A Canadian scientist has solved a 37-year-old lunar mystery. The astronomy professor has found the final resting place of the long-lost Soviet moon rover which disappeared four months after landing on the moon in 1973. The scientist examined the images released by NASA this week and found that the rover made the longest trek of any traveller on a celestial body but eventually got stuck in a crater. Its radiator got jammed with soil which led it to overheat and stop working. The Lunokhod-2 was the second Soviet rover to land on the Moon where it will now stay, according to scientists, for the rest of time.
