A NASA satellite orbiting the Moon has found India's Vikram lander which crashed on the lunar surface in September, the United States space agency has said, Eurasia Diary reports citing Aljazeera.

NASA made the announcement on Monday, releasing an image taken by its Lunar Reconnaissance Orbiter (LRO) that showed the site of the spacecraft's impact (September 6 in India and September 7 in the US).

A version of the picture was marked up to show the associated debris field, with parts scattered over almost two dozen locations spanning several kilometers.

In a statement, NASA said it released a mosaic image of the site on September 26 (but taken on September 17), inviting the public to compare it with images of the same area before the crash to find signs of the lander.

The first person to come up with a positive identification was Shanmuga "Shan" Subramanian, a 33-year-old IT professional from Chennai, who told AFP that NASA's inability to find the lander on its own had sparked his interest.

"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, adding he was helped by fellow Twitter and Reddit users.

"It was quite hard, but (I) spent some effort," said the self-professed space nerd, finally announcing his discovery on Twitter on October 3.

NASA then performed additional searches in the area and officially announced the finding almost two months later.

"NASA has to be 100 percent sure before they can go public, and that's the reason they waited to confirm it, and even I would have done the same," said Subramanian.
