What were the objectives of the Chandrayaan-3 mission?

Chandrayaan-3 is a follow-on mission to Chandrayaan-2. As per ISRO’s official website, the three main objectives of Chandrayaan are:

1. To demonstrate a Safe and Soft Landing on Lunar Surface
2. To demonstrate Rover roving on the moon and
3. To conduct in-situ scientific experiments.

How did Chandrayaan-3 achieve all the objectives?

Chandrayaan-3 comprises an indigenous Lander module (LM), a Propulsion module (PM), and a Rover. The purpose of Chandrayaan-3 is to develop and demonstrate new technologies necessary for interplanetary missions. ISRO says that to achieve the various mission objectives, several advanced technologies are present in Lander such as:

• Altimeters: Laser & RF based Altimeters
• Velocimeters: Laser Doppler Velocimeter & Lander Horizontal Velocity Camera
• Inertial Measurement: Laser Gyro based Inertial referencing and Accelerometer package
• Propulsion System: 800N Throttleable Liquid Engines, 58N attitude thrusters & Throttleable Engine Control Electronics
• Navigation, Guidance & Control (NGC): Powered Descent Trajectory design and associate software elements
• Hazard Detection and Avoidance: Lander Hazard Detection & Avoidance Camera and Processing Algorithm
• Landing Leg Mechanism.

Chandrayaan-3 was the third and one of the most important lunar missions of India. One of the most economical space missions, Chandrayaan-3 costs less than any blockbuster film. According to the former Chairman of ISRO, K Sivan, the total cost of Chandrayaan-3 is Rs. 615 crore. The lander, rover, and propulsion cost around Rs. 215 crore and the launch costs around Rs. 365 crore.
