It took a turn in forming a link with the Moon (5)
I believe the answer is:
lunik
'the moon' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'it took a turn in forming a link' is the wordplay.
I cannot quite see how this works, but
'turn' could be 'u' (a 'U-turn' is a kind of turn) and 'u' is found within the answer.
an anagram of 'link' is 'lnik' which is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'with' is the link.
Can you help me to learn more?
(Another definition for lunik that I've seen is " Soviet moon probe".)
