Chennai, Sep 24 - The sensational discovery of water molecules on the lunar surface by an instrument owned by the US's National Aeronautics and Space Administration (NASA) and carried by India's Chandrayaan-1 has been termed by scientists as a 'very precious find'.

'Moon water is more precious than gold,' an Indian space scientist told IANS, declining to be named.

He said the presence of water makes a lot of difference for future explorations. 'For instance, we may not have to carry water from earth,' he added.

However, he said that a whole lot of tests have to be done to determine whether the water is consumable by humans.

The immediate fallout of the current find on the Chandrayaan-2 mission slated for 2012/2013 is that the moon lander that would go there can land precisely near the moon water and conduct the necessary tests there.

According to the scientist, the data from other equipments carried by Chandrayaan-1 are being studied and the result will be announced in due course of time.

'It includes the data generated by the Indian equipments on Chandrayaan-1.
