The cryo stage looks like without hard casing.

It surely has a hard casing, what you see if a thermal blanket to keep the LO2 and LH2 below boiling point. This will be removed before launch.

Yup..will be removed shortly before launch.....

GSLV-D6 / GSAT-6 Update: Preparations for propellant filling of cryo stage are under progress

[sudhan]

Hoping for all "parfaarmans naarmal"

Best of luck, ISRO!

[JTull]

Is there a live broadcast?

[sudhan]

Yes, on DD for sure. Check the ISRO website. Has some info..

[Varoon Shekhar]

Yes, all the best for a successful mission, which I'm more than 50% sure will take place.

The reservations are about, whether this particular cryogenic stage underwent sufficient testing on the ground; whether they have become a little complacent about the other stages esp the liquid strap ons( unlikely, but not impossible!), whether the extra stresses created by the greater mass/weight of the satellite, 2117kg, have been totally accounted for; plus complacency about other components including control systems, stage separation systems, auxiliary propulsion, on board computers, connectors, wiring etc.

Saar, any particular reason they wouldn't have done due diligence on such a basic thing?

"Saar, any particular reason they wouldn't have done due diligence on such a basic thing?"

Sum, I guess I'm stating the obvious , it's because of past setbacks( failures,interruptions), at least 4 with regard to the GSLV. But you're right in implying that, they are more diligent now, than before. It's good, isn't it, to keep a degree of scepticism, not negativity or sour pus whining. As a cushion, almost.

Here's hoping for a spectacular success!

The poster is just experiencing a case of "thruster shiver" i think and so no need to worry. ISRO did not get to where it is now by being shoddy. Just enjoy when it gets off the ground and be assured ISRO will master the GSLV as it has PSLV.

Exactly, thanks

Singha saab ....there was one professional anti jinx member r8 ?? ..can't recall his name


duhhh..why have deleted the post ??

[member_28108]

Dilbu

[shaun]

yes yes

[member_22539]

professional anti jinx member

I guess if you hang around on the Internet long enough, you will see everything.

But truth be told, he is quite effective. Someone must get him to do his magic.

[JE Menon]

wheretffore art though Dilbu?

[Singha]

not being a professional anti-jinxer like dilbu I chose to delete my post, lest it come true and the mob here tears my entrails apart and puts my head on a stick

Link to live webcast from ISRO. It is windows media player format so works with IE. Web cast schedule Starting @ 16:22 IST

GSLV-D6 / GSAT-6 Live from Launchpad

[rahulm]

DD bilingual commentary has started. ISRO webcast yet to start.

All the best ISRO.

[rahulm]

ISRO webcast has also started.

[Patni]

Web cast is streaming now.

[rahulm]

I wish someday the commentators will learn the power of silence and that there is no need to summarise the control sequence.

The DD webcast does not have the control centre command voiceovers.

[shaun]

Hindi commentator is using sanskrit

The DD webcast does not have the control centre command voiceovers.

Maybe this is because of the strategic nature of the payload ??

[rahulm]

For Jingos, ISRO should have a raw feed from the control centre from where commentators will be always banned

[shaun]

what strategic payload have to do with commentaries

[Singha]

we still lack the soothing HD camera on the rocket to point down and show the launchpad , stage separations.....

[Singha]

3:45 to go....

[rahulm]

Unified Comms now. Hindi commentator now speaking in English but speak non stop they will.

[Singha]

2nd stage ignited....

[rahulm]

the solid motor has burnt out. The 4 liquid strap ons will now haul the empty solid motor shell
