An enjoyable day-in-the-life story. Mallon uses the transmissions from and reporting on Scott Carpenter's troubled 1962 space flight as the backbone, deploying them as signposts within a day of interconnected lives, focusing on a space-obsessed boy and the people orbiting his family in New York. Sometimes, Mallon stretches the concept thin, introducing characters that only appear once and never intersect with the main story, and too many of the transitions from Carpenter's mission to everyday life are a bit obvious and clumsy, but the narrative strengthens in final section of the book, pulling enough threads to both build an undefinable tension and depict the endless ricochet of full lives intersecting only briefly.
