10. The Lunar Quake Enigma
A moonquake, as its name suggests, is the lunar counterpart of an earthquake. However, the fundamental differences between the Earth and the Moon make these phenomena strikingly distinct. On our planet, active plate tectonics drive seismic activity, causing powerful earthquakes as tectonic plates collide and interact. In contrast, the Moon lacks active plate tectonics, resulting in moonquakes that are comparatively weaker and far less frequent.

Understanding moonquakes is vital not only for lunar exploration but also for gaining insights into the inner workings of Earth. While moonquakes may not shake the lunar surface with the same intensity as earthquakes on Earth, they provide invaluable clues about lunar processes.



11. Tracing the Origins of Moonquakes
Moonquakes can originate from various sources, offering a window into the Moon's geological history. Some are triggered by the impact of meteorites, highlighting the constant bombardment of celestial bodies in our solar system. Others are the result of the moon's crust expanding and contracting as it experiences extreme temperature variations. This constant flexing of the frigid lunar crust can generate seismic events.

The first inkling of moonquakes came from seismometers positioned on the lunar surface during NASA's Apollo missions. These instruments, part of the Apollo 12, 14, 15, and 16 missions, were pivotal in providing the initial data on moonquakes. However, despite their invaluable contributions, these seismometers were powered down in 1977, leaving decades of unanswered questions.


12. Chandrayaan-3: A Bold Leap in Lunar Exploration
In August 2023, Chandrayaan-3 made history by becoming the first lunar lander to reach the Moon's South Pole. But its mission didn't stop at making history; it embarked on a scientific journey that promises to reshape our understanding of lunar dynamics.

The Indian Space Research Organisation (ISRO) sent Chandrayaan-3 to the Moon equipped with a seismometer. This seismometer, a specialized instrument designed to detect and record lunar vibrations, was the key to the recent groundbreaking discovery.

On August 26, 2023, Chandrayaan-3 recorded an event that bore all the hallmarks of a natural lunar quake. The significance of this discovery cannot be overstated, as it marks the first recorded moonquake since 1977. The ISRO has confirmed the event's detection and is currently investigating its source and implications.

This seismic revelation has the potential to unlock a treasure trove of lunar knowledge. Moonquakes, while less intense than their Earthly counterparts, provide scientists with a unique opportunity to peer into the Moon's interior. Seismometers like the one aboard Chandrayaan-3 detect vibrations originating beneath the surface, and these vibrations carry vital information about the composition and structure of the Moon's layers.



14. Deciphering Lunar Clues Through Seismology
Seismology, the study of seismic waves, plays a pivotal role in unraveling planetary mysteries. When seismic waves travel through different materials, they behave differently, offering valuable insights into the properties of those materials. By analyzing these variations, scientists can build a detailed picture of what lies beneath the surface.

On Earth, seismology has allowed us to discern the presence of an inner core and an outer core, even though we've never physically reached these depths. The Moon, on the other hand, remains relatively unexplored in comparison, but we are making steady progress in shedding light on its enigmatic interior.
