"NASA Scientists Reveal That the Size of the Moon is Shrinking, This is Its Impact on Humans"

Dream - A recent study reveals that the core of the moon is slowly cooling down and shrinking. A study published in the Planetary Science Journal on January 25 found that the circumference of the Moon has shrunk by more than 150 feet. A team of scientists from NASA, Smithsonian, Arizona State University, and The University of Maryland found evidence of the Moon's core gradually cooling down over hundreds of millions of years.

This cooling continued, causing several surface changes around the South Pole of the Moon. The landing site terrain during the Artemis III manned mission has even changed.

"Similar to Grapes"

Reported from Popular Science, the shrinking process this month is similar to the wrinkling process of grapes. The moon also wrinkles as it shrinks.

"Patahan Kerak Bulan" translates to "Moon's Crust Fault" in English.

However, grapes have flexible skin, while the moon has a fragile surface. Fragility causes the formation of fractures where crustal parts push against each other.

"Earthquake"

Due to this shrinkage, faults are formed accompanied by seismic activities such as earthquakes. Any location near the fault zone this month can pose a threat to human exploration there. Just like those living near fault lines on Earth face a greater risk of earthquakes. In the study, the team connected a group of faults in the southern polar region of the moon with the massive moon quakes recorded by Apollo seismometers over 50 years ago.

They use a computer model to simulate the stability of surface slopes and identify areas vulnerable to landslides. "Our modeling shows that shallow moonquakes capable of producing strong ground shaking in the southern polar region may occur due to slip events on existing faults or the formation of new thrust faults," said Thomas R. Watters, co-author of the study and senior scientist emeritus at the Air and Space Museum.

"Earthquake Duration"

Earthquakes on the moon only occur about 100 miles deep within the moon's crust. Unlike earthquakes on Earth that only last a few seconds or minutes, shallow moonquakes can last for hours.

"For now, researchers will continue to map seismic activities on the moon, hoping to discover more potentially hazardous locations for human exploration. NASA's Artemis mission is currently scheduled to launch its first manned flight in September 2025, with a manned moon landing scheduled for September 2026."

"As we get closer to the launch date of the Artemis manned mission, it is important to ensure the safety of our astronauts, equipment, and infrastructure as much as possible.""
colleague of the author of the study and geology expert at the University of Maryland, Nicholas Schmerr.

"This work helps us prepare for what awaits us on the Moon, whether it's engineering structures that can withstand lunar seismic activities or protecting humans from highly dangerous zones."

"pungkasnya" translates to "finally."
