BANGALORE, India โ€” Indiaโ€™s Chandrayaan-1 lunar orbiter, which was launched Oct. 22, has successfully executed an orbit-raising maneuver that puts it on course to reach the Moon by this weekend.

The Indian Space Research Organisation (ISRO) said in a press release Nov. 4 that Chandrayaan-1 has entered Lunar Transfer Trajectory after a fifth and final orbit-raising maneuver carried out early that day. During this maneuver, the spacecraftโ€™s onboard motor was fired for about 150 seconds, raising its apogee to about 380,000 kilometers โ€” the Moonโ€™s average distance from Earth.

โ€œChandrayaan-1 will approach the Moon on November 8, 2008, and the spacecraftโ€™s liquid engine will be fired again to insert the spacecraft into lunar orbit,โ€ the release said. ISRO said that all systems onboard the spacecraft are performing normally.
