The above image shows the different types of rockets used by the Indian Space Administration (ISRO). SLV and ASLV are no longer used. We now usually use PSLV and GSLV. India is yet to test GSLV MK-3 which could carry twice the weight of the normal GSLV. Our GSLV had already made a record by carrying 10 satellites succesfully in one go. India is also trying to get a hand on the Re-usable launch vehicles which would drastically cut-down the expenses and revolutionize the future missions.
