With contributions from leading scientists in the field, and edited by two of the most prominent astronomers of our time, this is a totally authoritative volume on X-ray astronomy that will be essential reading for everyone interested - from students to astrophysicists and physicists. All the aspects of this exciting area of study are covered, from astronomical instrumentation to extragalactic X-ray astronomy.
Rotation is ubiquitous at each step of stellar evolution, from star formation to the final stages, and it affects the course of evolution, the timescales and nucleosynthesis. Stellar rotation is also an essential prerequisite for the occurrence of Gamma-Ray Bursts. In this book the author thoroughly examines the basic mechanical and thermal effects of rotation, their influence on mass loss by stellar winds, the effects of differential rotation and its associated instabilities, the relation with magnetic fields and the evolution of the internal and surface rotation. Further, he discusses the numerous observational signatures of rotational effects obtained from spectroscopy and interferometric observations, as well as from chemical abundance determinations, helioseismology and asteroseismology, etc. On an introductory level, this book presents in a didactical way the basic concepts of stellar structure and evolution in "track 1" chapters. The other more specialized chapters form an advanced course on the graduate level and will further serve as a valuable reference work for professional astrophysicists.
This biography summarizes the seminal contributions to auroral and space science of Carl Stormer (1874 - 1957). He was the first to develop precise photographic methods to calculate heights and morphologies of diverse auroral forms during four solar cycles. Stormer independently devised numerical techniques to determine the trajectories of high-energy charged particles allowed and forbidden in the Earth's magnetic field. His theoretical analyses explained cosmic ray access to the upper atmosphere, 20 years before they were identified by other scientists. Stormer's crowning achievement, "The Polar Aurora," published when he was 81 years old, stands to this day as a regularly cited guide in graduate-level courses on space physics. The authors present the life of this prodigious scientist in relation to the cultural life of early 20th century in Norway and to the development of the space sciences in the post-Sputnik era.
This book provides a showcase for the incredibly well-preserved flight-textured tektites of southern Australia, which are the world's finest known examples. It provides an overview of their forms and flight features, which can be expected to appear, at least in part, on any objects falling from space. Some of these specimens are so perfectly shaped that it is hard to believe that they have been buried in the recent strata of Australia for 770,000 years. It also discusses the history of the story of their incredible flight into space and return becoming widely accepted, which led to them being recognized as space travelers. Further, it describes their classical shapes and offers an explanation of how each developed. It provides collectors, meteoriticists, and museum curators with insights into the astounding forms of Australian tektites produced by hypersonic flight.
In celebration of the 50th anniversary of the first man on the moon, this book for the first time ever looks at the artefacts left behind on the moon from the perspective of architecture. The book looks at every single mission - manned and unmanned - that has actually landed on the moon. It covers the time of the beginning of the Soviet and American space race with the landing of Luna 2 in 1959, to the present with China's Chang'e 3 moon rover. This architectural guide differentiates itself from other scientific and edu cational books through its abstract approach to the topic of architecture on the moon. The content does not feature science fiction, but rather the question of what exists and what implications these bizarre structures hold for the future of architecture on other planets - as these topics are quite pertinent in today's world of the commercialization of spaceflight, with SpaceX and NASA planning to take humans to Mars in the next 15 years. The guide brings together authors both from the East and the West. Contributors on the Russian side include Galina Balashova, the famous archi tect of the Soviet space program, and the expert Alexander Glushko, son of the deceased chief engineer of the Soviet space program, Valentin Glushko. Further contributions by Evangelos Kotsioris (MoMA), Brian Harvey (China), Gurbir Singh (India), and Olga Bannova (University of Houston).
This volume summarizes the recent results of the exploration of Venus, Mars and Titan in the field of space plasma physics. These are the only non-magnetic solar system bodies having dense atmospheres. A number of space missions investigated these objects; the past and the current missions are put in context with modern theoretical descriptions. The strength of the book is the comparison of the similarities and differences in the plasma interaction of Venus, Mars and Titan; such comparisons have not yet been published. This volume is aimed at graduate students and researchers working in planetary science and space physics. Previously published in Space Science Reviews journal, Vol. 162/1-4, 2011.
The Earth has limited material and energy resources. Further development of the humanity will require going beyond our planet for mining and use of extraterrestrial mineral resources and search of power sources. The exploitation of the natural resources of the Moon is a first natural step on this direction. Lunar materials may contribute to the betterment of conditions of people on Earth but they also may be used to establish permanent settlements on the Moon. This will allow developing new technologies, systems and flight operation techniques to continue space exploration. In fact, a new branch of human civilization could be established permanently on Moon in the next century. But, meantime, an inventory and proper social assessment of Moon's prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Moon with energy and other vital resources. The book collects together recent proposals and innovative options and solutions. It is a useful source of condensed information for specialists involved in current and impending Moon-related activities and a good starting point for young researchers.
This book makes good background reading for much of modern magnetospheric physics. Its origin was a Festspiel for Professor Jim Dungey, former professor in the Physics Department at Imperial College on the occasion of his 90th birthday, 30 January 2013. Remarkably, although he retired 30 years ago, his pioneering and, often, maverick work in the 50's through to the 70's on solar terrestrial physics is probably more widely appreciated today than when he retired. Dungey was a theoretical plasma physicist. The book covers how his reconnection model of the magnetosphere evolved to become the standard model of solar-terrestrial coupling. Dungey's open magnetosphere model now underpins a holistic picture explaining not only the magnetic and plasma structure of the magnetosphere, but also its dynamics which can be monitored in real time. The book also shows how modern day simulation of solar terrestrial coupling can reproduce the real time evolution of the solar terrestrial system in ways undreamt of in 1961 when Dungey's epoch-making paper was published. Further contributions on current Earth magnetosphere research and space plasma physics included in this book show how Dungey's basic ideas have remained explanative 50 years on. But the Festspiel also introduced some advances that possibly Dungey had not foreseen. One of the contributions presented in this book is on the variety of magnetospheres of the solar system which have been seen directly during the space age, discussing the variations in spatial scale and reconnection time scale and comparing them in respect of Earth, Mercury, the giant planets as well as Ganymede.
This book describes the basic physical principles of atomic spectroscopy and the absorption and emission of radiation in astrophysical and laboratory plasmas. It summarizes the basics of electromagnetism and thermodynamics and then describes in detail the theory of atomic spectra for complex atoms, with emphasis on astrophysical applications. Both equilibrium and non-equilibrium phenomena in plasmas are considered. The interaction between radiation and matter is described, together with various types of radiation (e.g., cyclotron, synchrotron, bremsstrahlung, Compton). The basic theory of polarization is explained, as is the theory of radiative transfer for astrophysical applications. Atomic Spectroscopy and Radiative Processes bridges the gap between basic books on atomic spectroscopy and the very specialized publications for the advanced researcher: it will provide under- and postgraduates with a clear in-depth description of theoretical aspects, supported by practical examples of applications.
The book describes the basic concepts of spaceflight operations, for both, human and unmanned missions. The basic subsystems of a space vehicle are explained in dedicated chapters, the relationship of spacecraft design and the very unique space environment are laid out. Flight dynamics are taught as well as ground segment requirements. Mission operations are divided into preparation including management aspects, execution and planning. Deep space missions and space robotic operations are included as special cases. The book is based on a course held at the German Space Operation Center (GSOC).
This book is an introduction to contemporary plasma physics that discusses the most relevant recent advances in the field and covers a careful choice of applications to various branches of astrophysics and space science. The purpose of the book is to allow the student to master the basic concepts of plasma physics and to bring him or her up to date in a number of relevant areas of current research. Topics covered include orbit theory, kinetic theory, fluid models, magnetohydrodynamics, MHD turbulence, instabilities, discontinuities, and magnetic reconnection. Some prior knowledge of classical physics is required, in particular fluid mechanics, statistical physics, and electrodynamics. The mathematical developments are self-contained and explicitly detailed in the text. A number of exercises are provided at the end of each chapter, together with suggestions and solutions.
The First Edition of The Sun from Space, completed in 1999, focused on the early accomplishments of three solar spacecraft, SOHO, Ulysses, and Yohkoh, primarily during a minimum in the Sun's 11-year cycle of magnetic activity. The comp- hensive Second Edition includes the main ndings of these three spacecraft over an entire activity cycle, including two minima and a maximum, and discusses the signi cant results of six more solar missions. Four of these, the Hinode, RHESSI, STEREO, and TRACE missions were launched after the First Edition was either nished or nearly so, and the other two, the ACE and Wind spacecraft, extend our investigations from the Sun to its varying input to the Earth. The Second Edition does not contain simple updates or cosmetic patch ups to the material in the First Edition. It instead contains the relevant discoveries of the past decade, integrated into chapters completely rewritten for the purpose. This provides a fresh perspective to the major topics of solar enquiry, written in an enjoyable, easily understood text accessible to all readers, from the interested layperson to the student or professional.
This thesis focuses on magnetic reconnection processes in the boundary layer of the interplanetary magnetic cloud. Magnetic reconnection is an important and frontier topic in the realm of physics. Various physical phenomena can be observed during the reconnection process but lots of them are not fully understood. This thesis provides the first observational evidence of energetic electrons associated with magnetic reconnection in the solar wind and discusses the particle acceleration problems. In addition, after analyzing the particle flux variations in Magnetic Cloud Boundary Layer, the thesis proposes a possible new criterion for the identification of magnetic reconnection in the solar wind. These tantalizing results could be particular clues to understand the dynamical problems in magnetic reconnection processes.
Based on extensive primary sources, many never previously translated into English, this is the definitive account of the origins of Ceres as it went from being classified as a new planet to reclassification as the first of a previously unknown group of celestial objects. Cunningham opens this critical moment of astronomical discovery to full modern analysis for the first time. This book includes all the voluminous correspondence, translated into English, between the astronomers of Europe about the startling discovery of Ceres by Piazzi in 1801. It covers the period up to March 1802, at which time Pallas was discovered. Also included are Piazzi's two monographs about Ceres, and the sections of two books dealing with Ceres, one by Johann Bode, the other by Johann Schroeter. The origin of the word 'asteroid' is explained, along with several chapters on the antecedents of the story going back to ancient Greek times. The formulation of Bode's Law is given, as are the details on the efforts of Baron von Zach to organize a search for the supposed missing planet between Mars and Jupiter. Examples of verse created to commemorate the great discovery are included in this first volume. The author, who has a PhD in the History of Astronomy, is a dedicated scholar of the story of asteroids and his research on the discovery of Ceres is comprehensive and fully sourced. The discovery came at a time when rival astronomers were in hot competition with each other, and when the true nature of these celestial bodies was not yet known. With astronomers in France, Italy and beyond vying to understand and receive credit for the new class of astral bodies, drama was not in short supply--nor were scientific advances.
This book is an up-to-date compendium on spacecraft attitude and orbit control (AOC) that offers a systematic and complete treatment of the subject with the aim of imparting the theoretical and practical knowledge that is required by designers, engineers, and researchers. After an introduction on the kinematics of the flexible and agile space vehicles, the modern architecture and functions of an AOC system are described and the main AOC modes reviewed with possible design solutions and examples. The dynamics of the flexible body in space are then considered using an original Lagrangian approach suitable for the control applications of large space flexible structures. Subsequent chapters address optimal control theory, attitude control methods, and orbit control applications, including the optimal orbital transfer with finite and infinite thrust. The theory is integrated with a description of current propulsion systems, with the focus especially on the new electric propulsion systems and state of the art sensors and actuators.
Includes the proceedings from the 7th IAASS Conference, "Space Safety is No Accident," held in Friedrichshafen, Germany, in October 2014. The 7th IAASS Conference, "Space Safety is No Accident" is an invitation to reflect and exchange information on a number of topics in space safety and sustainability of national and international interest. The conference is also a forum to promote mutual understanding, trust and the widest possible international cooperation in such matters. The once exclusive "club" of nations with autonomous sub-orbital and orbital space access capabilities is becoming crowded with fresh and ambitious new entrants. New commercial spaceports are starting operations and others are being built. In the manned spaceflight arena a commercial market is becoming a tangible reality with suborbital spaceflights and government use of commercial services for cargo and crew transportation to orbit. Besides the national ambitions in space, the international cooperation both civil and commercial is also gaining momentum. In the meantime robotic space exploration will accelerate and with it the need to internationally better regulate the usage of nuclear power sources. Space-bound systems and aviation traffic will share more and more a crowded airspace, while aviation will increasingly rely on space-based safety-critical services. Finally, most nations own nowadays space assets, mainly satellites of various kinds and purposes, which are under the constant threat of collision with other spacecraft and with the ever increasing number of space debris. Awareness is increasing internationally (as solemnly declared since decades in space treaties) that space is a mankind asset and that we all have the duty of caring for it. Without proactive and courageous international initiatives to organize space, we risk to negate access and use of space to future generations.
Short Historical Overview In the 1940s, two phenomena in the ?eld of cosmic rays (CR) forced scientists to think that the Sun is a powerful source of high-energy particles. One of these was discovered because of the daily solar variation of CR, which the maximum number of CR observed near noon (referring to the existence of continuous ?ux of CR from the direction of the Sun); this became the experimental basis of the theory that CR's originate from the Sun (or, for that matter, from within the solar system) (Alfven 1954). The second phenomenon was discovered when large ?uxes of high energy particles were detected from several solar ?ares, or solar CR. These are the - called ground level events (GLE), and were ?rst observed by ionization chambers shielded by 10 cm Pb (and detected mainly from the secondary muon-component CR that they caused) during the events of the 28th of February 1942, the 7th of March 1942, the 25th of July 1946, and the 19th of November 1949. The biggest such event was detected on the 23rd of February 1956 (see the detailed description in Chapters X and XI of Dorman, M1957). The ?rst phenomenon was investigated in detail in Dorman (M1957), by ?rst correcting experimental data on muon temperature effects and then by using coupling functions to determine the change in particle energy caused by the solar-diurnal CR variation.
Understanding the stars is the bedrock of modern astrophysics. Stars are the source of life. The chemical enrichment of our Milky Way and of the Universe withallelementsheavierthanlithiumoriginatesintheinteriorsofstars.Stars arethe tracersofthe dynamics ofthe Universe,gravitationallyimplying much more than meets the eye. Stars ionize the interstellar medium and re-ionized the early intergalactic medium. Understanding stellar structure and evolution is fundamental. While stellar structure and evolution are understood in general terms, we lack important physical ingredients, despite extensive research during recent decades.Classicalspectroscopy,photometry,astrometryandinterferometryof stars have traditionally been used as observational constraints to deduce the internal stellar physics. Unfortunately, these types of observations only allow the tuning of the basic common physics laws under stellar conditions with relatively poor precision. The situation is even more worrisome for unknown aspects of the physics and dynamics in stars. These are usually dealt with by using parameterised descriptions of, e.g., the treatments of convection, rotation,angularmomentumtransport,theequationofstate,atomicdi?usion andsettlingofelements,magneto-hydrodynamicalprocesses,andmore.There is a dearth of observational constraints on these processes, thus solar values areoftenassignedtothem.Yetitishardtoimaginethatonesetofparameters is appropriate for the vast range of stars.
Oceans were long thought to exist in all corners of the Solar System, from carbonated seas percolating beneath the clouds of Venus to features on the Moon's surface given names such as "the Bay of Rainbows" and the "Ocean of Storms." With the advent of modern telescopes and spacecraft exploration these ancient concepts of planetary seas have, for the most part, evaporated. But they have been replaced by the reality of something even more exotic. For example, although it is still uncertain whether Mars ever had actual oceans, it now seems that a web of waterways did indeed at one time spread across its surface. The "water" in many places in our Solar System is a poisoned brew mixed with ammonia or methane. Even that found on Jupiter's watery satellite Europa is believed similar to battery acid. Beyond the Galilean satellites may lie even more "alien oceans." Saturn's planet-sized moon Titan seems to be subject to methane or ethane rainfall. This creates methane pools that, in turn, become vast lakes and, perhaps, seasonal oceans. Titan has other seas in a sense, as large shifting areas of sand covering vast plains have been discovered. Mars also has these sand seas, and Venus may as well, along with oceans of frozen lava. Do super-chilled concoctions of ammonia, liquid nitrogen, and water percolate beneath the surfaces of Enceladus and Triton? For now we can only guess at the possibilities. 'Alien Seas' serves up part history, part current research, and part theory as it offers a rich buffet of "seas" on other worlds. It is organized by location and by the material of which various oceans consist, with guest authors penning specific chapters. Each chapter features new original art depicting alien seas, as well as the latest ground-based and spacecraft images. Original diagrams presents details of planetary oceans and related processes.
The Mars Science Laboratory is the latest and most advanced NASA roving vehicle to explore the surface of Mars. The Curiosity rover has landed in Gale crater and will explore this region assessing conditions on the surface that might be hospitable to life and paving the way for later even more sophisticated exploration of the surface. This book describes the mission, its exploration and scientific objectives, studies leading to the design of the mission and the instruments that accomplish the objectives of the mission. This book is aimed at all those engaged in Martian studies as well as those interested in the origin of life in other environments. It will be a valuable reference for anyone who uses data from the Mars Science Laboratory. Previously published in Space Science Reviews journal, Vol. 170/1-4, 2012.
Readers will find grouped together here the most recent observations, current theoretical models and present understanding of the coupled atmosphere, magnetosphere and solar wind system. The book begins with a general discussion of mass, energy and momentum transport in magnetodiscs. The physics of partially ionized plasmas of the giant planet magnetodiscs is of general interest throughout the field of space physics, heliophysics and astrophysical plasmas; therefore, understanding the basic physical processes associated with magnetodiscs has universal applications. The second chapter characterizes the solar wind interaction and auroral responses to solar wind driven dynamics. The third chapter describes the role of magnetic reconnection and the effects on plasma transport. Finally, the last chapter characterizes the spectral and spatial properties of auroral emissions, distinguishing between solar wind drivers and internal driving mechanisms. The in-depth reviews provide an excellent reference for future research in this discipline.
This book is the result of a working group sponsored by ISSI in Bern, which was initially created to study possible ways to calibrate a Far Ultraviolet (FUV) instrument after launch. In most cases, ultraviolet instruments are well calibrated on the ground, but unfortunately, optics and detectors in the FUV are very sensitive to contaminants and it is very challenging to prevent contamination before and during the test and launch sequences of a space mission. Therefore, ground calibrations need to be confirmed after launch and it is necessary to keep track of the temporal evolution of the sensitivity of the instrument during the mission. The studies presented here cover various fields of FUV spectroscopy, including a catalog of stellar spectra, datasets of Moon Irradiance, observations of comets and measurements of the interplanetary background. Detailed modelling of the interplanetary background is presented as well. This work also includes comparisons of older datasets with current ones. This raises the question of the consistency of the existing datasets. Previous experiments have been calibrated independently and comparison of the datasets may lead to inconsistencies. The authors have tried to check that possibility in the datasets and when relevant suggest a correction factor for the corresponding data.
"Inside NASA" explores how an agency praised for its planetary probes and expeditions to the moon became notorious for the explosion of the space shuttle "Challenger" and a series of other malfunctions. Using archival evidence as well as in-depth interviews with space agency officials, Howard McCurdy investigates the relationship between the performance of the American space program and NASA's organizational culture. He begins by identifying the beliefs, norms, and practices that guided NASA's early successes. Originally, the agency was dominated by the strong technical culture rooted in the research-and-development organizations from which NASA was formed. To launch the expeditions to the moon, McCurdy explains, this technical culture was linked to an organizational structure borrowed from the Air Force ballistic-missile program. Changes imposed to accomplish the lunar landing--along with the normal aging process and increased bureaucracy in the government as a whole--gradually eroded NASA's original culture and reduced its technical strength.
Beginning with the basic elements that differentiate space programs from other management challenges, Space Program Management explains through theory and example of real programs from around the world, the philosophical and technical tools needed to successfully manage large, technically complex space programs both in the government and commercial environment. Chapters address both systems and configuration management, the management of risk, estimation, measurement and control of both funding and the program schedule, and the structure of the aerospace industry worldwide.
Employing the same informational approach Erik Seedhouse used in "SpaceX" and "Bigelow Aerospace", this new book familiarizes space enthusiasts with the company XCOR Aerospace and examines the design of the two-seater Lynx. The new spaceplane's low weight and high octane fuel confer important advantages, such as direct runway launches and the ability to fly several times per day. Over the last 15 years, XCOR has developed and built 13 different rocket engines, built and flown two manned rocket-powered aircraft and has accumulated over 4,000 engine firings and nearly 500 minutes of run time on their engines. This book serves as a go-to reference guide for suborbital scientists and those seeking to learn how one company has found success. Additionally, it describes the medical and training requirements for those flying on board the Lynx and the related critical roles of the astronaut trainers and a new breed of commercial space pilots. The end result is a thorough chronicle of the development of rocket propulsion, avionics, simulator and ground support operations being put into play by XCOR with the Lynx. |
