When a boulder drops down the slope of the rock on the moon, it kicks the moon dust, leaving the Ejecta signaling herring bone model.
In a recent study, scientists have also taken the evidence of such a boulder waterfall. They set 245 fresh tracks created as boulders, rolling, bouncing and slipping down the crater walls.
“For a long time there was such a belief that the moon is geologically dead. Our study shows that boulders with size fluctuate [from] between 10 to hundreds of meters and [with] Over time, weights from their seats have passed from their seats, ”said Sivaprahasam Vijayan, the main author and associate professor of the study at the physical research laboratory in Ahmedabad, India.” Just as it is important to know how recently these boulder fall events are to understand periods when active geological agents have been. “
Watch Boulder Falls
When the lunar boulders bounce, they scan bright, face without underground material and carry it to the surface. As a result, fresh Boulder Fall tracks look brighter than older ones.
“It can be found that the Boulder fall is recently, given the boulder falling eject,” said Senthil Kumar Perumal, the main scientist of the planetary science group, at the National Institute for Geophysical Research in Hyderabad, India, which did not attend a new study.
To determine the relatively latest Boulder tracks, Vijayan and his colleagues first manually searched for thousands of moon surface images from 40 ° S to 40 ° north latitude. In these latitudes, the sun forces bright boulder tracks that are different from the rest of the lunar surface. When they found the track, the researchers examined the appropriate images made by the NASA Moon Retelligence Orbits Narrow Angle Camera 2009-2022.
The researchers further evaluated the age of the tracks by exploring the regions with both the Boulder Fall Ejecta (BFE) and with separate impact exhaust blankets. (Such blankets, nicknamed “moon fossils”, have long been used to evaluate the age of the effects of the effects.) Vijayan and his colleagues analyzed the craters for about 400,000 years – which means that the BFE tracks are newer.
Finally, scientists found possible seismic failures or stroke craters that could have caused a boulder waterfall.
Moon map
The new Boulder Falls geological map announced by Icarus emphasizes seismically active sites and fresh strokes on the moon. Researchers say these regions can be a potential landing place for future lunar missions, focused on the latest surface and underground activities.

The authors of the study are planning to integrate artificial intelligence methods into another iteration of their work, but finally, according to Vijayan, the next step said to determine whether the cause is the cause [of a fall] There is endogenous or exogenous that can be achieved by deployment of additional seismics on upcoming missions. ”
Kumar agreed. “We have to have a large network of seismometers covering the full [moon] It has been constantly watching seismic activities for several decades, ”he said.
