This was a great “get to know space” guide. The information was kept brief, but reachable, fulfilling, and included many things most space books for this age do not. My only real problem with the book is no real pictures. Everything is illustrations. They are wacky and fun, but unlike other books in this series, real pictures are an advantage. When talking weights and measures, real pictures are not as important, as they are talking about comets and black holes.
