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.
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.”One of them, Subramanian, contacted the LROC project with a positive identification of debris, it said. 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.
But two image sequences were acquired on October 14 and 15, and on November 11 were better. 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….

April 2003
Over 100 eminent Indian scientists in the fields of planetary and space sciences, Earth sciences, physics, chemistry, astronomy, astrophysics and engineering and communication sciences discuss and approve the Task Force recommendation to launch a probe to the moon.
August 15, 2003
Prime Minister Atal Bihari Vajpayee announces the Chandrayaan mission during his Independence Day speech.
November 2003
The government gives its approval for the moon mission.
October 22, 2008
Chandrayaan-1 launched successfully from Satish Dhawan Space Centre, Sriharikota using four-stage PSLV rocket.
