In a statement, NASA said: "Vikram landed found." An image of the moon with blue and green dots shows the point of impact of Vikram and an associated debris field.
The #grader Chandrayaan2 Vikram was found by our @NASAMoon mission, the Lunar Reconnaissance Orbiter. See the ... https://t.co/niHBT1STV2

"Green dots indicate debris from the spacecraft (confirmed or probable). The blue dots locate the disturbed ground, probably where small fragments of the spacecraft have returned the regolith, "S" indicates the debris identified by Shanmuga. Subramanian ", reads the statement (see image).
Although NASA's statement does not specify Subramanian's identity, she says he contacted the LRO project with a positive identification of the debris.
"... After receiving this advice, the LROC team confirmed the identification by comparing the images before and after," the statement said.
On September 26, the LRO Camera team released the first mosaic (acquired on September 17) of the site 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 discovered the impact site (70,8810 ° S, 22,7840 ° E, 834 m altitude) and November's mosaic had the best pixel scale (0,7 meter) and the best lighting conditions (angle of incidence of 72 °), "the statement added.
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 shows the impact crater, the radius and the vast debris field. The three largest debris each measure about 2 x 2 pixels and form a shadow of one pixel.
