It's commonly stated that the moon's year is the same duration as its year and consequently there's a part of the moon that we never see from Earth.
Is that latter part correct, even if the former part is not strictly accurate?
If the day and year are not identical, why do we not see all of the moon eventually?
These questions were brought about by the news that a Chinese spacecraft has landed on the "dark side of the moon". That got me wondering whether the landing was completely autonomous or whether there was another module in orbit that could relay information from Earth (and indeed video back from the landing module.) Does anyone know?
