Lunar Orbiter I was launched at 1926 on 1966 Aug 10 by Atlas Agena D from Cape Kennedy. The Agena post-retro trajectory missed the moon by about 40000 km. On Aug 11 trouble struck when the Canopus sensor failed to acquire Canopus. The spacecraft attitude was calibrated by using the sensor to detect the Moon instead. Lunar Orbiter I made one mid course correction, at 0000 on Aug 12, and entered lunar orbit at around 1550 on 1966 Aug 14. The initial orbit was 191 x 1867 km x 12.2 deg. The periapsis was lowered on Aug 21 to 56 km, and on Aug 29 to 40 km. Lunar Orbiter I's mission was dedicated to surveying Apollo landing sites. The spacecraft was deorbited at 1225 on 1966 Oct 29 and impacted the surface an hour later.
