May 1, 2020, 2:57 PMWashington, May 1 (Prensa Latina) Scientists discovered more than 500 parent rock patches exposed on narrow ridges that follow a pattern extended along the near side of the Moon, Geology magazine published today.
The above could be evidence of active lunar tectonic processes, possibly the echo of a long-ago impact that nearly shattered the Moon, said Peter Schultz, a professor at Brown University and a co-author of the research.Based on the information gathered during the study, the expert considers that the natural satellite currently creaks and cracks.
“There is an assumption that the Moon is long dead, but we continue to discover that this is not the case,” he said in a statement.
In nighttime observations with the US Space Agency’s (NASA) Lunar Reconnaissance Orbiter’s Diviner instrument, which measures lunar surface temperature, they found that just as concrete-covered cities on Earth retain more heat than the field.
In this way, the bedrock and block layers on the Moon stay warmer at night than regolith-covered surfaces.
And is that most of the lunar surface is covered by this regolith, a layer of crushed rock dust created by the constant bombardment of small meteorites and other impacts.
“The exposed blocks have a relatively short shelf life because regolith accumulation occurs constantly,” said Schultz.
“So when we see them, there must be some explanation of how and why they were exposed in certain places,” he added.
The scientists mapped all the exposures revealed in the Diviner data and found an interesting correlation between the block ridges with a network of cracks found in 2014 by NASA’s GRAIL mission.
These crevices became channels through which magma flowed to the Moon’s surface to form deep intrusions that now appear to be perfectly aligned with the newly found ridges, they pose.
According to Schultz it is almost a one-to-one correlation and that makes us think that what we are seeing is a continuous process driven by things that happen inside the Moon.
