By C. M. Fortezzo, P. D. Spudis, and S. L. Harrel

The Unified Geologic Map of the Moon, released in 2019 by the USGS, is a groundbreaking and comprehensive representation of the Moon's surface. This map combines data from various sources to create a seamless and globally consistent view of the lunar surface. It's the first time the entire lunar surface has been uniformly classified, providing valuable insights for future missions, scientific research, and education.

The map highlights the Moon's geology at a scale of 1:5,000,000, showcasing different rock types, ages, and geological features. By integrating elevation data and observations from recent satellite missions, it offers a detailed and consistent depiction of the Moon's stratigraphy. This mapping helps resolve inconsistencies in previous maps and presents a unified description of the lunar surface.

This resource is crucial for lunar science, aiding in the planning of future missions and serving as an educational tool for scientists and the public. It represents a significant step towards understanding the Moon's history and preparing for the next era of lunar exploration. The map merges historical data with modern observations, creating a vital reference for the scientific community.
