Chandrayaan 3 lander successfully completed key test
Subject : Science and technology
Section: Space technology
Concept :
- According to the Indian Space Research Organisation (ISRO), the lander for the Chandrayaan-3 mission successfully completed the crucial EMI-EMC (Electro – Magnetic Interference/ Electro – Magnetic Compatibility) test at the U.R. Rao Satellite Centre, Bengaluru.
Chandrayaan-3 Lander:
- The Chandrayaan-3 mission is slated to be launched later this year by the GSLV MkIII (Launch Vehicle Mark 3 – LMV3) from the Satish Dhawan Space Centre at Sriharikota.
- According to the space agency, the EMI-EMC (Electro – Magnetic Interference/ Electro – Magnetic Compatibility) 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, as the mission’s complexity calls for establishing radio-frequency (RF) communication links between the modules.
Chandrayaan 3 Mission
- ISRO has announced Chandrayaan-3, a soft-landing mission, after the failure of Vikram Lander under Chandrayaan 2.
- Its moon Lander will be the first to land in southern hemisphere of moon surface.
- While the Orbiter of Chandrayaan 2 is in the lunar orbit, the Lander and Rover failed after the lander crash-landed on lunar surface.
- ISRO is planning to land the Chandrayaan 3 lander at the same location as the Chandrayaan 2 – the lunar South Pole, which is a singularly promising part of the moon’s surface.
- Unlike its predecessor, Chandrayaan-3 will not have an orbiter.
- Chandrayaan-3 interplanetary mission has three major modules: the Propulsion module, Lander module, and Rover.
- Propulsion module:
- It has Spectro-polarimetry of HAbitable Planet Earth (SHAPE) payload to study the spectral and polarimetric measurements of Earth from 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, etc.
- Rover payloads:
- Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) for deriving the elemental composition in the vicinity of the landing site.
