GSLV Mk III-D1 OR GSAT-19 Mission – Another Success Story

Last updated on September 30, 2017 by Clear IAS Team

GSLV Mk III -GSLV Mark III D1/GSAT-19 MissionGSLV Mk III-D1 launched GSAT-19 on June 05, 2017 from the Satish Dhawan Space Centre SHAR (SDSC SHAR), Sriharikota. The first developmental flight of GSLV Mk III (the GSLV-Mk III-D1) successfully placed GSAT-19 satellite to a Geosynchronous Transfer Orbit (GTO).

Know more about GSLV Mk III

  • GSLV Mk III is a three-stage heavy lift launch vehicle developed by ISRO.
  • It is a three-stage vehicle with two solid motor strap-ons (S200), a liquid propellant core stage (L110) and a cryogenic stage (C25).
  • GSLV-Mk III is capable launching 4 ton class of satellites to Geosynchronous Transfer Orbit (GTO).
  • GSLV Mk III is designed to carry 4 ton class of satellites into Geosynchronous Transfer Orbit (GTO) or about 10 tons to Low Earth Orbit (LEO), which is about twice the capability of GSLV Mk II.

Then, what is GSLV-Mk III-D1?

GSLV MkIII-D1

GSLV-Mk III-D1 is the first developmental flight, carrying 3136 kg GSAT-19 satellite to a Geosynchronous Transfer Orbit (GTO). The vehicle is configured with a 5 m ogive payload fairing and slanted strap-on nose cone to provide aerodynamic robustness.

Note: The first experimental flight of LVM3, the LVM3-X/CARE mission lifted off from Sriharikota on December 18, 2014, and successfully tested the atmospheric phase of flight. Crew module Atmospheric Reentry Experiment was also carried out in this flight. The module reentered, deployed its parachutes as planned and splashed down in the Bay of Bengal.

3 stages of GSLV Mk III – The Mechanism

The two strap-on motors of GSLV Mk III are located on either side of its core liquid booster. Designated as ‘S200’, each carries 205 tons of composite solid propellant and their ignition results in vehicle lift-off. S200s function for 140 seconds. During strap-ons functioning phase, the two clustered Vikas liquid Engines of L110 liquid core booster will ignite 114 sec after lift -off to further augment the thrust of the vehicle. These two engines continue to function after the separation of the strap-ons at about 140 seconds after lift -off.

    GSLV MK-III has capacity to lift the weight of double of its earlier satellite launch vehicle PSLV. Definitely it’s proud for india. It will revolutionise India space program. And the day is not far when isro will send Indian astronat to other planet because GSLV MK-III has less noise and vibration ie support to astronat travel.

    I hope isro will open space travel in 2025
