Understand the fundamental basis of spaceflight with this cutting-edge guide As spacecraft engineering continues to advance, so too do the propulsion methods by which humans explore the solar system and will seek out the stars. Electric rocket propulsion has been the subject of considerable innovation and application in recent years, with thousands of electric thrusters now operating in space. For professionals in spacecraft engineering and closely related fields, this book provides critical knowledge that can alter the future of space flight. Fundamentals of Electric Propulsion offers a thorough grounding in electric propulsion for spacecraft, particularly the features and mechanisms underlying electrostatic and electromagnetic thrusters. Updated in the light of rapidly expanding knowledge, the second edition of this essential guide covers thruster principles, plasma physics, and more. It reflects the significant accomplishments by NASA’s Jet Propulsion Laboratory in this field, and promises to be a must-own volume for spacecraft engineering professionals. Readers of the second edition of Fundamentals of Electric Propulsion readers will also find: Extensive updates to chapters covering hollow cathodes and Hall thrusters, based on recent research results New chapters covering magnetic shielding in Hall thrusters, electromagnetic propulsion, future directions in research and development, and more Figures and homework problems in each chapter to facilitate learning and retention Fundamentals of Electric Propulsion is an essential work for spacecraft engineers and researchers working in spacecraft propulsion and related fields, as well as graduate students in electric propulsion, aerospace science, and space science courses.

Understand the power of dynamic arrays: a single formula can generate new and vastly more efficient spreadsheet possibilities. This book introduces spreadsheet users to dynamic array functions in Microsoft Excel 365, defines and details the distinctive ways in which they work, and shows how they can be applied to a wide swath of data-analytic tasks. While array formulas and functions have long held a place in the spreadsheet toolbox (although, for many of us, shunted to an obscure corner), the dynamic array engine offers a more user-friendly and intelligible set of means for manipulating spreadsheet data in the array mode. The single-formula, multi-cell capability of dynamic arrays has been extended to nearly all existing spreadsheet functions, offering a new, default way of working. As a result, many tasks can now be executed with dynamic arrays without having to resort to the new functions at all. After defining arrays and dynamic array formulas, this book helps you examine the dynamic array property of lifting and how it impacts the formulas, including those written with existing functions. Plenty of illustrations and formulas along the way help you get comfortable using them. From there, you will learn Excel 365's new dynamic functions, including the 14 currently in rollout, each accompanied by instructive examples. In many cases, the examples demonstrate how the new functions can work with long-available functions, such as MID, IF, COUNTIF, etc., which now also boast dynamic array functionality. What You Will Learn Unlock the dynamic array potential in Microsoft Excel Apply dynamic array functions and confidently direct them to real-world spreadsheet tasks Know the distinctive ways in which arrays work and can be applied to numerous data-analytic tasks Who This Book Is For Users of Excel 365 and beyond who are comfortable with, but not necessarily expert in, formula writing, as well as those who are unaware of or not fluent with dynamic arrays. It is also valuable to data journalists and other professionals in need of spreadsheet skills who may unaware of dynamic arrays, and the time they could save by applying them to their work.
