Among them was Shanmuga Subramanian who contacted the LRO project with positive identification of debris. However, when the lander crashed it kicked up enough dust and debris that the changes it made to the lunar surface were visible from above.
There is now direct evidence of this: NASA's Lunar Reconnaissance Orbiter (LRO) took images of the site, and after receiving a tip from an Indian space enthusiast who found some evidence of debris in the images, the LRO Camera team positively identified the impact site and debris from the spacecraft. "This portion of the Narrow-Angle Camera mosaic was made from images M1328074531L/R and M1328081572L/R acquired November 11", said a statement from NASA. So, I took up this challenge. 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.
He says he did not use any advanced software tools apart from basic image viewing tools. However, it lost contact with ISRO minutes before the scheduled landing and crashed. "It's quite big but it is a little sad at the same time because we all expected Vikram to land on the surface", Subramanian told the television channel.
"I narrowed my search to two square kilometres", he told the broadcaster. During the search, Shan found a tiny dot which he compared with previous images of that area of the south pole. According to NASA's release, Shanmuga Subramanian, a 33-year-old techie is the first person who has come up with the results. "Again, I would wake wake up by 6 am and scan the photos until 8 am before leaving for office", he said.
Mr Subramanian had first spotted it on October 3, and tweeted the location on November 17. "(1 km from the landing spot) Lander might have been buried in Lunar sand?". Then on October 18, he emailed Nasa about his findings. "NASA confirms finding?' Can't we give enough credit to our own tech wizards?", tweeted Anand Mahindra. The exact location of the debris remained a mystery until Monday, when NASA released images showing the main crash site as well as scattered wreckage. "See the first mosaic of the imapct site".
The point marked with an S is the speck located by Mr Subramanian.
In the image below, the green dots map out the spacecraft debris, while the blue dots indicate areas where the lunar soil was disturbed by the impact of the crash. Its debris was strewn across about 750 metres of the crash site. "Congratulations for what I am sure was a lot of time and effort on your part".
The British firm has high ambitions for when it reaches the moon, including helping to set up a permanent base. Within days, he wrote to the US Space agency sharing the details of his recent discovery.
