Lunar regolith at Tranquillity Base
The regolith at Tranquillity Base is a layer of fragmental debris that ranges in thickness from about 3 to 6 meters. The thickness of the regolith and the exposure histories of its constituent fragments can be related, by means of a relatively simple model, to the observed crater distribution.
Preliminary geologic investigation of the Apollo 12 landing site: Part A: Geology of the Apollo 12 Landing Site
This report provides a preliminary description of the geologic setting of the lunar samples returned fromt he Apollo 12 mission. A more complete interpretation of the geology of the site will be prepared after thorough analysis of the data.
Geologic setting of the lunar samples returned by the Apollo 11 mission
The Apollo 11 LM landed approximately 20 km south-southwest of the crater Sabine D in the southwestern part of Mare Tranquillitatis ( fig. 3-1 ). The landing site is 41.5 km north-northeast of the western promontory of the Kant Plateau (ref. 3-1 ), which is the nearest highland region. The Surveyor 5 spacecraft is approximately 25 km north-northwest of the Apollo 11 landing site, and the impact crater formed by Ranger 8 is 68 km northeast of the landing site.
