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.
