This book makes a wonderful new edition to any spaceflight enthusiast library. The authors Jenkins and Frank, like their previous treatments have provided a nice compact book on the most recent and last servicing mission to the space telescope. The pictures in this work are outstanding. The opening sections of the book detailing the history and developement of the HST is informative and great reading. As I stated in a prior review, I wish the authors could chronicle the remaining space shuttle flights. They do a very good job of capturing the subject matter both in easy on the eyes text and did I mention outstanding pictures. I guess one could argue that this material is available on the net. But I for one still like books, and this format which not only covers the very last mission but also the other servicing missions to the telescope, is a handy guide to truly one of the greatest achievements in engineering and manned spaceflight.
