Exploring India’s Lunar Missions: The Differences Between Chandrayaan 3 and Chandrayaan 2

Enhanced Specifications: Chandrayaan 3 is equipped with two lander hazard detection and avoidance cameras, which are more robust than the single camera carried by Chandrayaan 2.

Lander Leg Mechanism: Chandrayaan 3 underwent rigorous testing of its lander leg mechanism to ensure its strength and performance.

Mission Components: Chandrayaan 2 consisted of an Orbiter, Vikram Lander, and Pragyan Rover, while Chandrayaan 3 comprises a Lander module (LM), Propulsion module (PM), and a Rover, with the orbiter from Chandrayaan 2 being utilized for the new mission.

Payload: Chandrayaan 3 carries a payload called Spectro-polarimetry of Habitable Planet Earth (SHAPE), equipped with the propulsion model, emphasizing scientific objectives.

Learning from Mistakes: ISRO has thoroughly analyzed the failure of Chandrayaan 2 and identified a software malfunction as the cause of the unsuccessful landing. Lessons learned from this incident have been applied to improve the mission’s chances of success.

Soft Landing Focus: The primary objective of Chandrayaan 3 is to achieve a successful soft landing on the lunar surface, which was not accomplished during the previous mission.

Lunar Exploration Ambition: Chandrayaan 3 aims to demonstrate India’s capability of soft landing and roving on the lunar terrain, positioning the country among a select group of nations that have achieved this feat.

International Elite Club: Successful completion of Chandrayaan 3 would make India the fourth nation, following China, the USA, and the former Soviet Union, to achieve a soft landing on the Moon.

Corrective Measures: ISRO has implemented corrective measures based on the lessons learned from Chandrayaan 2 to minimize the risk of failures and improve the chances of achieving the desired scientific objectives during Chandrayaan 3.
