NASA's Moon-orbiting spacecraft has found the debris of Chandrayaan 2's lander Vikram on the surface of the Moon, the US space agency confirmed on Tuesday.
The finding comes nearly three months after India's ambitious mission made a hard landing near the uncharted lunar south pole. On September 7, Indian Space Research Organisation (ISRO) attempted a soft landing of Vikram on the Moon. But ISRO lost contact with Vikram shortly before the scheduled touchdown.
NASA released an image taken by its Lunar Reconnaissance Orbiter (LRO) that showed the site of the spacecraft's impact (September 6 in India and September 7 in the US) and associated debris field, with parts scattered over almost two dozen locations spanning several kilometres.
In a statement, NASA said it released a mosaic image of the site on September 26, inviting the public to search it for signs of the lander.
Indian Engineer Shanmuga Subramanian contacted NASA's project after which, the US space agency confirmed the identification of debris by comparing before and after images.
"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 the impact point was poorly illuminated and thus not easily identifiable," NASA said in a statement.
The two subsequent image sequences were acquired on October 14 and 15, and on November 11, NASA said.
The LROC team scoured the surrounding area in these new mosaics and found the impact site (70.8810 degrees South, 22.7840 degrees East) and associated debris field.
According to NASA, the November mosaic had the best pixel scale (0.7 metre) and lighting conditions (72 degrees incidence angle).
"The debris first located by Shanmuga is about 750 meters northwest of the main crash site and was a single bright pixel identification in that first mosaic," NASA said in a statement.
The November mosaic shows best the impact crater, ray and extensive debris field, NASA said, adding that the three largest pieces of debris are each about 2x2 pixels and cast a one-pixel shadow.
Ever since ISRO lost contact with Vikram, NASA has made several attempts to locate the Chandrayaan-2 lander with the help of its Lunar Reconnaissance Orbiter.
The LRO flew over Vikram's landing site once on September 17 and next on October 14.
The ambitious Chandrayaan-2 mission to the Moon was launched in July. If the spacecraft had reached the surface in one piece on September 7, India would have been only the fourth country to successfully put a lander on the Moon.
The main spacecraft, which remains in orbit around the Moon, dropped the unmanned lander Vikram for a descent that would take five days, but the probe went silent just 2.1 kilometres above the surface.
Days after the failed landing, the ISRO said it had located the lander but hadn't been able to establish communication.
