According to the Indian Space Research Organization, the flight acceptance hot test of the CE-20 cryogenic engine, which will power the cryogenic upper stage of the launch vehicle for the Chandrayaan-3 mission, was successful.

Details of the rocket engine tested in Chandrayaan-3
According to the national space agency with its headquarters in Bengaluru, the hot test was carried out on February 24 for a planned duration of 25 seconds at the High Altitude Test Facility of the ISRO Propulsion Complex at Mahendragiri in Tamil Nadu.An ISRO statement stated on Monday that “all the propulsion parameters during the test were found satisfactory and closely matched predictions.”According to ISRO, the fully-integrated flight cryogenic stage will be realized by further integrating the cryogenic engine with the propellant tanks, stage structures, and fluid lines that are associated with them.
The Chandrayaan-3 lander passed the EMI/EMC test at the U R Rao Satellite Centre earlier this year.It was noted that satellite missions undergo an EMI-EMC (Electro-Magnetic Interference/Electro-Magnetic Compatibility) test to guarantee the functionality of the satellite subsystems in the space environment and their compatibility with the anticipated electromagnetic levels. ISRO had stated, “This test is a major milestone in the realization of the satellites.
“There are three major modules in the interplanetary mission Chandrayaan-3: the lander module, propulsion module, and rover. The complexity of the mission necessitates the establishment of radio-frequency (RF) communication links among the modules.According to ISRO, launcher compatibility, antenna polarization of all RF systems, standalone auto compatibility tests for the orbital and powered descent phases of the mission, and lander and rover compatibility tests for the post landing phase were all ensured during the Chandrayaan-3 lander EMI/EC test.
The purpose of Chandrayaan-3, which is a continuation of Chandrayaan-2, is to demonstrate complete capability for a secure landing and roving on the lunar surface. The mission is expected to be launched in June by ISRO.The propulsion module will carry the lander and rover configuration up to a 100-kilometer lunar orbit from the Satish Dhawan Space Centre in Sriharikota (Andhra Pradesh). The Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload in the propulsion module is used to investigate Earth’s spectral and polarimetric measurements from the lunar orbit.
