Summary
This map shows the geology in and around potential early Apollo landing site 1 in the lunar equatorial belt. The Maskelyne DA region, at the southeastern edge of Mare Tranquillitatis, is in an area transitional between mare and terra. Patches of typical terra material occur on northwest-trending ridges, and typical heavily-cratered mare material occurs only in the east-central part of the region. The terrain in the rest of the region, including the potential landing site, is exceptionally smooth and deficient in craters more than 50 m (meters) in diameter. A large cratered dome, possibly indicative of late-stage volcanism, occurs in the southern part of the region. Telescopically, the terrain over most of the region resembles that [...]
Summary
This map shows the geology in and around potential early Apollo landing site 1 in the lunar equatorial belt. The Maskelyne DA region, at the southeastern edge of Mare Tranquillitatis, is in an area transitional between mare and terra. Patches of typical terra material occur on northwest-trending ridges, and typical heavily-cratered mare material occurs only in the east-central part of the region. The terrain in the rest of the region, including the potential landing site, is exceptionally smooth and deficient in craters more than 50 m (meters) in diameter. A large cratered dome, possibly indicative of late-stage volcanism, occurs in the southern part of the region. Telescopically, the terrain over most of the region resembles that of mare areas with intermediate albedo; hence, at a scale of 1:1,000,000 the materials here were mapped as unit Ipm2 of the Procellarum Group (Wilhelms, 1965).
Digitized 1:100,000-scale geologic map of the Maskelyne DA region of the Moon. Originally mapped on Photomap ORB II-2 (100) base imagery. The scanned map sheet was imported into ArcGIS Pro and georeferenced to the more current 2015 global LOLA Kaguya shaded relief mosaic basemap. Contacts and geologic units were digitized and attributed based on type and unit name.
