Rock Star: How Ursula Marvin Mapped Moon Rocks and Meteorites

Geologist Ursula Marvin (1921–2018) appears as an icon of determination in this extended account of the subject’s expedition to Antarctica. After touching on Marvin’s upbringing and the gender discrimination she experiences in college, comprehensive narration highlights early professional accomplishments before turning to her journey to the South Pole: “No woman had searched for meteorites at the bottom of the world. Ursula wanted to be the first.” Wallace next offers an avalanche of details, including the name of the figure’s snowmobile (Blue Ice) and the total of meteorites she locates in the first week (159). On the cusp of a find, Marvin breaks her leg, but passion keeps her spirits buoyed. Thick brushstrokes add texture to Carpenter’s minimalist scenes, which capture the physically trying aspects of the journey. Background characters are portrayed with various skin tones. Includes extensive back matter. Ages 4–8. (Oct.)
