Without the newly developed methods and designs to reach space with the Saturn payload, the Apollo program won't be a success. In order to lift the massive payload required to reach the moon, the Saturn V rocket required millions pound of thrust. The First stage comprised of five-engine cluster for the 7.5 million pounds of thrust using liquid oxygen and kerosene fuel. The Second stage had five J-2 engines and the third with one J-2 engine all using hydrogen-oxygen fuel. Without the development of these powerful engines, the Saturn V rocket would not have lifted off the launch pad. Also, NASA developed a common bulkhead in the fuel cell to store two separate fuels with one single barrier to conserve space and minimize weight. Multi-staging
