With allusions to David Bowie and interplanetary travel, Life on Mars imagines a soundtrack for the universe to accompany the discoveries, failures, and oddities of human existence. In these brilliant new poems, Tracy K. Smith envisions a sci-fi future sucked clean of any real dangers, contemplates the dark matter that keeps people both close and distant, and revisits the kitschy concepts like "love" and "illness" now relegated to the Museum of Obsolescence. These poems reveal the realities of life lived here, on the ground, where a daughter is imprisoned in the basement by her own father, where celebrities and pop stars walk among us, and where the poet herself loses her father, one of the engineers who worked on the Hubble Space Telescope. With this remarkable third collection, Smith establishes herself among the best poets of her generation.
