In order to mark the day of Chandrayaan Mission-3.0 landing on the Moon’s South Pole, Prime Minister of India Shri Narendra Modi has declared 23rd of August as National Space Day. PM Modi while addressing the Team at Indian Space Research Organisation (ISRO) for their remarkable achievement for the success of Chandrayaan Mission 3.0 at ISRO Telemetry Tracking & Command Network Mission Control Complex in Bengaluru had congratulated the Space heroes of ISRO for achieving the milestone by landing in the South Pole of the Moon which was a dream for human civilisation. This mission will not only help India but also the whole space fraternity to gain knowledge for further exploration of the Moon.

A brief about Chandrayaan Mission 3.0:
Chandrayaan-3 is a follow-on mission to Chandrayaan-2 which was launched on 14th July 2023 from ISRO’s launch station at Sriharikota. It consists of Lander and Rover configuration. The propulsion module will carry the lander and rover configuration till 100 km lunar orbit. The propulsion module has Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload to study the spectral and Polari metric measurements of Earth from the lunar orbit.The mission objectives of Chandrayaan-3 is to demonstrate Safe and Soft Landing on Lunar Surface, demonstrate Rover roving on the moon and conduct in-situ scientific experiments.
