Chandrayaan-3, building upon Chandrayaan-2, aims to demonstrate advanced lunar exploration capabilities. Consisting of a Lander and Rover configuration, this mission endeavors to uncover the Moon’s secrets through scientific payloads and cutting-edge technology.
- The indigenous Lander module is the centerpiece of Chandrayaan-3.
- Designed for soft landing, it carries scientific payloads to study lunar phenomena.
- Propulsion Module (PM) carries the Lander and Rover configuration to a 100 km lunar orbit.
- PM features the Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload, analyzing Earth’s spectral and polarimetric measurements from lunar orbit.
- Chandra’s Surface Thermophysical Experiment (ChaSTE): Measures thermal conductivity and temperature.
- Instrument for Lunar Seismic Activity (ILSA): Gauges seismicity around the landing site, probing lunar crust and mantle.
- Langmuir Probe (LP): Estimates plasma density and variations.
- Laser Retroreflector Array (LRA): NASA’s passive experiment for lunar laser ranging studies.
- Alpha Particle X-ray Spectrometer (APXS): Derives elemental composition of lunar soil and rocks.
- Laser Induced Breakdown Spectroscope (LIBS): Provides insights into chemical and mineral composition near the landing site.
Advanced Technologies and Objectives:
- Chandrayaan-3 aims to demonstrate advanced technologies for interplanetary missions.
- Lander employs altimeters, velocimeters, inertial measurement, propulsion systems, navigation, and hazard detection for safe landing.
- Mission objectives encompass safe landing, rover mobility, and in-situ scientific experiments.
- Chandrayaan-3’s mass is 3900 kg, with Propulsion Module at 2148 kg and Lander Module at 1752 kg.
- Power generation ranges from 50W (Rover) to 758W (Propulsion Module).
- Communication involves IDSN links for Propulsion Module and Lander, with contingency link to Chandrayaan-2 Orbiter.
Scientific Payloads Significance:
- Lander payloads study lunar plasma, thermal properties, seismic activity, and cosmic dynamics.
- Rover payloads unravel elemental and mineral composition, enriching lunar geological knowledge.
- Chandrayaan-3 contributes to exploring lunar history, Solar System evolution, and potential for future lunar bases.
