ISRO (Indian Space Research Organisation) has provided updates on the Chandrayaan-3 mission. They used a specialized instrument called RAMBHA-LP to study the lunar environment near the south pole. The results show that there is not much material in that area.
Another instrument called ILSA, onboard Chandrayaan-3, is focused on studying lunar seismic activity. It has not only observed the movements of the rover and other payloads but also recorded an event on August 26 that appears to be natural. ISRO is currently investigating the source of this event.
Additionally, ISRO highlighted that the ILSA payload is the first instance of a Micro Electro Mechanical Systems (MEMS) technology-based instrument on the moon. It includes six high-sensitivity accelerometers made using the Silicon Micromachining process. These sensors detect vibrations caused by movements and convert them into voltage.
The ILSA payload was designed and created in Bangalore at LEOS, with the support of private industries. The deployment mechanism to place ILSA on the lunar surface was developed by URSC (U.R. Rao Satellite Centre) in Bengaluru.
