ISRO successfully conducts key rocket engine test for Chandrayaan-3
Bengaluru (PTI): 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 was successfully conducted, according to the Indian Space Research Organisation.
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, the Bengaluru-headquartered national space agency said.
"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.
Earlier this year, 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, lander module, and a rover. The mission's complexity calls for establishing radio-frequency (RF) communication links between the modules.
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 100 km lunar orbit. The propulsion module has Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload to study the spectral and polari metric measurements of Earth from the lunar orbit.

Will follow Shinde in any direction he goes: MLA Shirsat on allying with Pawar Sr for CM post
Mumbai, Nov 21: Shiv Sena MLA Sanjay Shirsat on Thursday said his party leaders will follow Maharashtra Chief Minister Eknath Shinde in any direction he goes post-assembly poll results and decisions taken by him will be acceptable to them.
He asserted the party will solidly back Shinde, who heads the Shiv Sena, as it trusts his leadership, comments coming two days ahead of the state assembly poll results.
Asked what if Shinde goes with rival NCP (SP) president Sharad Pawar to become the chief minister for a second time, Shirsat said, "We are committed to (follow) whatever Eknath Shinde decides. We will be solidly with him. We trust him and it will always be there."
The MLA from Chhatrapati Sambhajinagar (West) was responding to the question asked on a TV channel.
Shirsat said Shinde, who took over as CM in June 2022 after revolting against the then leadership of the Shiv Sena, only goes in the "right direction" and this has been the experience of party leaders.
Shirsat was one of the Shiv Sena MLAs who sided with Shinde at the time of the revolt.
Asked about the comments of his ally, BJP leader Pravin Darekar said, "Shirsat's remarks do not reflect the official stance of the party. Eknath Shinde's party contested against Uddhav Thackeray-led Shiv Sena (UBT) and Sharad Pawar's NCP (SP). Such an alliance with the MVA was inconceivable."
The BJP, Shinde-led Shiv Sena and NCP headed by deputy CM Ajit Pawar are members of the ruling Mahayuti alliance. On the other hand, the opposition Maha Vikas Aghadi (MVA) consists of the Congress, Shiv Sena (UBT) and NCP (Sharadchandra Pawar).
Asked what if Shinde is not made the CM again if Mahayuti retains power, Shirsat said, "A decision on this will be taken only by Eknath Shinde. It's his right and we cannot even comment on it. Whatever decision Shinde takes will be acceptable to us."
Voting for the 288-member state assembly concluded on November 20 and results will be declared on November 23.
