I thought this book was brilliant in so many ways. It is smart and informative and even humorous at times. I will say that it is very technical and deals with a lot of science and engineering, so it may not be for people who do not have much knowledge into space exploration. I loved the insight it gave me and how it brought up things that occur when building space vehicles and rovers that I never would have thought of before. I also liked how the authors writes in a way that is not condescending, or like he thinks h is smarter than you. He wrote in a very down-to-earth manner while giving a lot of information and really teaching you about things. This book talks about the past, present, and future of space exploration and it is a fascinating read for those looking to learn more about what the space program accomplished with the Mars rover and what it hopes to accomplish in the years to come.
