"This is one of Robert A. Heinlein's most intriguing views of life in the next century - when interplanetary exploration and spacesuits are as commonplace as Sunday driving and overcoats are today. You'll enjoy this vastly entertaining picture of life in the space frontiers of the future." -New York Herald Tribune, ca. 1955.
