NASA has found the crash site and debris of India’s Chandrayaan-2 Vikram moon lander following a tip from an Indian space enthusiast who examined pictures of the area of the moon taken by a US orbiting camera. The site was located by Shanmuga Subramanian, who on his own scoured the pictures taken by the Lunar Reconnaissance Orbital Camera (LROC), NASA and Arizona State University announced on Monday confirming the find.

The first mosaic image of the likely crash site made from pictures taken by the LROC on September 17 was downloaded by several people to look for signs of the Vikram, NASA said. This image shows the Vikram Lander impact point and associated debris field. Green dots indicate spacecraft debris (confirmed or likely). Blue dots locate disturbed soil.

Arizona State University (ASU), where the LROC project is located, said, “After receiving this tip the LROC team confirmed the identification by comparing before and after images.” When the images for the first mosaic were acquired on September 17, the impact point was poorly illuminated and could not easily be identified, it said. This before and after image ratio highlights changes to the surface; the impact point is near center of the image and stands out due the dark rays and bright outer halo.

The university said that based on Subramanian’s tip, the LROC team scoured the surrounding area in the new mosaics and found the impact site and the debris field. The impact site is located at 70.8810 degree S, 22.7840 degrees E, at an elevation of 834 metres, it said. “The debris first located by Shanmuga is about 750 meters northwest of the main crash site,” ASU said. Vikram lost contact with the Indian Space Research Organisation (Isro) following its launch from Chandraayan-2 moon orbiter on September 6 when it tried to make a softlanding near the moon’s south pole. Before and after images show the Vikram impact point. Changes to the surface are subtle and are more easily seen in the ratio image presented above. Photo credit: Nasa
