Notable missions

edit

GSLV MK. I flight D1

edit

This was the first developmental flight of the GSLV Mk.I featuring Russian cryogenic engine KVD-1. It was used to place an experimental satellite GSAT-1 into the orbit. However, due to sub-optimal performance and lack of fuel the vehicle did not achieve the intended orbit and the satellite had to maneuver itself using onboard fuel to correct the shortfall. ISRO claims the launch to be successful.[1][2] In a 2014 interview, ISRO Chairman K. Radhakrishnan attributed the failure to incorrect mixture ratio used in the cryogenic upper stage.[3][1][4]

GSLV MK. II flight D5

edit

This was the second test flight with indigenous cryogenic stage CE-7.5 and the first successful launch with the CE-7.5. The flight lifted and successfully placed the 1,982 kilograms (4,370 lb) GSAT-14 into the orbit. This flight became the harbinger of successful launch with the indigenous cryogenic stage.[5][6][7]

GSLV MK. II flight F09

edit

This was the fourth consecutive successful flight of GSLV Mk. II with indigenous cryogenic engine. The flight placed the regional satellite South Asia Satellite was previously named as South Asian Association for Regional Cooperation (SAARC) Satellite.[8][9][10][11] The satellite was a gift from India to its neighbors to bolster Prime Minister Narendra Modi's neighborhood first policy.[12] Afghanistan, Bangladesh, Bhutan, Maldives, Nepal and Sri Lanka are the users of the multi-dimensional facilities provided by the satellite.

Launch history

edit

As of 17 February 2024, rockets from the GSLV family have made 16 launches, resulting in 10 successes, four failures, and two partial failures.[13] All launches have occurred from the Satish Dhawan Space Centre, known before 2002 as the Sriharikota Range (SHAR).

Mk I Second   INSAT-4C 2168 kg GTO INSAT Failure
One of the L40 strap-on engines failed at lift-off. Both rocket and satellite had to be destroyed over the Bay of Bengal after the rocket's trajectory veered outside permitted limits.[16]
F04 2 September 2007
12:51
Mk I Second   INSAT-4CR 2160 kg GTO INSAT Partial failure
High roll rate build-up due control system malfunction on one L40 strapon resulted in premature shutdown of other strap-on stages.[17] Due to an error in the guidance subsystem achieved orbit had lower apogee and inclination higher than expected.[18] Orbit corrected through satellite, eventually the INSAT-4CR was placed in its slot.[19][20][21] Satellite completed its planned design life while it was fully operational. ISRO claims this GSLV flight to be successful.[22]
