Daubrée (crater)
Daubrée is a Lunar craters, lunar impact crater that is located to the southwest of the Mare Serenitatis, just to the west-southwest of the crater Menelaus (crater), Menelaus in the Montes Haemus range. The small lunar mare Lacus Hiemalis lies along the southwest rim of Daubrée. The crater was named after French geologist Gabriel Auguste Daubrée, Gabriel A. Daubrée. It was previously designated Menelaus S. This is a horseshoe-shaped formation with the rim open to the northwest. The interior has been flooded by basaltic lava, leaving a level, featureless floor. The rim has a low cut through the southern end, and the eastern rim is attached to low ridges belonging to the Montes Haemus.

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 ...
