Rocket Ship Galileo, a juvenile science-fiction novel by the American writer Robert A. Heinlein, published in 1947, features three teenagers who participate in a pioneering flight to the Moon. It was the first in the Heinlein juveniles, a long and successful series of science-fiction novels published by Scribner's. Heinlein originally envisioned the novel as the first of a series of books called "Young Rocket Engineers". Publishers initially rejected the script, judging going to the Moon as "too far out".

Robert Anson Heinlein was an American science fiction author, aeronautical engineer, and naval officer. Sometimes called the "dean of science fiction writers", he was among the first to emphasize scientific accuracy in his fiction, and was thus a pioneer of the subgenre of hard science fiction. His published works, both fiction and non-fiction, express admiration for competence and emphasize the value of critical thinking. His plots often posed provocative situations which challenged conventional social mores. His work continues to have an influence on the science-fiction genre, and on modern culture more generally.
