An Indian Polar Satellite Launch Vehicle (PSLV) failed to place a navigation satellite into its planned orbit Aug. 31 when the rocket's payload fairing failed to deploy. The PSLV, flying a mission designated PSLV-C39, lifted off on schedule at 9:30 a.m. Eastern from the Satish Dhawan Space Centre on the east coast of India. Initial phases of the launch appeared to go as planned, but observers noted that, as the flight progressed, the vehicle appeared to deviate from its planned trajectory according to telemetry displays shown during the webcast. Launch controllers later confirmed that vehicle's upper stage and payload, the Indian Regional Navigation Satellite System (IRNSS) 1H satellite, had reached a lower orbit than planned. The payload was in an orbit of 167 by 6,555 kilometers, while the planned transfer orbit for the mission was 284 by 20,650 kilometers. See Full Story |
