Valarmathi’s departure comes shortly after India’s historic achievement on August 23, when the Chandrayaan-3 lander module successfully touched down on the moon’s South Pole. This historic milestone solidified India’s position as the fourth nation in the world, following the US, China, and Russia, to successfully land on the lunar surface.

Senior scientist of #ISRO
Smt. N. Valarmathi passes away , aged 64 yrs !
She was best known for her mission countdown at almost every @isro Launches !
Chandrayaan-3 embarked on its lunar journey from the Satish Dhawan Space Centre in Sriharikota on July 14. On August 23, the Chandrayaan-3 Lander Module (LM), comprising the Vikram lander and Pragyan rover, made a historic landing on the lunar surface, marking India as the first country to reach the uncharted South Pole of Earth’s celestial neighbour.
In related developments, ISRO announced that the Pragyan rover on the Moon has entered a dormant state, with plans to wake it up in 14 days. The rover is equipped with two essential payloads: the Alpha Particle X-ray Spectrometer (APXS) and the Laser-Induced Breakdown Spectroscope (LIBS), which were temporarily turned off. These payloads play a crucial role in analyzing the elemental and mineralogical composition of lunar soil and rocks, transmitting valuable scientific data back to Earth.
In the event that the Pragyan rover does not awaken successfully, it will remain on the Moon as India’s enduring lunar envoy, continuing to make significant contributions to lunar exploration.
