Chandrayaan-3 is ready: India’s moon mission clears test that ensures it can work in space

India's lunar mission Chandrayaan-3 achieves another milestone; Clears key test on functioning of satellite in space. In a boost to India's lunar mission, Chandrayaan-3 has successfully underwent EMI-EMC (Electro-Magnetic Interference/ Electro-Magnetic Compatibility).

Chandrayaan-1, the first Indian deep space mission, was launched to orbit the Moon and to dispatch an impactor to the surface. Scientific goals included the study of the chemical, mineralogical and photogeologic mapping of the Moon.

Chandrayaan-2 is an Indian mission to send an orbiter, lander, and rover to the Moon. The lander crashed in the Moon's southern hemisphere in 2019. The orbiter is mapping the Moon's topography, investigating the surface's mineralogy and elements, studying the lunar exosphere, and looking for signatures of water ice.

Is Chandrayaan-1 success or failure?

The spacecraft operated for less than two years: 312 days as opposed to two years. However, the Chandrayaan-1 was successful in achieving at least 95 per cent of its objectives.

Chandrayaan-3. 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.06-Dec-2022

India wants to look at the Moon's surface, particularly in regions that haven't seen sunlight in a few billion years. These darker regions of the lunar surface may contain ice and rich mineral deposits, according to scientists and astronomers.28-Nov-2022

The agency is also scheduled to launch its third lunar mission, Chandrayaan-3, in June 2023, which is essential for India's future interplanetary explorations.02-Jan-2023

Chandrayaan-3 is set to be launched on GSLV Mk-III in June this year. The mission has been delayed as Isro continues to test the rover, which is expected to be more robust than the last two missions.02-Jan-2023

Description. Chandrayaan 3 is an ISRO (Indian Space Research Organization) mission with the primary objective of putting a lander and rover in the highlands near the south pole of the Moon in 2023.

The Indian Space Research Organisation (ISRO) on Sunday announced that Chandrayaan-3 successfully underwent EMI/EMC between January 31 and February 2.

By India Today Web Desk: In a boost to India’s moon mission, Chandrayaan-3 successfully underwent EMI/EMC (Electro - Magnetic Interference/ Electro-Magnetic Compatibility) at U R Rao Satellite Centre, Bengaluru. The test was conducted between January 31 and February 2, the Indian Space Research Organisation (ISRO) announced on Sunday.

WHAT IS EMI-EMC TEST?

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, Isro said in a statement.

Chandrayaan-3 interplanetary mission has three major modules: the Propulsion module, Lander module, and Rover. "The mission's complexity calls for establishing radio-frequency (RF) communication links between the modules," Isro said.

During the EMI/EMC test, launcher compatibility, antenna polarization of all RF systems, standalone auto compatibility tests for orbital and powered descent mission phases, and Lander & Rover compatibility tests for the post-landing mission phase were ensured.

The Isro said that the performance of the systems was found to be satisfactory.

Chandrayaan-3 is a follow-up to the Chandrayan-2 mission that will demonstrate end-to-end capability in safe landing and roving on the lunar surface and consists of a lander-rover configuration.

While the Indian space agency is yet to say anything about the final launch dates, it is likely to be in the second or third quarter of 2023.

The mission is aimed at better understanding the Moon's composition. Isro has laid out three main objectives for the mission, which include demonstrating a safe and soft landing on the lunar surface, demonstrating the rover's roving capabilities on the moon and performing in-situ scientific observations.
