Rosetta isn't the first probe that's been sent to study comets, but it's the most successful as the first spacecraft to closely observe a comet as it approaches the sun. For 10 years, Rosetta moved around the solar system, just so it could finally meet up with the right comet and release a lander to further study it. Readers learn about Rosetta's incredible journey from just an idea to a fascinating robot with solar-charging batteries and other special features. From full-color diagrams of Rosetta to informative sidebars about the probe's findings, readers are sure to enjoy this book's STEM content.
