Two hours thirty-five minutes into the mission, the third stage engine was reignited for a 350-second burn to send the crew on the way to the moon.

Three hours into the mission, the crew separated the Command Serivce Module (nicknamed Odyssey) from the third stage and docked with the Lunar Module (nicknamed Aquarius). After the Lunar Module was extracted from the third stage, Mission Control changed the third stage’s trajectory so that it would impact on the lunar surface. Previous third stages had been sent past the moon into solar orbit. The energy of the impact was detected by seismic instruments left by the Apollo 12 astronauts. Future Saturn V third stages were successfully impacted on the moon.
