India (SLV/ASLV/PSLV/GSLV) Flight History by Variant/Year (1979-2010) Page 2 of 2: Comprehensive Orbital Launch Failure List Date Vehicle ID Site Payload Failure Description Result# ---------------------------------------------------------------------------------------------------------- 8/10/1979 SLV-3 SLV3E1 SRI Rohini 2nd stg control (TVC) failure FTO 5/31/1981 SLV-3 SLV3D3 SRI Rohini-2 Low orbit 186x418kmx46deg down in 8 days (LEO) 3/24/1987 ASLV ASLVD1 SRI Rohini 2nd stg fail to ignite, no orbit FTO 7/13/1988 ASLV ASLVD2 SRI SRS2 1st stg control failed 150 sec, no orbit FTO 5/20/1992 ASLV ASLVD3 SRI SROSS-C Stg5 bad spin, low orbit 256x436kmx46deg (LEO)[1] 9/20/1993 PSLV PSLVD1 SRI IRS-1E No orbit due attitude control failure FTO 9/29/1997 PSLV PSLVC1 SRI IRS-1D Stg4 He leak, low orbit 306x822kmx98.5deg (LEO)[2] 4/18/2001 GSLV GSLVD1 SRI GSat-1 Low GTO apogee*, cryo stg3 off 12s early (EEO)[3] 7/10/2006 GSLV GSLVF2 SRI SLP Insat 4C 1st stg strap-on Vikas engine fld T+2 sec FTO [4] 9/02/2007 GSLV GSLVF4 SRI SLP Insat-4CR Low performance, guidance? [EEO][5] 04/15/10 GSLV Mk2 GSLVD3 SRI SLP GSAT 4 3rd Stg failed at start. [FTO][6] 12/25/10 GSLV Mk1 GSLVF6 SRI SLP GSAT-5P Control failed T+47 sec. RSO T+63 sec. [FTO][7] ---------------------------------------------------------------------------------------------------------- Footnotes: [1] Planned circular orbit not achieved. Reentered after 2 months [2] Helium pressurant leak caused 130 m/s shortfall. Planned 817km circular sun synchronous not achieved. IRS-1D used >70% of own propellant to reach 742 x 822 km "functional" orbit. [3] 181x32051kmx19.2deg versus planned 180x35975kmx19.2deg. GSat-1 had insufficient fuel to maneuver to planned geostationary orbit. [4] Thrust controller failure on Vikas engine on one of four strap-on liquid boosters, causing shutdown at T+2sec. GSLV flew on before breaking up and falling into Bay of Begal about 6-7 km downrange. [5] Launch vehicle placed Insat-4CR in 168 x 31,786 km x 15.8 deg orbit, well short of planned 170 x 35,975 km x 21.7 deg GTO. [6] 3rd Stg failed at or near startup. First Indian Cryo Stage [7] Control failed T+47 sec. RSO T+63 sec. # FTO: Failed to Orbit FSO*: Failed Suborbital (EEO): Unintended Eliptical Earth Orbit (GTO): Unintended Geosynchronous Transfer Orbit (LEO): Unintended/Improper Low Earth Orbit "SRI" = Sriharikota, India "SLP" = Second Launch Pad (All other launches at First Launch Pad "TVC" = Thrust Vector Control References: Jonathan's Space Report Launch Vehicle Database "http://www.planet4589.org/space/lvdb/index.html" Encylopedia Astronautica "http://www.astronautix.com/" Gunter's Space Page "http://www.skyrocket.de/space" TRW Space Log 1957-1996, TRW Space & Electronics Group, Redondo Beach, CA.
