That heat shield is humongous!! Probably it can carry two crew modules to LEO
By the way, what's that black conical structure on which crew module is mounted - is it payload adapter?

seems like an awfully big faring for it

it is a payload adapter, but looks very small for the heat shield. LVM3 is like 3 PSLVs in one rocket

Thats standard fairing for LVM3. Manned mission fairing will be different in design and may be in size. The operational spacecraft will also have a service module.

Yes, operational manned mission would have a service module, and crew escape system at the top. So, design might be different from this "cargo carrier" heat shield.

And eventually a Soyuz/Shenzhou style orbital module as well, when they plan to do docking and stuff..

Look what I found!
Everybody else's capsule has a rounded bottom, while India's crew capsule looks to have a flatter bottom. Why is that? Wouldn't a rounded bottom be safer and more stable for re-entry?

How is it not rounded? It looks just as "rounded" as the Orion and Dragon heat shield.

Maybe an error in that illustration? The actual photos (and some other recent illustrations) do show a kind of rounded bottom , isn't it?

You can see the curvature, its not flat.

From a report couple of days back
http://www.thehindubusinessline.com/news/science/isro-rushes-to-clarify-on-gslv-mk-iii-launch/article6646542.eceAt 80 km, the atmosphere takes over. From then, the engineers can only check the speed of the falling object, which they do first by firing small rockets on the module in the reverse direction, and later by opening three parachutes one after the other.
I might have missed it. I thought the capsule would be on a free fall with only the parachutes to slow it down in the later phase. Looks like there are small rockets to do the job initially.

Regarding that video from TV9 Telugu News -- they seem to be showing excerpts from an ISRO-made video in between. Does anybody have any direct link to that ISO-made video itself? This would be having the content you posted screen-snapshots of.

It would be interesting to see how its done (Dragon?). For Soyuz and shenzhou, small solid rockets are fired just before the touchdown. For ISRO, it seems liquid thrusters would be used for braking before the parachute deployment. Check out the propulsion module.

There seems to be ISRO-DECU animation describing GSLV Mk3 X1 and CARE mission, which was shown to press at SDSC SHAR. Captured some screenshots from various news sources.
By the way, what's that black conical structure on which crew module is mounted - is it payload adapter?
