One of the important contribution to this feat is precise orbit estimation. Mars Orbiter Mission was launched on 5th November 2013 from Satish Dhawan Space Centre, Sriharikota, India by India's Polar Satellite Launch Vehicle PSLV-C25. The spacecraft was placed in an elliptical orbit of 248.4 X 23550 km around Earth. MOM revolved about 25 days around the Earth and performed six maneuvers to achieve the escape velocity. After a sequence of five Earth bound maneuvers, the satellite apogee was raised to 190000 km, and through Trans Mars Injection on 30th November, 2013 the spacecraft was allowed to escape Earth sphere of influence and was put into Mars Transfer Trajectory orbit around Sun.
