It is 630 tonne at lift off. We would test only the first two stages and not the cryogenic stage." This is the heaviest rocket India has ever launched. However, the GSLV Mark-III will allow India to place satellites as heavy as 4-tonnes into the GTO. GSLV MkIII, chosen to launch Chandrayaan-2 spacecraft, is a three-stage heavy lift launch vehicle developed by ISRO.
With its 4,000 kg of payload capacity the GSLV Mark III is yet another feather in ISRO's cap. The vehicle has two solid strap-ons, a core liquid booster and a cryogenic upper stage.
