L-40's have been filed with UH -25 (2150 IST).
The second stage GS-2 (whose predecessor leaked) was filled by 1800 IST - after prep commenced at 1148 IST. (N2O4 completed by 1423 IST, UH25 started at 1618 IST)Seems a bit odd - a) given that it's so early, and that the last time round, they did the tanking ~7 hrs prior to launch IIRC b) It's taken ~6 hours to fill the second stage. I guess they deliberately slowed it up, and had leak checks periodically.


Can anyone here confirms that all the photos and videos currently on the ISRO website are from the second launch attempt and not from the one last August? Thanks!


The ones in my post earlier are all from the January campaign, as are the pictures posted today... (It's a guess...given that these photos weren't posted for the previous launch campaign).

Sure, it may not be paint, and it may just be the colour of the insulation material, but what good insulators are coloured black?
It is not a black paint but I guess its a "Multilayer Insulation blanket" wrapped manually. It came in all colors.

It strikes me now that quite a few of the shuttle's tiles were great insulators and they were black too. Do we know what insulating material they're using for the cryo-stage? Some carbon composite?

Thanks for the coverage, but in summary, was this vehicle leaking and they rolled back, fixed and rolled back out again? That was the interim delay?

Did they replace the booster or just repair it?

The stage that leaked was replaced with a new one made from an alloy less susceptible to cracking; the first stage is also new, and the boosters were refurbished.

And a reminder, we're going with this thread for this next attempt. A link to the first live coverage post will be added to the opening post.

L-40 N2O4 filling completed as of 2344 IST last night.

Preparations on for Cryo stage filling.


LOX filling commenced @ ~1147 IST

GSLV getting ready !!

That is a fantastic shot.

Interesting. A similar pic in the brochure has a white panel hosting the ISRO logo, so I guess they have changed it. Source/details?


Also, looking at the EOC-EIRP diagrams for the Ku and the Extended C band transponders - does anyone know how the perimeter has come to be defined by straight edges for these two sets (6 transponders each)? The Ka band (going to be used for attenuation studies, 2 operating frequencies, one transponder each I think) zones of coverage are delineated by a more intuitive ~circle..


Btw, here's a shot of the cryo-stage mounted in the diffuser at the LPSC Mahendragiri High Altitude Test Facility : https://twitter.com/ISROOFFICIAL/status/419135493884768256

Webcast is showing live images from mission control and of the pad but keeps cutting back to the bluescreen intermittently.

The ISRO Webcast, while lower video quality has English commentary along side the Indian for those wondering what is being talked about.
