He also said lessons will be learnt from Chandrayaan-I and this failure would not delay the launch of Chandrayaan-II.

'There are some marginal corrections needed,' he said, adding that he would be meet Prime Minister Manmohan Singh next week to speak to him about the mission.

Though ISRO has aborted the mission, the 514-kg Chandrayaan will remain in lunar orbit for over a year and crash onto the moon's surface subsequently.

'We will use the radars of Russia and the US to keep a track of the spacecraft in the lunar orbit and its whereabouts,' ISRO director S. Satish told IANS in Bangalore.

Admitting that the two-year timeframe for the mission was too long and premature, the official said some of the experiments were rescheduled and advanced to ensure the data was collected in the first few months of its expedition.

'None of the lunar missions has been for more than a year. Many of them last six-seven months whereas our mission lasted for about 10 months against heavy odds, including the hostile lunar environment, solar radiation and other variations in the space,' Satish asserted.

Unfazed by the dramatic reverses encountered by Chandrayaan, the Indian space community remains upbeat about the achievements of the ambitious mission in an uncharted arena.

'We have achieved the engineering or technology objectives of the mission by flying the spacecraft 400,000 km to the moon, inserting it into the lunar orbit and placing the Indian tricolour on the lunar surface Nov 14 without hitch,' Nair noted.

Similarly, the scientific objectives such as the chemical and mineralogical mapping of the lunar surface using sophisticated sensors, conducting high-resolution remote-sensing of the moon in visible, near infrared, low-energy and high energy x-ray regions and three dimensional atlas of the near and far sides of the moon were also accomplished.

'We have received excellent data from all the 11 instruments and the scientific community and the international agencies participating in the mission are very happy with the quality of the data,' Satish claimed.
