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.
