Chandrayaan-3
Chandrayaan-3 is the successor mission to Chandrayaan-2 to demonstrate full lunar safe landing and locomotion capabilities. It consists of a lander and a probe configuration. It is powered by LVM3 from Sriharikota’s SDSC SHAR. The propulsion module will transport the lander and rover configuration up to 100 km from lunar orbit. The propulsion module carries the Habitable Planet Earth Spectroscopic Polarimetry (SHAPE) payload for studying the spectral and polarimetry of the Earth from lunar orbit.
Chandrayaan-3
Chandrayaan-3 consists of a Landing Module (LM), a Propulsion Module (PM), and a spacecraft for the purpose of developing and demonstrating new technologies required for interplanetary missions. The lander can soft-land on a specific location on the moon, deploy the rover, and perform in-situ chemical analysis on the lunar surface while it’s on the move. Landers and probes carry scientific payloads for conducting experiments on the moon. The main function of the PM is to transport the LM from the launch vehicle jet to the last 100 km polar orbit of the Moon and separate the LM from the PM. The propulsion module also carries a scientific payload as an added value, which is operated separately from the landing module. The launch vehicle identified for Chandrayaan-3 is the LVM3 M4, which will place the integrated module in an elliptical parked orbit (EPO) of approximately 170 x 36500 km.
Chandrayaan 3 Launch Date and Time
India’s third lunar exploration mission, Chandrayaan 3, is gearing up for its launch at 2:35 p.m. on July 14. At the event, the spacecraft will be launched aboard a powerful Mark 3 (LVM3) launch vehicle from the Satish Dhawan Space Center in Sriharikota. The scientific community and people across India and around the world are eagerly awaiting this important milestone in India’s space exploration efforts.

The countdown to this historic mission began on Thursday, raising anticipation for the event. The Indian Space Research Organization (ISRO) announced the start of the countdown on Twitter, saying, “Tomorrow at 14:35:17, we will countdown to the launch.” This announcement has added to the anticipation and excitement for the Chandrayaan 3 mission. The closer we get to the start, the greater the hope that our adventure to the moon will be a success.
Chandrayaan 3 Launch Place in India
The long-awaited launch of Chandrayaan-3, India’s third lunar exploration mission, is scheduled for July 14. The spacecraft will depart from the Satish Dhawan Space Center in Sriharikota, India. This highly significant event not only represented another outstanding achievement in Indian space exploration but also generated great enthusiasm and interest from the scientific community and the general public.
