“ISRO’s Lunar Seismic Activity Instrument Records Mysterious Event on Moon’s Surface”
Point 1: The Instrument of Lunar Seismic Activity (ILSA) payload on Chandrayaan-3’s lander module Vikram detected a natural event on the lunar surface on August 26, 2023, which is currently being investigated by ISRO.
Elaboration: The ILSA payload, equipped with high-sensitivity accelerometers, recorded vibrations caused by the movements of the rover and other payloads. In addition to these expected vibrations, ILSA also captured an unidentified natural event, the source of which is still unknown. ISRO is conducting further investigations to determine the nature of this event.

Continuation: The ILSA payload on Chandrayaan-3’s lander module is the first-ever instance of a Micro Electro Mechanical Systems (MEMS) technology-based instrument deployed on the moon. It utilizes a cluster of six high-sensitivity accelerometers fabricated using Silicon Micromachining process.
The primary objective of ILSA is to measure ground vibrations generated by natural quakes, impacts, and artificial events. The recorded vibrations during the rover’s navigation on August 25, 2023, were successfully captured. Additionally, ILSA also recorded an intriguing natural event on August 26, 2023, which is currently under investigation.
The ILSA payload was designed and realized at LEOS in Bangalore with support from private industries. The deployment mechanism for placing ILSA on the lunar surface was developed by URSC in Bengaluru.
India’s achievement of successfully landing the Chandrayaan-3 lander module on the moon’s South Pole on August 23, 2023, made it the fourth country in history to accomplish this feat after the US, China, and Russia. Prime Minister Narendra Modi also declared that the touchdown spot of the Vikram lander would now be known as the ‘Shiv Shakti’ point.
