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

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

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.
