3013) Chandrayaan-3 Mission, ISRO India, Karnataka:   Karnataka Postal Circle of India Post has issued a Special Cover (SC) from its Bengaluru Post Office: Date of Special Cover issue: 23.08.2023:

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. 

Chandrayaan-3 consists of an indigenous Lander module (LM), Propulsion module (PM) and a Rover with an objective of developing and demonstrating new technologies required for Inter planetary missions: 

It consists of a Lander and Rover configuration

It was launched by LVM3 from SDSC SHAR, Sriharikota. 

The propulsion module carried 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 payloadsChandra’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 payloadsAlpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) for deriving the elemental composition in the vicinity of landing site.

The Lander had the capability to soft land at a specified lunar site and deploy the Rover which carried out in-situ chemical analysis of the lunar surface during the course of its mobility. 

The Lander and the Rover have scientific payloads to carry out experiments on the lunar surface. 

The main function of PM was to carry the LM from launch vehicle injection till final lunar 100 km circular polar orbit and separate the LM from PM. 

Apart from this, the Propulsion Module also has one scientific payload as a value addition which was operated post separation of Lander Module. 

The launcher identified for Chandrayaan-3 is LVM3 M4 which will place the integrated module in an Elliptic Parking Orbit (EPO) of size ~170 x 36500 km.

The mission objectives of Chandrayaan-3 are:

- To demonstrate Safe and Soft Landing on Lunar Surface

- To demonstrate Rover roving on the moon and

- To conduct in-situ scientific experiments.

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

Altimeters: Laser & RF based Altimeters.

Velocimeters: Laser Doppler Velocimeter & Lander Horizontal Velocity Camera.

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

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

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

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

Landing Leg Mechanism.

To demonstrate the above said advanced technologies in earth condition, several Lander special tests have been planned and carried out successfully viz.

Integrated Cold Test - For the demonstration of Integrated Sensors & Navigation performance test using helicopter as test platform

Integrated Hot test – For the demonstration of closed loop performance test with sensors, actuators and NGC using Tower crane as test platform

Lander Leg mechanism performance test on a lunar simulant test bed simulating different touch down conditions.

The objectives of scientific payloads planned on Chandrayaan-3 Lander Module and Rover are provided below:

Objectives:

1. Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA) Langmuir probe (LP) To measure the near surface plasma (ions and electrons) density and its changes with time

2. Chandra’s Surface Thermo physical Experiment (ChaSTE) To carry out the measurements of thermal properties of lunar surface near polar region.

3. Instrument for Lunar Seismic Activity (ILSA) To measure seismicity around the landing site and delineating the structure of the lunar crust and mantle.

4. LASER Retroreflector Array (LRA) It is a passive experiment to understand the dynamics of Moon system.

Rover Payloads:

Objectives:

1. LASER Induced Breakdown Spectroscope (LIBS) Qualitative and quantitative elemental analysis & To derive the chemical Composition and infer mineralogical composition to further our understanding of Lunar-surface.

    1. No. But this is a special cover on Chandrayaan 3 issued by the Karnataka postal Circle as Sriharikota is in Karnataka itself. A Special Cover was issued on Chandrayaan 2 by the West Bengal Circle of India Post. I have that in my collection & on the Blog.
