Mons Blanc
Mont Blanc is a mountain in the Montes Alpes range on the Moon. It is located on the western edge of the range, near the shore of Mare Imbrium, at . Its width is about 25 kilometers; the height is 3.7–3.8 km above adjacent plains of Mare Imbrium and 1.12 km above lunar level of zero elevation (a sphere with radius 1737.4 km). The name of Mont Blanc, the highest mountain of terrestrial Alps, was proposed for this mountain by Johann Hieronymus Schröter. It was approved by International Astronomical Union in 1935. It is the only summit of Montes Alpes with proper name and the only extraterrestrial mountain, whose international name contains French word "Mont" instead of Latin "Mons".According tGazetteer of Planetary Nomenclatureas for 2015 Despite statements that lunar Mont Blanc, like terrestrial one, is a highest mountain of its Alps, measurements of Lunar Reconnaissance Orbiter The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently ...

Lunar Orbiter 4
Lunar Orbiter 4 was a robotic U.S. spacecraft, part of the Lunar Orbiter program, Lunar Orbiter Program, designed to orbit the Moon, after the three previous orbiters had completed the required needs for Project Apollo, Apollo mapping and site selection. It was given a more general objective, to "perform a broad systematic photographic survey of lunar surface features in order to increase the scientific knowledge of their nature, origin, and processes, and to serve as a basis for selecting sites for more detailed scientific study by subsequent orbital and landing missions". It was also equipped to collect selenodetic, radiation intensity, and micrometeoroid impact data. Mission Summary The spacecraft was placed in a Free-return trajectory, cislunar trajectory and injected into an elliptical near polar high lunar orbit for data acquisition. The orbit was with an inclination of 85.5 degrees and a period of 12 hours. After initial photography on May 11, 1967 problems started occu ...
