Chennai: Isro to undertake the heaviest launch in December with GSLV Mk-III rocket which will carry 3.2-tonne GSAT-19E communication satellite from Sathish Dhawan Space Centre in Sriharikota.

While speaking at the golden jubilee celebrations of Madras Institute of Technology Alumni Association in Chennai on Friday Isro Chairman A.S. Kiran Kumar said the GSLV Mk-III rocket’s flight hardware is getting assembled for the launch.

GSAT-19E
· Payload for the first developmental flight of GSLV MK-III
· Experimental satellite to act as test bed for several new technologies like unified modular bus, deployable thermal radiators, electrical propulsion, indigenous Li-Ion batteries and C-band TWTAs, optical payload, etc.

Quote
GSAT-19
GSAT-19 is planned as the payload for the first developmental flight of the indigenous GSLV-Mk III-D1 Launcher. The satellite is planned to carry Ka and Ku band payload along with a Geostationary Radiation Spectrometer (GRASP) payload to monitor and study the nature of the charged particles and influence of space radiation on spacecraft and electronic components.

GSAT-19 satellite will employ advanced spacecraft technologies including bus subsystem experiments in Electrical propulsion System, indigenous Li ion battery, indigenous Bus bars for power distribution, etc.

The target is still December even now when we are only a few months away. Good going!

Now this report of timesofindia is saying that the first development test of LVM3 will happen by next year.

Quote

Simultaneously, an advanced cryogenic engine double the capacity with higher thrust is planned for the GSLV-Mk III launch by next year, Liquid Propulsion Systems Centre (LPSC) scientists said.

There is no news on stage testing for the Cryogenic stage (engine testing is done). If the stage testing is still pending, the target date of Dec16, looks unrealistic to me.

Agree. The launch could very well slip to early next year. But back in 2012 when they had LVM3-D1 marked for a 2017 launch in their reports, I was sceptical and expected it to be delayed further by years. That they have been able to stick to their schedule comes as a pleasant surprise to me. It might owe a lot to the confidence that success of CUS and LVM3-X has given them.

According to the following report, CE20 cryogenic stage testing seems to have started, even though it unambiguouslay didn't refer to the stage testing.

Stating that GSLV Mk-III cryogenic engine testing had already started, Rakesh said, "We are planning to complete engine readiness in about two months time."

The target launch date was December 2016 but there could be slight delay as large number of tests have to be carried out.

I got a chance to visit SDSC last week & the feedback I got during the visit was that it is unlikely that the launch will happen this year. Might get pushed to early 2017.

Great! Were you able to visit any of the launch pads?

I too feel that ISRO is just keeping December as an optimistic target. Its a development flight anyways, and there might be a lot of tests that they need to do.

Btw, did you hear any updates about the status of C-25 stage testing for LVM3?

Yes, I got visit both the launch pads, but since PSLV launch was scheduled we could not go close to FLP. However, I got to see the SLP closely it was very exciting :)

No update on the C-25 though sorry.

ISRO gears up for launch of 3.3-tonne payload
Quote
The target is to put into orbit GSAT-19E, an indigenous communication satellite that will weigh about 3.3 tonnes, the heaviest payload to be launched from the Indian spaceport.
Quote
However, it will be just a few notches lighter than GSAT-18 (3.5 tonnes) that was sent into space by the European Space Agency from French Guiana on Thursday.
“The satellite assembly and launching process of the GSLV Mk-III are in advanced stages. We are confident that SDSC will make yet another mark among the space-faring nations,” said SDSC Deputy Director M. Badarinarayana Murthy.

Alpha Titanium Alloy is one of the difficult to forge materials due to its high flow stress coupled with tendency of cracking. With modified processing parameters and design innovation, the problem was eliminated. Due to this effort, direct pay load gain advantage is achieved. Thus more Transponders can be loaded in satellite,” said P.K. Mansoor, Senior Manager, Steel and Industrial Forgings Limited (SIFL).

The ISRO, he said, planned to achieve this capability in a couple of years. The stage test of semi-cryogenic engine for the GSLV-Mark III would be flight-tested in December.

I guess he meant the CE-20, not SCE-200.

LMV3, a full-fledged vehicle will be launched in the first half of 2017. Mr. Rao said the heavy launch capability launcher would enable ISRO’s self-reliance in launching of satellites. It will send four tonne class geosynchronous satellites into the orbit.
