First orbit-raising manoeuvre of spacecraft held

The first orbit-raising manoeuvre of India’s Mars Orbiter Spacecraft was performed in the wee hours on Thursday, two days after its successful launch by PSLV C-25 into orbit around the Earth.

At 1.17 am the 440 Newton Liquid Engine of the spacecraft was fired for 416 seconds by commanding it from Spacecraft Control Centre (SCC) at ISRO Telemetry, Tracking and Command Network (ISTRAC) here.

‘With this engine firing, the spacecraft’s apogee (farthest point to Earth) has been raised to 28,825 km, while its perigee (nearest point to Earth) is at 252 km’, Bangalore-headquartered ISRO said in a statement.

The spacecraft on India’s first interplanetary mission was launched into an elliptical earth orbit.
