With a title like this, I was sure I would love this book. The concepts inside are nicely written and explained fairly well. I really appreciate some of the space history given in this book; however, they do give incorrect information on Laika and Sputnik 2. My overall enjoyment was hampered by the silly and sometimes garish illustrations sprinkled throughout the book. It seems like they were aiming at a teen/tween audience with this book. This would probably be a great choice for teens/tweens, but there are better choices for adult readers. ( )
