Tweets and news suggest that Chandrayaan-2 lander may have been located, using thermal imaging by the Chandrayaan-2 orbiter.
K Sivan, chief of the Indian Space Research Organisation, said today (Sept. 8) that the Vikram lander was located by Chandrayaan-2 and efforts to restore contact the probe will continue for at least 14 days, according to a Times of India report.
"We have found the location of Lander Vikram on [the] lunar surface and Orbiter has clicked a thermal image of Lander," Sivan told the ANI news service in an interview, adding that attempts to communicate with the lander are ongoing.
n an exclusive interview, ISRO Chairman K. Sivan told India Today TV that the Chandrayaan 2 orbiter had sent back a thermal image of the location of the Vikram lander, and they're now attempting to contact it.

K. Sivan, the director of the Indian Space Research Organization, told national news outlets that a thermal image had been taken by the Chandrayaan-2 mission’s orbiter. He said it was still unclear whether the lander was damaged, though he expected it had experienced a “hard landing.”
“We are trying to establish a contact,” he was quoted as saying by Asian News International.
The thermal image from the orbiter has not been released publicly. A spokesman for the space agency did not respond to requests for comment on Sunday.
Question: Why a thermal image? Is there expected to be better contrast than in visible light? Does Chandrayaan-2 not have a visible light camera? Wouldn't the diffraction-limited resolution at thermal infrared (5-20 microns) be much worse than in the visible (0.4-0.7 microns)?
