Launch History
All GSLV launches have been conducted from the Satish Dhawan Space Centre in Sriharikota.
| Flight | Launch date/time (UTC) | Variant | Launch Pad | Payload | Payload Mass | Result | Note(s) |
|---|---|---|---|---|---|---|---|
| D1 | 18 April 2001 10:13 |
Mk.I(a) | First | GSAT-1 | 1,540 kg | Failure | Developmental Flight, payload placed into lower than planned orbit, and did not have sufficient fuel to reach a usable orbit. |
| D2 | 8 May 2003 11:28 |
Mk.I(a) | First | GSAT-2 | 1,825 kg | Success | Developmental Flight |
| F01 | 20 September 2004 10:31 |
Mk.I(b) | First | EDUSAT | 1,950 kg | Success | First operational flight |
| F02 | 10 July 2006 12:08 |
Mk.I(b) | Second | INSAT-4C | 2,168 kg | Failure | Both rocket and satellite had to be destroyed over the Bay of Bengal after the rocket's trajectory veered outside of permitted limits. |
| F04 | 2 September 2007 12:51 |
Mk.I(b) | Second | INSAT-4CR | 2,160 kg | Partial Failure | Partial launch failure, apogee lower and inclination higher than expected, due to carrier rocket underperformance. Eventually the 2160 kg payload reached the designated geostationary transfer orbit. There were reports that the mission life of the satellite had decreased by five years as the thrusters had to burn extra fuel to place the satellite in the correct orbit. However, ISRO later refuted this claim dismissing it as false. |
| D3 | 15 April 2010 10:57 |
Mk.II | Second | GSAT-4 | 2,220 kg | Failure | First flight test of the ISRO designed and built Cryogenic Upper Stage. Failed to reach orbit due to malfunction of Fuel Booster Turbo Pump (FBTP) of the Cryogenic Upper Stage. |
| F06 | 25 December 2010 10:34 |
Mk.I (c) | Second | GSAT-5P | 2,130 kg | Failure | First flight of GSLV Mk.I (c) Destroyed by range safety officer after loss of control of liquid fuelled boosters. |
| Planned launches | |||||||
| F05 | Early 2013 | Mk.I(c) | GSAT-6 | ISRO is planning to launch GSLV space mission with indigenously built cryogenic engine early in 2013, an ISRO official said in August 2012. | |||

Famous quotes containing the words launch and/or history:
“I had often stood on the banks of the Concord, watching the lapse of the current, an emblem of all progress, following the same law with the system, with time, and all that is made ... and at last I resolved to launch myself on its bosom and float whither it would bear me.”
—Henry David Thoreau (1817–1862)
“The history of the world is none other than the progress of the consciousness of freedom.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
