달의 크기가 점점 줄어들고 있다! 과학자들 멘붕!
Updated: November 19, 2024
Summary
The moon, while appearing consistent from Earth, is actually slowly shrinking in size due to the cooling of its core leading to volume reduction. This shrinkage causes the moon's surface to develop wrinkles and experience frequent lunar quakes. The Artemis mission plans to land humans on the moon's South Pole for its resources, but faces challenges from seismic activity and possible destruction of the moon base due to the moon's changing surface. Despite preparations, the mission's timeline has been delayed to 2026, and uncertainties remain for establishing a moon base camp by 2030.
The Unchanging Moon
The moon, which has always appeared the same in the night sky, is actually continuously changing in size. Scientists have recently discovered that the moon is slowly decreasing in size.
Reasons for Moon Shrinking
The moon has been shrinking by about 45 meters over the past few billion years since its formation. The main reason for this continuous shrinking is the cooling of its core, causing volume reduction around the mantle as it transitions from liquid to solid.
Effects of Shrinking on Moon's Surface
As the moon's volume decreases, its surface develops wrinkles similar to raisins turning into raisin wrinkles. However, the moon's surface is fragile, creating the potential for frequent earthquakes and dangerous lunar quakes. This poses a threat to humanity despite no one living on the moon currently.
Artemis Mission Preparation
Scientists are preparing the Artemis mission to send humans to the moon. The mission aims to land in the vulnerable region of the moon's South Pole due to its rich ice deposits that can provide water, fuel, and oxygen. However, challenges such as the region's vulnerability to seismic activity and surface distortion due to lunar shrinkage are concerns for the mission's safety.
Mission Risks and Future Plans
The Artemis mission faces risks of landing in a vulnerable area, with potential consequences for the safety of astronauts, and the destruction of the moon base camp. Despite the preparations, the mission's timeline has been pushed to 2026, and construction of a moon base camp by 2030 poses further challenges and uncertainties for human lunar exploration.
