Radhakrishnan announced that the launch had to be postponed by a week as a result of a delay of a crucial telemetry ship reaching Fiji Islands. The launch was rescheduled for 5 November 2013.[27] The PSLV rocket lifted off at 09:08 UTC (2:38 p.m. IST), and placed the satellite into Earth orbit at 09:50 UTC,[28] with a perigee of 264.1 km, an apogee of 23,903.6 km, and inclination of 19.20 degrees,[29] with both the antenna and all three sections of the solar panel arrays being deployed.[30] During the first three orbit raising operations, ISRO has progressively tested the autonomy functions of the spacecraft that are essential for trans-Mars injection and Mars orbit insertion.[31] The systems tested satisfactorily are: • The prime and redundant chains of gyros and accelerometers. • Liquid motor attitude control thrusters. • Attitude, orbit control electronics and associated logics for their fault detection isolation, and reconfiguration. • Functioning of the prime and redundant star sensors.
