Apollo 9 was the third crewed mission in the United States Apollo space program, the second to be sent into orbit by a Saturn V rocket, and the first flight of the command and service module (CSM) with the Apollo Lunar Module. The crew spent ten days in low Earth orbit testing several aspects critical to landing on the Moon. - Wikipedia
