Chandrayaan I update

Inching closer to its final destination, India’s first moon-bound spacecraft Chandrayaan-1 on Saturday became the most successful among all Indian space missions with the furthest point in its current orbit around the earth touching 74,715 km. No Indian spacecraft had gone beyond 36,000 km in space till now.“The second orbitraising manoeuver of Chandrayaan-1 space craft was carried out at 05:48 hrs IST this morning (October 25, 2008) when the spacecraft’s 440 Newton Liquid Engine was fired for about 16 minutes by commanding the spacecraft from Spacecraft Control Centre,” an ISRO statement said. “This is the first time an Indian spacecraft has gone beyond the 36,000 km high geo-stationary orbit and reached an altitude twice that height. In this orbit Chandrayaan 1 takes about 25 hours and 30 minutes to go round the earth once,” ISRO officials said. ISRO chairman G Madhavan Nair has called it a ‘record breaking’ day for the mission.
Chandrayaan 1’s initial launch by the PSLV-XL launch vehicle on October 22 placed it in an elliptical orbit around the earth with a perigee (closest point to earth) of 255 km and an apogee (farthest point from earth) of 22,860 km. To reach the moon the spacecraft has to cover a total distance of 3,86,000 km and it is expected to settle into a lunar orbit, 100 km from the Moon on November 8.“When you go further and further, the earth’s influence comes down. The influence of the Moon and Sun becomes pre dominant. Even other planets will have an influence on it,” Nair said. ISRO has reported good conditions for all systems on board Chandrayaan-1.
