Get to know Chandrayaan-3

For Every Indian its a proud moment to see the live telecast of Chandrayaan-3 soft-landing on South Pole of Moon . So are you all ready to watch Chandrayaan-3 soft landing with Tanmay Zone then click this link and set a reminder for you all . Bharat Mata ki Jai ...




Chandrayaan-3 is a follow-on mission to Chandrayaan-2 to demonstrate end-to-end capability in safe landing and roving on the lunar surface. It consists of Lander and Rover configuration. It will be launched by LVM3 from SDSC SHAR, Sriharikota. The propulsion module will carry the lander and rover configuration till 100 km lunar orbit. The propulsion module has Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload to study the spectral and Polari metric measurements of Earth from the lunar orbit.


Lander payloads: Chandra’s Surface Thermophysical Experiment (ChaSTE) to measure the thermal conductivity and temperature; Instrument for Lunar Seismic Activity (ILSA) for measuring the seismicity around the landing site; Langmuir Probe (LP) to estimate the plasma density and its variations. A passive Laser Retroreflector Array from NASA is accommodated for lunar laser ranging studies.


Rover payloads: Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) for deriving the elemental composition in the vicinity of landing site.


The mission objectives of Chandrayaan-3 are:


  1. To demonstrate Safe and Soft Landing on Lunar Surface

  2. To demonstrate Rover roving on the moon and

  3. To conduct in-situ scientific experiments.

To achieve the mission objectives, several advanced technologies are present in Lander such as,


  1. Altimeters: Laser & RF based Altimeters

  2. Velocimeters: Laser Doppler Velocimeter & Lander Horizontal Velocity Camera

  3. Inertial Measurement: Laser Gyro based Inertial referencing and Accelerometer package

  4. Propulsion System: 800N Throttleable Liquid Engines, 58N attitude thrusters & Throttleable Engine Control Electronics

  5. Navigation, Guidance & Control (NGC): Powered Descent Trajectory design and associate software elements

  6. Hazard Detection and Avoidance: Lander Hazard Detection & Avoidance Camera and Processing Algorithm

  7. Landing Leg Mechanism.
