Actually they do put on board cameras on the rocket but never release the video for reasons best known to them.

We understand each country and even companies has a comfort level with information.

May I suggest however that someone could put some highlights into a video and place it on utube.    The world has much interest in India.  ;)

^Looks like, the booster seperation video was not shown on any of the big screens in the control room OR the TV cameraman was instructed to avoid the screen showing the seperation video.

One of the News Papers it is mentioned that there were few under performances by GSLV MK III during the test flight. Please find below the same. .
1) INTERRUPTION IN FUNCTIONING OF S200 AND L110 MOTORS
2) SEPARATION OF BOOSTERS DELAYED BY 4.5 SECONDS THAN EXPECTED
3) L110 PERFORMANCE DELAYED BY 5 SECONDS IN SECOND STAGE
4) L110 SEPARATION TOOK PLACE 15 SECONDS EARLIER THAN SCHEDULED TIME
5) C-25 DUMMY CRYO SEPARATION TOOK PLACE 8 SECONDS AFTER THE ACTUAL TIME
6) MALFUNCTION IN BECON SIGNAL OF CREW MODULE .
Also it was obvious during flight as vehicle was not following exact path that is should have been. Could these discrepancies be the reason for deviation?

This is the article in question (in Telugu). I guess the article is comparing the flight profile mentioned in brochure versus the actual profile. Does the article mention why there was a discrepancy in actual vs brochure flight profile? (My knowledge of Telugu is very limited, so couldn't find out if the article mentioned why there was discrepancy)

If we compare actual flight profile vs brochure flight profile (attached images) - we can see that actual L110 ignition was "postponed" by 5 seconds (T+120s) compared to what's mentioned in brochure (T+114.71s). Hence all the subsequent events like S200 separation, payload fairing separation, L110 shutoff, L110 separation, and CARE separation happen 5 seconds later compared to the ones in brochure. Basically, S200 boosters burned 5 seconds longer than what's mentioned in brochure.

I don't know whether or not it was intentional. I am guessing they might have thought S200 boosters have sufficient juice till T+120s and modified flight profile before launch ;D Remember them saying that they were working on getting the launcher ready till a week before launch. This is just a guess ;D

Looking at the predicted and actual time-vs-velocity and time-vs-altitude plots, we can see that they fairly match (barring some under-performance by S200 just before L110 kicked in).

Has anyone run across any high resolution photos of the launch?  I've only seen the three low-resolution images on ISRO's page, which I find surprising.

 - Ed Kyle

I checked Press Trust of India's site ptinews.com and searched archive for 'GSLV'. Thumbnail preview along with original image info(xmp,exif data) of launch photos were there, and from data it seems they are of higher resolution. But..... it looks like general public can't access those. By the way if you look at hires pre launch images on twitter you can see 'L' of 'GSLV' slightly exposed.

There is nothing to hide as the rocket is neither carrying any kind of revolutionary technology or a classified payload.They simply just don't bother to release the video to the public.

A request has been sent to ISRO top officials for their permission to release the video,lets see what happens.

I simply don't understand why ISRO is so reluctant to release video and high resolution launch images. Why not share the proud achievement even more effectively? Or is ISRO simply a govt organization that is a little too safe in its funding/importance? (Rather like ESAs Rosetta media policy)

They will probably release the video after the completion crew module analysis.

CARE crew module will be displayed in "World Space Week" exhibition at Kochi, Kerala from Oct 4 to 10:

The cup cake-shaped module was taken to a height of 126 kms and released. It landed in the Bay of Bengal from where it was recovered by the Coast Guard. After being subjected to a gamut of studies, the module was put on display at the space museum of the VSSC in Thumba.

This, however, is the first time that the module, which was developed by VSSC is being taken out of the facility for public display. The space expo will be held at Ernakulathappan grounds (next to Durbar Hall), Kochi, from October 4 to 10. It will showcase various missions of ISRO, societal applications of the Indian space programme. Former ISRO chairman K Radhakrishnan will inaugurate the expo.

Paid a visit to the ISRO's Space Expo at Kochi that began yesterday. Together with the usual mockups of satellites and engines, they had the real CARE module and a mockup of the scramjet engine. Got a few snaps of the capsule. ( Sorry for the poor quality of the pics. The lighting was less than optimal, and all I had was my phone camera.  :( Still, here we go ! )

Note: The red hue of the capsule is due to the lighting. Its more of an orange color though.
