The engineer, Shanmuga Subramanian, said he examined an earlier NASA photo to locate the debris. The space agency said in a statement that Subramanian first located the debris about 750 meters (half a mile) northwest of the main crash site.
“It took days of work to find the crash site,” Shanmugham said. “I searched around the north of the landing spot and found a small little dot. When I compared it to the Lunar Reconnaissance Orbiter images of the site from the last nine years, I located the debris and reached out to NASA.”
The 33-year-old engineer announced his discovery on Twitter on Oct. 3, after which NASA performed additional searches in the area and made an official announcement. The space agency said that after receiving Subramanian's findings, its team "confirmed the identification by comparing before and after images.”
NASA also said, “Despite the loss, getting that close to the surface was an amazing achievement.” India’s space agency lost touch with the Vikram lunar lander after it crash landed during its final approach to the moon’s south pole to deploy a rover to search for signs of water.
A successful landing would have made India just the fourth country to land a vessel on the lunar surface, and only the third to operate a robotic rover there.
