This book highlights stories of the most important 13 ground-based observatories and 14 space probes in human history, leading readers through each significant step of human's astronomical observation journey. From the earliest Hooker Telescope and the Mount Wilson Observatory, to the latest FAST, JWST and DAMPE, the targets of observation range from large systems such as the solar system, the milky way, and the universe, to individual planets such as Jupiter, Saturn, Mars, and the remote stars, and to the matters that reveal the origin of the universe, such as dark matter and cosmic background radiation. The book presents the mysteries of the sky in an easily readable manner suitable for audiences of all ages who are curious about the universe and thirsty to know all the important discoveries in the past century, especially the last decade. With carefully-selected contents, the book weaves together a series of tales to make the convoluted history of astronomical observation full offun and excitement, ensuring that readers never lose interest during reading.

This book features state-of-the-art studies on the responsible innovation management. It illustrates the innovative methods from socio-economic and sustainable development dimensions and specifically mentions digitalisation's dark side, technology application challenges and enterprises management issues. The selected works contain enormous new case studies exploring ways to improve the development of related industries from responsible innovation perspectives. It covers about the multidisciplinary areas, and hence, it fosters close collaboration between researchers in diverse fields such as social science, economics and engineering. Researchers, corporate executives and engineers in these areas can benefit from the book.

This book presents the dynamic modeling and attitude control of flexible spacecraft with time-varying parameters. The dynamic characteristics, vibration control methods and attitude stabilization methods for spacecraft are systematically studied in respects of the theoretical modeling, numerical simulation and the ground experiment.Three active control theories in complex mode space are presented for flexible space structures. Optimal slew strategies based on variable amplitudes input shaping methods and coupling control methods are proposed for stabilization of flexible spacecraft. The research provides an important way to solve the problem of high-precision attitude control of flexible spacecraft with time-varying parameters. This book is appropriate for the researchers who focus on the multi-body dynamics, attitude and vibration control of flexible spacecraft.
