In Volume 4 you embark on a truly mind-expanding odyssey. You delve into the origins, evolution, and the eventual fate of the universe. You'll comprehend the structure of matter - why there is so much support for the Big Bang, and how it was discovered. It explains why we only see the Observable Universe and not the Greater Universe. You'll understand why we can see back to the beginning of time! This volume explores multiple dimensions, the possible geometries of space, and the profound effects of Relativity in layman's terms. You'll see the probability of multiple and parallel universes, as well as computer programmed virtual universes. The reason why chaos and order drive the evolution of everything in the universe is explained. The discovery of dark matter and dark energy is revealed. You'll discover the very strange implications of the speed of light - the photon paradox - how gravity curves space - and why, at the speed of light, time stops, and mass becomes infinite! Cosmology explores whether a god may have created the universe and the implications of that. Prepare to have your mind challenged and your perspectives transformed as you navigate this profound volume.

Facing future-oriented aerospace applications, large-scale space construction and on-orbit services have rapidly developed. In such emerging and increasingly complex spacecraft maneuvering and control tasks, more precise control accuracy and higher performance guarantees need to be fully considered due to the need for safe close rendezvous movements.This book is dedicated to solving the aerospace system¿s performance guaranteed and precise control challenges with the expected transient and strict steady-state constraints. It is designed so that the aerospace closed-loop system can theoretically meet the pre-defined or prescribed performance requirements with the simple parameter selection. Furthermore, the expected performance constraints or indicators of the aerospace system time-domain performance response, such as settling time, overshoot, steady-state error, and state amplitude, will be directly guaranteed in the control design. Moreover, this book systematically proposes a series of spacecraft performance guaranteed control algorithms based on the practical situation of the aerospace system. For individual spacecraft, control algorithms that consider practical problems such as control task requirements, settling time constraints, transient performance normalization, input command constraints, and optimization faced by the on-orbit spacecraft are proposed to achieve the precise control objectives of the system under constraints and various complex situations. For the pre-combination and post-combination control of multiple spacecraft, game algorithms based on performance guarantees are proposed and thoroughly discussed. For spacecraft formations, control algorithms that consider full-state constraints, nonlinear uncertainties, output feedback, and collision avoidance are proposed.This book provides the theoretical basis and simulation experience for scholars and engineers to develop high-performance, high-precision spacecraft control algorithms. Furthermore, it hopes that these will contribute to the development of the world¿s aerospace technology.

This book describes the technologies of wireless power beaming to the aerospace crafts, such as the drone, flying car, aircraft, spacecraft, and rocket. Using a highly directional electromagnetic wave beam, energy is remotely supplied to mobility that moves at high speed without waste, and it is efficiently converted into the driving force of mobility. This technology will be indispensable for the full electrification of mobility in the future.¿This book specializes in aerospace mobility, where weight and other constraints are strict, and was written by researchers in different disciplines such as rocket engineering, plasma engineering, laser engineering, and communications and control engineering. Beamed-mobility forms a new area of integrated engineering. The new combination of optics and mechanical engineering creates a world where mobility is free to supply the energy needed for propulsion, wherever and wherever it goes. It is expected to become the core technology of mobility, energy, infrastructure, and services of the future society that extends to outer space. This book will serve as a good reference for graduate students, researchers, and professional engineers in the field of aerospace, electrical, and mechanical engineering.

This book explains on what basis a nation can claim the status of space power, what are the criteria differentiating a space power from ¿lesser¿ space actors, and how their spacepower can be empirically measured and assessed. To this end, it sets forth a comprehensive multidisciplinary framework to enable a dynamic comparison of space actors and of the pathways that lead them in and out of the space powers¿ club. Drawing upon a critical review of the existing literature, it conceptualises spacepower as a form of state power based on the complex interplay between the two defining dimensions of stateness, namely the well-studied dimension of capacity and the often neglected yet exceedingly important dimension of autonomy. The book demonstrates that only actors possessing high levels of both autonomy and capacity qualify as space powers. Different levels of either capacity or autonomy produce other types of space actors, including skilled spacefarers, self-reliant spacefarers, primed spacefarers, and emerging space actors. This innovative conceptual framework is complemented by an in-depth comparative assessment that collects and processes a large amount of hard-to-find data on the most active global space actors and aggregates multiple indicators into a compound, non-hierarchical index of space power visualised in the form of a matrix.

NASA's Mars 2020 mission successfully landed the Perseverance rover in Jezero crater on February 18, 2021.This book provides the definitive pre-landing documentation of the Mars 2020 mission, its scientific payload elements, and its exploration area.The chapters in this volume include detailed descriptions of: The Perseverance mission, and its relationship to a possible Mars Sample Return campaign; The geology of the mission's exploration environment in Jezero crater; and The purpose, design and operation of all seven instruments aboard the rover (Mastcam-Z, SHERLOC, RIMFAX, Supercam, MOXIE, PIXL, and MEDA) as well as the engineering cameras and the Mars helicopter Ingenuity. NASA's ambitious Mars 2020 mission extends a long arc of Martian exploration by seeking evidence that life may once have existed on Mars, and by preparing a collection of samples for possible return to Earth by a future mission. Mars 2020 will also enable future exploration by characterizing modern weather conditions and by demonstrating new technologies.Previously published in Space Science Reviews in the Topical Collection "The Mars 2020 Mission"
