This book considers global solutions to the restricted three-body problem from a geometric point of view. The authors seek dynamical channels in the phase space which wind around the planets and moons and naturally connect them. These low energy passageways could slash the amount of fuel spacecraft need to explore and develop our solar system. In order to effectively exploit these passageways, the book addresses the global transport. It goes beyond the traditional scope of libration point mission design, developing tools for the design of trajectories which take full advantage of natural three or more body dynamics, thereby saving precious fuel and gaining flexibility in mission planning. This is the key for the development of some NASA mission trajectories, such as low energy libration point orbit missions (e.g., the sample return Genesis Discovery Mission), low energy lunar missions and low energy tours of outer planet moon systems, such as a mission to tour and explore in detail the icy moons of Jupiter. This book can serve as a valuable resource for graduate students and advanced undergraduates in applied mathematics and aerospace engineering, as well as a manual for practitioners who work on libration point and deep space missions in industry and at government laboratories. the authors include a wealth of background material, but also bring the reader up to a portion of the research frontier.

"Equal Justice Under Law" is one of America's most proudly proclaimed and widely violated legal principles. But it comes nowhere close to describing the legal system in practice. Millions of Americans lack any access to justice, let alone equal access. Worse, the increasing centrality of law in American life and its growing complexity has made access to legal assistance critical for all citizens. Yet according to most estimates about four-fifths of the legal needs of the poor, and two- to three-fifths of the needs of middle-income individuals remain unmet. This book reveals the inequities of legal assistance in America, from the lack of access to educational services and health benefits to gross injustices in the criminal defense system. It proposes a specific agenda for change, offering tangible reforms for coordinating comprehensive systems for the delivery of legal services, maximizing individual's opportunities to represent themselves, and making effective legal services more affordable for all Americans who need them.

The aim of this book is to demonstrate to a wider audience, as well as to a more skilled audience, the many fascinating aspects of modern celestial mechanics. It sets out to do this without the use of mathematics. After giving the reader the technical tools needed for a basic understanding of the underlying physical phenomena (using only elementary mathematics), facts and figures are provided on historical events, modern discoveries and future applications. Contents are divided into major topics where the three "souls" of modern celestial mechanics (dynamical systems, Solar System and stellar systems, spaceflight dynamics) play a major role.
