The models comes in two different versions. The first from 1967 and a later version from 1969.



In 1962 India started work on the Thumba Equatorial Rocket Launching Station (TERLS).

The first sounding rocket launched here was a Nike-Apache rocket on 21 Nov 1963.

But work started to develop a pure indian sounding rocket. This was known as The Rohini Sounding Rocket (RSR) program. The single-stage Rohini (RH-75) rocket was a solid powered rocket. It was weighing 32 Kg with an additional 7 Kg payload. It was launched on November 20, 1967.

It reached an altitude of around 10 km. The rohoni RH-75 programme led to other and larger sounding rockets. But the experiences from working with solid rockets finally led to the development of real space launchers like Indias GSLV (Geo-Synchronous Launch Vehicle) and PSLV (Polar Satellite Launch Vehicle)
