about three minutes, raising its apogee to and the perigee to . This extended its orbit to a distance more than half the way to the Moon. In this orbit, the spacecraft took about six days to go around the Earth once. Final orbit burn The fifth and final orbit raising manoeuvre was carried out on 3 November 2008 at 23:26 UTC when the spacecraft's engine was fired for about two and a half minutes resulting in Chandrayaan-1 entering the Lunar Transfer Trajectory with an apogee of about . Lunar orbit insertion Chandrayaan-1 completed the lunar orbit insertion operation on 8 November 2008 at 11:21 UTC. This manoeuvre involved firing of the liquid engine for 817 seconds (about thirteen and half minutes) when the spacecraft passed within from the Moon. The satellite was placed in an elliptical orbit that passed over the polar regions of the Moon, with aposelene and periselene. The orbital period was estimated to be around 11 hours. With the successful completion of this operation, India became the fifth nation to put a vehicle in lunar orbit. First orbit reduction First Lunar Orbit Reduction Manoeuvre of Chandrayaan-1 was carried out on 9 November 2008 at 14:33 UTC. During this, the engine of the spacecraft was fired for about 57 seconds. This reduced the periselene to while aposelene remained unchanged at 7,502 km. In this elliptical orbit, Chandrayaan-1 took about ten and a half hours to circle the Moon once. Second orbit reduction This manoeuvre was carried out on 10 November 2008 at 16:28 UTC, resulting in steep decrease in Chandrayaan-1's aposelene to and its periselene to , During this manoeuvre, the engine was fired for about 866 seconds (about fourteen and a half minutes). Chandrayaan-1 took two hours and 16 minutes to go around the Moon once in this orbit. Third orbit reduction Third Lunar Orbit Reduction was carried out by firing the onboard engine for 31 seconds on 11 November 2008 at 13:00 UTC. This reduced the periselene to , while the aposelene remained constant at 255 km. In this orbit Chandrayaan-1 took two hours and 9 minutes to go around the Moon once. Final orbit Chandrayaan-1 spacecraft was placed into a mission-specific lunar polar orbit of above the lunar surface on 12 November 2008. In the final orbit reduction manoeuvre, Chandrayaan-1's aposelene and periselene were both reduced to 100 km. In this orbit, Chandrayaan-1 takes
