Context

ISRO is developing the Next Generation Launch Vehicle (NGLV), which will replace its ‘trusted work horse’ PSLV in the future.

About NGLV

  • ISRO’s NGLV will be a three-stage reusable heavy-lift vehicle.
  • Geosynchonous Orbit (GEO) takes a satellite around the Earth at a rate of once per day, keeping it roughly in the same area over the ground. 
  • Geostationary Orbit (GSO) is a geosynchronous orbit with an inclination of zero, meaning, it lies on the equator.
  • Payload capacity will be around 10 tonnes to Geostationary transfer orbit (GTO) and twice the capacity to Low earth orbit (LEO).
  • Potential applications: areas of deep space missions, launching communication satellites, future human missions and cargo missions.

Significance

  • Cheaper & efficient: NGLV will feature semi-cryogenic propulsion for the booster stages which is cheaper and more efficient.
  • Bulk production: It allows bulk manufacturing and the turnaround time is minimal.

ISRO’s launch vehicles

  • Launch Vehicles are used to carry spacecraft to space. India has two operational launchers:
    • Polar Satellite Launch Vehicle (PSLV)
    • Geosynchronous Satellite Launch Vehicle (GSLV)

About PSLV technology

  • Launched in: 1994
  • Polar Satellite Launch Vehicle (PSLV) is the third generation launch vehicle of India.
  • It is the first Indian launch vehicle to be equipped with liquid stages.
  • Stages: It is a four-staged launch vehicle:
    • first and third stages using solid rocket motors
    • second and fourth stages using liquid rocket engines
  • Important missions:
    • Chandrayaan, 2008
    • Mars Orbiter Spacecraft, 2013 

Verifying, please be patient.
