Congrats to ISRO and the GSLV team.

Thank to Steven and Chris for coverage!

The operationalisation of India's heavier rocket Geosynchronous Satellite Launch Vehicle Mk II (GSLV-Mk II) opens up more launch service revenue opportunity, said a top official of Antrix Corporation Ltd.

"The GSLV rocket will operate in a different satellite launch segment. We are looking at various avenues to earn foreign exchange using this rocket," Rakesh said.

Adding to this, Indian Space Research Organisation (ISRO) Chairman A.S.Kiran Kumar said: "Antrix is also looking at launching small satellites in low orbits. Several small satellites can be accommodated in one GSLV."

Cryo stage video stream

Notice the two monitors from the right, in attached pics.

GSLV MkII F05 orbit insertion accuracy: perigee within 300m of targeted figure; apogee within 80km; inclination difference is 0°; argument of perigee difference 0.01°.

Cryogenic stage was realized in a record time of 24 days. Launch campaign itself was just 54 working days! Next GSLV MkII launch planned in March 2017.

Complete launch video

At 53:43 in the launch video, the altitude and velocity plots stop updating for a few seconds.

Loss of data link ?

Any reason why ISRO skipped F03 & F05 missions when there was a continuity of Russian CUS powered operational GSLV flights ?

My guess is that those mission numbers may have been associated to particular launches (i.e payloads) that were either delayed or did not materialize (INSAT 3D, GSAT 7 etc. ) owing to the three failed GSLV flights. ISRO seem to associate mission numbers to payloads well in advance, and do not reassign them if there are changes later, which is why the PSLV mission numbers are all jumbled up at the time of launch.

There is a continuous and overlapping telemetry coverage from launch till satellite injection, handled by various ground stations. In fact, Hindi commentator was explaining the same at that timeframe in the launch video. Brunei station covers from 700 seconds into the flight till 1000 seconds, and Biak station covers from ~960 seconds into the flight till ~1600 seconds. At 54:20 in the video, we can hear "Biak AOS" (acquisition of signal). So, I guess the ground trace plotter/blinker momentarily stopped during telemetry handover from one ground station to another, and not really due to loss of data link.

F03 would just be a tail number. It is not the actual serial number of the various rocket stages. You’ll find the same thing with everyone else’s rockets.

Early references point to F03 earmarked for INSAT-3D.

The last references also include mention of CUS15 and PAM upper stages. I think that it was being prepared for GLONASS?

Congrats ISRO on an impressive launch. Man, that rocket is chunky... a proud sight to see.

Thanks also to Steven, Chris, Ohsin, the rest of the gang for all the coverage here. Those still photos are amazing

is all of that falling debris ice or some type of insulation?

Insulation I think..

That would be some interesting serigraphy ISRO does, considering the "ice" is painted over with the same writings as the underlying metal

It's just insulation (most probably expanded polystyrene, but I don't know what they actually use) helping with the thermal conditioning of the solid and the hypergols. The third stage has its own permanent insulation, which makes it black.
