Get away into space, by the way? (6)
I believe the answer is:
escape
'get away' is the definition.
(synonyms)
'space by the way?' is the wordplay.
I cannot really see how this works, but
an anagram of 'space' is 'escap' which is within the answer.
'way?' could be 'e' (Compass direction - East) and 'e' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'into' acts as a link.
Can you help me to learn more?
(Other definitions for escape that I've seen before include "See cap (anag.)" , "Abscond, flee" , "Slip away - leak out" , "Computer key" , "it was great for Steve McQueen!" .)
