GSLV-D5 launch fixed for 4.50 pm on August 19

In a crucial launch, India’s GSLV-D5, powered by indigenouscryogenic upper stage and carrying communication satellite GSAT-14, is set for lift off at 4.50 pm on August 19 from the spaceport of Sriharikota.

The launch time had been fixed at 4.50 pm for the Geosynchronous Satellite Launch Vehicle (GSLV) D-5 from the the second launch pad of the Satish Dhawan Space Centre in Sriharikota, about 90 km from here in Andhra Pradesh, ISRO spokesperson B R Guruprasad told PTI today.

This will be the second attempt by the Indian Space Research Organisation (ISRO) to flight test the indigenous cryogenic stage after the failure of the previous mission of GSLV-D3 on April 15. The next GSLV flight with a Russian cryogenic stage also failed in December 2010.

The vehicle had been moved to the launch pad and other preparations were underway, ISRO sources said.

After the unsuccessful launch in April 2010, the failure analysis committee had concluded that the thrust build up did not progress as expected due to non-availability of liquid hydrogen supply to the thrust chamber of the main engine.

This failure was attributed to the anomalous stopping of Fuel Booster Turbo Pump (FBTP).

In the last three years, ISRO conducted extensive failure analysis studies and reviews. Cryo stage FBTP was modified as per GSLV-D3 failure analysis committee recommendations and qualification tests carried out.

Best of Luck to ISRO.

I won't attach too much significance to the success or failure of what is still an experimental test.

What is really important is that they have all the diagnostic sensors in place .. giving really deep detailed information on the health of the vehicle.

Essentially, there is no point in a "chance" success... we need a proven, reliable vehicle which provides near certain repeatble successes (just as what PSLV has achieved).

They could have also tried a low-cost satellite as payload .... or get another space aspirant such as Brazil or south korea to try out their attempts .. just as Ariane launched India's first payload (Aryabhatta) in 1976 for free, when they were in the experimental mode of Ariane launch vehicles.

Off course, best case is that the test launch gives textbook launch and all flight information matches the expected values.

It will, in any case need, a few repeat successes, which repeat textbook launches before domestic cryo engine can be declared operational.

No point keeping "fingers crossed" ... .this ain't a cricket match. The success has to be rooted deep into the immutable laws of physics. Only then we will gain reliability and repeatability.

I appreciate that you took the pain to write all this

But still *Fingers Crossed*

Every one of us waiting for this movement from years ....





Best of luck

WE WILL SUCCEED !!!

You have fingers crossed, I have the jitters with anxiety. Hope this one is successful.

All the best India ISRO

OK so here is the Final Configuration of GSLV-D5 for you....

 

[Indo-guy]

It's the most awaited ISRO Launch this year . If successful , it will herald new era in Indian Space Age . This has to be successful . ISROs and India's reputation is at stake. But given the confidence exudated by Indian scientists after launch of INRSS-1 when they openly talked about upcoming GSLV launch, it seems it's going to be fine. God bless ISRO !
