The Indian Space Research Organisation (ISRO) has now admitted that the first few hours after the Ariane 5 ECA launch on 25 July of its Insat 3D combined weather and data relay satellite were not without incident. According to Indian media reports, shortly after the spacecraft’s single solar array had been deployed the Insat 3D satellite began to unexpectedly spin up and all contact was lost for time. According to The Hindu, the control fault was caused by the failure of a telecommand receiver. After communications were restored, the spacecraft was put on a back up receiver and control was successfully recovered. The spacecraft has now completed its circularisation manoeuvres to Geostationary Earth Orbit (GEO) on its way to its final position over 93.5 degrees East.
