In the final lap, the operation is scheduled to be performed at 07:17:32 hrs on Wednesday by firing the LAM along with eight smaller liquid engines for about 24 minutes.

The tricky manoeuvre involves slowing down the spacecraft now moving at benumbing speed to be captured in the Martian orbit, success of which would make India the first country to go to Mars in the maiden attempt.

Prime Minister Narendra Modi will witness the crucial Mars Orbiter Insertion at the Spacecraft Control Centre at ISRO Telemetry Tracking and Command Network (ISTRAC) here.
The main engine on the spacecraft, in slumber since the 300-day journey began, was woken up on Tuesday, though for four seconds after a successful crucial manoeuvre that has raised the confidence level of ISRO scientists.

The 440 Newton Liquid Apogee Motor (LAM) on Mars Orbiter Spacecraft was last fired on December 01, 2013. Yesterday's twin operation also involved a trajectory correction that means the spacecraft is on course.

In the final action tomorrow, the orbiter has to be slowed down from 22.1 km per second to 4.4 km per second in relation to the red planet to be captured by the Martian orbit. The engine would be fired for 24 minutes to reduce its velocity and insert it into the Martian orbit.
ISRO has uploaded commands to help the spacecraft automatically enter the orbit.
