ISRO - General Discussions

And the unfortunate part is, the G-1 vehicle was fully assembled at SH, and there were reports that the crew module had arrived. The launch campaign was announced. Some major issue must have been detected, for news of G-1 to vanish.

No G1 wasn't fully assembled, they only started integration of S200 boosters for PR. There were no reports of CM at SDSC, In Jan End ,it was sent to VSSC from LPSC after integration of its propulsion system, Crew Module is still at VSSC as per news reports

Does it mean SCE-200 is ready for flight?

Or still it needs few years of testing.

Damn man, this is frustrating with ISRO due to continuous delays in some critical projects. They are trying and I can hope for the best.

PHTA version of the engine doesn't have main thrust chamber, it only has preburner, Turbopumps, and injector head, hence it is called Power Head Test Article(PHTA), but still a very important milestone, this has proved the metallurgy,design & manufacturing of the Turbopumps ( they should work in oxygen rich & hot environment) , Preburner & most importantly it's ignition sequence, this is a very important test, upcoming version of engine will be a fully integrated engine which means it will have thrust chamber as well

So if everything goes well from now, we can expect the engine by next 2 years

There should at least be more PSLV flights, particularly since they were scheduled. Is it because, as IndxTechStyle says, the satellites are not ready?

My college final year technical presentation was on plasma engines . I made most of my presentation based on internet text and images of the amreeki vasimir engine . To think enginiggers in training can now copy paste ISRO content brings a smile to my face.

Not just this, LPSC is also doing R&D of RDE, Tripropellant engines as well

Delays in the Gaganyaan project are totally understandable. But why are there no PSLV launches so far this year. A few of them are overdue. Is it because the spaceport is now occupied by 2 GSLV( NISAR and Bluebird, Mk 2 and 3 respectively) vehicles, and those have to be launched before another PSLV goes up?
