Crossword Genius

Space traveller leaves (6)

Ross

I believe the answer is:

rocket

I believe this clue is a double definition.

'space traveller' is the first definition.

'leaves' is the second definition.
(I've seen this before)

(Other definitions for rocket that I've seen before include "A slangy reprimand or a firework" , "Go up suddenly" , "Shoot upwards" , "7 or firework" , "go fast" .)

I've seen this clue in The Times.
