More About PSLV-C50:

The 44-metre-high four staged/engine PSLV-C50 is the 22nd flight of PSLV in ‘XL’ configuration (with six strap-on motors hugging the first stage).
The PSLV in the normal configuration is a four-stage/engine expendable rocket powered by solid and liquid fuels alternatively with six booster motors strapped on to the first stage to give higher thrust during the initial flight moments.
The Indian space agency has PSLV variants with two and four strap-on motors, larger PSLV-XL and the Core Alone variant without any strap-on motors. The choice of the rocket to be used for a mission depends on the weight of the satellite and the orbit where the satellite has to be orbited.
