We are very happy to be a part of this adventure,' said Pieters, who was in charge of the moon mineralogy mapper of Chandrayaan-1.

'What we have not achieved is our ultimate goal, which was a much more extended mission that was to be achieved during the full two years. But, the first phase of what we wanted to accomplish, we were able to accomplish and we will be working with the data in the future,' she averred.

Asked to comment on ISRO chairman G Madhavan Nair's claim that 95 per cent of the objectives were achieved, Pieters was noncommittal. 'I can't claim in one way or the other as I have information only on my experiment,' she maintained.
