	Lunar Orbiter program - Wikipedia, the free encyclopedia
		The Lunar Orbiter program was a series of five unmanned Lunar orbiter missions launched by the United States in 1966 through 1967 with the purpose of mapping the lunar surface before the Apollo landings.
		Lunar Orbiter 4 photographed the entire nearside and 95 % of the farside, and Lunar Orbiter 5 completed the farside coverage and acquired medium (20 m) and high (2 m) resolution images of 36 pre-selected areas.
		The Lunar Orbiters were all eventually commanded to crash on the Moon before their attitude control gas ran out so they would not present navigational or communications hazards to later Apollo flights.

	Lunar Orbiter 3 - Wikipedia, the free encyclopedia
		The Lunar Orbiter 3 was a spacecraft launched by NASA in 1967, designed primarily to photograph areas of the lunar surface for confirmation of safe landing sites for the Surveyor and Apollo missions.
		The spacecraft was placed in a cislunar trajectory and injected into an elliptical near-equatorial lunar orbit on 8 February at 21:54 UT. The orbit was 210.2 km x 1801.9 km with an inclination of 20.9 degrees and a period of 3 hours 25 minutes.
		The spacecraft was used for tracking purposes until it impacted the lunar surface on command at 14.3 degrees N latitude, 97.7 degrees W longitude (selenographic coordinates) on October 9, 1967.

	Lunar Orbiter
		The Lunar Orbiters’ primary mission was to obtain topographic data in the lunar equatorial region between 43° E and 56° W to help in the selection of suitable landing sites for the unmanned Surveyor and manned Apollo missions.
		With this objective achieved by Lunar Orbiter 3, the remaining two flights were able to carry out further photography of lunar surface features for purely scientific purposes.
		Lunar Orbiter 4 photographed the entire nearside and 95% of the farside; Lunar Orbiter 5 completed the farside coverage and acquired medium (20 m) and high (2 m) resolution images of 36 pre-selected areas.

	Lunar Orbiter 3
		The Lunar Orbiter 3 spacecraft was designed primarily to photograph smooth areas of the lunar surface for selection and verification of safe landing sites for the Surveyor and Apollo missions.
		It was stabilized in a three-axis orientation by using the sun and the star Canopus as primary angular references.
		The principal purpose of the Lunar Orbiter radiation measuring systems was to monitor, in real time, particle fluxes that would damage processed film in case of major solar cosmic ray events.

	Bill Keel's Space Bits - Tracking Lunar Orbiter V
		As a counterpoint to telescopic observations of the Apollo lunar missions, it turns out that there were earlier observations of spacecraft in lunar orbit.
		Lunar Orbiter IV was put into a high orbit (typically 3350 km above the surface), virtually completing the mapping mission, so mission V was put into a substantially lower orbit for high-resolution images of selected areas.
		The Lunar Orbiters were themselves responsible for some remarkable spectacular photographs - the first view of Earth above the stark lunar surface (I-101H2), a low-angle view of Copernicus (66-H-1470 or II-162H3) that brought home the extent of relief on the Moon, and the overhead view of the Mare Orientale impact basin (IV-187M).

	The Case For Motion Blur (Site not responding. Last check: 2007-10-08)
		The foundation of the case for motion blur lies in the fact that the Lunar Orbiter camera had a problem with this, and the Lunar Orbiter 3 mission was one known example.
		But if the presence of motion blur in Lunar Orbiter 3 images is not enough to make one wary, the blurry, streaked and smeared appearance of the images presented should.
		Some would claim this is proof that the doubles are true features on the lunar surface, but this would ignore the likelihood that the larger crater would have a coarse texture on a scale large enough not to disappear when blurred.
