What is the News?

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

About Next-Gen Launch Vehicle (NGLV)

In NGLV, ISRO is looking at a cost-efficient, three-stage to-orbit, a reusable heavy-lift vehicle with a payload capability of ten tonnes to Geostationary Transfer Orbit (GTO).

Propulsion: NGLV will have semi-cryogenic propulsion (refined kerosene as fuel with liquid oxygen (LOX) as oxidiser) for the booster stages which is cheaper and more efficient.

NGLV will feature a simple, robust design which allows bulk manufacturing, modularity in systems, sub-systems and stages and minimal turnaround time.

Potential applications: The uses of NGLVs will be in the areas of launching communication satellites, deep space missions, future human spaceflight and cargo missions.

What needs to be done to improve the NGLVs?

It is important to develop a ”business model” for NGLV. This will include launching commercial satellites and national missions as well as ensuring industry participation from the start.
