GSLV Mk.2 (GSat 4) [ISRO]

The indian GSLV (Geostationary Launch Vehicle) series are launch vehicles in the 2500 kg to GTO class, which feature a unusual combination of different kind of stages. The first stage consists of a large solid rocket, derived from the PSLV first stage. It is augmented by four liquid fueled strap-on boosters, which have a longer burn time than stage 1. Each booster is powered by a Vikas engine and remains connected with stage 1 during the flight. The second stage is a liquid fueled stage featuring storable propellants. It is the sam as used in the PSLV and is also powered with a Vikas engine. The cryogenic stage 3 for the Mk.1 version is powered by the russian KVD-1M engine, which was originally developed for a cryogenic version of the Proton launch vehicle. It will be replaced by the Mk.2 version, which features the indian built CS engine.
