A Russian Moon Landing that was attempted on October 7, 1965 is believed to have failed.
From Reuters:Signals from Luna 7, Russia’s two-ton space craft designed to reach the moon stopped at eight minutes past 11 last night, the time scheduled for impact. Sir Bernard Lovell, who was in charge of tracking operations at Jodrell Bank, Cheshire, said : We can’t say at the moment what this means. We don’t know whether it is a crash landing or whether it is continuing to work, and the Russians have deliberately switched off the signals.” Later he said that all the evidence indicated that Luna made a destructive impact on the moon. He went on:— “It is impossible to do more than guess at what, if anything, has gone wrong. but out assumption was that the Russians intended to make a soft landing of instruments on the lunar surface ” On that assumption the final stages of firing the retrorockets were only partially successful.”
