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?"
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.
Subramanian, 33, who was on Tuesday the toast of the astronomy world, managed what ISRO and NASA couldn't through his close examination of before and after images of the scheduled landing.
In several places, from roof-tops and flyovers, people showered petals and garlands on the truck.
