The failure of GSLV-F06 carrying GSAT-5P is the third unsuccessful mission of India's Geo-Stationary Launch Vehicle in its seven flights. The second operational flight GSLV-F02 powered by Russian cryogenic engine failed in July 2006 while the developmental flight GSLV-D3 using maiden indigenous cryogenic stage deviated after takeoff in April. All the GSLV rockets,including today's failed flight,used the Russian cryogenic engines barring the GSLV-D3. Chronology of ISRO's failed missions: December 25,2010: GSLV-F06 launch unsuccessful due to snag in stage-1 April 15,2010: GSLV-D3 developmental flight carrying GSAT4 onboard. Failure. Plunges into sea. July 10,2006: Second operational flight of GSLV (GSLV-F02) with INSAT-4C onboard. Satellite could not be placed in orbit. Rocket falls into sea. September 20,1993: First developmental launch of PSLV with IRS-1E on board. Satellite could not be placed in orbit. July 13,1988: Second developmental launch of ASLV with SROSS-2 onboard. Satellite could not be placed in orbit. March 24,1987: First developmental launch of ASLV with SROSS-1 satellite on board. Satellite could not be placed in orbit. August 10,1979: First experimental launch of SLV-3 with Rohini Technology Payload onboard. Satellite could not be placed in the orbit.
