Mars Orbiters is about trying to uncover data from Mars to see what is on Mars and trying to see why the water disappeared from Mars. This story of how NASA,Russia and others are making improvements to their orbiters. The book should be in a school or a public library because people may want to check out it too learn more about the orbiters, the scientists who built them (like NASA) and the history of the orbiters. The table of contents was helpful,the timeline,glossary and index in the back of the book were really helpful. This book is best for grades 5th to 8th grade for people who want to know more about the the planets.
