The Apollo spacecraft consisted of three parts: a command module, where the astronauts would travel; a service module, which contained supplies and equipment; and a lunar module, which would detach to land on the Moon. In all, a total of fifteen Apollo spacecraft were produced—three designed for unpiloted missions and twelve for piloted missions. The Apollo missions were launched using the Saturn V rocket, designed by Wernher von Braun and still the most powerful rockets ever successfully operated.
