The maiden flight of the GSLV-Mk Indian rocket-II failed, because the third stage of the rocket did not work as intended. The payload, the communications and technology test satellite GSAT-4 could not be placed in Earth orbit and was lost.
The Mk II version of the GLSV differs from its predecessor in addition to an improved on-board computer and a new telemetry system and a larger payload fairing made of other materials and by another third stage, the Russian technology developed rocket motors used in India instead. After taking off from Satish Dhawan Space Centre at Sriharikota Island on India’s southern coast clock 12:57 EDT (16:27 clock time) rocket worked the first two stages of work as intended. On the ignition of the third stage, however, followed significant flight path deviations, and 505 seconds after the start burst reception of telemetry data from the rocket .
In a first opinion said chairman Indian Space Research Organisation ISRO K. Radhakrishnan with the firing of the cryogenic, i.e. with liquid hydrogen and liquid oxygen fueled third stage of the rocket had been launched on-board computer, and telemetry data would confirm the ignition. Then came the rocket is, however, wobbling, which is probably not ignited by, or not working properly.
The actual trajectory of the rocket followed by the failure of third stage probably curve, rocket and payload fell back a ballistic toward Earth. The missile, it should have planned how to work, at the launch 2,200-pound communications and technology test satellite GSAT-4 in a Geotransfer orbit suspend, from where the satellite using its own engines, a position at 82 degrees East in geostationary orbit would in reach .
The flight, ISRO regarded as a flight test mission, and described the carrier so as GSLV-D3, where the D stands for Development . The next launch of GSLV Mk-II in the version should be made within one year.
