HS200 Solid Rocket Booster For Gaganyaan Mission

HS200 Solid Rocket Booster For Gaganyaan Mission:

The Indian Space Research Organization (ISRO) has completed the static test of the human-rated solid rocket booster (HS200) for Gaganyaan programme.

HS200 Solid Rocket Booster:

  • The booster engine is part of the Geosynchronous Satellite Launch Vehicle MkIII (GSLV Mk III) rocket that will carry Indian astronauts to space.
  • The GSLV Mk-III rocket which will be used for the Gaganyaan mission will have two HS200 boosters which will supply the thrust for lift-off.
  • The HS200 is a 20-metre-long booster with a diameter of 3.2 metres and is the world’s second largest operational booster using solid propellants.
  • The HS200 is the human-rated version of the S200 rocket booster of satellite launch vehicle GSLV Mk III, popularly known as LVM3.
  • Since Gaganyaan is a crewed mission, the GSLV Mk-III will have improvements to increase reliability and safety to meet the requirements of ‘human rating.’
  • The S200 motor – the first stage of the LVM3 launch vehicle designed to deliver 4,000 kg satellites to geosynchronous transfer orbit – was configured as a strap-on rocket booster.
  • This full-duration test of the first stage of the launch vehicle marks a major milestone for the Gaganyaan programme.
  • Design and development of the HS200 booster was completed at the Vikram Sarabhai Space Centre (VSSC) in Kerala’s Thiruvananthapuram, and propellant casting was completed at Sriharikota.
  • Out of the three propulsion stages of LVM3, the human-rated versions of the second-stage known as L110-G loaded with liquid propellant and the third stage C25-G with cryogenic propellant are in the final phase of qualification, including tests with static firing.
