This book carries out approximate estimates of the costs of implementing ISRU on the Moon and Mars. It is found that no ISRU process on the Moon has much merit. ISRU on Mars can save a great deal of mass, but there is a significant cost in prospecting for resources and validating ISRU concepts. Mars ISRU might have merit, but not enough data are available to be certain. In addition, this book provides a detailed review of various ISRU technologies. This includes three approaches for Mars ISRU based on processing only the atmosphere: solid oxide electrolysis, reverse water gas shift reaction...

A series of increasingly capable spacecraft were sent to explore the inner planets Venus and Mercury. The history of that planetary exploration is traced in this book along with the evolution of sophisticated spacecraft that unveiled long-sought secrets of the planets. The spacecraft were ingenious and reflected the best efforts of talented people working with the available technology of the day. Additionally, this book showcases engineering involved in those capable machines.
A consecutive series of 34 planetary spacecraft, which span the time period 1961 to 2021, are described. This...
