Chandrayaan-3 Mission Overview
On Wednesday, August 23, 2023, India achieved a historic milestone with the successful soft landing of Chandrayaan-3 on the Moon's surface, specifically in the South Pole area. Prime Minister Narendra Modi highlighted that this achievement reflects the aspirations and capabilities of 140 crore Indians. Sharing a post on X by the Indian Space Research Organization, he remarked:"“Chandrayaan-3's triumph mirrors the aspirations and capabilities of 140 crore Indians. To new horizons and beyond! Proud moment for 🇮🇳.”"

About Chandrayaan-3
Chandrayaan-3, a follow-on mission to Chandrayaan-2, was launched by the Indian Space Research Organization (ISRO) with the primary objectives of:


 * Demonstrating a safe and soft landing on the lunar surface.
 * Exploring the Moon's surface with a rover.
 * Conducting in-situ scientific experiments.

The mission includes a lander, a rover, and a propulsion module.



Mission Profile

 * Launch Date: July 14, 2023, at 9:05:17 UT (2:35 p.m. India Standard Time)
 * Launch Vehicle: Geosynchronous Satellite Launch Vehicle GSLV Mark 3 (LVM 3)
 * Launch Site: Satish Dhawan Space Center, Sriharikota, Andhra Pradesh
 * Orbit: Initial elliptic parking orbit of 170 x 36,500 km
 * Lunar Orbit: Propulsion module adjusted the lander/rover into a 100 km circular polar lunar orbit
 * Touchdown Date: August 23, 2023

The lander and rover were designed to operate for one lunar daylight period (about 14 Earth days). The propulsion module remains in lunar orbit to act as a communications relay satellite, supported by Chandrayaan-2 as a backup relay.

Propulsion Module (PM)

 * Function: Transported the lander and rover from injection orbit to 100 km lunar orbit
 * Scientific Payload: Spectro-polarimetry of Habitable Planetary Earth (SHAPE) to study Earth's spectral and polarimetric measurements from lunar orbit

Lander Module (LM)

 * Payloads:
 * Chandra’s Surface Thermophysical Experiment (ChaSTE): Measures thermal conductivity and temperature
 * Instrument for Lunar Seismic Activity (ILSA): Measures seismicity around the landing site
 * Langmuir Probe (LP): Estimates plasma density and its variations
 * Laser Retroreflector Array (NASA): For lunar laser ranging studies

Rover

 * Payloads:
 * Alpha Particle X-ray Spectrometer (APXS): Derives elemental composition near the landing site
 * Laser Induced Breakdown Spectroscope (LIBS): Analyzes elemental composition in the vicinity
