Bangalore, July 12: G Madhavan Nair, Chairman of Indian Space Research Organisation (ISRO), on Sunday expressed satisfaction with the successful collection of data about the moon by Chandrayaan, country''s maiden lunar mission.

Madhavan Nair stated this while addressing the 9th convocation of International Institute of Information and Technology at Bangalore on Sunday.

He mentioned that the tracking and detection of several factors by Chandrayaan are important steps in mapping the mineralogical composition of moon''s surface which in turn would enable further study in its origin and evolution.

"I think I am happy to say that Chandrayaan has been completely successful in collecting all the data what we wanted. First was the three dimensional of the lunar surface, also getting the mineral content of the surface and then trying to use the extra instruments," said G. Madhavan Nair.

"All this went on very well and we are more or less very happy that the mission is complete," he added.

Chandrayaan-1 was launched on October 22 last year.

Madhavan Nair also added that the second moon mission would be launched by 2012. (ANI)
