According to ISRO Chairman two crucial tests have still to be completed on the cryogenic stage:
  • testing in vacuum
  • endurance of the fuel booster turbo pump

    let's hope everything goes smoothly this time !

    By the way.. I was looking at a previous GSLV launch video (see at the end) and I realized they ignite the boosters 4sec before the S139 main stage.

    How do they prevent the launcher from moving, tilting or lifting-off during this phase ?

    With the mass of the launcher (402 t) and the thrust of the 4 Vikas (209t) (source wikipedia) they must have some sort of hold down mechanism or pyro bolts ?

    GSLV's next launch in April: Veeraraghavan

    "Most tests have been completed except for the high altitude test, which validates the mission of our cryogenic engine. We hope to complete this and launch the GSLV mission by April 2013," Veeraraghavan said

    GLSV will be moved to Sriharikota for July launch:

    Well, this article hints at a launch date potentially drifting into August...
    (45 days are a minimum between 2 launches FLP/SLP)

    Since PSLV-C22 launch has been delayed to end June, GSLV D5 launch can't take place before August

    can you provide a source to back up this claim? There are multiple reports on the web saying that PSLV C-22 will be launched as scheduled on June 12.

    ISRO sources said preparations are on at the second launch pad at the spaceport of Sriharikota for the launch of GSLV-D5 (Geosynchronous Satellite Launch Vehicle-Development flight 5) in August.

    GSLV-D5 aerodynamic characterisation has been revisited following the back-to-back failure of GSLV flights - one with indigenous cryogenic engine and another with a Russian-made one in 2010.

    Force measurements, steady and unsteady pressure measurements and aero elastic tests have already been conducted using wind tunnel models at National Aerospace Laboratory, Bangalore and Glavkosmos, Russia.

    Computational fluid dynamics simulations have been carried out in-house for incremental effects on protrusion, overall aerodynamic load distribution and distribution on protrusions, according to ISRO.

    GSLV-D5 would carry GSAT-14 satellite with six extended C band and six Ku band transponders, envisaged to enhance communication transponder capacity.

    The satellite employs the standard 2,000 Kg class bus (I-2K) with a power handling capability of around 2.5 KW and a lift-off mass of 1,980 kg, the space agency added.

    Tentative launch window is between July 25th - August 10th. RLV-TD will fly from FLP in september. (http://www.defence.pk/forums/indian-defence/241849-rlv-airframe-under-construction.html)
