Everything about ISRO's Next Generation of Launch Vehicles (a.k.a The NGLV)

Everything about ISRO's Next Generation of Launch Vehicles (a.k.a The NGLV)

On 18th December 2024,
Government was just too happy as they had approved back to back multiple projects of ISRO at same time like Chandrayaan 4, Venus Orbiter Mission, Bhartiya Antariksh Station & finally the NGLV.

So NGLV stands out for Next Generation Launch Vehicle.

It is 3 stage rocket where it's 1st stage would be reusable like Falcon 9.
It would have Grid fins & Landing legs & would be powered by ISRO Future Methane & Liquid Oxygen fueled Rocket Engines.

With a height of 92 meters and 5 meters in diameters, it's estimated cost would be around 1.5x of ISRO's GSLV MK3 rocket (est. cost of NGLV: 90 Million $)

Government has allotted the budget of 8239Cr Rs. to develop it within 8 years of time and first launch to be expected after 7 years.

It would take 3 development flights before being certified for commercial use and it is designed to be reused for atleast 10 times (it's just conservative number).

But there are lots of questions surrounding the NGLV like,
Why NGLV has 3 stages??
Why NGLV is so long??
Why NGLV has 5m diameter??
&
Whether ISRO is gonna integrate it vertically or horizontally??

So if you wants to know more about it,
