NASA has found no evidence of Chandrayaan-2’s Vikram lander in the images captured during a latest flyby of its Moon orbiter of the lunar region where India’s ambitious mission attempted a soft landing, the US space agency said. On September 7, Indian Space Research Organisation (ISRO) attempted a soft landing of Vikram on the uncharted lunar south pole, before losing communication with the lander.
“The Lunar Reconnaissance Orbiter imaged the area of the targeted Chandrayaan-2Vikram landing site on October 14 but did not observe any evidence of the lander,” Noah Edward Petro, the Project Scientist for the LRO mission, told PTI in an exclusive email interaction.
Petro said that the camera team carefully examined the images and employed the change detection technique — using a ratio of an image from prior to the landing attempt to the one acquired on October 14. This approach, he said, is used for finding new meteorite impacts on the Moon that also helped locate the recent Beresheet lander.
“It is possible that Vikram is located in a shadow or outside of the search area. Because of the low latitude, approximately 70 degrees south, the area is never completely free of shadows, John Keller, Deputy Project Scientist LRO Mission, told PTI….

Chandrayaan-2 is about to begin its final descent to pull off a historic soft landing on the lunar surface. The India’s second moon mission has gone through a long journey dotted with many events in close to 12 years since being conceived in 2007. Starting from Chandrayaan 1, here’s a list of all the major events that led Chandrayaan-2 to where it is today:
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.
November 26, 2008
The indigenous Terrain Mapping Camera, which was first activated on October 29, 2008, acquires images of peaks and craters. This comes as a surprise to Isro officials because the Moon consists mostly of craters….
