The Indian Space Research Organisation (Isro) has successfully conducted an experimental test-flight of GSLV MK III carrying an unmanned crew module to be used in future manned space missions. The rocket soared from the launch pad after a 24-hour countdown and the crew module separated from the rocket then re-entered earth's atmosphere at 80 km. It then followed an uncontrolled trajectory into the Bay of Bengal some 180 km off the Andaman Nicobar Islands. The flight also tested the parachute deployment system of the crew module that has to work in a cluster formation to slow down the module and reduce atmospheric friction and thermal corrosion during its free fall back to the surface. Chairman K Radhakrishnan said the performance of solid and liquid propulsion stages happened as expected and the crew module was plunged into the sea. The next developmental flight will be done in the next two years. GSLV Mark III is Isro's most advanced launch vehicle capable of injecting heavier satellites like the GSAT 19e.
