According to the information of the Indian Space Research Organisation (ISRO), the flight acceptance hot test of the CE-20 cryogenic engine that will power the cryogenic upper stage of the launch vehicle for the Chandrayaan-3 mission has been successfully conducted.The Bengaluru-headquartered national space agency said 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 Mahendragiri in Tamil Nadu on February 24. In a statement by ISRO said that 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. Earlier, Chandrayaan-3 lander successfully underwent EMI/EMC test.During the Chandrayaan-3 lander EMI/EC test, Antenna Polarization of all RF systems, Launcher compatibility, Standalone auto compatibility tests for orbital and powered descent mission phases, and Lander & Rover compatibility tests for post landing mission phase were ensured. The performance of the systems was satisfactory, according to ISRO.The main components of the interplanetary Chandrayaan-3 expedition are propulsion module, lander module, and rover module. Due to the complexity of the mission, radio-frequency (RF) communication channels must be established between the modules.According to ISRO, launcher compatibility, lander and rover compatibility, everything was ensured during the Chandrayaan-3 lander EMI/EC test.Chandrayaan-3 is a follow-up mission to Chandrayaan-2 and aims to demonstrate end-to-end capability in safe landing and roaming on the lunar surface. In June, ISRO will launch the mission. Launch Vehicle Mark (LVM3) will carry out the launch from the Satish Bhawan Space Center in Sriharikota, Andhra Pradesh. Up to 100 kilometres into lunar orbit, the propulsion module will support the lander and rover configuration.All about Chandrayaan-3The Indian Space Research Organization (ISRO) has a third lunar exploration project called Chandrayaan-3. Another lunar mission to demonstrate soft landing was planned after Chandrayaan-2, where a last-minute error in the soft-landing guidance software prevented the lander from successfully soft-landing after a successful orbital insertion. Only a lander and rover identical to those used in Chandrayaan-2 will be present in Chandrayaan-3, which will be a mission repetition of Chandrayaan-2. Although it wont have an orbiter, its propulsion module will function as a satellite relaying communication. The launch of the spacecraft is planned for June 2023. According to the ISROs former Chairman K Sivan the project will cost around Rs 615 crore.Fact about Chandrayaan-3Only a lander and rover identical to those used in Chandrayaan-2 will be present in Chandrayaan-3, which will be a mission repetition of Chandrayaan-2. Although it wont have an orbiter, its propulsion module will function as a satellite relaying communication.What is Hot testA hot test is a production test used to check all the engine operating parametres as they would function in the real-time in an actual vehicle.What is EMI/EMC testTo assure the performance of the satellite subsystems in the space environment and their compatibility with the anticipated electromagnetic levels, EMI-EMC (Electro-Magnetic Interference/ Electro-Magnetic Compatibility) tests are carried out for satellite missions.The objectives of Chandrayaan-3 mission are:To demonstrate Safe and Soft Landing on Lunar SurfaceTo demonstrate Rover roving on the moon andTo conduct in-situ scientific experimentsAll about Chandrayaan -2On July 22, 2019, a GSLV Mark III-M1 launched the spacecraft on its voyage to the Moon from the second launch pad at the Satish Dhawan Space Centre in Andhra Pradesh. On August 20, 2019, the spacecraft entered the Moons orbit and started orbital positioning manoeuvres in preparation for the landing of the Vikram lander. On September 6, 2019, the lander and rover were supposed to touch down on the near side of the Moon in the south polar area. But on September 6, 2019, the lander crashed after it deviated while attempting to land.
