Well, Chennai's own Shanmuga Subramanian, otherwise known to the city's residents as the man behind the Chennai Rains Live page on Facebook. He is an engineering graduate from the Government Engineering College in Tirunelvelli. Hussain, on Tuesday, took to the micro-blogging website, to state that India is becoming a huge source of Space debris, due to its space missions. His regular updates regarding rains in Chennai with the help of radar data and satellite imagery regularly helps citizens prepare for weather-related eventualities.
On curious questions about how he stumbled upon the debris, which has provided a sort of on the date of the Lander, he casually says that what he did was not rocket science. "I used to spend up to seven to eight hours in the initial days (in the last week of September),"he said".
"It was quite hard, but I spent some effort", Mr Subramanian told AFP after announcing his discovery on Twitter in October. "I searched around the north of the landing spot and found a small little dot". When the images for the first mosaic were acquired, the impact point was poorly illuminated and thus not easily identifiable.
Shan said his colleagues did not take him seriously when he told them that he was trying to find the Lander.
The spacecraft carrying the Vikram lander launched from Sriharikota in southern India on July 22. "(1 km from the landing spot) Lander might have been buried in Lunar sand?".
NASA has pinpointed India's missing Vikram lander through the lens of its Lunar Reconnaissance Orbiter Camera, bringing an end to a three-month search for the fragmented spacecraft. A fresh flyby on November 11 gave a better look at the crash site. "Again, I would wake wake up by 6 am and scan the photos until 8 am before leaving for office", he said. The release spurred people to search the mosaic for any hints of Vikram, which was eventually first identified by Shanmuga Subramanian. "I used that information to discard other false positives", he said.
Shanmuga Subramanian, 33, an IT professional from Chennai, contacted the LRO project.
The point marked with an S is the spec located by Mr Subramanian. "Just have the images open side by side and go through pixel after pixel", he added.
In an email posted to Twitter, LROC deputy project scientist John Keller left no doubt the dot Mr Subramanian saw was part of a lunar crash zone.
"NASA has to be 100% sure before they can go public, and that's the reason they waited to confirm it, and even I would have done the same", said Subramanian.
Subramanian tweeted on Tuesday morning that he received a mail from NASA which acknoweledged his help to find out the lander. Two subsequent image sequences were acquired on October 14 and 15, and November 11.
