Chennai sources stated that after the debris from Chandrayaan-2’s vikram moon lander was found on tuesday nasa credited a chennai based techie, who worked independently, for alerting them about its presence. Meanwhile, Shanmuga Subramanian, 33, found the debris from the vikram moon lander that scientists had been looking for and helped guide them to the spot where it had crashed. Shanmuga Subramanian, who made the discovery, told on tuesday “It was something challenging as even nasa can’t find out so why can’t we try out? And that’s the thought that led me to search for vikram lander".
Furthermore, he looked for it on the images from NASA’s Lunar Reconnaissance Orbital (LRO) Camera that the US space agency had released to the public. Apparently LRO Project Scientist Noah Petro told that “The story of this really amazing individual (who) found it, helped us find it, is really awesome.” Moreover, he said that Subramanian “is totally independent of the LRO, totally independent of the Chandraayan 2 team, just someone who is very interested in the Chandraayan 2 mission (who) used our data and identified a spot where there was a change that we had not identified”.
Petro added, “He went through the image, looking pixel by pixel and found that spot". Reportedly Subramanian works in chennai as a software architect and told in an email interview that he did the search in his spare time. Perhaps nasa said it released a mosaic image of the site on september 26 (but taken on september 17), inviting the public to compare it with images of the same area before the crash to find signs of the lander. Apparently Subramaniam was the first person to come up with positive identification and he said NASA's inability to find the lander on its own had sparked his interest.
