Which probes were launched between 1966-1967 to provide high-quality photographs of the moon's entire surface?

The Lunar Orbiters were specifically designed to capture high-quality photographs of the Moon's entire surface during their missions in 1966 and 1967. These spacecraft played a pivotal role in mapping the Moon, providing detailed imagery that was crucial for future lunar exploration, including the Apollo missions. The photography taken by the Lunar Orbiters helped scientists understand the Moon's geology and surface features, which was essential for selecting landing sites and planning missions.

In contrast, while the Surveyors were also important for lunar exploration, their primary function was to land on the Moon and conduct experiments rather than provide extensive mapping images. The Earth Observatory System does not pertain to lunar missions, focusing instead on observing Earth. Similarly, the Solar Mesosphere Explorer was designed for solar observation rather than lunar exploration. Thus, the choice of the Lunar Orbiters is accurate as they directly contributed to obtaining comprehensive lunar photographic data during the specified timeline.
