USGS: First “Unified Geologic Map of the Moon”

Visitor “how about that geology followers?” by David Middleton

USGS Releases First-Ever Complete Geologic Map of the Moon

Launch Date: APRIL 20, 2020

FLAGSTAFF, Ariz. –  Have you ever ever questioned what type of rocks make up these vibrant and darkish splotches on the moon? Properly, the USGS has simply launched a new authoritative map to assist clarify the four.5-billion-year-old historical past of our nearest neighbor in house.

For the primary time, the total lunar floor has been utterly mapped and uniformly categorized by scientists from the USGS Astrogeology Science Middle, in collaboration with NASA and the Lunar Planetary Institute.

The lunar map, known as the “Unified Geologic Map of the Moon,” will function the definitive blueprint of the moon’s floor geology for future human missions and will likely be invaluable for the worldwide scientific neighborhood, educators and the public-at-large. The digital map is accessible on-line now and reveals the moon’s geology in unbelievable element (1:5,000,000 scale).

“Individuals have at all times been fascinated by the moon and after we may return,” stated present USGS Director and former NASA astronaut Jim Reilly. “So, it’s great to see USGS create a useful resource that may assist NASA with their planning for future missions.”

To create the brand new digital map, scientists used info from six Apollo-era regional maps together with up to date info from latest satellite tv for pc missions to the moon. The present historic maps have been redrawn to align them with the trendy knowledge units, thus preserving earlier observations and interpretations. Together with merging new and previous knowledge, USGS researchers additionally developed a unified description of the stratigraphy, or rock layers, of the moon. This resolved points from earlier maps the place rock names, descriptions and ages have been generally inconsistent.

“This map is a end result of a decades-long mission,” stated Corey Fortezzo, USGS geologist and lead creator. “It supplies very important info for brand new scientific research by connecting the exploration of particular websites on the moon with the remainder of the lunar floor.”

Elevation knowledge for the moon’s equatorial area got here from stereo observations collected by the Terrain Digital camera on the latest SELENE (Selenological and Engineering Explorer) mission led by JAXA, the Japan Aerospace Exploration Company. Topography for the north and south poles was supplemented with NASA’s Lunar Orbiter Laser Altimeter knowledge.

I had the great fortune of working with USGS Director and former NASA astronaut Jim Reilly at Enserch Exploration within the 1980’s and early 1990’s.

For normal reference on geologic map-making see: Introduction to Geologic Mapping

After I get a while, I’ll attempt to relate a number of the rock samples from the Apollo missions to the geologic models depicted on the map.

This geologic map is a synthesis of six Apollo-era regional geologic maps, up to date primarily based on knowledge from latest satellite tv for pc missions. It’s going to function a reference for lunar science and future human missions to the Moon. Credit score: NASA/GSFC/USGS.Click on to view map.
