In one of the most crucial manoeuvres since the launch of India's maiden moon mission, Chandrayaan-1, ISRO scientists are slated to inject the spacecraft into the lunar orbit today.
"The lunar orbit insertion (LOI) will start around 5 p.M. and last around 800 seconds," ISRO spokesperson S Satish told PTI here.
Once the operation is completed, it will be in a 7,500 km X 500 km elliptical orbit around the moon.
"It (Chandrayaan-1) will enter the moon's orbit. It will be captured by lunar gravity," Satish said.
Chandrayaan-1 was launched from the spaceport of Sriharikota on October 22.
