Mike Massimino writes astronaut memoir with a strong emphasis on persistence, engineering and the practical realities of space missions. Spaceman traces his route from childhood fascination with space through repeated setbacks, NASA selection and two Space Shuttle missions servicing the Hubble Space Telescope. A central sequence describes an orbital repair complicated by a stripped screw and a handrail that had to be broken away, turning technical improvisation into one of the book's clearest examples of teamwork under pressure. Moonshot offers shorter lessons drawn from similar experiences for readers interested in resilience and problem-solving. Massimino's prose is warm, funny and accessible, making his work fit astronaut memoir, engineering stories and spaceflight non-fiction for general readers. Read more Less
