PreS-Gr 2--Newly independent readers will gain an understanding of Mars in this second entry to a Level 1 series on the universe. Bauer begins by asking children to imagine their own journey to the red planet. The trip would take at least six months! She further engages them with the kinds of facts that kids love: Mars is a planet that has two moons, blue sunsets, a canyon as wide as the entire United States, extreme dust storms, and ground that is potentially poisonous. Some kids may be able to read the additional content that follows the main text, while others may turn to an adult for support. A glossary with a pronunciation guide is included. Colorful, playful illustrations and simple text make this a pleasing introduction to outer space. VERDICT A beginning reader that is an excellent addition to any collection of STEM materials.--Gloria Koster, formerly at West Sch., New Canaan, CTCopyright 2021 School Library Journal, LLC Used with permission.
