Chandrayaan-3: ISRO successfully conducts key rocket engine test


Indian Space Research Organisation has stepped towards a new success as it conducted the flight acceptance hot test of the CE-20 cryogenic engine. ISRO on February 24 tested the engine that will power the cryogenic upper stage of the launch vehicle for the Chandrayaan-3. The Bengaluru-headquartered national space agency informed that the hot test was carried out for a planned duration of 25 seconds at the High Altitude Test Facility of the ISRO Propulsion Complex at Mahedragiri in Tamil Nadu.

Test closely matched with predictions

"All the propulsion parameters during the test were found satisfactory and closely matched with predictions," an ISRO statement said on Monday. The cryogenic engine will be further integrated with the propellant tanks, stage structures and associated fluid lines to realise the fully-integrated flight cryogenic stage, ISRO said.


Chandrayaan-3 lander

Earlier this year, the Chandrayaan-3 lander successfully underwent EMI/EMC test at U R Rao Satellite Centre here. 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, it was noted.

"This test is a major milestone in the realisation of the satellites," ISRO had said. Chandrayaan-3 interplanetary mission has three major modules: the propulsion module, the lander module, and a rover. The mission's complexity calls for establishing radio-frequency (RF) communication links between the modules.



Chandrayaan-3 is a follow-on mission to Chandrayaan-2

During the Chandrayaan-3 lander EMI/EC test, launcher compatibility, antenna polarisation of all RF systems, standalone auto compatibility tests for orbital and powered descent mission phases, and lander and rover compatibility tests for post landing mission phase were ensured, according to ISRO. 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.

ISRO plans to launch the mission in June.

It will be launched by Launch Vehicle Mark 3 (LVM3) from the Satish Dhawan Space Centre in Sriharikota (Andhra Pradesh). The propulsion module will carry the lander and rover configuration till the 100 km lunar orbit. The propulsion module has a Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload to study the spectral and polarimetric measurements of Earth from the lunar orbit.
