Shanmuga Subramanian, the Chennai-based mechanical engineer deserves a great applaud as he found the debris of Chandrayaan-2’s Vikram Lander, India’s ambitious moon mission, launched by the Indian Space Research Organisation (ISRO) on 22nd July 2019. He had alerted the National Aeronautics and Space Administration (NASA) about his discovery.
The NASA gave credit to Subramanian, 33 years old, for finding Vikram Lander on the moon’s surface. He had posted the picture as evidence on his Twitter account.
Subramanian after locating the Vikram Lander took the pictures by the Lunar Reconnaissance Orbital Camera (LROC) and posted on his twitter account, NASA and Arizona State University (ASU) after confirmation, announced the great efforts of Subramanian and gave the credit to him on Monday (02.12.2019).
Initially, the debris which was located by Shanmuga, was about 750 meters northwest of the main crash site, on the basis of LROC project location, said in a statement by ASU.
NASA said this research was the aftereffect of the first mosaic image shared on September 17 by them of the likely crash site, which was taken by the LROC. Several people had downloaded to look for signs of the Vikram. One of them, Subramanian, contacted the LROC project with positive identification of debris.
After receiving this clue the LROC team confirmed the identification by comparing before and after images,” the ASU said.
When the images for the first mosaic were acquired on September 17, the collision point was poorly illuminated and could not easily be identified. But two image sequences that were acquired on October 14 and 15, 2019 and on November 11, 2019, were better.
The university said that based on Subramanian’s information, the LROC team battered 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 meters.
ISRO chairman K Sivan declared the launch and orbit of Chandrayaan 2 around the moon was perfect but Vikram Lander lost contact with the ISRO following its launch from Chandraayan-2 moon orbiter on September 6 when it tried to make a soft landing near the moon’s the South Pole.
Images of the early findings were first tweeted by Subramanian on October 3 and then on November 17 and in both his posts, he tagged NASA. In the first tweet, he asked “Is this Vikram Lander?” and in the second, he stated, “This might be Vikram lander’s crash site.”
