There used to be so much trolling by Paki's and Cheeni's whenever one of our rockets failed. Now they don't turn up so much.
But loving the hyper reaction here because someone "dared" to suggest that GSLV may be upgraded to LM5 =))
His tiny brain overheated and Collapsed at the very suggestion of the possibility :pound:

I smell pork burning as we didn't messup like the CCP did with their LM rocket killing many of their ctizens and destroying an entire village... oops, I let the secret out


Suupaa powaaa Chinese covered it up as usual :pound:

Where was that rocket going?? I think Chinese were confused between space rocket and ballistic missile.. which eventually killed their own people.. I guess they wanted to attack US with that rocket by showing that as space rocket.. :hehe: such a barbaric communist regime..:crazy::crazy::sad::tsk:

Thats the difference. Everyone wants to be perfect. But, they try to show off as if they are born with that trait.
Since when did they actually show their launches live? Or even onboard cameras?
But once they get some mastery (any which way), their condescending comments reek of arrogance.
I think one of the reasons they hate our guts is that we are not ashamed of our failures (well I hate that our idiots celebrate mediocre performance too... but thats a different topic).

Just my observation....Why do all our boosters and rockets have higher thrust than the Chinese rockets and yet the Chinese have the capability to launch greater weights into GTO?
@AnantS has already replied and provided the link for that. To make things short and in layman term, it is not simply about amount of thrust. It also depends on the duration that amount of thrust works.

I have always maintained that the obnoxiously arrogant and thin skinned wailing-for-their-mommies of the Chicom 50-cents-per-post battalion is a symptom of the one child policy. Having been babied since birth as the only child, these maa ka laadlas get unhinged at the merest suggestion that they might not be the bestest twinkle eyed boy on the planet. (Not to mean all children grow up to be that way)

BTW, LM-5 is a 879 tons rocket with GTO ability : 14 tons.'

so called is another laughable BS...

GSLV mk3 weights 640 tones , 4 tons GTO... in the future ,if the SC-160 replaces the L-110, the new varient might weight around 700 tons, with 6 Tons GTO payload. .. in LM-2/3 LV family , the LM-3C can eject 3.8 tons to GTO with 345 tons mass only...
Lol, looks like the Takleef for Chinis have started.

Just tell me, is there any kind of tax on LVs, depending upon their launch mass?

How does it matter if ISRO's 6 ton class launcher weighs 700 tonnes, if the launch cost is less than $50 million? So much for BSing about 'efficiency'. Should we go for the efficiency in the Delta IV way, ending up with a launch cost of $400 million?

Indian launchers weigh more due to the use of large solid boosters & we don't give an F, because SRBs are cheap, provide lots of thrust & we can manufacture some of the world's largest SRBs.

The launch cost of the 4 tonne class LVM 3 will be less than $40 billion. Now go compare to any other launcher, per kg.

ISRO's Fat Boy to carry global satellites only in 2020
Raghu Krishnan & T E Narasimhan | Bengaluru/ Chennai Jun 07, 2017 01:49 AM IST
ISRO's heaviest rocket GSLV Mk-III, carrying communication satellite GSAT-19, takes off from Satish Dhawan Space Centre in Sriharikota (Photo: PTI)
The Indian Space Research Organisation (ISRO) may have to wait till 2020 to hurl satellites for global customers on its most powerful rocket, as the Geosynchronous Satellite Launch Vehicle (GSLV-MK III), needs to first fulfil local demand for heavy satellite launches.
GSLV-MK III, which uses a homegrown cryogenic engine has to do at least two more launches before it begins with commercial operations. After that, Isro will need to carry heavier communication satellites to meet the shortage of transponders for Indian customers."
"It should take 3-4 years for us to get into the global market with GSLV-MK III,"says Ajey Lele, senior fellow in the Institute for Defence Studies and Analyses (IDSA). "Like the Polar Satellite Launch Vehicle (PSLV), until we conduct three to four successful launches in 4-6 tonne class of satellites, it will not attract global customers," adds Lele.
Monday's launch demonstrated Isro's mastery of a cryogenic engine after almost three decades of sustained efforts, following which the research organisation can improvise and build more powerful rockets. GSLV-MK III can carry up to four tonnes of communication satellites into space. The second development flight is slated by March.
At the same time, Isro is working on a more powerful GSLV-MK III, which can carry satellites weighinng up to six tonnes into space. Simultaneously, it will build a two-stage rocket that will be powered by a semi-cryogenic engine in the first stage and a cryogenic engine with a capacity to lift ten-tonne satellites in the second stage. Agency plans to develop the rocket by incurring a fraction of the cost that they usually end up paying for foreign launchers.
Space consultancy Euroconsult anticipates the launch of 560 satellites over a period of ten years by various companies. Most of these satellites would replace communications systems meandering in the orbit.
Over two-thirds of the commercial space market remains concentrated in the geostationary orbit- the destination for almost 300 satellites that are operated by around 30 companies for providing communications and broadcasting services. The 11 commercial constellations to be launched into the non-geostationary orbits for the twin purposes of communications and satellite imaging should represent a market of $1.6 billion per year over the decade, it said.
Analysts say that the opportunity for Isro will only increase as it perfects a safer and more reliable rocket.
"The market is expanding for many clients for this class of rockets. India, under all circumstances, will offer a cost advantage," says Lele.
ISRO will, however, use an Ariane 5 rocket, provided by the European launch provider Arianespace, to hurl the GSAT-11 satellite in its upcoming launch.
ISRO's chairman, A S Kiran Kumar, had on Monday said that the organisation's focus would be to reduce reliance on foreign launchers to carry satellites to space.

it's too funny watching some idiot 'talking BS' so Seriously... LOL...

------------------------------------
but, dear...you have watched the live broadcast of the launch and you can find the record on youtube. more importantly , such question has been discussed a few pages back...

the time line of the GSLV mk3 Launch...
View attachment 16517

well explained even earlier in ISRO official brochure...



GSLV mk3 is a three stage LV...the S200 booster is actually the first stage, the L110 stage ignited at 114.9S when already in the air ,and both solid and liquid engines worked Together for another 26 seconds. basicly the thrust solid rocket engine is not adjustable, so near the end of burning period of S200, the thrust might declined and the Liquid engine joined in the show not only for the compensation for declining thrust but also helping adjusting the total thrust flexibly as the designed thrust curve request...

-------------

BTW, LM-5 is a 879 tons rocket with GTO ability : 14 tons.'

so called is another laughable BS...

GSLV mk3 weights 640 tones , 4 tons GTO... in the future ,if the SC-160 replaces the L-110, the new varient might weight around 700 tons, with 6 Tons GTO payload. .. in LM-2/3 LV family , the LM-3C can eject 3.8 tons to GTO with 345 tons mass only...

actually the hope for better efficiency of future indian LV is not on the S200/S250 solid rocket booster but something like the "Common Booster Cores " tech on Delta IV Heavy.. of course with Liquid rocket engine stages



again...on the PPT (from BR)...lol...
GTO 16.3 tons....wow....but it seems to be a 1200+ tons Giant


Video link? I want to know what he said

India to get another ‘eye in the sky’ by month-end


NEW DELHI: After the historic lift-off of India's heaviest rocket GSLV-Mk III, Indian Space Research Organisation (Isro) is gearing up to launch a Cartosat-series satellite, also called the 'eye in the sky' because of its surveillance capabilities, into the 505-km polar sun synchronous orbit by then end of this month.

The 550kg satellite, the fourth of the Cartosat-2 series, is to be launched by the PSLV-C38 rocket. The Cartosat-series satellite is an advanced remote sensing satellite capable of providing scene-specific spot imagery. It carries a state-of-the-art panchromatic (PAN) camera that takes black and white pictures of the earth in the visible region of the electromagnetic spectrum. The swath covered by this highresolution PAN camera is 9.6 km and their spatial resolution is less than 1 metre. The satellite, which can be steered up to 45 degrees along as well as across the track, covers the entire globe in 1867 orbits on a 126-day cycle.
The Cartosat-2C series satellite has added teeth to India's military surveillance and reconnaissance capabilities, and has been providing high-resolution images of 0.65 metres, an improvement over the 0.8m resolution of the earlier missions. The first major use of the Cartosat-2C satellite by the military was when the Army counted on satellite images to hit terror launch pads across LoC during the surgical strike in 2016.

The imagery of Cartosat satellite is significantly used for cartographic applications, urban and rural applications, coastal land use and regulation, utility management like road network monitoring, water distribution, creation of land use maps, precision study, change detection to bring out geographical and manmade features and various other land information system (LIS) and geographical information system (GIS) applications. "Demand of Cartosat images has increased in recent years as most departments of the Union government are relying on satellite images to get accurate data about a geographical area to implement their development projects," says an Isro source.

Cartosat-2C, whose panchromatic camera covers 50% of the payload area and is made at Ahmedabad-based Space Applications Centre, is the best-in-class remote sensing satellite that can not only click pictures of areas of interest, but also record videos of sensitive targets from space, compress it, and relay it back to earth. The satellite can produce images of up to 100 cm in resolution (black and white only), compared to the 80 cm offered by Ikonos, operated by America's DigitalGlobe, which is multispectral.

Can somebody explain me why isro is better than other indian R/D establishment:confused1:
If we manage to replicate the efficiency of ISRO with other organisation then it would be mashallah :india2:

Or ya da know even a li'l about other organizations?

Making a single use rocket engine is way easier job than making an eventually ignited turbofan. Thermal Creep is a great issue.

Similarly with other cases, other PSUs have to do even more difficult jobs than ISRO in many cases. Also, ISRO isn't successful or anywhere near schedule either. We were supposed to have GSLV Mk3 10 years ago.

Everyone has success & failures.
