Chandrayaan-3 lander undergoes key test successfully

ISRO’s Chandrayaan-3 lander has successfully undergone the Electro-Magnetic Interference/Electro-Magnetic Compatibility (EMI/EMC) test at the U R Rao Satellite Centre here.

The EMI/EMC test is conducted for satellite missions to ensure the functionality of the satellite subsystems in the space environment and their compatibility with the expected electromagnetic levels.

This test is a major milestone in the realisation of the satellites.

The Chandrayaan-3 mission is expected to be launched in August 2023.

About Chandrayaan-3: It 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 GSLV MkIII from SDSC, Sriharikota.

The propulsion module will carry the lander and rover configuration till 100km lunar orbit.

Further, the propulsion module has Spectro-polarimetry of HAbitable Planet Earth (SHAPE) payload to study the spectral and polarimetric 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.
