India: Nasa's LRO Camera Finds Vikram Debris, Chandrayaan-2 Landing Gear, on the Surface of the Moon | India News
In a statement, NASA said, “Vikram land found. An image of the moon with blue and green dots shows Vikram's point of impact and an associated debris field.
The # Chandrayaan2 Vikram lander was found by our mission @NASAMoon, the Lunar Reconnaissance Orbiter. See the… https://t.co/niHBT1STV2

“Green dots indicate spacecraft debris (confirmed or probable). The blue dots locate the disturbed ground, probably where small fragments of the spacecraft have overturned the regolith. "S" indicates the debris identified by Shanmuga. Subramanian, ”the statement read (see image).
While the NASA statement does not specify Subramanian's identity, it does indicate that he contacted Project LRO with a positive identification of the debris.
"... After receiving this advice, the LROC team confirmed the identification by comparing the before and after images," the statement said.
On September 26, the LRO Camera team released the site's first mosaic (acquired September 17), and many people, including Subramanian, downloaded the mosaic to look for signs of Vikram.
When the images of the first mosaic were acquired, the point of impact was poorly lit and therefore difficult to identify. Two subsequent image sequences were acquired on October 14 and 15 and November 11.
“The LROC team scanned the surroundings of these new mosaics and found the impact site (70,8810 ° S, 22,7840 ° E, 834 m above sea level) and The November mosaic had the best scale of pixels (0,7 meters) and the best lighting conditions (angle of incidence of 72 °) “, adds the press release.
The debris first discovered by Shanmuga is approximately 750 meters northwest of the main crush site and constitutes a single bright pixel identification in this first mosaic (1,3 pixel meter, 84 incidence angle °).
The November mosaic best shows the impact crater, radius, and vast field of debris. The three largest pieces of debris each measure approximately 2 x 2 pixels and form a one-pixel shadow.
