I noticed this recently where NASA‘s second flyover – https://www.sciencealert.com/india-s-crashed-moon-lander-is-still-missing-and-nasa-can-t-find-it-anywhere and https://www.indiatoday.in/science/story/chandrayaan-2-vikram-lander-not-found-new-nasa-photos-moon-landing-site-1612124-2019-10-23 has not found the Chandrayaan-2 lunar lander. The theories right now are
- It landed in an area covered by shadow even during the lunar day
- It landed outside the expected landing area
At some point, they may find it as they eventually found Israel Lunar Lander Crashed on the Moon April 11, 2019 – Space Saturdays.
