'space' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'about-turn in forming a link' is the wordplay.
'about turn' becomes 'u' (a 'U-turn' is a kind of turn. I am not sure about the 'about' bit.).
'in' means one lot of letters goes inside another.
'forming' indicates an anagram.
'link' anagrammed gives 'lnik'.
'u' put into 'lnik' is 'LUNIK'.

'in' acts as a link.

(Another definition for lunik that I've seen is " Soviet moon probe".)
