ISRO scientists have successfully test-fired main liquid engine on India’s Mars orbiter spacecraft, the Mangalyan, which is scheduled to enter the Mars Orbit Insertion at 7.30am on 24th September

The Indian Space Research Organisation (ISRO) on Monday said that its scientists have successfully test-fired main liquid engine on India’s Mars orbiter spacecraft.

“We had perfect burn for four seconds as programmed. The trajectory has been corrected,” ISRO said.

The Mars Orbiter Mission will now go ahead with the plan for Mars Orbit Insertion.

Earlier in the day, cruising towards its historic rendezvous with the red planet, India’s Mars Orbiter Mission (MOM) entered the Mars Gravitational Sphere of Influence ahead of its scheduled Orbit Insertion on 24th September.

“Our navigators’ calculations show that MOM has entered the Gravitational Sphere of Influence of Mars,” ISRO said on its social networking site, adding, the spacecraft was within 5.4 lakh km radius of the Mars’ Gravitational Sphere of Influence.

After being launched from ISRO’s spaceport of Sriharikota on 5th November last year, the MOM had left Earth’s orbit on 1st December and began its historic voyage to put India on the list of elite nations, which has sent a mission to Mars.

“MOM has entered the Mars Gravitational Sphere of Influence this morning and we will perform certain procedures on the mission today. The fourth trajectory correction manoeuvre and test firing of Main Liquid Engine will be test fired for 3.968 seconds,” an ISRO official said.

The spacecraft is scheduled to enter the Mars Orbit Insertion at 7.30am IST on 24th September.

The crucial fourth trajectory correction manoeuvre and test fire of the main liquid engine on the spacecraft is scheduled for 2.30 pm.

The MOM, India’s first interplanetary mission, was launched by India’s workhorse Polar Satellite Launch Vehicle from the spaceport of Sriharikota in Andhra Pradesh.
