The Moon’s contraction causes fault scarps and moonquakes in the south pole, posing risks for lunar outposts. Findings from a recently published paper led by Smithsonian senior scientist emeritus Thomas R. Watters reveal evidence that the south polar region of Earth’s moon has experienced the effects of the shrinking moon. Global contraction of the moon has caused young lobate thrust fault scarps near and within some regions NASA has proposed for the crewed Artemis III moon landing. The paper, “Tectonics and Seismicity of the Lunar South Polar Region,” published recently in the Planetary Science Journal, associates one of the most...

A spacecraft left behind by US astronauts on the lunar surface could be causing small tremors known as moonquakes, according to a new study. Researchers revealed the previously unknown form of seismic activity on the moon for the first time through an analysis of Apollo-era data using modern algorithms. Massive temperature swings that occur on the moon can cause human-made structures to expand and contract in a way that produces these vibrations, the report suggests. The lunar surface is an extreme environment, oscillating between minus 208 degrees Fahrenheit (minus 133 degrees Celsius) in the dark and 250 degrees Fahrenheit (121...

CHINESE space designers have unveiled plans to build their proposed lunar bases in the volcanic caves of the Moon, allowing for longer-term stays. The researchers believe that these underground hollow lava channels would offer astronauts offer a natural shield against space radiation and the extreme temperatures prevalent on the Moon. This would provide a boost to Beijing’s plans to allow astronauts to stay on the Moon for long periods by 2035. The underground tunnels, also known as lava tubes, were created by molten rock during ancient volcanic eruptions.

Somebody alert Jeff Bezos: the Moon is shrinking. According to a new research study, the Moon may be shrinking as it experiences lunar quakes, known as "moonquakes." Researchers analyzed 28 moonquakes from 1969 to 1977 and came up with the startling observation that eight of the quakes came from "true tectonic activity — the movement of crustal plates," as opposed to impacts from asteroids or rumblings inside the celestial satellite. “We found that a number of the quakes recorded in the Apollo data happened very close to the faults seen in the [NASA’s Apollo and Lunar Reconnaissance Orbiter missions] LRO...
