ISRO’s own Next-Gen Launch Vehicle may assume PSLV’s role
- The Indian Space Research Organisation (ISRO) is developing a rocket named Next Generation Launch Vehicle (NGLV) to replace the Polar Satellite Launch Vehicle (PSLV).
NGLV (Next Generation Launch Vehicle)
- NGLV will feature semi-cryogenic propulsion (refined kerosene as fuel with liquid oxygen (LOX) as oxidiser) for the booster stages which is cheaper and more efficient.
- A cost-efficient, three-stage, reusable heavy-lift vehicle with a payload capability of 10 tonnes to Geostationary Transfer Orbit.
- NGLV will feature a simple, robust design which allows bulk manufacturing, modularity in systems, sub-systems and stages and minimal turnaround time.
- Potential uses: Launching communication satellites, deep space missions, future human spaceflight and cargo missions.
PSLV (Polar Satellite Launch Vehicle)
- It is an indigenously-developed expendable launch system of the ISRO (Indian Space Research Organization). It was developed in the 1980s.
- Category: 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.
