India's expanding space technology, vision, and aspirations are making waves globally. The Indian Space Research Organisation (ISRO) is making strides towards its future with a new third launch pad at the Satish Dhawan Space Centre in Sriharikota. This revelation came to light in an interview with ISRO Chairman Dr. S. Somanath featured in an English daily.
Dr. Somanath explained that, as of now, we have only a second launch pad. The first launch pad was specifically constructed for the PSLV rockets, and it cannot accommodate the GSLV rockets due to the lack of a cryogenic stage. When the LVM-3 rocket was introduced, we re-engineered the second launch pad.

Now, the LVM-3 features a semi-cryogenic stage. Initial human spaceflights, like the Gaganyaan mission, will be launched from this pad. We have been continuously upgrading and updating this pad for over 20 years. The risk is, if an explosion occurs, we lack an alternative for GSLV launches, halting ISRO's missions entirely.
The necessity for a third launch pad?
The ISRO chief emphasized that a new, advanced, and backup plan is essential for the third launch pad. We're advancing towards the Next Generation Launch Vehicle (NGLV) rockets, which will be assembled horizontally and later raised upright, akin to SpaceX rockets.

This rocket will not be assembled vertically, necessitating a launch pad that allows horizontal assembly and repositioning for launch. The new pad must support this technology. The NGLV will feature more liquid engine boosters, and the jet deflector design will undergo changes.

The jet deflector safely channels the smoke and fire generated beneath the launch pad. All stage tests will occur here, eliminating the need for the Mahendragiri center. The advanced design of this single launch pad will meet multiple requirements.
What's in store for the NGLV rocket?
The NGLV will be a three-stage rocket, with a reusable first stage similar to SpaceX's Falcon which returns intact. This rocket is designed to be cost-effective, matching future needs. Currently, the LVM3 can transport a payload of 9.2 tons to LEO. The goal is to increase capacity to 20 tons. Presently achieving a 4.3-ton payload to the GTO, the aim is to double it to 9 tons. The NGLV aims to accomplish both objectives, with capabilities for recovery from both land and sea, employing SpaceX Falcon-like return technology.
