Told in the first-person voice of wheeled robot that has been exploring Mars since 2012, an easy-to-follow account gives an overview of the science leading up to the creation of the rover, how the rover works, the launch into space for its 253-day journey to Mars, the tenuous landing, and a sampling of information that has been sent back to NASA in the past eight years. The large size of the picture book gives readers a sense of the enormity of the operation, of space, and of the barren landscape on the red planet. Mixed-media illustrations include details that will help young readers understand the mission, and they give Curiosity as much personality as a robot can have without detracting from the scientific information of the text.
