Fellas this time we are landing on mars, well not just Rover, reportedly we are also deploying mars helicopter which will hover over martian surface.

ISRO should just send a terminally ill Pajeet to Mars so we can claim first human on Mars.

All major projects have been approved now
>Chandrayan 4
>Chandrayan 5
I think CY-5 is Lupex project (Indo-Japan) where we are mostly helping with the landing of the craft.
CY-4 is sample return mission - it will have two launches.
MLM is cool will have to see the details desu.
NGLV - next generation launch vehicle project / engine development has been approved.
Also, new launch base for smart satellite launchers at kulshekkarapattanam (check spelling please) in TN is under progress - expect a completion by 2026/27.

ISRO has successfully tested the SCE200 Power Head Test Article (PHTA). There will be few more tests followed by test of full integrated engine with thrust chamber too.
Interesting that you could see greenish hue in the color - similar to early raptor 2 tests. Raptor is meant to be reused so they don't use ablative cooling as for as i know, but ig SCE200 uses.
Eventually ig they will tweak maybe.

Article content.
>ISRO is achieving progress in the design &development of a Semicryogenic engine or Liquid Oxygen / Kerosene enginewith a high thrust of 2000 kNthat will power the Semicryogenic booster stage of the LVM3 launch vehicle. The first major breakthrough in the Semicryogenic engine development programme was achieved on March 28, 2025, when the first successful hot test of Engine Power Head Test Article (PHTA),was carried out at ISRO Propulsion Complex, Mahendragiri, Tamil Nadu.
>The Liquid Propulsion Systems Centre (LPSC) of ISRO is developing the Semi cryogenic propulsion Engine and Stage. The stage (SC120) powered by the 2000kN semi-cryogenic engine (SE2000) will replace the present core liquid stage (L110) of LVM3 for payload enhancement and power the booster stages of future launch vehicles
> Non toxic and non hazardous propellants (Liquid Oxygen and Kerosene) are employed in Semi cryogenic propulsion and this will deliver higher performance compared to existing L110 stage. Induction of Semi cryogenic propulsion system along with uprated cryogenic stage in the LVM3 vehicle enhances its payload capability from 4 tonne to 5 tonne in GTO.
>Major subsystems of SE-2000 engine include thrust chamber, pre-burner, turbo pump system, control components and start up system.
>The SE2000 engine works with a complex oxidizer rich staged combustion cycle with high chamber pressure of 180 bar (with propellant feed system delivering pressures up to 600 bar) & specific impulse of 335s.
>The complex Semicryogenic Integrated Engine Test facility (SIET) was established at ISRO Propulsion Research Complex (IPRC), Mahendragiri for testing the engine and stage and was dedicated to the nation by the Honourable Prime Minister, Shri Narendra Modi, on February 27, 2024.
>This facility caters to storage and servicing of large volume of propellants and service fluids at high pressures. The capability of the test stand is validated through several flow and ignition trials. The test stand which involves many sophisticated control components are managed from a Test Control Centre that is also developed indigenously. This facility with a state-of-art PLC-based control system and data acquisition system is capable of testing semi-cryogenic engines up to 2600 kN thrust.
>Prior to the conduct of integrated engine level hot tests, it is planned to carry out performance evaluation tests of the intermediate configuration, designated as Power Head Test Article (PHTA),that comprises all the engine systems except the thrust chamber. The hot test that was carried out today, is the first of a series of tests planned to validate the design of the propellant feed system, including the low-pressure and high-pressure turbo-pumps, the pre-burner, start system and control components. All subsystems for the test were realized and had undergone rigorous qualification test prior to integration to Power Head Test Article.
>The Ignition sequence for PHTA was derived from a series of hot tests in single element level. In order to ensure the smooth ignition process during the PHTA test, another test article, Pre-burner Ignition Test Article (PITA), was realized, whichconsists of the pre-burner along with its feed systems, start-systems, and related control components. A series of tests were successfully completed using the PITA and the optimum start sequence for power head test article was derived.
>Today’s test demonstrated the smooth ignition and boost strap mode operation of engine over a test duration of 2.5 seconds. The objective of the test was to validate the integrated performance of the critical subsystems such as the pre-burner, turbo pumps, start system and control components by carrying out a hot-firing for a short-duration of 2.5 seconds. The test proceeded as predicted and all the engine parameters were as expected.
>With this breakthrough, ISRO is further planning a series of tests on the PHTA to further validate and finetune the performance before the realization of the fully integrated engine.

Point of this is that - raptor is not meant to have that. It means the cooling system were pushed to the limit leading to the metal erosion due to extreme heat. It was during early tests.
Color is specifically due to coper compounds.
