Isro will break history again in few months , when they launch 83 satellites in 1 rocket breaking the Russian record .


Can't wait to see all the red faces, especially bbc.

OK.. so it was launched earlier...........then why the engine test again ?/ more powerful one ??

In its first flight it went only with two functional stages , the cryogenic stage was a dummy.

103 Satellites now.

We have At least 7 launches this year.
4 PSLV + 2 GSLV MK2 + 1 GSLV MK3.

Great news. But don't forget to open up a new thread for attaching the booster to the rocket. Maybe a new thread for screwing in the first screw,

One more step towards manned space mission!

Manned space flight is so easy. India can easily do it. It choose to do more difficult missions.

Great...we can have heavy lifts this year... waiting for GSLV MKIII launch

LOL This is no heavy left vehicle. All the major spacefare nations have this capability for decades. I guess India can now be counted as a major spacefare nation.

But Taiwan does not have this capabality.............oh i forgot its not a country yet.......so you are a stateless... dont forget to open up a thread when taiwan gets country status from China.......it a shame everyone call it " chinese taipei"..LOL

He's not from Taiwan.

He's a false flagger. And you know citizens of which country burn the most with India's technological achievements.

What is the point here?

We need to recognise you started burning and you need burnool?

I'm from Taiwan. I'm not Pakistani. And it's not only Pakistani who think India brag too much.

Congratulations

Totally false flagger, he left his country in shame and now calling any country as his home. dont feed him, he will die of starvation.
And @faithfulguy im from India (Bharat)

MK III will be equipped with semi cryo in next couple of years taking its capacity to 6.5 tons which will be more than enough for all practical purposes.

ISRO Successfully Tests C25 Cryogenic Upper Stage of GSLV MkIII

​

Indian Space Research Organisation (ISRO) successfully ground tested its indigenously developed Cryogenic Upper Stage for GSLV MkIII on January 25, 2017. The cryogenic stage designated as C25 was tested for a duration of 50 seconds at ISRO Propulsion Complex (IPRC) in Mahendragiri demonstrating all the stage operations. The performance of the Stage during the test was as predicted. This is the first test in a series of two tests. The next test is planned for flight duration of 640 seconds.

The 50 second test is a significant milestone in the development of indigenous cryogenic propulsion technology. The successful hot test of the stage in the first attempt itself demonstrates ISRO’s ability to work in new areas like cryogenic technology.

The development of C25 cryogenic stage began with the approval of GSLV MKIII, the next generation launch vehicle of ISRO, capable of launching 4 ton class spacecraft in Geosynchronous Transfer Orbit (GTO). The vehicle consists of two solid strap-on motors (S200), one earth storable liquid core stage (L110) and the cryogenic stage upper stage (C25).

The C25 stage was conceptualised, designed and realised by Liquid Propulsion Systems Centre (LPSC), ISRO’s lead Centre for Propulsion, with support from various System Development Agencies from other three Centres of ISRO – Vikram Sarabhai Space Centre (VSSC), ISRO Propulsion Complex (IPRC) and Sathish Dhawan Space Centre (SDSC) SHAR. The fabrication of various sub-systems of the engine and the stage was carried out through Indian Industries.

The C25 stage is the most powerful upper stage developed by ISRO and uses Liquid Oxygen (LOX) and Liquid Hydrogen (LH2) propellant combination. The stage carries 27.8 tons of propellants loaded in two independent tanks.

Development of a cryogenic stage has unique design challenges, with liquid Hydrogen stored at -253 deg C and liquid Oxygen stored at -195 deg C in its tanks. To store these cryogenic fluids, special multi-layer insulation is provided for the tanks and other structures.

The first flight stage for GSLV MkIII-D1 mission is in advanced stage of realisation. The flight engine has been successfully tested in the High Altitude Test (HAT) facility and integrated with the flight stage.

I thought they did it last year? @gslv @gslvMKIII?

 

[Chanakyaa]

OK.. so it was launched earlier...........then why the engine test again ?/ more powerful one ??

No. At this launch the Cryo Stage was passive ( It was a dummy., Cryo Engine Not Included at all ) . It was an Important flight to test the aerodynamic parameters.
Now that the ground tests are over we will see the complete vehicle being tested.

I thought they did it last year? @gslv @gslvMKIII?

They Did. But without Cryo Engine.

I'm from Taiwan. I'm not Pakistani. And it's not only Pakistani who think India brag too much.

You see in order to increase the "Disputes" which is DIRECTLY PROPORTIONAL to the Number of Page Loads ( read reactions ) and the Adsense Impressions, Your Present is quite Justified.
I know what you are doing.

I love my country. These are the few moments in our life which makes us proud as an Indian. Eagerly waiting for whole mission to succeed and India to become major player in satellite launch technology.
