- The Chandrayaan-3 lander has successfully completed the crucial EMI-EMC (electro-magnetic interference/ electro-magnetic compatibility) test at the U.R. Rao Satellite Centre here.
- The Indian Space Research Organisation (ISRO) said on Sunday that the lander for the Chandrayaan-3 mission underwent the test during January 31-February 2.
- According to the space agency, 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
- Chandrayaan-3, India’s third moon mission, is slated to be launched later this year by Launch Vehicle Mark 3 (LMV3) from the Satish Dhawan Space Centre at Sriharikota.
- 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 GSLV MkIII from SDSC, Sriharikota. The propulsion module will carry the lander and rover configuration till 100km lunar orbit.
- 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.
