NASA had published a mosaic of images of the Moon taken after the crash, calling for the public to help find the site by comparing the photo to an earlier shot.
NASA took the evidence he sent them and performed their own study of the images, which were taken by the Lunar Reconnaissance Orbiter, before announcing the findings on Monday. "And that's the thought that led me to search for Vikram lander". There were vertical and horizontal lines with each square marking an area of one square kilometre. This is the first time a publicly-released image has identified the lander's impact site and debris field. Imaging experts have spotted extensive evidence of the crash, including both debris from the craft and places where the collision seems to have stirred up the moon's regolith.
The Indian Space Research Organisation (ISRO) is yet to share their comments on the image publicly. "But then decided that it was too much effort", Shan, who says he has developed multiple tools for weather monitoring and clutter-free viewing of websites on mobile phones, said.
"He went through the image, looking pixel by pixel and found that spot", Petro added. During that time, NASA and the LRO project scientists, had expressed their inability to find the lander as the area in which the lander had crashed was in deep shadows. "I used that information to discard other false positives", he said.
NASA was also keen to point out that the ISRO's mission was still a success. On October 18, he emailed NASA. "But I couldn't email ISRO since I did not have the right contact".
After making the discovery, Shanmuga wrote to Nasa informing it about his findings for which the U.S. space agency took some time to confirm it. I strongly suspect engineers will be examining the LRO data carefully, since the direction and velocity of the impact may give them clues as to what went wrong.
The lander and the rover it had on board may have met a sad fate, but the Chandrayaan-2 orbiter is still in operation and is busy studying the moon in detail from above.
"I made a decision to search around 2×2 sq km area around the expected landing coordinates and concentrated my efforts north of landing point, as Vikram approached the (designated) area from the North Pole", he added.
