What is the main task of India's third moon mission which could not be achieved in its earlier mission? List the countries that…

The primary objective of Chandrayaan-3 was demonstrating a safe and soft landing on the lunar surface, specifically near the unexplored lunar South Pole. This task could not be achieved during Chandrayaan-2 in 2019 due to software glitches and velocity-braking anomalies during the final descent phase, resulting in the hard crash of the Vikram lander.

Countries Achieving Soft Landing India became the fourth nation in history to soft-land on the Moon, joining the former USSR, the United States, and China, followed recently by Japan (SLIM mission in 2024). India is the first to land in the lunar south polar region.

Subsystems of the Spacecraft Launched aboard the LVM3-M4 vehicle—powered by S200 solid boosters, an L110 liquid core, and a C25 cryogenic upper stage—the spacecraft comprised three integrated subsystems:

1. Propulsion Module: Transported the lander-rover composite from injection orbit to a 100-km circular lunar orbit while operating the SHAPE payload.
2. Lander Module (Vikram): Engineered with reinforced legs, enhanced fuel reserves, and advanced navigation instruments including the Laser Doppler Velocimeter (LDV), Lander Horizontal Velocity Camera (LHVC), and autonomous hazard detection and avoidance systems.
3. Rover (Pragyan): A six-wheeled vehicle deployed from the lander, carrying the LIBS and APXS payloads for in-situ elemental analysis of lunar regolith.

Role of the Virtual Launch Control Centre (VLCC) Situated at the Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram, the VLCC provided crucial remote support to the primary Launch Control Centre at Sriharikota. It acquired real-time telemetry streams, performing automated health checks and vehicle dynamics validation during the LVM3 countdown and ascent. By enabling parallel monitoring, simulated trajectory tracking, and automated anomaly-detection algorithms, the VLCC provided mission critical redundancy, ensuring precise vehicle stage separations and accurate orbital insertion.

Chandrayaan-3’s success underscores India’s maturing space ecosystem, proving end-to-end indigenous capability in complex, deep-space exploration.
