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.....

Hoping for all "parfaarmans naarmal"

Best of luck, ISRO!

Is there a live broadcast?

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

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.

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.

All the best ISRO.

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.

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

rahulm · Post by **rahulm** » 27 Aug 2015 15:47

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