Where did Luna 9 land on the moon?

SMRTR summary

Luna 9, humanity's first successful lunar lander from 60 years ago, remains missing despite advanced orbital mapping technology. The Soviet spacecraft is too small for current cameras to detect among lunar debris, even though landing coordinates were published. International teams of "space archaeologists" using machine learning have identified promising candidate sites roughly 25 kilometers from the original coordinates, with India's Chandrayaan-2 spacecraft planned to confirm the discovery in March 2026.
