More than 3 billion years ago, when the volcanic horse of the moon (the dark “seas) were formed, the moon was full of tectonic and coatquakes activities that shook its surface. The proof of these events that arouse on the ground can be seen on the nearby side of the moon in the form of long characteristics called Rugne, created when the basalt lava sheets are collapsed and settled towards the depressed center of the pelvis that cradled the Mary.
But while the moon does not host active volcanoes, it could be even more geologically active than it seems. In recent years, studies on the horse surfaces have identified a new type of functionality nicknamed small horse ridges or smrs, which seem to have been formed recently, which implies that the small scale tectonic activity can continue on the moon today.
In the January 2025 of The Planetary Science JournalA team of researchers from the Smithsonian Institution in Washington, DC and of the University of Maryland in College Park, present the most complete investigation of small mare ridges, examining them on both near and far sides of the moon. Their results provide evidence of the modern tectonic activity that could affect the next moon missions.
Current moonquakes
The SMRs are thought to be formed in part by the global stress of the contraction during the moon: while the interior of the moon cools down, the world narrows very slowly – equal to about 150 feet (50 meters) in the last hundreds of millions of years. It is thought that the tides created by the changing effect of terrestrial gravity throughout the inclined and elliptical orbit of the moon and the cooling of the horse in advance they play a role in forming SMRS.
The recently discovered crests are generally 330 feet wide (100 meters) and up to 3,300 feet (1,000 meters in length, too small to be seen by the earth. But using the richly detailed images of the NASA lunar reconnaissance orbit, i Researchers identified 1,120 SMR on the neighbor.
The new work expands the study of SMRs towards the farthest lunar side to provide a more complete picture of modern lunar tectonic activity. Arside has a fewer Mary number that the neighbor. In fact, only two, Engenii sea and Moscovione Sea, have been officially appointed. The huge basin of the South-Poro pole, which covers most of the southern hemisphere of Faride, contains many small horse patches that have made it possible to expand SMR studies to the Aaride.
Since the farce crust is thicker, the volcanic eruptions that created its horse patches occurred later on the formation of the classic next Mary. Curiously, the Mary of Faride is without long rough crests common to the nearby side. This may be due to the thicker crust of the thicker part, which is less flexible than the nearby crust and has not collapsed under the weight of the basalt that lies on it.
A precious resource
For their SMR investigations, the team of researchers (Cole Nypaver and Thomas Waters of Smithsonian and Jaclyn Clark of the University of Maryland) has used a portal available to the public to access the high -resolution images and data collected by millions of Altimeter laser shots fired the moon of NASA’s lunar reconnaissance orbit.
A total of 266 SMR Faride were identified, mainly in the southern hemisphere. This is about a quarter of the number of SMrs near the side, but a good sampling considering that there are many less basalt patches of the opposite side.
To determine the ages of the SMRs, the researchers used a couple of methods. In a method, they examined the images of orbter of lunar reconnaissance to count the craters near the characteristics. A smaller number of craters indicate a younger surface, as less time has passed for the accumulation of meteoroid impacts.
In another method, the team studied small craters who were bisecting a smr. Small craters have a shorter duration than the larger ones because they are faster filled with regolite launched regolite. Therefore, finding a small crater in two from an SMR indicates that the crest is geologically young.
Inside the southern Polo-Aitkin basin and the craters of Bolyai and Aitken, the team found 13, 20 and 32 small craters respectively, in two. Comparing the expected duration of small craters in these three positions, they calculated that the SMRs that intersect the craters formed 110, 14 and 34 million years ago. A derived age of millions of years may seem ancient, but on the lunar time of 4.6 billion years, the formation of these SRS is a surprisingly recent event and shows that the moon could still be seismically active.
Moonquakes and space vehicles
The potential of current moon cases in the southern polar region has clear implications for Artemis landings in crew planned in the near future. A small occasional murmur of a moon castle will be a scientific treatment, which allows seismic tools provided by Artemis to study the geological structure of the lunar interiors. However, a “large” lunar could damage the infrastructure of a lunar scientific base. The cracks in the walls that would be simple annoyances after a terrestrial earthquake would have much more disturbing consequences in the environment of the ruthless emptiness of the moon.
The resilience of the moonquake of the Spacex Starship human landing system also becomes fundamental if the lunar tectonic activity is still present and periodically the south pole are held. The booth of the room of the spaceship similar to a monument will tower more than 110 feet (33 meters) above the surface. As depicted in current illustrations, the imprint of small landing trolleys offers little stability from the seismic roll of a large moon castle. A rope of Toppled enters the destiny for the crew.
If Moonquakes is a frequent reality, more robust redesigned HLS HLS clothing will be heavier but it will reduce the payload transported to the moon. He would also have an impact on the plans to deliver scientific goods and large rover to the south lunar pole.
Lunar Lunar Lanar Lunar Lunar Lunar is shorter than The Starship HLS and its landing equipment has a proportionally wider and more stable imprint. However, the development of the Lander Blue Moon is several years behind the HLS spaceship and the Blue Moon load capacity is significantly lower than that scheduled for the spaceship.
Previous seismic studies 50 years ago of Apollo’s Lunar Seismic Lunar experiment indicated that moon cases are shallow events related to the position of the Lobate escarpments – another type of soil with busty origins. These Scarps, generally about 130 feet (40 meters) in height, are formed when the interior of the moon cools and narrows, leaving the crust more fragile with little support. The crust at the end starts, part of it riding and beyond another part. SMR morphology is similar to the largest lobed shoes and also indicates their source of regional lunar seismic activity.
Avoidance area
A conclusion from the study of SMRs is that these regions should be avoided by future crew landings until the stability of these regions is fully understood. Nypaver and his colleagues suggest that instead of deploying seismic tools near SMRS in Crewed Artemis missions, these regions should be carefully studied by unqualified landing flew by international partners or by the NASA commercial payload Lunar service program.
An intriguing point on the discovery of small ridges of widespread mares is that the portal used in the research, the Loc QuickMap tool based on the web, is available for any lunar enthusiast.
