This book includes a selection of 30 reviewed and enhanced manuscripts published during the 15th SpaceOps Conference held in May 2018 in Marseille, France. The selection was driven by their quality and relevance to the space operations community. The papers represent a cross-section of three main subject areas: Mission Management – management tasks for designing, preparing and operating a particular mission Spacecraft Operations – preparation and implementation of all activities to operate a space vehicle (crewed and uncrewed) under all conditions Ground Operations – preparation, qualification, and operations of a mission dedicated ground segment and appropriate infrastructure including antennas, control centers, and communication means and interfaces This book promotes the SpaceOps Committee’s mission to foster the technical interchange on all aspects of space mission operations and ground data systems while promoting and maintaining an international community of space operations experts.

This book includes a selection of reviewed and enhanced contributions presented at the SpaceOps 2021, the 16th International Conference on Space Operations, held virtually in May 2021. The chapter selections were made based upon their relevance to the current space operations community. The contributions represent a cross-section of three main subject areas: Mission Management – management tasks for designing, preparing and operating a particular mission; Spacecraft Operations – preparation and implementation of all activities to operate a space vehicle (crewed and uncrewed) under all conditions; and Ground Operations – preparation, qualification, and operations of a mission dedicated ground segment and appropriate infrastructure including antennas, control centers, and communication means and interfaces. The book promotes the SpaceOps Committee’s mission to foster the technical interchange on all aspects of space mission operations and ground data systems while promoting and maintaining an international community of space operations experts.

More than 50 years after the Mariner 4 flyby on 15 July 1965, Mars still represents the next frontier of space explorations. Of particular focus nowadays is crewed missions to the red planet. Over three sections, this book explores missions to Mars, in situ operations, and human-rated missions. Chapters address elements of design and possible psychological effects related to human-rated missions. The information contained herein will allow for the development of safe and efficient exploration missions to Mars.

This book collects selected papers from the 8th Conference on Signal and Information Processing, Networking and Computers held in Ji’nan, Shandong, China on September 13-17, 2021. It focuses on the current works of information theory, communication system, computer science, aerospace technologies and big data and other related technologies. Readers from both academia and industry of this field can contribute and find their interests from the book.

Impacts by asteroids or comets on Earth may lead to natural disasters of catastrophic dimensions. This book addresses legal and policy aspects of ‘planetary defence’ activities by space agencies and other actors aiming at the prediction and mitigation of Near-Earth Objects (NEOs).

Lunar explorations have received increasing attention in recent years with tremendous application values, including using the Moon as a remote sensing platform for Earth observation. As an active sensor, the Synthetic Aperture Radar (SAR) can detect changes in the atmosphere, terrain, and ocean. Moon-based SAR, complementary to the spaceborne SAR systems, expands our capabilities of watching and understanding the Earth. This book explains the Moon-Earth observation geometry, generic parameters, image focusing, and outlook using the Moon-based SAR. Written as a SAR imaging of Earth on the lunar-based platform, it makes it an essential reference to those interested in planetary and Earth sciences. FEATURES Uses the Moon as a remote sensing platform for Earth observation Explains how to obtain a high spatial resolution with a short revisit time using the Moon-based SAR Covers the observation geometry, range and signal models, two-dimensional signal spectrum, and focusing algorithms for the Moon-based SAR Presents a detailed analysis of sources of phase errors in the Moon-based SAR signal Includes global case studies and introduces conceptual ideas for further research This book is intended for senior graduate students, professional researchers, and engineers studying and working in the fields of lunar exploration and remote sensing applications, especially when dealing with high-orbit SAR studies.

Experts critically examine the belief that other intelligent life exists in our galaxy.

This new study considers military space strategy within the context of the land and naval strategies of the past. Explaining why and how strategists note the similarities of space operations to those of the air and naval forces, this book shows why many such strategies unintentionally lead to overemphasizing the importance of space-based offensive weaponry and technology. Counter to most U.S. Air Force doctrines, the book argues that space-based weapons don’t imbue superiority. It examines why both air and naval strategic frameworks actually fail to adequately capture the scope of real-world issues regarding current space operations. Yet by expanding a naval strategic framework to include maritime activities—which includes the interaction of land and sea—the breadth of issues and concerns regarding space activities and operations can be fully encompassed. Commander John Klein, United States Navy, uses Sir Julian Corbett’s maritime strategy as a strategic springboard, while observing the salient lessons of other strategists—including Sun Tzu, Clausewitz, Jomini, and Mao Tse-tung—to show how a space strategy and associated principles of space warfare can be derived to predict concerns, develop ideas, and suggest policy not currently recognized. This book will be of great interest to all students and scholars of military and strategic studies and to those with an interest in space strategy in particular.

This SpringerBrief explores the technological, economic, physiological, and psychological comparisons between a journey to the Moon versus a journey to Mars, taking into consideration the national and international perspectives at play. The author spent over six years interviewing leading space experts from around the world to learn why lunar habitats and the creation of a permanent presence on the Moon are an essential next step to human exploration and settlement in space. Practical reasons related to energy, telecommunications and networking, robotic systems, medical and scientific research, material processing, and more show why it must be the Moon First and Mars Second. These findings and recommendations have been adopted by current NASA Administrator Jim Bridenstine, as well as the current U. S. president. The research in this text reflects the author's experiences working internally within NASA Headquarters, the FAA Commercial Spaceflight Office, as well as the International Space University. It is partially based on Reneau’s award-winning Harvard thesis in conjunction with her Master's in International Relations.
