	Lunar Orbiter 1 - Wikipedia, the free encyclopedia
		The Lunar Orbiter 1 robotic (unmanned) spacecraft, part of the Lunar Orbiter Program, 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.
		Lunar Orbiter 1 took the first two remote images of earth from the distance of the Moon, August 23rd 1966.
		The spacecraft was tracked until it impacted the lunar surface on command at 7 degrees N latitude, 161 degrees E longitude (selenographic coordinates) on the Moon's far side on October 29, 1966 on its 577th orbit.

	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 to the Moon (1966 - 1967)
		Five Lunar Orbiter missions were launched 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 percent of the farside, and Lunar Orbiter 5 completed the farside coverage and acquired medium (20-meter or 660-foot) and high (2-meter or 6.6-foot) resolution images of 36 pre-selected areas.
		The Lunar Orbiters had an ingenious imaging system, which consisted of a dual-lens camera, a film processing unit, a readout scanner, and a film handling apparatus.

	Lunar Orbiter 1, 2, 3, 4, 5
		The Lunar Orbiter program consisted of 5 Lunar Orbiters which returned photography of 99% of the surface of the Moon (near and far side) with resolution down to 1 meter.
		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.
		The main bus of the Lunar Orbiter had the general shape of a truncated cone, 1.65 meters tall and 1.5 meters in diameter at the base.

	LRO (Lunar Reconnaissance Orbiter)
		Set for a 2008 launch, Lunar Reconnaissance Orbiter (LRO) is planned to orbit the moon for at least one year and gather detailed maps of the lunar surface, data on the moon’s radiation levels and an in-depth look at its polar regions for resources.
		LROC (Lunar Reconnaissance Orbiter Camera) will acquire targeted images of the lunar surface capable of resolving small-scale features that could be landing site hazards, as well as wide-angle images at multiple wavelengths of the lunar poles to document changing illumination conditions and potential resources.
		LEND (Lunar Exploration Neutron Detector) will map the flux of neutrons from the lunar surface to search for evidence of water ice and provide measurements of the space radiation environment which can be useful for future human exploration.

	Lunar Orbiter 2
		At an altitude of 46 kilometers (29 miles), which was approximately the perilune height, the HR system photographed a 4.15- by 16.6-kilometer (2.58- by 10.32-mile) area of the lunar surface which was centered on a 31.6- by 37.4-kilometer (19.64- by 23.2-mile) area photographed by the MR system.
		A detailed description of the experiment, a bibliography, and indexes of all the available Lunar Orbiter 1 through 5 photos are contained in the report 'Lunar Orbiter Photographic Data,' NSSDC 69-05, June 1969.
		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.

	The first lunar base
		The lunar slide lander is by far the easiest (and cheapest) to construct with regard to lunar facilities, requiring only a long flat runway.
		A detailed estimate given in [2, p.170] shows that the lunar maria contain over 600,000 tons of helium-3 and a further 500,000 tons in the highlands for a total estimate of 1,100,000 tons for the lunar surface [2, p.170].
		Lunar oxygen delivered to LEO will not be economically competitive with water/ice lifted from earth until it can be lifted off the moon without rockets.

	LUNAR ORBITER 2 PHOTO OF THE CENTURY (Site not responding. Last check: 2007-10-21)
		In 1966 the space-probe Orbiter 2 photographed Copernicus from a mere 28 miles above the Moon's surface.
		The crater, approximately 150 miles away, was shown obliquely, and the results was termed 'the Picture of the Century'; it was the most magnificent lunar view obtained up to that time, though of course we have since had far more detailed images from later space-craft, notably Clementine and Prospector.
