Launch and Mission:
- ISRO launched Chandrayaan-3 on July 14, 2023, marking India’s third lunar mission.
- Successfully achieved a soft landing near the lunar South Pole on August 23, 2023.
- Mission objectives were threefold: demonstrate safe lunar landing, rover mobility, and on-site experiments.
Achievements:
- Chandrayaan-3 successfully executed a soft landing in the vicinity of the lunar South Pole.
- India became the fourth country to successfully achieve a soft lunar landing.
Launch Details:
- Chandrayaan-3 was launched by LVM3 from Satish Dhawan Space Centre, Sriharikota.
Module Composition:
- The spacecraft consisted of three modules: Propulsion (PM), Lander (Vikram), and Rover (Pragyan).
Slingshot Maneuver:
- Ingenious technique: spacecraft circled Earth multiple times, leveraging its gravity to gain speed.
- This reduced the need for excessive fuel, optimising the mission’s efficiency.
Lunar Approach:
- Entered lunar orbit and progressively neared the moon using a series of planned orbits.
Landing and Rover Deployment:
- Lander successfully executed a soft landing near the lunar South Pole.
- Rover named Pragyan was deployed to explore the moon’s surface for 14 Earth days.
Payloads:
- Propulsion Module: Carried SHAPE payload for Earth measurements from lunar orbit.
- Lander Module: Equipped with ChaSTE (thermal conductivity), ILSA (seismic activity), and LP (plasma density) payloads.
- Rover: Held APXS (elemental composition) and LIBS (spectroscopy) payloads for surface analysis.
Significance and Future Impact:
- Chandrayaan-3 showcases ISRO’s dedication to advancing lunar exploration.
- The gathered data is expected to contribute to NASA’s Artemis program under the Artemis Accord as India is also signatory to Artemis Accord.
