Mapping the Moon

Earthsky reports that for the first time, the entire lunar surface has been completely mapped and uniformly classified by scientists from the USGS Astrogeology Science Center, in collaboration with NASA and the Lunar and Planetary Institute. There’s a video below too. They write:

The U.S. Geological Survey (USGS) announced the new Unified Geologic Map of the Moon on April 20, 2020. They said it shows the moon’s surface geology, with rock layers and craters charted “in great detail.” The map is a synthesis of six Apollo-era regional geologic maps, updated with data from more recent moon missions.

USGS said it’s designed to serve as “the definitive blueprint” for lunar science and future human missions to the moon, and to be used by the international scientific community, educators and the public at large.

To create the new digital map, scientists used information from six Apollo-era regional maps along with updated information from recent satellite missions to the moon.

The existing historical maps were redrawn to align them with the modern data sets, thus preserving previous observations and interpretations. Along with merging new and old data, USGS researchers also developed a unified description of the stratigraphy, or rock layers, of the moon. This resolved issues from previous maps where rock names, descriptions and ages were sometimes inconsistent.
