Chamberlin is a lunarcrater that is located on the far side of the Moon, just past the southeastern limb. It lies to the southeast of Jeans crater, and Moulton crater is attached to the southeastern rim of Chamberlin. This crater is located in a part of the lunar surface that has undergone resurfacing of crater interiors, producing dark-hued crater floors.
The outer rim of this formation is somewhat irregular in shape, with outward bulges to the east and southeast. The southern rim has partly disintegrated, and merges with the northwest rim of Moulton crater. The interior floor of Chamberlin has been flooded by basaltic-lava, producing a nearly flat surface with a lower albedo than the typical lunar surface. The interior is otherwise devoid of features of interest, and is marked only by a few tiny craterlets.
Satellite craters
By convention these features are identified on Lunar maps by placing the letter on the side of the crater mid-point that is closest to Chamberlin crater.
The traditional lunar profile was to launch a spacecraft toward the moon, have its landing stage brake it to a lunar landing, then have the ascent stage launch the re-entry capsule from the lunar surface back toward the earth.
James A. Chamberlin and James T. Rose of STG proposed adapting the improved Mercury spacecraft to a 35,000-pound payload, including a 5,000-pound "lunar lander." This payload would be launched by a Saturn C-3 in the lunar orbit rendezvous mode.
Ascent of the LM from the lunar surface, rendezvous, and docking with the CSM in orbit were performed as planned, with docking at 3:36 p.m.
