Lunar Orbiter 5

  1967-075A

---

The last Lunar Orbiter, spacecraft 3 or Lunar Orbiter E, was launched at 2233 on 1967 Aug 1 by Atlas Agena D from Cape Kennedy on azimuth 105.6 deg. Launch mass was 392 kg; mass prior to deorbit burn was 266 kg. The course correction was made at around 1100 on Aug 3. Lunar orbit insertion was at 1648 on Aug 5 into a 196 x 6040 km x 85.0 orbit, lowered on Aug 7 to 100 x 6050 km x 84.6 deg. Imaging was concluded at the end of August. After completion of the photo mission, the remaining Lunar Orbiters were used as tracking targets for the Apollo network. LO-5's orbit was tweaked on Oct 10 to help it survive an eclipse. The extended mission was ended when the nitrogen supply was exhausted. The spacecraft was deorbited on 1968 Jan 31 and impacted the lunar surface at 0758:10.
