witnessed in
Italy's success within the cutting-edge space sector. Italy's
history in space started at the end of the fourteenth century and
continued with the development of fireworks. Later, the nineteenth
century marked the beginning of research into rockets in a more
scientific way. After World War II, rocket technology was advanced
with the aid of German scientists, and in the 1960s Luigi Broglio,
the father of Italian space exploration, designed the San Marco
satellite. In 1979 the first Italian Space Plan was launched, but
it was the foundation of the Italian Space Agency in 1988 that
kick-started a program of exploration in various fields of cosmic
research. The outcome was construction of the Vega launcher and
collaboration in the International Space Station. Now the Italian
space industry stands ready to play an important role in the
Gateway orbital station. All of this history, and more, is explored
in this riveting book.
The book summarizes the results of the experimental studies of
phase relations in the chemical systems relevant to Earth, carried
out by the author in a time period of over 20 years between 1979
and 2001. It is based on 1000 piston-cylinder experiments at
pressures up to 4 GPa, and close to 700 experiments carried out
with a multi-anvil apparatus at pressures up to 24 GPA. This is the
largest published collection of calculated phase diagrams for the
chemical systems relevant to Earth. This is also the first time
that the phase relations at the relatively low pressures of the
lithospheric mantle, mainly applicable to the experimental
thermobarometry of metamorphic rocks and mantle xenoliths, are
seamlessly integrated with the phase relations of the
sublithospheric upper mantle and the uppermost lower mantle,
primarily applicable to inclusions in diamond and schocked
meteorites. "Tibor Gasparik has devoted his career to determining
the high-pressure, high-temperature phase relations of the
geologically important Sodium-Calcium-Magnesium-Aluminium-Silicon
(NCMAS) oxide system. This book is his opus magnum, summarizing
more than 1700 experiments in over 120 figures. ... I have found
Phase Diagrams for Geoscientists to be a useful first port-of-call
for finding the P-T stability fields ... and I can recommend the
book as a reference for geoscientists requiring an overview of the
stable phase assemblages in the top 700 km of the Earth." (David
Dobson, Geological Magazine, Vol. 142 (2), 2005)
High-resolution X-ray spectroscopy has become a powerful tool for
astrophysics since the launch of Chandra and XMM-Newton, ten years
ago. The grating spectrometers on both instruments still continue
to provide excellent data, while imaging calorimeters are being
prepared for future missions like Astro-H and IXO. The synergy with
other wavelength bands like the UV has been boosted by the addition
of COS to HST. X-ray spectroscopy offers unique diagnostics to
study almost any object in the Universe. This book contains review
papers on highlights and the state-of-the-art of X-ray spectroscopy
for a broad range of objects and on the prospects for future
studies.
This up-to-date and concise account of a critical period of the
early universe directly links the latest theories and experiments.
Targeted at cosmological problems rather than specific methods, it
begins with an introduction reviewing the early universe and looks
at why reionization is important. The process of reionization
analyzes simple analytical considerations and compares existing
observations, while a further chapter describes some of the issues
regarding the transition from Population III to Population II
stars, as well as the constraints that can be derived from WMAP.
Further chapters survey the latest numerical modeling and future
perspectives for studying the dark ages using galaxies as
probes.
Written by a scientist with much experience in both research and
writing, this account is equally suitable for young researchers as
well as master and PhD students.
Our Universe is amazing. This is its story, told in simple
language. The story tells how the Universe came to be what it is
today. It starts with the Big Bang and describes how stars, black
holes, and our solar system developed. It explores the evolution of
life on Earth and investigates the possibility of extra-terrestrial
life. It peers into the future and wonders about the Universe's
likely old age and death, or whatever else may be its end. The
challenge the book takes up is to explain all of this, including
some of the astonishing concepts we have in science, such as
Einstein's theories of Relativity and Quantum Mechanics, using
virtually no mathematics and without dumbing-down. All are
described narratively and explained using examples and anecdotes.
The book is written for young people with a thirst for learning
about the science of space, as well as for 'grown-ups' who want a
better understanding of this fascinating subject.
The author has the distinction of being the only wife of a European
astronaut who has also worked in the area of human spaceflight. Her
story is told from a unique perspective. Lena De Winne provides a
first-hand account of the ins and outs of the complex astronaut
spaceflight system. This book captures the individual stories of
crewmembers Roman Romanenko, Bob Thirsk, Frank De Winne and their
spouses Julia, Brenda and Lena, as they prepare and embark on a
unique spaceflight mission. Delivered with raw emotional intensity,
it reads like a novel, sharing the aspirations, anguish, surprises
and disappointments of its subjects. Yet it is resolutely
biographical, offering a vivid recollection of events as they
happened. An easy but precise overview of space science and
technology is also provided. Readers will not only become
familiarised with the human space flight program, they will also be
left with an exhilarating sense of having been a part of the
adventure. The book is suffused with an intimacy and honesty that
renders the lives of the crew and their spouses in an unprecedented
light.

A selection of the History, Scientific American, and Quality
Paperback Book Clubs For a very brief moment during the 1960s,
America was moonstruck. Boys dreamt of being an astronaut; girls
dreamed of marrying one. Americans drank Tang, bought "space pens"
that wrote upside down, wore clothes made of space age Mylar, and
took imaginary rockets to the moon from theme parks scattered
around the country. But despite the best efforts of a generation of
scientists, the almost foolhardy heroics of the astronauts, and 35
billion dollars, the moon turned out to be a place of "magnificent
desolation," to use Buzz Aldrin's words: a sterile rock of no
purpose to anyone. In Dark Side of the Moon, Gerard J. DeGroot
reveals how NASA cashed in on the Americans' thirst for heroes in
an age of discontent and became obsessed with putting men in space.
The moon mission was sold as a race which America could not afford
to lose. Landing on the moon, it was argued, would be good for the
economy, for politics, and for the soul. It could even win the Cold
War. The great tragedy is that so much effort and expense was
devoted to a small step that did virtually nothing for mankind.
Drawing on meticulous archival research, DeGroot cuts through the
myths constructed by the Eisenhower, Kennedy, and Johnson
administrations and sustained by NASA ever since. He finds a gang
of cynics, demagogues, scheming politicians, and corporations who
amassed enormous power and profits by exploiting the fear of what
the Russians might do in space. Exposing the truth behind one of
the most revered fictions of American history, Dark Side of the
Moon explains why the American space program has been caught in a
state of purposeless wandering ever since Neil Armstrong descended
from Apollo 11 and stepped onto the moon. The effort devoted to the
space program was indeed magnificent and its cultural impact was
profound, but the purpose of the program was as desolate and dry as
lunar dust.
Offers an accessible text and reference (a cosmic-ray manual) for
graduate students entering the field and high-energy
astrophysicists will find this an accessible cosmic-ray manual Easy
to read for the general astronomer, the first part describes the
standard model of cosmic rays based on our understanding of modern
particle physics. Presents the acceleration scenario in some detail
in supernovae explosions as well as in the passage of cosmic rays
through the Galaxy. Compares experimental data in the atmosphere as
well as underground are compared with theoretical models
Until now, important research on the historical records of comets
and meteor showers from China, Japan, and Korea has remained the
exclusive preserve of those with expertise in the relevant
languages. With a compilation like the present volume the authors
hope to ameliorate that situation. Applying the same rigorous
selection criteria and style of presentation as in the previous
catalogue, assembled and translated here are some 1,500 additional
observations of comets and meteor showers from China, Japan, and
Korea spanning nearly three millennia. With the publication of this
volume, most of the important historical records of East Asian
astronomical observations are now accessible in English. The
introductions and appendices provide all the required information
on specialized terminology, recording conventions, and nomenclature
the reader will need to make use of the records. In addition to
being an invaluable resource for professional astronomers, East
Asian astronomical records have materially aided the research of
scholars in fields as diverse as mythology, medieval iconography,
ancient chronology, and the oral history of pre-literate societies.
The book should be of great interest to cultural astronomers, as
well as to those engaged in historical and comparative research.
This book provides a systematic introduction to the observation and
application of kinetic Alfven waves (KAWs) in various plasma
environments, with a special focus on the solar-terrestrial
coupling system. Alfven waves are low-frequency and long-wavelength
fluctuations that pervade laboratory, space and cosmic plasmas.
KAWs are dispersive Alfven waves with a short wavelength comparable
to particle kinematic scales and hence can play important roles in
the energization and transport of plasma particles, the formation
of fine magneto-plasma structures, and the dissipation of turbulent
Alfven waves. Since the 1990s, experimental studies on KAWs in
laboratory and space plasmas have significantly advanced our
understanding of KAWs, making them an increasingly interesting
subject. Without a doubt, the solar-terrestrial coupling system
provides us with a unique natural laboratory for the comprehensive
study of KAWs. This book presents extensive observations of KAWs in
solar and heliospheric plasmas, as well as numerous applications of
KAWs in the solar-terrestrial coupling system, including solar
atmosphere heating, solarwind turbulence, solar wind-magnetosphere
interactions, and magnetosphere-ionosphere coupling. In addition,
for the sake of consistency, the book includes the basic theories
and physical properties of KAWs, as well as their experimental
demonstrations in laboratory plasmas. In closing, it discusses
possible applications of KAWs to other astrophysical plasmas.
Accordingly, the book covers all the major aspects of KAWs in a
coherent manner that will appeal to advanced graduate students and
researchers whose work involves laboratory, space and astrophysical
plasmas.
