Chandrayaan-3 Mission: Three Modules

The Chandrayaan-3 mission of exploring the third lunar is set by the Indian Space Research Organization (ISRO).

The mission comprises three major modules: the Propulsion module, Lander, and Rover module. Also, the three modules require radio-frequency (RF) based communication to link.

On February 24, the CE-20 cryogenic rocket engine’s fire test has successfully conducted that powers the cryogenic upper stage (CUS) of the satellite launch vehicle named GSLV-Mark-3 or LVM3 at ISRO located at Mahendragiri, Tamil Nadu.

The engine fire test was conducted at a high altitude and lasted for 25 seconds as planned. During the test, all propulsion parameters met the standards.

However, for conducting integrated flight training on a full scale, the cryogenic engine will be further added with the stage structures, propellant tanks, and fluid lines, according to ISRO.

The mission second module lander successfully conducted an Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) test between January 31 and February 3.

The goal of conducting a lander test is to determine that satellite components will generally function in space and are compatible with the anticipated electromagnetic fields. This test gave a significant turning point to the development of the satellites.

The mission’s lander module EMI/EC test ensures that the antenna polarization feature, launcher compatibility, auto compatibility tests for orbital, and lander & rover compatibility tests for post-landing missions perform satisfactorily.
