Chennai techie Shanmuga Subramanian helped NASA find Vikram Lander on Moon’s surface
New Delhi | Jagran News Desk: The American space agency, National Aeronautics and Space Administration (NASA), on Tuesday claimed that they have found the debris of Chandrayaan-2’s ‘Vikram Lander’ on the lunar surface and also released the images of the impact site of Vikram Lander.
The NASA has credited a Chennai-based engineer, Shanmuga Subramanian, for alerting them about the presence of the debris of Vikram Lander on the Moon’s surface. NASA in its statement released today said that ‘the debris first located by Shanmuga is about 750 meters northwest of the main crash site’, and also released images captured by its Lunar Reconnaissance Orbiter (LRO) that showed the site of the spacecraft's impact.
"The debris first located by Shanmuga is about 750 meters northwest of the main crash site and was a single bright pixel identification in that first mosaic," NASA said in a statement.
"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 without elaborating Subramanian's identity.
"Shanmuga Subramanian contacted the LRO project with positive identification of debris. After receiving this tip, the LROC team confirmed the identification by comparing before and after images," the statement further added.
NASA earlier said that it released mosaic images which were taken by its LRO on September 17 and had invited the public to compare it with images of the same before Vikram lander’s crash to find the evidence of the crash.
The Chennai engineer became the first person to come up with a positive identification that showed the debris of the Vikram lander on the lunar surface.
"I had side-by-side comparison of those two images on two of my laptops... on one side there was the old image, and another side there was the new image released by NASA," he said as quoted by news agency AFP, adding he was helped by fellow Twitter and Reddit users.
NASA then performed additional searches in the area and officially announced the finding almost two months later.
"Is this Vikram lander? (1 km from the landing spot) Lander might have been buried in Lunar sand?" Subramanian had tweeted on October 3, tagging NASA and ISRO. On November 17, he tweeted more details with two images of the crash site.

This might be Vikram lander's crash site (Lat:-70.8552 Lon:21.71233 ) & the ejecta that was thrown out of it might have landed over here https://t.co/8uKZv7oXQa (The one on the left side was taken on July 16th & one on the right side was from Sept 17) pic.twitter.com/WNKOUy2mg1

Vikram Lander was scheduled to make a soft-landing near the south pole of the moon on September 7. However, minutes before its scheduled soft-landing, ISRO had lost communication with the lander at 2.1 kilometers above the Moon's surface.
