The test firing of Newton 440 was done on September 22, 2014 which came out to be successful, which boosted up the confidence and hopes of the Indian Space and Research Organisation engineers about the engines performance on the final day of run, Wednesday, September 24, 2014.
The final firing of the spacecraft will be done day after which will be fired for 24 minutes from7:17 am. The spacecraft will periapsis of 432 km and an apoapsis of 80,000 km.
This is going to be a big step in the history of ISRO. Eight small thrusters on board the spacecraft will fire with the main 440 Newton engine.
The test firing helped to correct the trajectory of the orbiter – the altitude of the spacecraft was brought down by 200 km. Mars orbiter began at 2.30 p.m. on Monday and there was no hitch at all in its performance.
Earlier spacecrafts were fired on December 1, 2013 to catapult India’s Mars orbiter from its earth-orbit into sun-centric orbit and its sojourn to Mars began.
The Chairman and the Mission Director, K. Radhakrishnan and V. Kesava Raju respectively are happy and proud.
They are happy and content with the way things are going with the spacecraft and all are just hopeful that on the final day things go as per the plan.
Once the engine is finally launched it will be able to reveal many secrets about the red planet and much more.
