I had never heard of Mike Massimino until I got this book on clearance at Booksamillion. I am glad I decided to pick this up, because it was a very inspiring read. It was really awesome to see a child grow up to realize his dreams of being in space. Massimino worked on some really well known projects, and learning more about the Hubble Telescope was really neat. I remember that being a really big deal when I was in school. I highly recommend this book for fellow space lovers.
