Spent 7-8 hours each day for 4-5 days on this: Shanmuga Subramanian on discovering debris of Vikram lander

CHENNAI (TAMIL NADU): Shanmuga Subramanian, an amateur astronomer from Chennai who discovered debris of Chandrayaan-2's Vikram lander on the surface of the moon, said that he spent seven-eight hours each day for four-five days and hoped that it would inspire others as well.
"I was able to find something out of the ordinary in a particular spot, so, I thought this must be the debris. I got confirmation from Nasa today," Subramanian told ANI here.
"I spent seven-eight hours each day for four-five days on this. This is something that can be done by anyone with right knowledge. This should inspire a lot of people," he added.
Nasa on Tuesday found Vikram lander of Chandrayaan-2 and released images of its impact site on the Moon, where the spacecraft had lost communication moments before making a soft landing on the far side of the lunar surface in September.
The Nasa posted images clicked by its Lunar Reconnaissance Orbiter (LRO) 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.

It also indicated the impact spot of the lander and an associated debris field created by the crash with blue and green dots respectively.
"Green dots indicate spacecraft debris (confirmed or likely). Blue dots locate disturbed soil, likely where small bits of the spacecraft churned up the regolith. "S" indicates debris identified by Shanmuga Subramanian," the statement said.
"Shanmuga Subramanian contacted the LRO project with a positive identification of debris. After receiving this tip, the LROC team confirmed the identification by comparing before and after images," it added.
"The Lunar Reconnaissance Orbiter Camera team released the first mosaic (acquired on September 17) of the site on September 26 and many people have downloaded the mosaic to search for signs of Vikram. When the images for the first mosaic were acquired the impact point was poorly illuminated and thus not easily identifiable. Two subsequent image sequences were acquired on October 14 and 15, and on November 11.
The LROC team scoured the surrounding area in these new mosaics and found the impact site and associated debris field," the statement continued.
