New form of travel in space (8)
I believe the answer is:
interval
'space' is the definition.
(I've seen this before)
'new form of travel in' is the wordplay.
'new form of' indicates an anagram.
'travel'+'in'='travelin'
'travelin' is an anagram of 'INTERVAL'.
(Other definitions for interval that I've seen before include "breather" , "what's between notes?" , "Space of time" , "Hiatus" , "Pause (between acts)" .)
