The title says nothing, especially given ISRO's track record. The big news is about the launch vehicle - GSLV Mk III - the most powerful rocket from ISRO.

and the one that has potential to take an Indian to the moon.

With capacity of 10 tons to LEO, 4 tons to GTO, it's somewhere between the Titan II (used for Gemini) and Titan III.

Would have to be a pretty lean moon mission.

Some really nice photos of this on the ISRO site: http://www.isro.gov.in/gslv-mk-iii-d1-gsat-19-mission/gslv-m... Also the launch video is amazing. The moment the engines ignite the whole thing is moving most likely because those are solid rocket boosters and there's no throttle up time: https://www.youtube.com/watch?v=ae6LVG0j1Pg

The lift-off start position is at 3:45.

Congratulations ISRO.. Good step in right direction.

If we compare this to current SpaceX Falcon 9 (not Falcon Heavy ) http://www.spacex.com/falcon9

Falcon 9 can deliver 8300 Kg to GTO and 22,800kg to LEO.

GSLV MK III delivers 4000 Kg to GTO and 8000KG to LEO ( http://www.isro.gov.in/launchers/gslv-mk-iii )

Mr. Musk will be delivering hell lot of stuff to space with his reusable rockets. SO, he will be very cost competitive to ISRO w.r.t launch price.

According to the technical overview, Falcon 9 can also deliver 4020 kg to Mars :)

This is a big deal for ISRO when it becomes operational. In terms of launching its own heavy communication satellites, it doesn't have to rely on the Ariane. I can see a lot of customers queuing up to Antrix to launch commercial satellites. One can hope it eats into SpaceX's lunch in the near future.

The last 2 Indian satellites launched on Ariane V fit on this new rocket (~3.2 metric tons), but, that's a medium-sized satellite. Ariane V usually launches pairs of satellites, one ~ 3mt and one ~ 6mt.

As for price, surfing the Internets I see Rs 350 to Rs400 crore as a price, which ~ $56-$64 million dollars. SpaceX's price for a "flight proven" GTO launch is supposedly $62 million less 10%, or about the same.

The ISRO is pegging the price at Rs 400 Cr which is almost identical to a Falcon 9 at $62M at current exchange rates. Falcon 9 appears to win on price/payload, but ISRO is in the ballpark, impressive.

Earlier quoted context omitted.

Wouldn't be a manned mission, but that's plenty enough for a small rover mission.

GSLV MK3 is a crucial enabling technology for future applications for ISRO. They plan to human certify it. But most importantly, it's planned to evolve into new family of launch vehicles called Unified Launch Vehicle (ULV). A new SCE-200 semi-cryogenic engine which is under development and other upgrades could enhance the payload capacity to 6 metric tons. So the ULV will eventually replace PSLV and the GSLV MK2.

As for pricing, I definitely agree SpaceX has the edge especially with their reusable rockets. But one can still hope ISRO catches up :)

Hmm this is weird. The description says "about 10 tons to Low Earth Orbit (LEO)" but the technical specification says "8000KG".
