Why was the PSLV used for launching Chandrayaan-1?

Answer 1

India has two space rockets capable of launching satellites and space probes. The Polar Satellite Launch Vehicle (PSLV) and the Geosynchrounous Satellite Launch Vehicle (GSLV). Given the Payload mass of 1,308 kilograms of Chandrayaan-1, the PSLV was adequate to launch the Chandrayaan-1 into Earth orbit prior to commencing it's journey to the Moon. The Geosynchronous Satellite Launch Vehicle (GSLV) is a newer generation satellite launch vehicle capable of putting into Geostationary Earth orbit much heavier payloads up to 2500 kg.
