Solar Sails: A Novel Approach to Interplanetary Travel Giovanni Vulpetti, Les Johnson, and Gregory Matloff
Solar sail propulsion will make space exploration more affordable and offer access to destinations within (and beyond) the solar system that are currently beyond our reach. This book describes solar sails, how they work and what they will be used for in the exploration of space in an easily readable manner which does not necessitate any prior knowledge of physics or solar sailing. It discusses current plans for solar sails and also describes how advanced technology, such as nanotechnology, might enhance solar-sail performance. Much has been accomplished recently to make solar sail technology very close to becoming an engineering reality and it will soon be used by the world’s space agencies in the exploration of the solar system and beyond.

Living Off the Land in Space: Green Roads to the Cosmos by Gregory Matloff, Les Johnson, and C Bangs
Drawing parallels with the terrestrial pioneers who had to "live off the land" as they made their way across the face of the Earth, this book describes how space travelers will use the resources they encounter to sustain missions to the furthest reaches of the solar system and beyond. Many of the technologies and approaches discussed have little or no impact on the environment of space -- providing truly "green" roads to the cosmos!
