Launching vehicle of Chandrayaan 2
The launching vehicle used for Chandrayaan2 mission is GSLV -MK III (Geosynchronous Satellite Launch Vehicle mark-III). It is for payloads to GTO (Geostationary transfer orbit). It is three-stage medium-lift launch vehicle It can lift loads of four ton class of satellite into a geostationary transfer orbit. The vehicle has two solid strap-ons, a core liquid booster and a cryogenic upper stage.

A strap on the motor is a booster that is attached to the side of the main stage of a rocket. A core liquid booster consists of liquid fuel and oxidiser as a booster to give hybrid rocket an extra boost at take off. A Cryogenic rocket stage is more efficient and provides more thrust for every kilogram of propellant.
Geosynchronous Satellite is a satellite in a geosynchronous orbit with an orbital period( Orbital period is the time taken by the astronomical object to make one complete orbit around another astronomical object) which is same as the earth rotational period that means 23 hours 56 minutes 4 seconds.

Hello there, just became aware of your blog through Google, and
found that it’s truly informative. I’m going to watch out
for brussels. I will be grateful if you continue this in future.
Numerous people will be benefited from your writing. Cheers!
