ISRO chief's comments came after NASA said that it had found the remains of the Vikram lander by its Lunar Reconnaissance Orbiter and credited the discovery to Chennai-based amateur astronomer and engineer Shanmuga Subramanium.
NASA posted images clicked by its Lunar Reconnaissance Orbiter camera, showing the site's changes on the Moon and the impact point before and after the spacecraft had made a hard-landing on the lunar surface.
The precise location of the spacecraft in the lunar highlands has yet to be determined.
On October 3, Subramanian, a Chennai-based mechanical engineer, had tagged the Twitter handles of NASA, LRO and ISRO in a tweet, asking, "Is this Vikram lander? (1 km from the landing spot) Lander might have been buried in Lunar sand?"
