Although the Jet Propulsion Laboratory in Pasadena, California, has become synonymous with the United States’ planetary exploration during the past half century, its most recent focus has been on Mars. Beginning in the 1990s and continuing through the Mars Phoenix mission of 2007, JPL led the way in engineering an impressive, rapidly evolving succession of Mars orbiters and landers, including roving robotic vehicles whose successful deployment onto the Martian surface posed some of the most complicated technical problems in space flight history. In Exploration and Engineering, Erik M. Conway reveals how JPL engineers’ creative technological feats led to major breakthroughs in Mars exploration. He takes readers into the heart of the lab’s problem-solving approach and management structure, where talented scientists grappled with technical challenges while also coping, not always successfully, with funding shortfalls, unrealistic schedules, and managerial turmoil. Conway, JPL’s historian, offers an insider’s perspective into the changing goals of Mars exploration, the ways in which sophisticated computer simulations drove the design process, and the remarkable evolution of landing technologies over a thirty-year period. "A masterpiece of research and writing."—Quest: History of Spaceflight Quarterly "A 'must' for any reader of modern astronomy who wants insights into how the lab conducts its research, solves problems, and handle[s] technological challenges."—Midwest Book Review "A great tale of ambition, mishap and recovery, building on extensive archival research and interviews with JPL managers, scientists and engineers, to deliver a detailed overview of each mission's feats and failures . . . Exploration and Engineering is a great book for everyone seriously interested in the struggles and achievements of JPL as NASA's centre for Mars exploration."—Sky at Night Erik M. Conway is a historian of science and technology at the Jet Propulsion Laboratory, California Institute of Technology. He is the author of Atmospheric Science at NASA: A History.

A handsome and critical addition to the library of every historian, genealogist, and Civil War buff, this rare two-volume set is the official record of Minnesota's participation in the Civil and Dakota Wars. Published in two parts in the 1890s and written by the men who fought in battle, Minnesota in the Civil and Indian Wars contains regimental rosters (names lists with ages, muster dates, transfers, and remarks) as well as detailed narratives describing the wartime service of each regiment, battery, battalion, and brigade--their marches, campaigns, battles, surrenders, wounded lists, furloughs, reenlistments, and return to Minnesota. Letters, telegrams, and descriptions related to the development of the Dakota War, including dispatches written from the field, offer a personal face to this wartime history. Included for the first time is a 144-page index to all the regimental rosters, making this an invaluable research tool. Together, these volumes are the essential reference for Minnesota's troops and their campaigns.

Batteries 2: Research and Development in Non-Mechanical Electrical Power Sources provides information pertinent to the selection and operation of power source. This book focuses on the progress and further development in battery design. Organized into 38 chapters, this book begins with an overview of the metallurgical properties of a positive grid alloy as well as the properties of dispersion-strengthened lead. This text then explains the voltage maximum as being resistance polarization. Other chapters consider the standard heat of activation for the rate-determining step at the reversible potential and explain the difficulties of predicting the orbital performance of solar cells from terrestrial measurements. This book discusses as well the chemical changes occurring during the manufacture and life of lead–acid batteries. The final chapter deals with the mechanism of the processes that occur in fuel cells. This book is a valuable resource for chemical, electrical, telecommunications, electrochemical, and automotive engineers.
