Chandrayaan-3 spacecraft takes flight safely. The communications lines are passing through major roads in the area, including NH5 (Chennai-Perambur-Gummidipundi), NH205 (Chennai-Tiruvallur) SH56 (Perambur-Ponneri), and SH50 (Tiruvallur-Uthukotai), and connections to Vellore, Aarani, Thiruvattipuram, Kancheepuram, Chengalpattu, and Vandalur in Chennai, Kancheepuram, Vellore, and Tiruvallur districts. Notably, Bharat Sanchar Nigam Limited (BSNL) maintains all major communication links connecting Isro’s space centre.

According to the telecom agency, "For the success of the rocket launch, it is essential to ensure the BSNL optical fibre cables are not damaged due to road widening, road repair and other digging activities during the period July 9-14". Chandrayaan-3 is a follow-on mission to Chandrayaan-2 that is aimed make a safe and soft landing on the lunar surface. The mission will conduct in-situ scientific experiments.

ISRO officials noted that the mission life of the lander is one lunar day, which is equal to 14 Earth days. "The date (for soft-landing) is decided based on when there is sunrise on the Moon. While landing, sunlight must be there.

There is sunlight on the Moon for 14-15 days and for the next 14-15 days there is no sunlight," they noted. Chandrayaan-3 consists of an indigenous Lander module (LM), a Propulsion module (PM), and a Rover with the objective of developing and demonstrating new technologies required for Interplanetary missions. The Lander will have the capability to soft land at a specified lunar site and deploy the Rover which will carry out in-situ chemical analysis of the lunar surface during the course of its mobility.
