Applied Nonsingular Astrodynamics
This essential book is the first comprehensive exposition in the area of optimal low-thrust orbit transfer using non-singular variables.
Introduction to Orbital Perturbations
This textbook provides details of the derivation of Lagrange's planetary equations and of the closely related Gauss's variational equations, thereby covering a sorely needed topic in existing literature. Analytical solutions can help verify the results of numerical work, giving one confidence that his or her analysis is correct. The authors—all experienced experts in astrodynamics and space missions—take on the massive derivation problem step by step in order to help readers identify and understand possible analytical solutions in their own endeavors. The stages are elementary yet rigorous; suggested student research project topics are provided. After deriving the variational equations, ...
Orbital Relative Motion and Terminal Rendezvous
This book provides a comprehensive analysis of time-fixed terminal rendezvous around the Earth using chemical propulsion. The book has two main objectives. The first is to derive the mathematics of relative motion in near-circular orbit when subjected to perturbations emanating from the oblateness of the Earth, third-body gravity, and atmospheric drag. The mathematics are suitable for quick trajectory prediction and the creation of computer codes and efficient software to solve impulsive maneuvers and fly rendezvous missions. The second objective of this book is to show how the relative motion theory is applied to the exact precision-integrated, long-duration, time-fixed terminal rendezvous problem around the oblate Earth for the general elliptic orbit case. The contents are both theoretical and applied, with long-lasting value for aerospace engineers, trajectory designers, professors of orbital mechanics, and students at the graduate level and above.
The French Right Between the Wars
During the interwar years France experienced severe political polarization. At the time many observers, particularly on the left, feared that the French right had embraced fascism, generating a fierce debate that has engaged scholars for decades, but has also obscured critical changes in French society and culture during the 1920s and 1930s. This collection of essays shifts the focus away from long-standing controversies in order to examine various elements of the French right, from writers to politicians, social workers to street fighters, in their broader social, cultural, and political contexts. It offers a wide-ranging reassessment of the structures, mentalities, and significance of various conservative and extremist organizations, deepening our understanding of French and European history in a troubled yet fascinating era.
