The Indian Space Research Organisation (ISRO) is on the verge of finalizing the design of its Next Generation Launch Vehicle (NGLV). This new heavy-lift rocket is poised to take over the reins from the PSLV, ISRO’s workhorse that has served the nation for decades.

While the NGLV’s design is nearing completion, ISRO officials are awaiting government approval to proceed with the next stage of development. This green light is crucial for translating the design into a functional launch vehicle.

The NGLV is being designed as a cost-effective and reusable alternative to the PSLV. This three-stage to orbit vehicle boasts a significant payload capacity of ten tonnes to GTO (Geostationary Transfer Orbit).

Key Features of the NGLV

  • Enhanced Payload Capacity: The NGLV boasts a targeted payload capacity of ten tonnes to GTO (Geostationary Transfer Orbit), a substantial leap from the PSLV’s capabilities. This will allow ISRO to launch heavier communication satellites and support more ambitious deep space missions.
  • Cost-Effectiveness: ISRO is prioritizing cost-efficiency in the NGLV’s design. The three-stage to orbit architecture and focus on reusability aim to make NGLV launches more economical.
  • Modular Design: The NGLV will feature a modular design, enabling mass production and easier maintenance. This modularity extends to its systems, subsystems, and stages, facilitating faster turnaround times between launches.
  • Semi-Cryogenic Propulsion: The NGLV will utilize a semi-cryogenic propulsion system, employing refined kerosene as fuel and liquid oxygen (LOX) as the oxidizer for its booster stages. This offers a balance between performance and cost-effectiveness.
