Donna Shirley's 35-year career as an aerospace engineer reached a jubilant pinnacle in July 1997 when Sojourner—the solar-powered, self-guided, microwave-oven-sized rover—was seen exploring the Martian landscape in Pathfinder's spectacular images from the surface of the red planet. The event marked a milestone in space, but for Donna Shirley, the leader of the mostly male team that designed and built Sojourner—and the first woman ever to manage a NASA program—it marked a triumph of another kind. is Shirley's captivating memoir of a life and career spent reaching for the stars. From her seemingly outlandish aspiration at age ten to build aircraft, to abandoning high school Home Ec in favor of mechanical drawing, and, at sixteen, becoming a licensed pilot, Shirley defied expectations from the beginning. In a vivid narrative, rich with anecdotes and thrilling turning points, Shirley recounts the intense battles she waged to defend her vision and the ingenuity and resourcefulness of her committed team. Her moment-by-cliffhanging-moment account of Pathfinder's landing and Sojourner's first tentative foray across the sands of Mars brilliantly captures the fulfillment of a lifelong dream as it heralds a brave new era of space exploration.
