A fascinating book written in a style that an interested layman can understand. Despite having lived through, and been interested in, all the space exploration since Sputnik, I hadn't appreciated all that is involved.
Dr Rogers is to be congratulated for covering a complex topic in a straightforward way without recourse to too much and hard-to-understand science. Indeed I occasionally found the book prompted further questions in my mind which I then enjoyed researching.
The author also covered relevant astronomy topics which I found very useful. One day perhaps, humans will set foot on another planet in the solar system and some of the problems that such a mission would have to face are covered well.
Clearly the author has a passion for space and astronomy, as well as the ability to put things over in an essentially simply way.
