This flight, designated GSLV-D5, utilizes a Mk II variant with an India built cryogenic engine capable of launching 2,500 kg into geostationary transfer orbit. Currently under development is the Mk III, which is a technological successor to the GSLV capable of launching up to 5,000 kg. The C-25 upper stage and CE-20 engine for Mk III have been delayed due to problems with the Mk II CE-7.5 engine. The suborbital test flight of the Mk III launcher, without its cryogenic third stage, is now planned for April 2014. It will likely be further delayed along with India’s Chandrayaan-2 Moon mission (set for 2015), and India’s Human Spaceflight Program plans if GSLV-D5 is not successful. Mk III will also need several successful launches before it could be ...
