First Look: India's Heaviest Launch Vehicle GSLV Mk.III with Unmanned Crew Module Onboard Rolled Out

This is mere a test flight that may or may not lead to the final product many a year down the road。

Heck，even the test hasn't started，let alone the result known。

And you are already celebrating？

What‘s there to shout about such a large rocket that can only do puny 4 tons GTO and 10 tons LEO，respectively？

Enlighten me pls？

................shoooo.......

A very important point ..... @Guynextdoor2

yeah that's a point. There are two Vikas engines there, difficult to strap on anything there.

Only in single engine configuration , 4 strap on boosters is possible !

Let alone other changes needed for heavier payloads ...

I agree you can' strap more boosters. that raises a curious question- 2 vikas engines (I think stage 2 engines in PSLV etc.) are quite strange- almost as if they're just doing the best with what they have. What if they replace this with a single stage engine later (a new semi-cryo or something)?

Possible ...

Good luck to my Indian friends. Wishing you all a successful launch.

Mm mm so are u implying that India is more advanced than Russia is rocket engine technology.

Why not? Its possible for a student to surpass their master.

ISRO to launch GSLV-MarkIII on Dec 18
December 13, 2014 01:07 IST

Indian Space agency Indian Space Research Organisation would launch the Geo-synchronous Satellite Launch Vehicle-Mark III (LVM3 X mission) on December 18 which would carry active solid boosters, liquid core stage and a passive cryo-stage.
Moving ahead with its launch of crew module recovery experiment, the ISRO had earlier said it would launch the heaviest rocket GSLV-MarkIII sometime between December 15 and 20 from the Satish Dhawan Space Centre at Sriharikota in Andhra Pradesh.
"ISRO's LVM 3 X flight planned on December 18 will carry active Solid boosters, Liquid core stage and a passive Cryo stage," ISRO said in micro-blogging site Twitter.
"#ISROLVM3 mission would validate its atmospheric ascent, esp. the aerodynamic & control features that cannot be decisively tested on ground," it said.
"#ISROLVM3 flight will carry the CARE (Crew-module Atmospheric Re-entry Experiment) Module, to be recovered from the Bay of Bengal," it said.
According to Satish Dhawan Space Centre Director, M Y S Prasad, the launch intends to test the atmospheric characteristics and stability of the updated rocket on its way up and would study the crew module on its re-entry into the atmosphere.
While the rocket would cost Rs 140 crore, the crew module would cost Rs 15 crore.

Cyrogenic engines use Liquid Hydrogen in place of Kerosene used by the Semi-Cyros. While cyrogenic engines are more efficient as compared to semi's (google specific impulse) and therefore can theoretically haul more weight, they are much more costly and much more technically challenging to make (esp. with increasing size) which is why Russians went to cyrogenics only after 1980's and used semi's before. ISRO should have also followed a similar path; but no, these idiots are probably like Kennedy in the 1960's - we are going there (moon) not because its easy but because its hard. LOL
Oh and your query, if we want to become a big playa in this industry, we MUST make BIG racket. 2000Kn is just the beginning. Others have much bigger ones

Very insightful/ valuable post. Nice one.

It's possible. But India is not there yet.

You calling Kennedy as idiot? Lol.

We are not there yet, thats why it is possible. After reaching, there is no question of possibility or not.

Now when will UK rise up and face the USA

Dude they are different tech. Cryo is more powerful but more complex because of collant systems. The americans used it because they needed the thrust for Apollo with 5 engines. The Russians used 30 non cryos for their moon rocket (N 1), the damn thing never made a single flight. Semi cryos are less complex so for lower thrust rockets Russians used those plentifully- they also developed unique design and tooling to create efficient machines. You need to look at both in perspective- both have their uses.

I know bro the whole history of cryo and semi-cryo. And how the N1 failed against the more complex Von Braun's Saturn V.

BTW, did anybody realized the space program of JAXA?

So once India has a successful launch, India will catch up to America in space tech, of 1965. Almost 50 years behind, just 49.

Are you kid? 50 yrs behind? Rocket science is not just about rocket fuel bro.

You don't know much about engineering or economy or anything for that matter. Don't waste those little gray cells, you won't get this.

German tech ... if you want to be more clear !
