Look, new space suit at last (6)
I believe the answer is:
aspect
'look' is the definition.
(synonyms)
'new space suit at last' is the wordplay.
'new' indicates an anagram.
'at last' indicates one should take the final letters.
The final letter of 'suit' is 't'.
'space' anagrammed gives 'aspec'.
'aspec'+'t'='ASPECT'
(Other definitions for aspect that I've seen before include "Prospect, facet" , "Face" , "front" , "Particular or distinct element, of a problem say" , "Particular part or element, of a problem say" .)
