Chandrayaan 2: NASA releases photos of Vikram lander 'obscured in lunar highlands' as seen by its lunar orbiter

NASA has released images of the final landing site of the Vikram lander, part of the Indian Space Research Organisation’s Chandrayaan 2 mission. The images, captured by the Lunar Reconnaissance Orbiter’s Camera (LROC) instrument days after crash-landing  near the South Polar region  of the Moon. The NASA satellite carried out an overhead fly-by of the exact location the Chandrayaan 2 orbiter spotted after it lost communication with ISRO during its descent. Even using its most powerful cameras, the lunar orbiter failed to  identify the Vikram lander  in images captured on 17 September, ten days after the lander supposedly crashed and went incommunicado. NASA admitted a week ago that the Vikram lander may not be in the ‘field of view’ of the LRO’s on-board camera. The reason for this is likely “long shadows in the area” that might be obscuring the still-silent Vikram lander, NASA reiterated  in a statement released along with the processed images .

Since then, there has been a lot of uncertainty about exactly where the Vikram lander has ended up, and if it crashed or landed more or less intact. “It will be difficult to find the lander during the current flyover as the angle of the Sun will be low. And, if the lander is close to any relief feature, then the lander will get hidden in its shadow. The LRO will have better chances of getting a good image of the lander during its next flyover,” said Jatan Mehta, a former science officer with TeamIndus, a Bengaluru-based private company that aims to send a lander-rover to the Moon. This next opportunity for the LRO to catch a glimpse of the lander will be on 14 October. Even 20 days after the lander’s ill-fated descent, ISRO continues to keep mum about data and images from the mission’s lone survivor, the orbiter.
