That 2nd guy, who appeared at the mic after Nair, said that GSLV with indigenous cryo stage will be launched in a couple of months. Does he mean GSLV-Mk3?

I would also prefer the commentators to know when not to talk. We are keen to hear the announcements being made in the Control Room.

So it will be the regular GSLV-Mk1 then, but for the first time with an Indian-made cryo stage instead of a Russian-made stage?

I thought the Mk-2 was the one that failed and blew up.

Didn't we decide to then skip past that to Mk-3?

Mk1 --> GSLV with russian cryo stage (stop-gap model till Mk2 comes online. since we bought only 7 cryo stages from russia (IIRC) that is the upper limit on number of Mk1)
Mk2 --> GSLV with Indian cryo stage
Mk3 --> essentially a new rocket with all major subsystems desi with the GSLV name

the failure was in the second operational flight which was actually the 4th flight of the Mk1.

there have been no Mk2 launches so far.
AFAIK both Mk2 and Mk3 will continue in service simultaneously to cater for different launch requirements.

Congratulations once again ISRO. The PSLV and India also enter the space annals of Switzerland and Turkey.

Onward to the GSLV & GSAT4 launch.

'Major discovery' from Chandrayaan mission set to be announced

Mumbai: The Indian Space Research Organisation (ISRO) and the American National Aeronautics and Space Administration (NASA) are set to make a major announcement in the coming days related to as discovery made by one of the payloads onboard the immensely successful Chandrayaan-1 mission.

The announcement is expected at a media interaction scheduled for Thursday at NASA headquarters in Washington DC. The interaction will also feature Carle Pieters from Brown University, who was the principal investigator for NASA's Moon Minerology Mapper (M3) payload onboard the Chandrayaan.

Brown University have declined to comment about the nature of the announcement, merely saying that it would ''...be a major announcement of a major discovery...'' and would be ''...something great for Chandrayaan. It will mark a major leap for India's space programme."

The Thursday interaction has not been denied by ISRO officials.


It is being surmised that the announcement may be related to the discovery of water on the lunar surface. This was one of the main missions of the prematurely aborted Chandrayaan mission.

Does India have the means to interpret the shared data from Chandrayaan?

In terms of actual discoveries and revelations, will the partner nations still claim "first-to-discover" tag though Indians transported them all the way there?

Just trying to make sure that CY-1 would get the right place in history.. :-?

CY-1 already does. No one cares about chang'e any more. It may as well have been a camera set on timer attached to a rock.

Guess that was not very clear. Supposing US and India have the same data in hand, interpreting the data, theorizing and coming up with "major" conclusion, Who takes the credit?
a. the country which provided the equipment?
b. the country which transported it there? or
c. the country whose scientists interpret the results first?

Just for the record books and the ego of Indians :)

In that case, the credit will go to both the organizations.Now its up to the journos to interprete the same.
Whatever be the case, chandrayann 1 will always find a mention in the report/article.

PSLV is proving to be a potent weapon of mass commercialization. Antrix should better market it better.
Beside, its a confidential data to ask, but in such a commercial launch, how much can ISRO/ANTRIX earn?

^^^ Data is not confidential, ISRO carried instruments of other countries free if the data was also shared with ISRO. So ISRO should have all the data.

@ arun

I was just interested in figures, of how much ISRO can earn if in future it plans to start commercial launch services through Antrix.
If it is a profitable business model for commercialization of ISRO technology?
As, it has already been quoted in many articles before, ISRO offers the cheapest launch cost among all space ferrying nations.

ISRO is doing exactly that. The present launch was a deal between ISIS and Antrix with Arianespace's acting as the mediator.

A much needed shot in the arm specially nowadays, when the POK-II debate is so depressing.

Kudos to ISRO team! Great work - other organizations of similar strategic importance might want to take a leaf out of it.

Someone is not happy with ISRO's launch.

Alan Smith , South Africa

"No matter how many fire cracker rockets you launch China will still be ahead of your stupid space program. China's Chang'e moon rover is already ready for launch. We are the first to discover water on the moon and we shall claim ownership. The mark of an advanced nation is its manned space program. US, Russia and China have such programs NOT india. The permanent members of UN Security Council all have good programs."

What south african is doing on swiss site? Looks like a naughty post by one of swiss.

CONGRATULATIONS ISRO.

In addition to armed forces, if there is any other organization in India I'm extremely proud of is ISRO. I hope they continue the commercialization of space services cleverly. China will soon come up with their "Made In China" cheaper alternative so I hope we stay ahead with great brand, best quality, and sound PR campaign...

Challenges ahead for ISRO
Excerpts
These included launching a Geosynchronous Satellite Launch Vehicle (GSLV-D3) with an indigenous cryogenic stage from Sriharikota in December 2009 and the PSLV-C15 ahead of December. {Which means that the turnaround time for a PSLV launch is just 2 months}

The GSLV-D3’s launch would be “a landmark in indigenous technology,” Dr. Radhakrishnan said. It would put a communication satellite called GSAT-4 in orbit. The first stage of the GSLV-D3 had already moved to Sriharikota. Its indigenous cryogenic stage would undergo tests at the Liquid Propulsion Systems Centre at Mahendragiri in Tamil Nadu. Then it would be moved to Sriharikota and integrated with the other stages, and the flight would take place in December. The PSLV-C15 would put Cartosat-2B in orbit.

What cheaper alternative do the Chinese have in the works?

I'd read that GSLV-Mk3 will cut launch costs in half. How do Indian launch prices compare to Chinese ones, right now?

Chandrayaan Found Water on the Moon?

NASA Set To Announce 'Major Discovery' From Chandrayaan Mission
9/23/2009 6:21 AM ET


(RTTNews) - The National Aeronautics and Space Administration (NASA) is set to make a major announcement Thursday about a "major discovery" made by one of the payloads onboard the Chandrayaan-1 (moon) mission, reports say.

The announcement is expected at a media interaction at NASA headquarters in Washington DC. The interaction will feature well-known lunar scientist Carle Pieters from Brown University, who was the principal investigator for NASA's Moon Minerology Mapper (M3), one of the payloads on board Chandrayaan along with 11 other instruments.

The Chandrayaan craft was launched on October 22 last year and terminated on August 30 following a communication failure. One of the mission's main goals was to sniff for water on the moon's polar regions.

A spokesman for Brown University also declined comment, saying there was an embargo. "It will be a major announcement of a major discovery and is something great for Chandrayaan. It will mark a major leap for India's space program," he said.

It is being surmised that the announcement may be related to the discovery of water on the lunar surface. This was one of the main missions of the prematurely aborted Chandrayaan mission.

Earlier missions to the moon have indicated the likelihood of water existing in the form of ice trapped 18 inches beneath the surface, around the Polar Regions of the moon.

India is already preparing for a follow-on Chandrayaaan-2 mission with Russia, which will involve the landing of a rover on the lunar surface to pick up soil samples and relay data regarding its chemical composition back to earth via the Indian lunar orbiter.

There will be no more PSLV launches this year. The C-15 flight will probably take place in Jan-Feb of 2010. All the effort at present is on D3. That's the reason FLP was used for today's launch as SLP is being prepared for GSLV. The D3 flight would be the final launch of this year. It's more or less a developmental flight, since ISRO uses the 'D' letter on only developmental flights. ISRO will be looking to launch RISAT-1 and CArtosat-2B, SRE-2 within this financial year (before April 2010)
