Next-Gen Launch Vehicle (NGLV)

Next-Gen Launch Vehicle (NGLV)

Why in news?

The Indian Space Research Organisation (ISRO) is developing a Next-Gen Launch Vehicle (NGLV), which will one day replace operational systems like the Polar Satellite Launch Vehicle (PSLV)

why  NGLV?

  • ISRO is looking at a cost-efficient, three-stage to orbit, reusable heavy-lift vehicle with a payload capability of ten tonnes to Geostationary Transfer Orbit (GTO).
  • NGLV will feature semi-cryogenic propulsion (refined kerosene as fuel with liquid oxygen (LOX) as oxidiser) for the booster stages which is cheaper and efficient
  • NGLV will feature a simple, robust design which allows bulk manufacturing, modularity in systems, sub-systems and stages and minimal turnaround time.

Potential uses

  • It will be in the areas of launching communication satellites, deep space missions, future human spaceflight and cargo missions.

PSLV Basic

  • It comes in the category of medium-lift launchers with a reach up to various orbits, including the Geo Synchronous Transfer Orbit, Lower Earth Orbit, and Polar Sun Synchronous Orbit.
  • All the operations of PSLV are controlled from the Satish Dhawan Space Center, Sriharikota, east coast, India
  • It has a four-stage system comprising a combination of solid and liquid-fuelled rocket stages.
  • The flagship launcher has a payload capacity of 1,050 kg for launching into the Geo Synchronous Transfer Orbit and 1,600 kg for the Polar Sun Synchronous Orbit.
