High-Velocity Impact Phenomena covers a wide range of pertinent topics dealing with impact phenomena. The book discusses hypervelocity accelerators; stress wave propagation in solids; and the theory of impact. The text also describes the application of the theory of impact on thin targets and shields and correlation with experiment; the numerical evaluation of hypervelocity impact phenomena; and analytical studies of impact-generated shock propagation. The equation of state of solids from shock wave studies; metallurgical observations and energy partitioning; and engineering considerations in hypervelocity impact are also encompassed. Design engineers will find the book invaluable.

This is the story of the work of the original NASA space pioneers; men and women who were suddenly organized in 1958 from the then National Advisory Committee on Aeronautics (NACA) into the Space Task Group. A relatively small group, they developed the initial mission concept plans and procedures for the U. S. space program. Then they boldly built hardware and facilities to accomplish those missions. The group existed only three years before they were transferred to the Manned Spacecraft Center in Houston, Texas, in 1962, but their organization left a large mark on what would follow.Von Ehrenfried's personal experience with the STG at Langley uniquely positions him to describe the way the group was structured and how it reacted to the new demands of a post-Sputnik era. He artfully analyzes how the growing space program was managed and what techniques enabled it to develop so quickly from an operations perspective. The result is a fascinating window into history, amply backed up by first person documentation and interviews.
